    2 Faults Found:
    20169 - Exhaust Pressure Sensor 1 (G450)
    P0471 00 [096] - Implausible Signal
    Intermittent - Not Confirmed - Tested Since Memory Clear
    Freeze Frame:


    9764 - Exhaust Pressure Sensor 1 (G450)
    P0470 00 [032] - Malfunction
    Intermittent - Not Confirmed - Tested Since Memory

    This faults didn't appear before but now exist! Like you said before this sensor was faulty, but why didn't show before? I will call Audi tomorrow! They probably didn't check faults after they replaced cooler.

    I'm not 100% sure because it's a while since I looked at this stuff but ts possible that the G450 is the differential pressure sensor for the dpf and not the MAP sensor I mentioned earlier in the thread. The diff press sensor is an important one for DPF regens so would need looking at ASAP if it is. Is your oil level increasing do you know or have you checked?

    Might be time to consider trading the car in for another while you have no lights on the dash. Early A4 B8.5 adblue cars are not the most reliable as they age. Only I can do 90% of the jobs myself I'd have got rid of mine at this stage. Only today it threw up an engine light due to a dodgy glowplug or wiring.

    Regen is normal as well. Usually after 300 miles. Call them today and see.

    Going by past experiences of people that work regularly in dpf deletes / adblu deletes this particular generation of VW group engine do not take wheel to dpf / egr cooler deletes . Within a short space of time after delete the engines end up with bigger issues.
    The Adblu you can delete as long as you dont have the adblu system fault countdown to no restart on the dash but will you make it through mot after I dont know.

    Should I replace this G450 sensor? Is just one or two?

    Get the dealership to diagnose it . You've had a lot of work done in the area it could be a cracked vacuum hose, bad sensor , loose plug, damaged wire. Tell them you didnt have the problem before they worked on it and now you have . You know this because you did your vcds scans before and after.
