Hi
My car is C4 Grand Picasso diesel auto 1.6 Hdi, 2009

After the garage (Mechanic) removed the battery and change gearbox mountings. (Engine managment system faulty) appeared in the dashboard. The garage tried many thing using the computer but it still did not go. The warning still their every time I turned on the car.

Any idea how to fix this? The car run okay and normally only this message (engine management system faulty)

You need to get the fault codes read but I suspect the wiring behind the battery might need checking

Thank you Rusky, I will ask the mechanic to do that but he said he removed he battery terminals and put it back again many time trying to fix this fault but it didn't work. I forget to mention that the message ( Engine management system faulty) came with 'Service' light that stick their as long as the car turning on.
