I just got it a month ago, and the non BMW dealer, I bought the X from, told me the electrical is not under waranty. I have a 90 day dealer waranty, and a 3yr parts waranty from a waranty company. I have an appointment to go in to the non BMW dealer on monday;based on the the phone conversation we had, he told me to search ebay for an amp

. I would go to the REAL dealer, where I have my 328I serviced, but I just shelled out $22,500 out right for the X, and I want the non BMW dealer to fix my X out of HIS pocket.
So I'd like to take the trunk apart and attempt a self fix or at least see what is what before the try and pull a fast one. Based on my issues is this an Amp problem? Can I do unplug replug type of thing?
