Im a snap-on dealer so no probs with diagnostics ;-) And i know plenty of mechanics. I try and learn as much as i can myself though. My dad drives nothing but bmw's and i grew up with them. I know now why my dad likes them so much...another bmw driver for life with me i think. The 5 series is just another game all together from any other cars ive driven. I found the 3 series to sharp with regards to the steering and the suspension to hard. The 5 series is just right. the satnav seems to work but from what ive read the tv needs updated to digital. Are those 50 quid jobs from ebay any good? I read you can get updates for the auto box....is that an ecu update?
