Recently my Astra 1.7DTi Mk4 has been displaying the ‘spanner’ symbol on the dash. The spanner symbol only seems to come on when the engine has been running for a few minutes, and sometimes it doesn’t come on at all. The performance of the car seems fine (to me). I’m still getting 45mpg urban and there are no ‘performance’ issues as far as I can tell.
So I did the ‘pedal test’ the other day. Turned the key 2 notches and kept my feet on the gas and brake to read all the codes.
I also filmed the flashes with my mobile to double check the codes.
After turning the key the spanner symbol displays constant…it then flashes as follows…
Using my laymans knowledge I’m interpreting these flashes as the following codes:
1105, 0370, 0571
Can anyone advise on what may be wrong with the car and the next step(s) I should take?
