BMW N47 timing chain replacement cost: budget for stock
BMW N47 timing chain replacement cost at independent and main-dealer garages across Europe, labour hours and how to factor it into resale.
· 7 min read
The BMW N47 timing chain replacement cost is typically around €1,500–2,500 at an independent workshop in Germany, because the chain sits at the gearbox end of the engine and the job takes roughly 16–22 hours of labour. Main dealers charge more, xDrive and X models cost extra, and if the chain has already jumped, engine damage pushes the bill to several thousand euros.
What is the BMW N47 timing chain replacement cost?
An N47 timing chain replacement costs around €1,500–2,500 at an independent specialist in Germany, according to auto motor und sport, which puts the typical repair in that range. Prices in other countries move with local labour rates.
A published fixed-price example from a German workshop booking platform shows how the price is built:
| Item | Example |
|---|---|
| Fixed price for rear-wheel-drive models, incl. VAT | €1,850 |
| Surcharge for X models and all-wheel drive, incl. VAT | €550 |
| Included parts | both timing chains, upper sprocket, guide rails, tensioners, seals |
| Included extras | engine oil change, coolant renewal, fault memory clearing |
Other sources quote higher figures, particularly when more parts are replaced, when a main dealer does the work, or when there is already damage. Treat €1,500–2,500 as the normal band for a healthy engine at an independent, and get a fixed quote from your own specialist before you rely on it.
| Scenario | Typical cost level |
|---|---|
| Independent specialist, rear-wheel drive, no damage | about €1,500–2,500 |
| xDrive or X model | add several hundred euros |
| Franchised BMW workshop | higher labour rates, usually above the independent price |
| Chain jumped or broke, engine damage | several thousand euros; often more than the car is worth |
Why does the engine have to come out for the job?
The engine usually has to come out because BMW placed the N47's timing chains at the rear of the engine, between the block and the gearbox. On most engines the chain is at the front, behind a cover that is easy to reach; on the N47 the whole drivetrain is in the way.
German workshop guides put the labour at roughly 16–22 hours. That is why the bill is high even though the parts are not especially expensive. The same access problem is why many owners postponed the job, and why so many N47 cars come to the trade with a rattle.
For car dealers
Know your margin before you buy
MyCarDealer compares any car from an auction or listing with the market in your country and shows the net margin after VAT, transport and costs – and the maximum bid.
Request accessCan the chain be replaced without removing the engine?
In most workshops the standard method is to remove the engine. Some specialists instead remove the gearbox and work on the chain from below with the engine in place. Either way the job remains long and expensive.
Be cautious with very cheap quotes that promise a quick "in-car" fix. Ask exactly which parts are replaced (chains, guides, tensioner, sprockets, seals), whether new or revised parts are used, how many hours are charged and whether there is a warranty on the work. Replacing only the tensioner does not cure a stretched chain.
How to factor the chain cost into your maximum bid
Factor the chain cost into your maximum bid as a reserve deducted from the price you can pay: the full repair cost for a car with a rattle or no history, a partial reserve for a quiet car without records, and nothing extra for a car with a documented replacement.
The cars concerned are mostly cheap, which makes the reserve large relative to value. According to listings tracked by MyCarDealer in Germany, Italy, Belgium, the Netherlands and other EU markets in October 2026, a diesel BMW 3 Series from 2007 to 2014 had a median asking price of about €6,950 at about 230,000 km (1,112 listings). A diesel 5 Series from 2010 to 2014 had a median of about €9,300 (954 listings), and a diesel X3 from the same years about €10,500 (444 listings).
Worked example for a 3 Series with an audible rattle (simplified, before VAT on the margin):
| Line | Amount |
|---|---|
| Expected retail price | €6,950 |
| Target margin | −€1,000 |
| Reconditioning, service, tyres | −€700 |
| Transport | −€300 |
| N47 chain replacement | −€2,000 |
| Maximum purchase price | €2,950 |
Without the rattle and with a documented chain replacement, the same car could justify a purchase price around €4,950. That gap is why reading the history matters more than the badge. MyCarDealer's free valuation gives the market price in your country and the maximum bid after VAT, transport and costs; the chain reserve is your own deduction on top.

Is a replaced chain a selling point for retail customers?
A replaced timing chain is a real selling point for retail customers, as long as you can show the invoice. Buyers who research the N47 know about the problem, and a car with the work done removes their main objection.
How to use it:
- Put "timing chain replaced at X km, invoice available" in the listing text.
- Keep a copy of the invoice in the car's file and show it at the viewing.
- Mention which parts were renewed and whether the workshop gave a warranty.
- Price the car slightly above comparable untouched cars, but stay within the market range; buyers compare.
On high-mileage cars, the chain replacement often decides whether a buyer chooses your car or a cheaper one. See our guide to high mileage car value for how buyers weigh mileage against history.
Should you do the chain before resale or sell the car as it is?
Doing the chain before resale makes sense when the car has an audible rattle and is worth enough to sell to a retail customer after the repair. Selling as it is makes sense for low-value cars where the repair would exceed the margin, typically into the trade or for export.
Rules of thumb that dealers use:
- Rattle and retail value comfortably above the repair cost plus margin: do the job and sell it with the invoice.
- No rattle, no records: sell with a clear description, or do the job if you offer a warranty.
- Low-value car with rattle: sell to the trade with disclosure.
- Running problems or warning lights: check for engine damage before deciding; a jumped chain can turn a repair into an engine replacement.
Whatever you decide, disclose known faults honestly; your legal obligations to consumers depend on the country, and a hidden chain rattle is exactly the kind of fault that comes back as a complaint. The N47 timing chain guide explains how to recognise affected cars and symptoms.
Frequently asked questions
How long does an N47 timing chain last?
It varies widely. Some chains rattle before 100,000 km, while others reach much higher mileages, particularly with short oil change intervals and mostly long trips. Engines built from March 2007 to January 2009 are the most at risk.
Can the N47 timing chain be replaced without removing the engine?
Most workshops remove the engine for the job. Some specialists remove the gearbox instead and work on the chain in the car. Either way, the labour time is roughly 16–22 hours.
What years were N47 timing chains affected?
The N47 was built from 2007 to about 2014–2015. The most seriously affected engines were produced between 1 March 2007 and 5 January 2009, but failures occur across the whole production run.
At what mileage does the N47 engine typically fail?
There is no typical failure mileage. Chain problems have appeared both below 100,000 km and well above 200,000 km. Listen for the rattle and check the history rather than relying on the odometer.
Is replacing only the tensioner enough?
No. If the chain has stretched, replacing only the tensioner does not solve the problem. A proper repair replaces the chains, guides, tensioner and related parts together.
