If your turbo(s) or gearbox were to blow whilst the car was under warranty i'd imagine BMW would take a dim view if the car had been remapped.
But everything else would be covered. Things i've had sorted under warranty on my last three cars have been - sat nav screen, various rattles, parking sensors, problem with stereo, alloy wheel corrosion (Schnitzers), all of which arent impacted by remapping.
I guess if you were really worried, DMS cover items invalidated because of a remap with their own warranty though.

I believe Mike at DMS said they have never had anyone with a problem so far, these tuners keep it well within spec so they don't get grief.
I know Ant from ant and pete were running a 330d E46 with around 100bhp increase and ran it for about a year on the standard gearbox and clutch with no problems, when they sold it they put a more docile map on for the new owner and he has run it for another couple of years with no problems.

drivetrain engine and gearbox invalidated confirmed by a BMW service manager, and yes tuning boxes taken off before service can be detected as well
Don't believe that this is true for all kind of piggybacks. Had mine in for the 20 tkm service and it hasen't been detected(box left on). The only thing they see is that the battery has been disconnected and a fault code from the active power steering. noneedtolift said:

Given that and you want to chip your new 330d worth £33k why not take your car to Kwikfit for them to service it? I mean youve ruined the warranty so what does it really matter - provided they adhere to the BMW service schedule then your fine.
+ any comments about wouldnt let those touch my car Ive seen young kids at BMW so no difference, one Merc mechanic stated that the engine was ruined on a Citroen AX after a 45min fiddle with it - turned out to be an air lock took a few mins to resolve. The brother of the Merc mechanic felt so much shame that he paid the girl back for his charges out of his own pocket , oh and the excuse... I work on the cylinder heads ... oh my Im not a qualified mechanic but I can sure as hell tell you if a car has an air lock or not..

Absolutely agree with you! My comment was simly refering to the statement regarding the detectability of piggyback ecu's!

Has it been tested?But if thats their warranty, i'd have no doubt they would honour it.

Im sorry but BMW or any other car maker is a business they state that any modification or infact using non geniune OEM parts invalidates your warranty. Its plain and simple.
Given that and you want to chip your new 330d worth £33k why not take your car to Kwikfit for them to service it? I mean youve ruined the warranty so what does it really matter - provided they adhere to the BMW service schedule then your fine.
Actually as long as you have your car serviced at a VAT-registered garage, using parts of 'equivalent form, fit and function' to BMW parts, the EU dictates that BMW cannot invalidate the warranty.Given that and you want to chip your new 330d worth £33k why not take your car to Kwikfit for them to service it?

I've had warranty work completed f.o.c. by a BMW dealer on a re-mapped car, they changed injectors first to cure the 'missing' fault, then the ECU itself, which sorted the issue.
I took the car straight back to the mapper (Superchips agent) for a f.o.c. map to be put back on the new ECU as it felt so painfully slow!

It invalidates your warranty.
However, the dealer does not pay for the warranty, so they're unlikely to refuse work seeing as it gets them money from BMW.
If BMW found out they would reject the claim. They could probably even reject a claim on your door handle, as modification probably invalidates the warranty full stop rather than just on "affected parts".
I'm not sure how BMW might find out though. For the poster above whose ECU was changed, then it is possible the ECU went back to the manufacturer/supplier for testing, in which case they'd almost certainly know it had been toyed with.
Data from the ECU is also automatically stored when the car is plugged in, and anyone can look at it, so they may be able to tell from that too.
