First of all thanks to all the people who have previously helped me on this site with my earlier posts.
So this is where i'm at:
Initially had a 2 amp earth which was draining my battery every night.
Tracked this down to the IBS lead on the battery negative lead.
I have spoke to dealers and they quoted £106.00 for the part and £150 to fit. This includes 2.5 hours labour which is down to the reprogramming.
Therefore firstly do i need a new lead(as the car is starting fine without it plugged in) and secondly do i need it reprogramming and what will happen if i fit it myself and it doesn't get reprogrammed?
Thanks once again
