    Issue with the 2007 Audi A4's 3.2L V6 cold start.

    You need a VCDS scan too see what the MAF is saying and also O2 sensors and what cylinder the misfires are coming from. Try unplugging your MAF sensor first it could be sending dodgy info to ECU. If no change then do the thing below. stand at the back of the car when starting it and see wait...

    3.0 v6 (ASN) P0421 Cat B1 below threshold

    My initial thoughts last Month when it first started was the B1 pre cat sensor but because it is acting the same as the B2 pre cat sensor (where there isn't a problem) I dismissed it. I have managed to buy a new bosch pre cat sensor and the other option after reading up is to check the exit of...

    3.0 v6 (ASN) P0421 Cat B1 below threshold

    That is exactly what i have done, although my results in regards to emissions are sligtly lower in 60’s instead of 90’s. I got cat 1 not ok also, then MOT passes with <.30% = 0.01 emissions. Only thing I can think of is that he measured it against a very high threshold limit.

    3.0 v6 (ASN) P0421 Cat B1 below threshold

    Thanks Callum, the fuel trim on both banks is between -1 and -2 which in my mind says there isnt any extra air getting in (manifold or otherwise) even if there was the cat should still deal with it.

    oil light on

    I also have 3.0 V6 and had YELLOW oil level fault, RED is the more serious oil pressure. Mine usually came up after 50 miles, if you know your oil is fine open the bonnet and close it and it goes away as it assumes you have put more oil in. Mine was at 80k when it became dodgy I replaced it and...

    Couple of Sat Nav questions

    Probably not best practice to be looking down that low whilst driving. Cheapest option would be to use your phone if you are wanting audio guidance seeing as its already kicking out sound through bluetooth.

    You need to stick it on vcds and have a look on steering module it will tell the angle what it thinks the steering wheel is, make sure its straight. Depending on what it thinks the angle is a slight turn of the wheel will make it think you are throwing it around corners and activate ESP...

    This is where it starts to get messy in my head, when you say you have the 8E0953549N steering module that is for cruise and old skool multifunction (b6) check link below. The functions on your new wheel I would of thought would require 8E0953549Q or R (B7). If you do need that module you...
