Been having a starting issue with my A5 that is getting constantly worse. Hoping someone can lead me into the right direction.
Car details:
2012 Audi A5 with 42,000 miles. 6 speed manual. Zero modifications. No Check engine lights or other error lights after startup.
Problem(s):
About two months ago my car wouldn't want to start. Press the clutch, gauges sweep, but nothing after that. Would try again and then would start. As time passed I had to attempt to start it a few times before it would attempt to start. Fast forward to now the car almost always does not want to start. Sometimes it will and then shut off after 2-3 seconds. Then it won't want to start again after a few tries. Once the car actually starts and runs past a few seconds it will run perfectly normal. Today while dealing with this I started getting more faults with TPMS, air bags, and power windows wouldn't work but all that went away once the car did turn over properly.
Press clutch, push key, gauges/needles sweep:
- Starter does not engage. Nothing happens. Silent. Stabilization fault appears.
- Starter engages, car starts, shuts off after 2-3 seconds. Stabilization fault appears, TPMS lights up, Headlight sensor error, eBrake error.
- Starter engages, car stars, shuts off immediately. Stabilization fault, TPMS lights up, Headlight sensor error, eBrake error.
- Starter engages, car starts and runs perfectly normal. All electronics work and errors are gone.
Did some research on here for a few days and the only thing I can somewhat come up with is the clutch switch which is also integrated into the clutch master cylinder. Seems odd that it would cause all these other issues as well. I did a scan with the Carista app and came up with these soft codes I'll post in my next post below.
