Question 1

What does fault code B2AAA mean on my car?

Accepted Answer

B2AAA is a manufacturer-specific code indicating a fault within the Body Control Module (BCM) — the central electronic unit that manages wipers, lights, locks, windows and other body systems. It means the BCM has detected an internal error or a communication failure with the systems it controls.

Question 2

How much does B2AAA BCM fault repair cost in Wood Green?

Accepted Answer

Diagnosis at MnF Motors starts from around £65–£85 for a full electrical system interrogation. Depending on whether the BCM needs configuration, repair or cloning, total costs typically range from £150 to £450. We give you a fixed quote before any work begins — no surprises.

Question 3

Can I drive my car with a B2AAA fault code?

Accepted Answer

In many cases yes, but it is not advisable long-term. Symptoms such as wipers activating randomly, central locking failing or lights misbehaving can become a safety or MOT issue. We recommend booking a diagnostic check as soon as possible.

Question 4

Do I need a new BCM or can mine be repaired?

Accepted Answer

Many BCMs can be repaired or cloned rather than replaced outright, saving you significant cost. At MnF Motors we diagnose first to determine whether repair, recoding or a replacement unit is the most cost-effective and reliable solution for your specific vehicle.
