I have a 2007 Q7 we purchased as Certified 3 years ago. Since the extended warranty ran out in Nov it's had 2 service issues - oil baffle and hose replacement - each at $500 avg for the repairs. Now the climate control has no power and keeps tripping new fuses. A free diagnostic at local euro shop thinks there is something blocking the air intake that is causing the system to draw too much power. Estimating 5 hours to further diagnose and repair $500+ and now the check engine like back on, scan indicates another electrical issue. I love my Q7 but at 95,000 miles and a trade in value of around 17-18K - this girl doesn't know if its worth it to continue to fix. All positive and helpful advice would be appreciated. Thanks
