    Laggy response when releasing throttle 2.0T CCZ engine

    Hi,

    I'm happy to post my question here (or have it moved):

    I've just bought a cable to help me workout what is going on with my car. Three dealers are using the 'it's normal' canned response but when I compare to my friends same make and model, it isn't behaving the same way.

    The Car:
    10/2012 VW Golf GTI Mark 6 - Manual and leather are the only options
    40,000km - I believe it has been doing this for the last 10,000 or so.

    Behavioural issue:

    Driving along cruising with rpm around 2500 and light throttle application. Once I remove the throttle the car continues to maintain current speed for approximately two seconds before engine braking occurs. This is evident by:
    (a) the engine note doesn't change after lifting off the throttle. It only changes after two seconds
    (b) the recommend gear that is displayed in the top right hand corner of the central DIN is still telling me to upshift. Once engine braking is occuring the suggested gear then changes to indicate the current gear that you're in.
    (c) you cannot feel the car slowing down for the first two seconds of being off the throttle
    (d) whilst engine compression braking (actual) a slight touch of the throttle (a mere blip) equals the car to do the whole maintain current rpm for two second before compression braking again
    (e) as a test I was driving along and pulled the car out of gear (no clutch) and lifted off the throttle and sure enough (as you can see in the you tube video) the rpm holds high for around two seconds before dropping back down to idle.

    I've completed an initial scan - the results are below:

    I've also spent a few minute monitoring lambda. What was noted is the sensor was reading 0.9ish while on light throttle. As soon as I lifted off the throttle the value changed to around 1.02 for the two seconds after lifting off throttle before changing to 1.999 once engine compression braking started occurring. I read that as the car is still fuelling even though I am off the throttle

    My question is -
    How do I use VAG-COM to capture the data I need to show what is going on isn't normal
    Or can I clear out all the 'learning' the car has done and return it as if it is factory fresh

    Measuring Block Group 062 might be interesting. It will show you both pedal position sensors and both throttle position sensors.

    As for getting verified, please see this post:

    I suspect the the paragraph labelled 2) applies in this case.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Yes - Re-seller in Australia. Ok I'll sort that out.

    With regards to measuring block group 062 - would there be anything else worth logging at the same time?

    Primarily RPM.

    -Uwe-

    PS: I'm going to change the title of this thread to something more descriptive...

    Uwe - Thank you.

    What I've monitored thus far is throttle position (Group 62) and watched Sensor 2 (G185) which shows a value of 7.4% when I am not touching the pedal. While driving I can see that as soon as I lift off the throttle, that value instantly returns to 7.4%

    I've also monitored group 31 in partucluar Lambda control Bank 1 (actual)

    What I've noticed is that Lambda control bank 1 (actual) shows a value of 1.99 when actual compression braking occurs. I assume it relates to the percentage of oxygen in the exhaust. IE no fuel being delivered, so increase in oxygen going pass the lambda.

    So in monitoring this I can see that there is a delay in closing the thotttle . And there is.

    There are occasions where the car does behave itself. I am yet to capture that in the data.

    Here is an example of releasing the throttle and response is instant.

    I'm sorry for the three posts in a row but wanted to separate out what I can see.

    The above two posts have logs from separate runs/logging. I am assuming the time stamp is in seconds.

    When there is laggy response in closing the throttle
    The time stamp from when I close the throttle is: 125.78
    The time stamp from when lambda sensor registers 1.99 is: 128.36

    2.5 second delay

    When there isn't a lag closing the throttle
    Time stamp when throttle is closed : 45.95
    Time stamp when lambda is 1.99 : 46.86

    less than a one second delay.

    So - The car is still under warranty. It's been to several dealers all saying it is fine. How do I convince them that it isn't, and what should they look for.

    Yeah, I see the throttle valve following the throttle pedal fairly well, but the lambda not, but I don't have an immediate theory why.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Thank you. Let me know if you want me to monitor any other groups and go for a drive....

    Uwe - have you had any thoughts on what this could possibly be? Should I do any other logging of any particular groups? Injectors? fuel pump?

    Not sure if it is related - but I also feel that shifting between gears (it is a manual gearbox) that revs can often hang as well. A few occasions when in neutral and at an intersection I'll blip the throttle and the revs will climb to around 2000rpm - hang for a while (not as long) before coming back down.

    Finally - I'm finding the oil temp (as my centre console shows it) is anywhere from 109c to 123c (as I saw on the weekend during a long drive)

    THank you for taking the time to help me.
