DIAGNOSIS

Signs your alternator is failing

01

Dimming or flickering headlights

The most common early sign - the alternator is no longer keeping up with electrical demand.

02

Battery warning light on the dash

Not about the battery itself - it means the charging system voltage has dropped out of range.

03

Whining or grinding noise

Often a worn bearing inside the alternator rather than the drive belt.

04

Flat battery despite a recent replacement

If a new battery goes flat again quickly, the alternator usually isn't charging it properly.

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 alternator fitted to your car.

STEP 02

Exchange unit supplied

We supply an already reconditioned, bench-tested alternator on exchange - your old unit becomes the core, refundable 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 engine and model year, so we quote based on your specific VIN.
FAQ

Mercedes-Benz alternator questions

Which Mercedes-Benz models does this fit?

Our Mercedes-Benz alternator stock covers Sprinter, Vito, Viano, C-Class and E-Class - the exact unit depends on your specific engine and model year, which we confirm from your VIN.

What are the symptoms of a failing alternator?

The most common early sign - the alternator is no longer keeping up with electrical demand. Not about the battery itself - it means the charging system voltage has dropped out of range.

Can you quote a price from my registration number?

No - the same Mercedes-Benz model can use several different alternator variants across its production run. We quote from your 17-digit VIN, which confirms the exact unit fitted.
