I recently had the dealership replace a fuel pump on my 2003 A4, about a month after just replacing a purge valve. The very next day I put in about 12 gallons of fuel and noticed my fuel gauge only went to about 1/4 tank full. I immediately called the dealership was told once I filled up full, the fuel sender should reset and take care of the issue, but it was now only showing 3/4 full. The dealership looked at the car for about 4 hours and could not find any clear problems with the install, then asked that I leave the car overnight so they get try some other things. A week goes by before dealership calls to inform me they have no idea what the problem is and that I would need to come pick the car up, then return it with a full tank so they can try something else.

It is another 3 weeks before they can even schedule the car back in. In this time I notice even more issues that I never experienced before the fuel pump was installed, all electrical. For example, the heat will turn on high, even when it shows it's in the off position. My sun roof will open all by itself. Then just last week, the electronic immobilizer icon will turn on for a few minutes then go off, followed by the heat turning on full blast.

The dealership has now had my car for another full week and just left me a message that they have no idea what is going on and the issues have not been resolved.

Any ideas what I should do next?
