2001 Audi Allroad

2001 Audi Allroad Description

2001 Audi Allroad. 2.7 Low miles for how old it is. I have owned the car since 2002/03? The motor is good, turbos are fine. The car drives and runs great. The interior is in really good shape. The exterior has a few dings. See picture. Some rust on driver side door (also in picture). Here comes the bad news.It is showing to OBD codes. P0155 - o2 sensorBank 2. P0491 - Secondary air injection system. The air bag light on dash is also on.
The car has started doing something strange. If you drive the car for any length of time it starts, drives and runs fine. If you turn it off and waitan hour or so. It cranks but won't start. Like its not getting fuel. Once the car cools completely down, it starts right up. I drive it to work and home from work every day. I just can't drive it to lunch for example. I drive it to golf every Saturday as well. It has four hours during my roundto cool down so I have never had it not start. It is very consistent. I have brought it to the Audi dealer and they say it has nothing to do with the two codes I listed above so they cant figure it out. I think someone with some knowledge on Audi's would be able to fix it. I have looked at some Audi blogs and found some owners with the same symptoms. Fuel injector seals was there advise. That makes since. If the seals are not expanding and contracting with the rest of the car, air gets through and the car doesn't start. I do not have the time or talent to change them myself.I do have receipts from a certified Audi mechanic for anything that has ever been done on the car. All the gadgets and accessories that came with the car work fine and to the best of my knowledge everything I listed above is all that is wrong with it. If you are local come take a look.Thanks for looking.
