Slight hesitation, already had a coil pack changed, any ideas?!

    Hi all,

    After having my A3 remapped, it seemed to make a little hesitation more pronounced.

    The hesitation happens when you accelerate gently, for example on the way home from my g/f today i was going about 75 in 6th, and if i moved out to over take, put ur foot down a little, it goes instantly then i know its gonna hold back and then go. Its not turbo lag, if floor it, then it just goes.

    I had this a couple of months ago and my mate had it in as he works for VW and a coil pack had given up, he fitted a new one, it seemed better, but when funny again, i started using Shell Ultimate and it seemed better, but now its back to hesitating.

    I am not using the car an awful lot I must admit, in fact i am thinking of now selling it and going back to the dark side of oil burners!

    Any advice much apprecited

    Cheers

    Dave

    hello mate, it could be something to do with either n249 or n75 valves,although im not sure if your model has these.if its not working it seems to make the car hesitate under load, i had a similar problem on my cr so chhnged both of them and the dump valvand things are going fine.or check vagcom for diagnostics.

    ive got a price for the N75 valve, but do you know how much it would cost to replace the N249 valve as im getting faults on both :mad:

    id personally whip to a specialist, just gone through a process changing things and could have saved myself some money on my heavily depreciating brick

    I have been getting a very slight judder on acceleration so I guess it could a whole lot of things, not just the N249 or N75. Buggar.

    Vagcom it
    Check your boost and oil breather hoses for any leaks or splits.
    Give the TA a clean and a realignment
    Check your MAF
    Change the N75 and N249
    Pray

    The N249... is this the valve that sits ontop of the cam cover? towards the front? With a pipe from it going to the DV valve?
    I am sure i have read somewhere that some seat LCR owners have removed this valve alltogether... or am i very wrong?
    :uhm:

    I've been getting a nasty judder and loss of power when I put my foot down occasionally but It goes back to normal when I ease off the throttle. Doesn't do it all the time but seems like something is on its way out. Anyway, I Vag-Com'd it earlier. It threw up fault code 17608 - Boost pressure control valve (N249) mechanical malfunction. I guess I've found the problem. If this sounds familiar, then its probably this. Isn't Vag-Com wonderful!!

    i had the same fault as you and changed the n249 and i still had the same problem, and i was told this by audi. its going back into audi next week to get checked and sorted. the n75 can cause the same problem as the n249 so its a bit misleading, i think that will be the next move for audi to change my n75.

    Sorted it. It was the DV not the N249. Car pulls and sounds much better now. When the N249 valve fault was thrown up it did say at the end, "Check DV". It was right about that. Luckily I bought the DV first so didn't shell out on a N249 that wasn't needed.
