My car is at Audi now , I've never used this dealer. I got complete inspection and diagnostics for $100 at the other Audi dealer a hour away. This one quotes me $228 for each complaint they check. $228 yo check the creaking sound in front. $228 to check why it's overheating. $228 to check high revving thing it's doing. Is it just me or is that the most ridiculous thing you've ever heard ? I feel like I'm getting jacked.
2009 Audi A4 Quattro 2.0L TFSI
Had oil leak from rear main seal area and CEL lights on. Diag codes pointed me to replacing the PCV valve and I also replaced all 4 coils andspark plugs, air filter and cleaned mass air flow sensor. Also changed oil and oil filter. Since replacing PCV valve the oil leak appears to have stopped with a few days of the oil that had turbo blowby finally draining out.
Diag codes had dropped from 22 to just 4 codes left. P1287 (too lean / vacuum leak) and P0300-0303 misfires on all 4 cylinders. The car was running fine but a but rough at idle. Attributed to too lean mixture. Reset systems with battery unhook and touching positive to ground and then after hooking back up did a throttle alignment. CEL was still on but car drove fine, no rough idle, perfectly normal driving. Would even say it was driving as well as day 1 with turbo power and smoothness. No noticeable misfires. Just the CEL with P2187 and the 300-303 misfires still lit up. Over past week the following codes have crept into the equation.
So now I've got codes regarding fuel press or sensor, air intake leak, vacuum leaks, and cylinder misfires.
Now if I clear the CEL. The car runs rough at idle, in park, drive, whatever.. at idle it's rough and misfiring like it wants to stall. When the CEL comes back on after a short amount of time the car returns to driving normally. So I feel like the ECU must be compensating for something and normalizing the car properly. At this point I'm stuck on what to do next. Should I change the fuel pressure sensor? Smoke thevacuum hoses? Or just continue to drive it as is with CEL on for next year and a half until I get the amount owned left on the finance of the vehicle to get rid of it without getting killed financially. I have a mechanic friend who is helping me out with troubleshooting and I cannot afford to take this to a dealership for repair, but I feel like we are close to getting this squared away and just need to either fix a hose or replace a sensor and we will be home. Any thoughts or opinions would be greatly appreciated.
Sometimes when I lock with fob it locks but no beep sounds. Then when I unlock the passenger door won't unlock. Or all will unlock but driver side. It's very random. Sometimes it works sometimes it doesn't. What is the problem and can I fix it myself? Seems like an electrical issue or fuse ...... Please help
Began suddenly after getting on highway. Then continued on the drive home with acceleration. I've read it could be the speed sensor. If so how much might this cost to fix?
I am replacing brake pads and rotors. Thought the pads came with the sensor(s) and need to know if I should order one sensor or two.
According to the dealership the front brake pads are completely worn. They want to replace the rotors at the same time. This seems excessive, particularly given the low mileage.

I have a strange circular clip retaining the base metal of the existing lamp bulb. Not like all the other spring clamps of past. How do I get the thing off and on so I can change out headlamp bulbs?
The 2nd day I owned the car, the epc warning flashed along with the engine speed limitation. The next day it was the battery in remote control key. The warnings are coming on during regular driving. The dealer said not to worry that it is nothing, but I'm concerned that this could be an ongoing issue with the car. Any thoughts?
Where is the oil dip stick located in engine compartment? I looked at the manual & it is not where it shows it to be.
front passanger auto adjusting headrest needs to be removed on my 2009 A4 Quatro. How does the headrest release for removal
How do you change the oil filter on this vehicle? Where is it located on the engine? It is a turbo if that makes a difference.
