Hi Ben, I have just picked up my 2009 135i. Dealer tried to sell me one, got two years thrown in. Spoke to indi BMW specialist about remap and mentioned the cover. They can get funny about claims, want to send their own techi to look over car first. Make sure u keep the car serviced via vat regd garage or could void. Make sure they use genuine parts or could be void. Ultimately they will try and wiggle out of coughing up...
