Had the car in at my (not so) local BMW dealer for some work this week. Part of that was updating the software in my transmission. Anyhow, I get the car delivered back, to find that not only had they wiped out my (paid for) Car and Key memory settings, but had also wiped out my Voice Recognition and TV in motion codings - in fact, everything I had coded with NavCoder.
Had a rant at the Service Manager, who smugly tells me that they don't bother to read the vehicle before making coding changes, and it's not their fault if 'unapproved' changes have been made to the software

In fact, he was trying to claim that it was these changes that caused the problem and because of these 'unapproved' changes my warranty was likely to be void. He obviously doesn't know his consumer law
So I am back to having to drive 60 miles to book my car in for the car and key codings to be reset - luckily my SES and TVIM settings I did myself in about 5 minutes. Roll on NavCoder being able to code Car and Key Memory too (please Jochen!!)
So be warned. If you take your Navcoder modified car in to be 'adjusted', make sure they know that these changes are active.
