My GF got her car service Astra 1.7 CDTI at 91k miles and the air con wasnt working.
The dealer said it needed a re-fill as we thought and charged € 100 (Ireland) for the pleasure and now at 95k the Air Con has stopped working again.
I am entitled to go back and have the dealer fix this again without any cost to me.
PS Also asked them to fix the Rear Window Washer, I think it worked for two days and then stopped working again. Does anyone know how to properly clean the washer to get all the muck out of it so the water will flow properly onto the back windscreen.
