NEW 535D M SPORT
Discussion
The good quality 'chips' are fairly well undetectable during routine servicing work. However should your car develop an engine fault the dealer will probably notice that some of the DDEs (engine ECU) identification, basic and programmed part numbers will have been deleted or replaced with 00000000 etc.
I've seen this on a 120d, and dependant on dealer they may refuse to carry out any work under warranty.
Can't gaurantee that this is true for all chips though.
