Just arrrived at the hotel in Penang Isle when my 528i became jerky. I think one of the ignition coils is faulty. Anyone can suggest a good independent mechanic with good diagnostic tool in Penang isle? I'd be here until Sunday. Appreciate if name, mobile number and address can be given so i can send my injured UDM for a treatment. Dont wanna drive her back to KL like that. My mobile is 012-3827078. TQ in advance.
