You can check for any fault codes with the pedals.
Press down acc and brake, put key in, turn onto second click, the one where all the lights come on, look at the spanner light, it will start flashing, if it flashes and doesnt stop there are no fault codes, if it flashes 10 times this means 0.
So for example I had a fault code a while ago which was 0141 to get that the spanner flashed ten times, then stopped for 2 sec, flashed once, stopped flashed four times, again stopped for another two seconds then flashed once again...
I got mine off my vectra by doing this
