Hi everyone, I have an audi a3 8p 1.6 with the BGU engine code. I have posted about this before but I cant find the original post.
The issue itself is that the car at times has a bouncing idle, in the past it has stalled out (total 4 times this has happened on different occasions). I have a few videos so I will get them uploaded on some vid to url site on what it does to give you a better idea. So far I have cleaned the throttle body, map sensor, replaced my rad fan assembly (due to it not working). In terms of codes I remember something to do with a lean bank 1 code at some point but I cleared it and haven't seen it again. I have also had another code that said something like idle higher than expected intermittent air something but i can't exactly remember. I have heard this is due to the block breather which is the thing under the engine oil cap, I have no idea how to replace this but I have found the part for £15 and I would appreciate if I could get some feedback on what I should do. I did remove the oil cap while car is on and its easy to take off and revs don't change at all. I have got the common symptoms for it I guess (unstable idle, oil seeming to disappear although the car is parked up and a lot of water out the exhaust). I am unsure what this means.
If any more details are needed I am happy to provide them and videos. I am trying to get the car sold by the weekend as someone wants it for then and I want give them a good car which doesn't have any issues.
