BMW Alpina B8 Timing Chain Failure (G14/G15/G16, N47)

If your Alpina B8 is a pre-2015 model with the N47 diesel engine — that's the early G14/G15/G16 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 G14/G15/G16 (2015-onwards) and G14/G15/G16 generations use a different engine, the B47, which is significantly more reliable and doesn't share this specific issue.

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 BMWAlpina B8 ENGINE

BMW 320d engine and sedan

The Alpina B8 has been a mainstay of the 8 Series diesel range since 2012, spanning two generations under one badge. Early G14/G15/G16 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 G14/G15/G16 and later the G14/G15/G16, the Alpina B8 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 Alpina B8 is no longer in production, but we continue to rebuild and replace engines for every one still on the road.

BMW Alpina B8 ENGINE CODES

N47

N47 (G14/G15/G16, 2012–2015)

A 2.0-litre diesel fitted to the early G14/G15/G16 Alpina B8. 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.

B47

B47 (G14/G15/G16, 2015–2019 / G14/G15/G16, 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.

BMW Alpina B8ENGINE COMPATIBILITY

BMW touring in workshop

Because the Alpina B8 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 (G14/G15/G16 or G14/G15/G16)

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 Alpina B8 quote — it protects you from paying for parts that don't fit your actual car.
