    RS2 Down on Power

    Hmm, the RS2 isn’t behaving as an RS2 should. Got her booked into the garage for a check up in a couple of weeks time. But in the meantime - grateful for any suggestions as to what the problem(s) might be.

    Don’t seem to be getting the massive kick and surge in power as the turbo kicks in first at 3,500 rpm, progress seems much more linear than normal. Also definitely down on power – still quick but rather gutless. Seems to be operating at higher revs for the road speed – ie normally expect to be at around 3,000 rpm at 80 miles an hour in sixth gear but closer to 3,500 revs at the moment.

    There has been an intermittent problem for some time. Serviced and MOT’d in June and garage could find nothing wrong and typically operating OK when I took her to the garage. But problem returned.

    Two or three weeks ago, him indoors took her for a good blast up the motorway and coming home, suddenly the turbo kick seemed to have returned to normal and the grin factor was back. But it didn’t last for more than a few days and we now seem to be down on power all the time and the turbo doesn’t have the same impact. Also the power seems to come in surges, and then hesitates – doesn’t matter whether the car is hot or cold.

    Also on a few occasions, when pulling away from stationery, I’ve had to use more revs to get away and have stalled the car on a couple of occasions. Again – not normal behaviour for the car.

    Car has done 141,100 miles.

    Any ideas?

    Check/replace/clean
    MAF
    DV
    N75
    Boost leak

    These are all worth doing prior to blaming the turbo which seems still to work on occasion. I am sure you will get lots of more technical advice with a detailed story like that, but thats what I would do with the help of my local specialist initially.
    My money is on the DV if its not being changed as I had similar but less severe problems during the first few weeks with mine.
    Good luck

      Thanks for this.

      Had a problem with the turbo not kicking in properly last year and garage found a small hole in the intercooler, which was filled as an interim measure. Car fine for quite some time after that. But the power coming in surges, and general feeling of being down on power lower down rev range too, is a new symptom.
