Frequently Asked Questions
Is this service compatible with all BENZ vehicles?
This service is specific to the W213 module. BENZ may use different module part numbers across their vehicle range, so it's essential to verify your exact part number matches before ordering.
What if my module has a different revision code?
Minor revision codes (like -A, -B, -01, -02 suffixes) are usually compatible. Send us a photo of your module label if you're unsure - we can confirm compatibility before you order.
How do I confirm this will fix my problem?
First, diagnose your vehicle with proper scan tools to confirm the fault is module-related. If you're seeing codes like P0A80, U0100 that persist after addressing physical faults, module service is likely needed.
Do you offer mobile service in my area?
No, this is a postal service only. However, many customers find it more convenient - you can remove the module yourself (usually straightforward with workshop manual), send it via Royal Mail, and have it back within 2-3 days total.
