Hi Folks,

I have a trusty Mk5 VW 170 Tdi Sport that has covered a largely very uneventful 229k miles due to regular oil changes every 5k miles. Unfortunately the car has started to cut out (kangaroo) if the engine is revved above 2800 RPM approximately hence i'm wondering what the common cause may be,

Its not a blocked DPF as that was removed some 100k back, the fuel filter was replaced about 30k back and there aren't any fault codes.

I'm loathed to spend too much on the car as its barely worth £400 at WBAC but wondering if this is fuel related as opposed to turbo as it doesn't seem to be over boosting and cutting out either.

I probably need to get a VCDS scan done and i'm based in Gosport PO12 if any one is available locally.

TIA

Sounds a bit boosty related, I would see if it has any codes. May be worth doing a visual of any boost hoses etc.

Many thanks its not over boosting and cutting out the fuel as far as i know. I've done a code read and there isn't anything coming up hence why i think its related to the injection system. I'm going to let the fuel level drop and then run a can of injection cleaner through the tank and might change the fuel filter also as a precaution. The car has done 230k miles and sadly nothing lasts forever

May not be the same but my Son has a Golf 1.4 petrol which had a similar problem, wouldn't rev above a certain amount.

Turned out to be a faulty accelerator pedal which was an easy (if not particularly cheap) fix.

Hi Thanks for the reply.

My diesel basically has such a bad misfire that it won't allow the car to rev more than 2200 rpm as above that it starts to misfire. From the research i've done and also the invites i've had to simply keep throwing money at a £400 car until it fixed i've opted to change the wiring loom to the injectors first as this was a part subject to a recall when these cars were first produced and if i pay the extra £15 for a rocker cover gasket it might fix the oil leak at the same time as that sounds a reasonable gamble for £60 of parts compared to a £2k bill from a garage that might still not resolve the issue.

Will update later this month on the progress to keep my £400 from the scrap heap that Racheal from accounts would rather see it end up on !
