BMW diesel work is some of the most common we do. Common engines we may see include the N47, N57 and B47 four-cylinder and six-cylinder diesels across the 1, 3, 5, X3 and X5 series. The N47 family is well known for timing chain wear at the back of the engine — chains rattle on cold start before they snap, and prompt replacement avoids cylinder head damage.
We carry out independent BMW diagnostics, EGR cooler replacement, DPF cleaning, AdBlue repairs, swirl flap remediation, and full timing chain replacement on the N47 / N57 platforms. Diagnostics use manufacturer-protocol equipment.
BMW timing chain replacement on the N47 family is a gearbox-out job — labour-heavy but routine for us. We do it properly and provide a written quote first.
Yes — independent diesel specialist work on BMW. Diagnostics, DPF, AdBlue, EGR, turbos, timing components and engine work where suitable.

Yes — clutch and dual mass flywheel replacement is routine. We inspect the DMF before recommending replacement, so you don't pay for parts you don't need.
The classic sign is a metallic rattle on cold start that fades after a few seconds. Cam/crank correlation fault codes (P0016 family) on diagnostic data confirm chain stretch. Don't ignore it — a snapped chain on the N47 typically causes severe cylinder head damage.
