Volkswagen Golf V diesel - Bubbling and rocking in idle also trouble to start - bornin78

Hi, when I am sitting in traffic and the car is idleing either with my foot on the clutch or with the handbrake on the cars bubbles and rocks, you can feel this in the car to the extent the handbrake and gearstick rocks. Also the car is sometimes hard to start, not always. I have changed the glow plugs. The car is a 55 plate Golf and done about 98000 miles.

Yes, it definitly sounds as though its down on one cylinder, I am not familier with this particular engine but I think a faulty injector would likely be the problem.

I think I would be checking the camshaft lobes for wear ! common problem for wear when they have run on the wrong oil.
