BMW Petrol Engine Timing Chain Replacement (N13, N20, N55, S55 B58)
Note: There is a 5% admin fee on finance options such as Klarna or Clearpay/Afterpay
BMW does not specify a fixed replacement interval for timing chains.
That’s because, unlike timing belts, chains are designed to last the lifetime of the engine — in theory.
However, in reality, certain BMW engines are prone to premature wear or failure, meaning the chain may need replacement well before 100,000 miles. We often see timing chains needing replacement at 60,000 miles onwards.
We offer timing chain inspection and replacement services using OEM or upgraded components for most BMW petrol and diesel engines.
Our experienced technicians follow BMW’s exact procedures, ensuring your engine is timed perfectly and runs like new.
Our timing chain repair includes:
Genuine IWIS main and oil pump chains.
Timing chain guides & tensioners
Camshaft and pump sprockets.
Crankshaft oil seal.
Rocker cover gasket.
Associated gaskets & hardware.
Engine oil and filter.
Engine coolant.
Digital service history updated on bmw online database.
Full vehicle health check.
We replace all necessary chains and sprockets specific to your engine—not just the timing chains. This is essential for a long-lasting repair, as many engines are prone to oil pump chain and sprocket failures. These components are often overlooked by repairers offering lower-cost solutions, increasing the risk of future failures.
Note: in some cases after timing chain replacement on the engines above we have found the vanos components (valvetronic motor, eccentric shaft, camshaft gears) to not work correctly, as they wear internally. Therefore can also require replacement for the engine to run correctly after timing chain replacement.
Common additions to this service are (price varies depending upon the engine):
Valvetronic motor & eccentric shaft.
Conrod bearings w sump baffle.
ZF transmission service.
Valve cover replacement, discounted to parts only price (no labour cost).
Differential oil change.
Clutch or clutch and dual mass flywheel replacement.
Upgrade to major engine service.
“X” vehicles are £150 additional to any price quoted (X1,X2,X3,X4,X5,X6 etc).
We will carry out a full inspection of your vehicle and advise of any additional recommendations while replacing the timing chain. Completing any necessary work at the same time can often reduce labour costs and help prevent more expensive repairs in the future.
All above prices include parts, labour and VAT.
Things to note:
If the timing chain has snapped this will be additional cost to repair, we will inspect and advise depending on the extent of the damage.
Does not include aircon regas.
Collection of vehicle can be arranged at additional cost.
