BMW X1 M35i Timing Chain Failure (U11, N47)
If your X1 M35i is a pre-2015 model with the N47 diesel engine — that's the early U11 generation — timing chain failure due to chain guide wear is a well-documented pattern, subject to NHTSA recall 18V-755. We replace timing chains, guides, and tensioners as standard on every N47 rebuild.
The later U11 (2015-onwards) and U11 generations use a different engine, the B47, which is significantly more reliable and doesn't share this specific issue.

Every X1 M35i is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR X1 M35i ENGINE
We rebuild your existing X1 M35i engine – strip it down, pressure-test it, and replace all worn or damaged components with updated OEM parts (timing chains, guides & tensioners on the N47). Near-new performance with a 12-month unlimited-mileage warranty.
From £2,200RECONDITIONED X1 M35i ENGINES
A full strip-down, inspection and replacement of worn parts rather than a straight swap. If that's what you're after, our rebuild service is exactly that.

LOOKING FOR A USED ORREPLACEMENT ENGINEINSTEAD?
We supply low-mileage, VIN-matched used units too. However, most BMW owners choose a rebuild once they realise it removes compatibility risk, keeps their original engine number, and often works out cheaper than fitting an unknown used engine.

ABOUT THE BMWX1 M35i ENGINE
The X1 M35i has been a mainstay of the X1 diesel range since 2012, spanning two generations under one badge. Early U11 models from 2012 to 2015 use the N47, a 2.0-litre diesel that's part of a family known for a specific timing chain issue. From late 2015 onwards, across both the U11 and later the U11, the X1 M35i switched to the B47, a newer, significantly more reliable unit that doesn't share the N47's timing chain concerns. Knowing which one your car has matters, because the components and the known wear pattern differ — which is exactly why we confirm your exact engine by registration before quoting.
The X1 M35i is no longer in production, but we continue to rebuild and replace engines for every one still on the road.
BMW X1 M35i ENGINE CODES
N47 (U11, 2012–2015)
A 2.0-litre diesel fitted to the early U11 X1 M35i. Known for timing chain failure due to chain guide wear — see the callout above. We replace timing chains, guides, and tensioners as standard on every N47 rebuild.
Check Your N47 X1 M35iB47 (U11, 2015–2019 / U11, 2019–2024)
The later 2.0-litre diesel, fitted from 2015 onwards. A different design from the N47 that is significantly more reliable and doesn't share its predecessor's timing chain issue.
Check Your B47 X1 M35iBMW X1 M35iENGINE COMPATIBILITY
Because the X1 M35i spans two distinct engines across two generations, fitting the wrong replacement — or assuming an N47 part will work on a B47 car — risks a compatibility problem that's expensive to unpick. Before we quote or supply anything, we confirm:
Your exact engine code (N47 or B47) via registration or VIN
Your generation (U11 or U11)
Drivetrain and ancillary specification
Any electronics or ECU considerations specific to your exact build
This is why we always start with your registration rather than a generic X1 M35i quote — it protects you from paying for parts that don't fit your actual car.
