| Sorry to hear about your problems!
I have had a 75bhp up to 50k and am in a 88bhp with 47k on the clock and never had a problem with the battery. Both cars have been left for over 2 weeks while we have been away and both started without a flinch upon return.
Might be worth getting the dealer to do a voltage check to see ing is draining it accidently, I have read about something similar on another thread somewhere. Will try to findit if I can.
Hope you get it sorted soon though. |
