Limp mode

[The The]

Hi Chaps, I have a 2.0tdi (Pdi) and every time I go over 4000k rpm in the lower gears it goes into limp mode, its not very often I'm that high in the revs so its only occasional, its perfect again if I turn it off and back on, also there is never any fault codes show up so no help there. Anybody have anything I can try other than getting a recon turbo when it may not be that. Cheers.

Fault codes?, sounds like overboost issue.

Try some turbo cleaner such as archoil as it could clogged up turbo vanes.

Cheers, there is never any codes up before or after, how is Turbo cleaner applied? Is it added to the oil?

You add a full bottle to your fuel tank when next fill up.  Use code ARCH25 for 25% discount on check out.

sticky vanes - agreed probably overboost code with fault scan

 

also if all your power comes in a big block around the middle of the rev range so not a lot at the bottom or top probably turbo is about knackered.

 

one way to solve this though...stop going over 4k

Cheers for the info I've ordered a couple of bottles of the turbo cleaner worth a try, shame no fault codes ever show up to at least give me a clue.

''The good ones contain a blend of chemicals, some of which survive the combustion process and reach the turbo.''

 

some of which...I would expect that amount to be very low, seems like a push to market their product

 

I mean it's cheap enough to give it ago, I suppose, but if you're already hitting limp mode the damage has been built up for a while and been done, even taking the turbo off or cleaning properly in situ is only prolonging the inevitable.

Cheers it's always good to be optimistic, if the turbo needs replacing I can't complain, it's done 80k and hasn't needed any engine work in the 70k I've had it, just the front brake callipers have let me down.
