Mk 5 TDi 2.0 170 engine misfire
« on: April 17, 2026, 07:43:01 pm »
Hi Folks, hope its ok to post about the GT Sport diesel 170 hp variant?

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 / misfire (kangaroo) if the engine is revved above 2300 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 fairly certain its injector related and have put some additive in the tank but was also wondering if it could be a faulty injector loom as there was a recall when this model was first released around 2010 and that was because of a similar issue. 

I'm loathed to spend too much on the car as its barely worth £400 at WBAC but it did pass its MOT today after a front brake calipers and discs etc hence  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
