Question 1

What does the B2AAA fault code mean on my car?

Accepted Answer

B2AAA is a manufacturer-specific fault code pointing to a communication or internal failure within the Body Control Module (BCM). The BCM is a central computer that manages your wipers, lights, door locks, windows and more — so when it faults, those systems behave randomly or stop working altogether.

Question 2

How much does BCM diagnosis cost in Enfield?

Accepted Answer

At MnF Motors we charge a transparent diagnostic fee to pinpoint the exact cause of your B2AAA code before any repair is recommended. Call us on 020 8803 1231 for a current price — we do not quote online because diagnosis complexity varies by vehicle make and model.

Question 3

Can a BCM be repaired or does it need replacing?

Accepted Answer

Many BCMs can be repaired or cloned rather than replaced outright — saving you significant cost. MnF Motors assesses each unit individually. Where repair is not viable, we source and program a replacement unit. We never recommend a new part unless diagnosis proves it necessary.

Question 4

Is it safe to drive with a B2AAA fault code?

Accepted Answer

It depends on which systems are affected. If your wipers, lights or power steering (on electrically assisted systems) are behaving erratically, the vehicle may not be safe to drive. We recommend booking a diagnosis as soon as possible. Call MnF Motors on 020 8803 1231 if you are unsure.

Question 5

Do MnF Motors cover Enfield for BCM fault repair?

Accepted Answer

Yes. We serve Enfield and the entire surrounding area within 20 miles of our Edmonton N18 workshop. Enfield customers typically reach us in under 15 minutes. For complex module work we also accept vehicles by arrangement from further afield across the UK.
