    Can't be too sure about the camshaft advance. Perhaps a problem with the VVT servo?

    G28 speed sensor must be okay, otherwise the engine wouldn't run. Maybe an old code that hasn't been cleared.

    Don't worry about the alarm ones too much.

    I'd clear them, go for a drive and then re-check.

    Still got these faults

    Engine Speed Sensor (G28): Implausible Signal

    Camshaft A (Intake): Retard Setpoint not Reached (Over-Advanced)

    Are they related? Is the engine speed sensor something to do with the camshaft position sensor?

    Any idea how i get to it? Where it is and is it easy to change? DIY?

    Ive cleared them a few times and they keep coming back. Getting a stuttering at 6k rpm in every gear. Want to get it changed asap.

    Cheers

    Engine Speed Sensor is a fairly common fault, it's related to the crankshaft sensor I think. My A4 1.8T had the same problem where the car used to conk out randomly, until one day it just wouldn't start at all, it just kept turning over.

    It's fairly easy to change, it's just held in place by a large bolt and the electrical connection.

    Engine speed sensor circled in red on the lower front of the engine. Can be a fiddly one to get to. I found it easier to change mine from below.
    Its probably called an impulse sensor in vagcat. Its about £70. If its dodgy, then that might be the cause of your missfires, which may in turn be effecting the cam position sensor. Either that or you are a tooth out on the cambelt.

    Car cut out tonight right at a junction!! Just slowly died as i was pulling up to it, tired re-starting but no joy, took about 3 attempts, eventually got going but sounding really rough and lumpy, gave it a few revs and it was fine, just as normal all the way home, 2nd time its done this now but last time was ages ago. Could this be to do with the sensor?? Intermittent fault?

    thanks guys :thumbsup:

    That will definitely be because of the engine speed sensor. Am I right in thinking that your EPC light might have been on too?

    Source the part yourself from eBay USA (cheap as chips), and it's a fairly simple swap over. The part you need looks like this:

    Make sure it is compatible with the 1.8T engine, as there are a few others on the market.

    Thanks matey, just been scouring ebay actually and theres a few about, some not genuine ones.
    Didnt notice the EPC light on but i was more worried about getting the bloody thing going and moved out of the junction!!
    Looks an easy swap, seen some on the online VagCat too, would rather just buy a genuine one, i can get it at trade anyway.
    Are they all the same for the 1.8T As theres 4 different part numbers on VagCat

    Thanks for the help mate, much appreciated
