This is a 2011 Q5 2.0T.. Only had 2500 miles on the oil change and the Indicator light came on but the MMI showed it had oil. Then the oil pressure light comes on. I stop turn the engine off then turn back on and the low oil pressure light went off but the indicator light stayed on. I got the oil changed and drove it for about 25 miles and the low oil pressure light comes on again and then stays off after starting it again. Please can someone tell me what's going on???? This vehicle is driving me crazy :-( not to mention it uses more oil than fuel!!! The oil consumption test was done on it 2 years ago but it never stopped uses tons of oil and I can't get any help from my dealership...

I wouldn't drive it with a low oil pressure light on. You need to have it checked by a shop or the dealership.

Same thing happened on my 2012 Q5 2.0t. Fixed by replacing the busted PCV. That part has been revised by Audi so there's a newer part number than what was originally installed.

Find another dealer and have your pistons replaced. Tensioner + chain while the engine's out as well.

Contact AoA.

Changing your oil will not affect your oil pressure at all.

Let AoA know this is a documented issue that has been going on for a long time and that your dealer is clueless, let them send you to one that has a better grasp of the issues.

Driving with a low oil pressure warning is a good way to scrap down an engine, and then it becomes totally your fault for ignoring the warning.

Sometimes the pressure sender is faulty, so the warning is bogus. Sometimes the oil pressure regulator or pump is defective. These are all things any idiot in the service department can check and correct.

I'll add to my unique issue. I had a MIL for low oil pressure and lean bank #1. Also, I was unable to remove my oil cap while the engine was running, which isn't a bad thing to check. My old PCV part# was 06H103495J and the newer revision is 06H103495AE. Your issue may be different and worse but this is what happened to me, out of the warranty period.

I too got this indicator light on. It is 2914 model and I did recently 45k servicing. Buying Audi should give consumers confidence, but these kind of issues within 4 years is really bad. Is there a extension warranty I can buy?
