There is a problem though. Due to the fact the the chip is located with the ecm box, they can say that even opening that box can make your wiper motor blow. QUOTE]
Most, if not all chips now are reflashes, they dont require any physical access to the ECU.
Even so, my VW dealer has replaced the turbo on my TDI no questions asked, even though it is and has been chipped since new, and a hard chip, not an ECU reflash.
To clarify anyway, the turbo blew because about a year prior to it happeneing, I was involved in an accident that looked purely cosmetic, but it starved the turbo of oil for about 5 minutes of use.
