hi, just bought my signum 1.9cdti 150 bhp 55plate new shape. a light on dash of picture of car with spanner has come on and puts me into limp mode. took it to local garage they plugged it in and got 4 faults(codes).
p0100 came up twice
said i would have to book car back in as he didnt have a clue which way to go thought it good be a bad earth on ecu ect and said he would have to trace.Can anyone give me any pointers in the right direction as just spent £400 on timing belt kit and 2 new front shocker springs and only bought car last week and beginning to wish i hadnt many thanks in advance.
