I'm interested however two questions
1. Does this affect the BMW 3 year warranty if something goes wrong with the engine?
2. Is this something you disclose to your insurer and if so how much does it add to the premium :(
Cheers Poolie!

I would be very surprised if the warranty isn't void and if you have an accident and haven't declared this modification your chances of being covered are reduced possibly to nil.

That said, the insurers are very unlikely to find out unless it's a very nasty accident - I have never heard of any insurer interrogating the car's software

Not sure how BMW would cope if they had to check every map on a car at a service interval, again if the turbo goes for example and BMW AG ask for more info you could well be stuck.

When you take it in for a service, BMW will upload their latest engine parameters which will probably overwrite your remap.....

Not very likely to be done during routine service, only if there is a specific recall or update (e.g. something like the VW emission cheat).

I'm on a couple of motorbike forums, and the discussion of remapping comes up regularly. I have had my bike done, and declared it to the insurers, and it made no difference to the premium.

If anyone gets a remap, make sure you tell your insurers, as I read of a case where a bike rider killed someone, the insurance company took the ECU apart and found that it had been remapped and the owner hadn't declared it.

The guy ended up losing everything, as he had to pay the family of the deceased, the uninsured damage to the bike and car that he hit, plus the associated fines.

He was particularly unlucky, as the person he killed was a high earner, so the judge made him pay an even bigger sum to the family, due to loss of future earnings.

Your car will be connected to BMW servers if it goes in, regardless as they update systems all the time.  They will find the remap as the checksum will change automatically every time a code is amended.  It takes a couple of seconds to spot things, and Owners on here have been caught out.  Unless your remapper can ensure that no checksums change then even a safety check (mine has one EVERY time it goes in) will pick it up.

If you are involved in any serious accident where a Police investigation is required, a check is run.  Data from the engine will be logged and checked.  The chance may be small, but the effect would be cancellation of insurance and you then get prosecuted for various serious driving offences and could lose your licence and liberty as well as the car.
