Approved Used 335d found to have been mapped

[Pferdestarke]

A friend's E92 335d has been in to a dealership recently for a turbo-related failure (not the turbo specifically but a related mechanical part)

He got a call from the dealership where it's being repaired stating that the car has been re-mapped and it shows on their diagnostic machine. He wasn't made aware of this by the dealership at the time of purchase and has insured the vehicle as a standard car. It absolutely wasn't re-mapped by him.

He purchased it last November at 49k miles and has added another 16k in that time. It was an Approved Used from a recognised franchise and is covered with a full 12 month warranty as you'd expect.

How would you suggest is the best way to deal with such a situation?

Apparently the BMW diagnostic machine won't offer date/time stamp for when the vehicle was mapped.

As has been mentioned earlier in this thread, my friend really needs to find out if this is information is available - whether
It be through BMW or an independent expert.

Can anyone offer any advice here or recommend anyone in the Yorkshire area?

What are he symptoms of he turbo 'related' failure ?

No boost.

They've replaced quite a few components and it's now fine.

He's speaking with the supplying dealership regarding warranty extension and possible gesture.

T, give Tim a call at Auto Technics 01302 761919. He will give you some good advice on what your friends options are, explain that I put you onto him. You have met previously.

Cheers S. I'll give him the option of calling for advice. It appears quite difficult to prove when exactly the map was written to the ECU.

Worth a chat I'm sure.
