I have a 2007 Audi A4 2.0t. It has 140,000 miles on it. Recently the check engine light came on and displayed the codes below. I'm not very knowledgable on Audi vehicles and want to figure out where to start here.

If you have knowledge of what these codes may signify please let me know...

05491 left engine mount solenoid. N144 open circuit. P1573 no signal/ no communication

01090 evap emission control system small leak P0442 upper limit reached.

12555 Low pressure fuel regulation. Pressure outside specs. P310b no signal no communication intermittent.

01110 Evap system very small leak detected. P0456 upper limit reached.

Please help!

 

05491 is a broken engine mount that has separate. The is not really a critical thing but you need to replace it soon.

01090 Could just be a defective Purge Valve

12555 check the vacuum hose to the fuel pressure regulator. Check for any cracks in the rubber or plastic portion of the line.

01110 could be related to the Purge Valve.
