## The story

*What this car is, and the six questions that decide whether the one you are looking at is a good buy*


## 1 · Who built it, and what they built

Somebody had to build the sensible one.

The E60 5 Series is remembered for two cars: the M5 with the V10, and the styling nobody could agree
about. What almost nobody remembers is that the ordinary 530i had a naturally aspirated straight six
under the bonnet, and that from 2005 BMW put something
in it that no manufacturer had ever put in a water-cooled engine before.

This is the boring 5 Series. It is also, twenty years on, the only one you can still afford to run.

### The engine, and there are three of them

**This is the thing to understand before anything else: the badge on the boot says 530i, and it
covers three completely different engines.**

| Years | Engine | Output |
|---|---|---|
| 2003–2005 | **M54B30** | 231 PS at 5,900 rpm |
| 2005–2007 | **N52B30** | 258 PS at 6,600 rpm |
| 2007–2010 | **N53B30** | 272 PS at 6,700 rpm |

All three are naturally aspirated straight sixes. All three sound similar and drive similarly. And
they do not cost the same to own — not remotely — because the last one has direct injection, and on
this engine that means a high-pressure fuel pump and piezo injectors.

**And the middle one is the interesting one.** The **N52** block is made from **magnesium and
aluminium together**, and it was the first water-cooled engine ever to use a magnesium-aluminium
composite block. **The N53 that replaced it got the same block** — and when BMW moved to turbocharging, the idea went with the naturally aspirated sixes.
It is also one of the last naturally aspirated six-cylinder 5 Series: the F10 that replaced it still
offered the N53, in a European 530i built until 2013.

So the sentence that describes this car is not about power. It is that **you can still buy a
magnesium-block naturally aspirated straight six for the price of a small hatchback**, and that which
one you buy is decided by a two-year window in the registration document.

### The transmissions

The **ZF 6HP** six-speed automatic on most cars, and a six-speed manual on some. And one that is easy
to miss: BMW also offered a six-speed **SMG** automated manual on the M54 and N52 cars. This guide does
not cover the SMG, so if the car you are looking at has one, have the gearbox assessed separately by
someone who knows it.

### And what this guide is arranged around

Not one big failure, because there isn't one. **It is arranged around the question of which engine you
are looking at**, and then around the ordinary running of a car that BMW sold by the hundred thousand
and that a lot of people ran on the cheapest possible servicing because they did not own it.

That last part is why the spread in condition at the same price and mileage on this model is wider
than on anything else in this series. Which is bad news if you buy on price and very good news if you
buy on paperwork.

### How the figures in this guide work

**How much work each job is, not what it costs.** Every point in this guide carries an effort — an hour
or two, half a day, a day, two or three days, or a week or more in the workshop — plus a line saying
whether the money sits in the part or in getting to it.

**There are no prices, and that is deliberate.** What a job costs depends on which country you are in
and which workshop you walk into, so a figure I cannot verify is worse than no figure. If you want
money, ask any workshop one question — *what is your hourly rate?* — and every hour in this guide
becomes your own number, in your own currency. One question, and the answer is actually true for you.

None of this is advice about one particular car, because I have not seen the car you are looking at.
Have every one of them inspected before you buy, by someone who knows this engine.

## 2 · The six questions that decide whether *this* car is a good buy

Six questions, and the first one is not about the car's condition at all.

**1 · Which engine is in it?**
Check the registration and the build date. **M54 up to 2005, N52 from 2005, N53 from 2007** — and on
a 2007-on car the engine code as well, because in countries with high-sulphur fuel the N52 stayed on
until 2010. This is
the single most important thing you will establish about a 530i, because the N53's fuel system is a
category of expense that does not exist on the other two. If you have the choice and everything else
is equal, the N52 is the one to buy.

**2 · Has the electric water pump been done?**
The N52 and N53 use an electric water pump rather than a belt-driven one, and its failure mode is the
problem: **it stops without warning.** On the N52, reports cluster in a fairly narrow mileage window, and
the usual advice is to replace it before it fails rather than after. Ask for the invoice. "It's never given
trouble" is not an answer to this question.

**3 · Does it rattle from the front of the engine on a cold start?**
A noise on a cold start has more than one possible cause on this engine, with two different bills —
and a specialist guide and BMW's own bulletins do not point at the same one. So note the noise and
where it comes from — the noise alone does not settle it. Which noise belongs to which fault, and
what does settle it, is in the buying guide.

**4 · Which valve cover has it got?**
Not *whether* it has been done — *which one it is.* The N52 had two different covers over its life,
in two different materials, and each fails in its own way. Two different parts, two different
failures, and they are not interchangeable without rebuilding the ventilation plumbing. The N53 has a
third cover of its own.

**5 · On an N53: what has been done to the fuel system?**
High-pressure pump and injectors. The pump is the same part as on BMW's twin-turbo N54, where its
failures led to legal action in the United States. The piezo injectors are the N53's known expensive
item. This is the most expensive thing on a 530i and it exists on one engine out of three.

**6 · What has already been paid for?**
On a car that spent its first years as somebody's company car, the folder tells you more than the
odometer does. The water pump, the valve cover and the fuel system all leave no trace except on paper.

### What the honest answer to all six looks like

On a documented N52 car, an owner gets through **roughly a third of the list in the first two years,
and none of the heavy jobs** — a handful of half-days spread over two years. On an undocumented N53,
the fuel system alone can be more than the car is worth.

That is the whole spread on this model, and it comes down to two lines in the registration document
and one folder of invoices.

**And one sentence that applies here more than to any other car in this series: the cheapest 530i on
the market is usually the wrong engine with no paperwork.** The guide is mostly about how to tell,
before you drive out.

Those six answers are only useful if you know what is behind them. The buying guide takes each of these six
apart, adds the things that are simply twenty years old, and gives every one of them how much work it
is, what tells you about it at a viewing, and whether it has to be done now or can wait years. It ends
with a card you print and take with you, in the order you do it, including the one moment at a viewing
that comes only once: the cold start.

## 3 · Which years, which specification

Built from **July 2003 to 2010**, as the **E60** saloon and the **E61** Touring.

**The engine split is the whole chapter.** M54B30 until 2005. N52B30 from 2005. N53B30 from 2007,
except in countries with high-sulphur fuel, where the N52 stayed until 2010. If
you take nothing else from this guide, take that — and take the fact that the badge is identical on
all three.

**The facelift is March 2007**, for the 2008 model year: revised lights and bumpers and a much better
interior. The iDrive computer changed later. With the large navigation system, the earlier cars have
the **CCC**, which can reboot itself and go black, and BMW began replacing it with the **CIC** in
September 2008; without that system, the car has a smaller unit, M-ASK, and neither applies. So a late car is materially
nicer to live with, and it is also more likely to have the N53. Those two pull in opposite directions, and this is the compromise you have to
make consciously rather than by accident.

**What to establish per car:**

*The engine, from the build date and the registration.* First. Always.

*Whether the water pump has been done*, and when.

*Which valve cover*: the N52 had two, and the N53 has its own.

*Which iDrive*: CCC, CIC, or the smaller M-ASK on a car without the large navigation system.

*Saloon or Touring.* The E61 adds a tailgate wiring harness that breaks conductors internally, a
panoramic roof that leaks when the drains block, and self-levelling rear air suspension. All three are
known, all three cost money, and none of them exists on the saloon.

*And whether it has Active Steering or EDC.* Not every car does. On the ones that do, the modules are
expensive, and a warning is not always what it seems.

Beyond that, look for a car nobody has modified. Factory wheels, standard ride height, the original
exhaust. On a car this cheap relative to its original price, an unmodified example usually means an
owner who understood what he had.

## 4 · What it is worth

This is the hardest thing to establish on your own and it does more than anything else to decide
whether you buy well. I am not going to give you a price list — it varies by country and by month, and
an out-of-date number is worse than no number. I am going to give you the method.

**On this car, establish the engine before you look at the price.** A 2008 car and a 2006 car with the
same badge, the same mileage and the same asking price are not the same purchase, and the market
frequently prices them as though they were. That is the single biggest opportunity on this model, and
it exists because most buyers do not know there were three engines.

**There are three kinds of car for sale, and each one deserves a different offer.**

*The documented car.* Full history, invoices tied to readings, and an owner who knows when the water
pump was done. Asking price at the top of the market and usually a bargain in disguise.

*The tidy car with no paperwork.* Drives well, looks well, and the owner says everything has been done.
Dangerous on this car in a specific way: the water pump gives no warning, so "it's never given trouble"
is compatible with it failing next week.

*The project.* Known work, price adjusted to match. Be careful with an undocumented N53 here — a fuel
system on that engine can exceed what you paid.

**How to set the three against each other.** Take the asking price, work through both lists, and add up
what is coming in the first two years. Call that the entry price and compare entry prices rather than
asking prices.

**And one thing that is specific to this model.** These were sold in enormous numbers as company cars,
and a lot of them were serviced as cheaply as possible by people who did not own them. The spread in
condition at the same price and mileage is therefore wider than on anything else in this series. Buy
the folder, not the car.

**Where to look:** your country's big classified sites, the BMW specialists, and the auction sites.
Follow the market for a month before you go and see anything. And pay attention to how long cars sit: a
car advertised for four months is usually a car that several people have inspected.

## 5 · What it is actually like to own one

Nobody looks at it, and after a while you stop wanting them to.

A 530i is a large, quiet, softly damped saloon that does three hundred kilometres of motorway without
asking anything of you, and then turns out to have a naturally aspirated straight six that pulls
cleanly to nearly seven thousand revs. The noise is not loud. It is smooth and slightly metallic and it
arrives from somewhere behind the dashboard, and it is the sound of an engine architecture that BMW
spent forty years perfecting and then abandoned.

**And it revs.** That is the thing you notice against anything modern. A turbocharged six gives you
everything at two thousand and nothing after five. This one keeps going, and the last thousand revs are
the best part. You use them because they are there.

**What it costs you in attention.** More than a modern car, and mostly in electronics rather than
mechanics. Keep a good battery in it, get warnings read out rather than guessed at, and do the water
pump before it does you.

**And it drinks less than you think.** A three-litre naturally aspirated six in a big saloon is not
economical, but it is a long way from the V8 in the same shell. On a car this size that difference is
what makes it usable as an only car.

**What it gives back.** A big BMW saloon with one of the last naturally aspirated sixes BMW built, for the
price of a small hatchback, that nobody notices and nobody covets. That is not an investment and you should not call it one. In an N52 or N53 it is a magnesium-blocked straight six that revs to seven thousand, hidden in the most anonymous car BMW ever sold.

## The buying guide — €24

Everything above is what the car is. This is what you check.

Eight faults that belong to these engines, taken apart one by one, with
how much work each repair is and how to tell which of them you are looking at.
Seventeen things that are simply twenty years old, every one
with how much work it is, what tells you about it at a viewing, and whether it has to be done now,
within a year or two, or not at all. Where corrosion on this car actually costs money, which is under it rather than on it, and the two water problems that belong to the Touring. Which of the three engines you are buying — M54, N52 or N53 — what each one costs you that the others do not, and the check that settles it: the build date, and on a car from 2007 on the engine code as well. The viewing in twelve steps, including the
cold-start moments that come only once. The sentences you say to the seller, and how to build an
offer out of what you found.

And a card you print and take with you — sixty-five lines, in the order you do them.
That comes as a separate file, because nobody wants to print a whole guide to take a few pages to a
car park.

### This is what one of the seventeen looks like

**4 · Pixel loss in the instrument cluster**
Repaired per display
*How you notice it:* black blocks or missing segments. Cycle the menus so you see the whole area.

If it does not bother you, leave it. Plenty of owners live with it for years.

### And this is how the card reads

- [ ] 1 · The cold start · *stand behind the car*
- [ ] 2 · The coolant · *the most valuable question on this car*
- [ ] 3 · The rest of the engine bay, cold
- [ ] 4 · Inside, ignition on · *the long step on this car*
- [ ] 5 · The boot, floor out
- [ ] 6 · Round the outside

### What €24 buys, put next to what it saves

The electric water pump **gives no warning at all — it simply stops**, and on an aluminium head that is not a repair you want. And on the N53, the piezo injectors are the most expensive thing that can happen to a 530i — on the other two engines they do not exist. The guide is **€24**. It will not stop any of that from being needed — but it does
tell you which of them you are looking at before you agree a price, and that is the whole of the
difference between paying for a car and paying for someone else's postponed maintenance.

### Why there are no prices in it

Because a price we cannot verify is worse than no price, and because a price would be wrong for most of
the people reading this anyway. Workshop rates across Europe differ widely, and so do parts prices. A quote from a specialist in one country tells you nothing in another.

**What does not change is how much work a job is** — that follows from what has to come off the car.
So every point in the guide says whether it is an hour or two, half a day, a day, two or three days, or a
week or more in the workshop, with a labour figure where a source gives one. And it says whether the money sits in
the part or in getting to it, which is what lets you tell a fair quote from a bad one.

If you want a figure, ask any workshop one question — *what is your hourly rate?* — and every effort
level in the guide becomes your own number, in your own currency. One question, and the answer is actually true
for you.

### How this guide was put together

Because you should know before you pay for it.

- Every fault and symptom comes from a source the guide names, the manufacturer's own documents first. The
  effort levels are our assessment, unless a source gives the hours.
- Where this guide rests on less evidence than usual — the bodywork of this model — it says so, instead of dressing up ordinary age checks as a weak-point list.
- The effort of every job is counted item by item and checked against the list before every edition.
- It says as plainly what you can leave alone as what you have to do. Six of the
  seventeen age points start from *leave it*.
