My Cube had suffered rear bumper damage. Its been in body repair shop for 3 weeks. came to collect it today. They said the engine management warning light has come on and it will not rev above 2,000. I told them this is the first time it had happened. They got Auto electrician in and he came up with fault codes U1001, U100, P1123. He cleared all the codes and it was running ok. I came to collect it and the engine management warning light has come back on and will not rev above 2,000. The repair shop are going to get the electrictian to come back in the morning and see if he can sort it it out. Has anybody experienced this problem.
