Just purchased (from germany) a long expected astra coupe 2.2i , which btw i would recommend to anyone who's having second thoughts .
From what i've seen / tested and tech2 told me , there seems to be a problem with the alternator and idle control valve .
- The idle control valve is always fluctuating the revs now so i guess it has to be changed (please correct me if i'm wrong) .
- The alternator for this engine i heard that it's quite expensive , around 800 and 1000 euros ( please correct me if i'm wrong ).
Anyway , my question is can only the diodes be changed on this alternator or do i have to change the whole alternator ?
Sorry but i can't give you more info about alternator type as i don't have this info .
Apart from these two issues (which may or may not ruin me in terms of $ ) the car is perfect .
