Well I suppose it had to happen sometime; after many years of fault-free service our TDi has finally decided to throw a fit.  After an uneventful drive to work yesterday (to dodge the train strike), when I started up to go home I was met with a fair amount of vibration, and a noise that sounded like a mini tractor.  There were no warning lights, and there was no sign of belt damage, obvious leaks or split hoses, and the coolant looked clean and the correct level.  It's a 54 Reg TDi Sport with a measly 82,000 miles on the clock and we've owned from 18 months old.

Any ideas before I throw myself on the mercy of someone who knows what they're doing?

And when I get there, does anyone recommend a specialist in or around Leeds?

are you suggesting a missfire?

too vague on the description.

If it is a misfire, I'd suggest the wiring to the injectors, they do break down over time. Means you have to take the rocker cover off to check though.

Sorry @Rich, yes.  It seemed to get a bit better once I was moving.  I'll take the cover off and check the injector wiring as suggested by @lupogtiboy.

When running on two these 3 pots are rough as a dog, mine did it when i got the fuel hoses the wrong way around 1st time i removed them, so a misfire is very very obvious.

Injector loom is likely suspect as already said, vagcom should show faults.

yup, two pot is terrible.

sometimes a terrible three can just be a green temp sensor.

Interesting thought;  We had an intermittent engine electrics warning light a few months ago (but with no obvious symptoms), and when we had it diagnosed it came back as a temperature sensor problem.

I think embarrassment might be my middle name.

I realised after driving home that it sounded a lot rougher than it felt. A good look underneath in daylight revealed that the joint at the rear of the catalytic converter has completely failed (see the picture), and the front exhaust bracket also looks like it’s parted company from the pipe.

Hopefully it should be a relatively easy fix.

Decat and sell yours for pro£it.

Tbf, my brother had a Mitsubishi Delica about 10 years ago and thought the engine might be knocking so wanted me to look at it, sounded alright idling, went for a spin and it was exhaust manifold blowing on the head so easily done.
