Shifting into 1st gear from neutral is difficult sometimes. Shifting into 2nd and then into 1st makes the problem a little better. Shifting into 3rd is also sometimes difficult. When starting the car in the morning after sitting all night the engine surges for about 10 – 15 seconds. Twice I have experienced engine surging (rapid RPM increase) without pressing the accelerator. Once while in gear and once while shifting gears. The bolster on the left side of the drivers side seat is starting to crack after only 15,000 miles. The passenger side rear view mirror does not return from curb view after taking the transmission out of reverse. The RNS-E satellite navigation systems sometimes fails to read the map DVD after the unit has been operating for some time and the car is turned off and restarted. Automatic windshield wiper control occasionally starts wiper when the weather and windshield are dry. When using auto close the passenger front window closes and then re-opens partially. Reset the Time/Distance to next service display. Check Engine Light came on. Code P2097 - Post Catalyst Fuel Trim Too Rich Bank 1. Dealer replaced O2 Sensor.

Rear window glass continued to separate from canvas top letting water into car. Noticed was still a problem when heard water sloshing under floor when going around corners - water had leaked behind rear seat into space under rear seat footwells. Dense foam in flooring soaked it up until it sloshed. Used 3M Black Window-Weld around all edges of window and forced into into any areas that separated. Applied pressure with weights to maintain window/fabric contact for 24 hours to set up. No More leaking. Had to pull up carpets and squeezed at least 2 gallons of water out of foam under floors, and kept in the sunlight every day for a week or so to dry it all out. Convertible top failed. Previous repair included resetting brushes on electric motor attached to hydraulic pump, but that did not work this time. Bought a new electric top pump motor from Audi dealership and self-installed. Worked immediately. Took about 3 hours total to remove all trim to get at motor, take out motor, replace, and put trim back in place.

I started the car the next morning and there was no low oil pressure warning but the engine still sounded rattly and the check engine light was still on. I called for a flatbed to get it to my mechanic but due to a snowstorm the truck took 4 hours to arrive and when I started the car to move it out of my driveway the problem was gone, no engine rattle. I still had it taken to the garage but aside from resetting the CEL they could not find any problem. It had been quite cold (-20C) so they think that had something to do with it. I always run synthetic oil so it shouldn't have been an oil flow problem. They don't think it was actually low oil pressure as the CEL was unrelated but the engine noise to me seemed to point to it.

Replaced passenger side XENON HID BULB of type D1S. Bought for $99.99 @ Canadian Tire. Because low-beam was burnt out. Original said "Philips". Replacement came in a Sylvania box, but lamp is OSRAM. Is so identical to Philips that I'm sure that both came out of the same factory. The window regulator was shot, as indicated by "crunchy sounds" when operating the power window. rnThe regulator for the Audi includes the entire window frame, mechanism, stainless-steel cables, and plastic pulleys. rnThe parts are pricey (CAD$341 from Audi -- there are no cheap Chinese knock-offs) but labour is very low, because its all one, pre-assembled unit. rnKelly and team at Sun Creek did it for around $400 plus tax. rnAt an Audi dealership it would have been double that price.

Replace fuel filter and fuel pump. Fuel filter had never been changed, after changing a CEL came on for too low of duty cycle on fuel pump. It was only because of the filter change, but researched it more and found out how to read the duty cycle in VAGCOM and it was actually reading around 76% at idle. Deciding to preventatively change the pump although it appeared to work fine. New fuel pump is around 50%. I believe the pump had premature wear due to the fuel filter never being changed.
