Hi, Thanks for reading my big story 
I bought a 2007 Q7 about 6 months ago. Since the warranty was expiring soon, I checked it out at the dealer and he said that there was absolutely no problem with it. Then I bought an after market warranty. I am in Colorado where we had a few really cold nights in the last couple months. Problems started last month.
- Sometimes the hatch would not close unless I opened one of the front doors.
- Few days later, the MMI went blank(It would turn on, but off after couple seconds).
- Few days later the battery went dead and needed a jump start.
As the dealer suggested I replaced the battery, but after a week it went dead again. Then the dealer did a thorough diagnosis(2 hours @ $115/hr. sigh) and said the fibre optic loop was broken due to the amplifier. The estimate he gives me is $1500 ($900 for the bose amplifier). Now the warranty company is saying that amplifier is not covered.
How hard is it for me to replace the amplifier myself and how much would it cost? Is there anything else I can do besides spending $1.5K? I am not trusting the dealer's diagnosis because initially he said the battery was wrong, then said phone module, then said he would close the loop by using a repeater since i didnt need the expensive phone module, then said bad amplifier.
I am looking for ideas from you all. Please chip in. Appreciate all your help.
