How to Guides / Troubleshooting / Mk 5 TDi 2.0 170 engine misfire

« Last post by Rossco196x 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

There will be once you have removed the parts that have to come off like the driveshafts (strut can be worked around, battery off with mounts) etc

Highly recommend an engine mount as it will need to be lowered and tilted a little to twist slide the box off........getting the box back on was the hardest

So i traded my car in but removed a few things.
Bottle opener divider, ABR bushes, solid rear discs, window shades, dv valve and adapter to make vent to atmosphere, rear under chair led loom, kenwood DVB-T system, OEM number plate lights, used osram h15 bulbs, those weird push on plastic trim clips.

I've posted on ebay, but no watchers :(

Cheers for the reply.Yes was going to replace the lot while in there, just wanted to see if anyone thought it could be something else. I am doing it on the drive, is there much room to get it out?

Sorry not sure on this one. 

I assume when you plugged VCDS in that all modules were live and talking?

If running rough that could imply a timing issue and it could have jumped a tooth

Agree........Sounds like the release bearing.

If going into the box to change, you might as well to it all (bearing, slave, DMF and clutch)..........a while your in there job.

If doing it DIY style like I did on the drive...........note the box is blooming heavy!! I did the wifes 1.6 FSI the week prior and the box even though it was also a 6 speed, was half the weight

Mk5 General Area / Golf Gti rattling/tapping

« Last post by Thannant1 on April 14, 2026, 10:43:47 pm »

Hi, any help would be appreciated.
My mk5 gti has recently developed a tappet sort of noise that when driving will increase with engine speed but disappears when I press the clutch in. It doesnt make the noise when not in gear but there is more of a slight knocking and rumble at idle that again disappears when the clutch is pressed down, thinking that could be the release bearing or dmf. Could the noise when driving also be caused by the dmf?
Thanks in advance.

Performance Modifications / Exhaust

« Last post by Numero9 on April 14, 2026, 02:06:59 pm »

MOT has picked up the centre box on the exhaust has started to fail at the weld, so decision is either to just source a second hand centre box and fit it OR new exhuast to make more fasts!

Question is are Miltek still the people to use or are they some other slightly cheaper alternatives about?

if I go with a 3" catback would I need an adaptor to go from the cat to the new section?
