DIAGNOSIS

Signs your 4MATIC transfer case is failing

01

Shudder on full lock or low-speed manoeuvres

The most common symptom — worn multi-plate clutch pack losing grip under load.

02

Clicking or grinding noise that rises with road speed

Rises with road speed rather than engine revs — points to internal gear, chain or bearing wear.

03

4x4 / AWD / ABS warning lights together

Triggered when the transfer case control module detects a fault in the clutch actuation.

04

Fluid never changed past 60,000–80,000 miles

The transfer/rear-axle fluid degrades over time even though it's often listed as long-life — a common cause of premature clutch and chain wear.

HOW WE DO IT

Exchange basis — no waiting for a rebuild

STEP 01

Diagnose by VIN

Send your 17-digit VIN and symptoms — we confirm the exact SEC / GA722 / DCS / DCD / VG150 variant fitted to your car.

STEP 02

Exchange unit supplied

We supply an already reconditioned, bench-tested unit on exchange — your old unit becomes the core, refundable £250 deposit applies.

STEP 03

Fit & warranty

Fit it yourself, or we fit it at our Coventry workshop. Every unit is covered by a 12-month warranty.

No flat retail prices — specification varies by model and generation, so we quote based on your specific VIN.
