Common Faults:

Vauxhall Meriva engine management ECU malfunction is extremely common due to internal component breakdown. This will cause the vehicle to drop into a limp home mode state, cut out randomly, usually when hot, and fail to restart until cooled down. The EML (engine management light) will stay illuminated and fault codes will be stored for: P0230 - fuel pump relay, P1120 - accelerator pedal position sensor 1 low input, P1122 - accelerator pedal position sensor 2 low input, P0340 - camshaft position sensor circuit malfunction, P1550 - electronic throttle control limp home limited performance and P1483 - fan control 3 open circuit. On occasion the internal malfunction will prevent this ECU from establishing communications to diagnostic readers. Our comprehensive test and rebuild service will resolve these, and other, issues.

Meriva ecu...working again ! 5/5

I had my meriva ecu repaired ( it had the typical overheated issue as its bolted to the engine. ECU Testing stood out from the crowd when i started to look around due to there knowledge of the common issues and the customer service..evident from other reviews. Sent mine off on a saturday...had it back for the following saturday and that included a bank holiday. They keep you updated by text/web and very helpfull on the phone. Cant fault them.

Excellent service 5/5
