    turbo overboosting

    Audi a3 2.0 tdi has been going into limp mode now and then which won't let it go past 60 if I turn it off and start it straight up again it will be fine. I've had it plugged into a scanner and I said turbocharger overboosting is this likely to be a sensor ? Thanks

    It's likely to be the turbo starting to fail. You can get it replaced for roughly £500

    BKD engine turbos are all suspect, particularly at that mileage.

    I think you'll have to bite the bullet and go for a reconditioned replacement.

    I had one at 75k miles - £695 fitted and guaranteed for two years.

    I don't know whether anyone has had any experience with midland turbo but I spoke to them and they said they charge 185 pound + vat to recon it which includes changing bearings and seals and a relly good clean up. Is that the road to go down ? Or do you recommend and others ? Thanks

    Yeah but you have to appreciate changing to a hybrid means a potential new clutch and a remap. Which is another £1000 easy on top of the turbo. Easier/cheaper to just get a refurb if your not that bothered.

    The turbo is good enough for 230bhp with an S3 I/C & uprated injectors, but I'll come to that later in the year

    It will be the vanes sticking. You can get some stuff by a company called innotec which cleans out turbos pretty much still on the car. You do have to take of the inlet pipes but apart from that it seems pretty good.

    So do you think it would be as good as new if midland turbo recon it ? Will it damage the turbo if I carry on driving it ? Thanks for your help.

    It won't do any more harm to a knackered turbo but, if it blows, you could be looking at a new engine !

    This was my first port of call. I've spoke to many people over the past week regarding my issue, lots saying try innotec it's great, others saying its a waste of time! I have a 2000+ mile round trip to Austria pending in the next 2 weeks, and just couldn't drive that distance without knowing that everything was ok. So when replacing the turbo, makes sense to uprate it! I already have the TBE, just need to get S3 intercooler and uprated injectors later in the year to accompany it!

    Looking forward to the car driving nice across the continent!

    Hi,

    I have exactly the same problem on A3 2.0tdi Sportback.

    Ive come round to the fact its the turbo but only gone into Limp Mode twice on the motorway with Cruise Control on.

    Any suggestions for the best place to take the money guzzling beast in the North West, Bolton/Manchester area?

    FYI - I stupidly had the sensor replaced but this was no help.

    Which hybrid you got N8? Stage1 your current injectors are OK, Stage 2 youll need injectors. You need the S3 cooler either way and a wider necked downpipe/decat.

    Im doing mine very soon aswell

    i got 51 mpg but if your worried about mpg dont get a hybrid because you wont want to think about mpg just on how well your car goes and you will need a new clutch unless your dsg as they a are bit more hardy

    Hybrid of my Garrett, I'll be ok without the cooler and injectors for now, I already have a TBE.
