Got a few issues with my Audi, which thanks to this forum I have sussed out the problems! I'm going to be getting some Mr Muscle at the weekend! And an EGR plate! However I am struggling on my starting issue. I have replaced everything in the pre start system. So glow plugs, glow plug relay, temp switch in the cooling system. I haven't replace the battery but it doesn't drop below 10V when cranking. The glow plug comes on in the dash for four seconds then when cranking it turns over for 15 secs then it fires on a couple of cylinders and finally splutters into life. Could it be the battery? Is there any way to test this other than buying a new one?! Struggling on what left to do. Is it possible it could be the fuel pump or injectors? It only happens when cold, however even when warm it doesn't fire instantly like my previous TDi's have. ANY help will be much appreciated! This forum is bloody useful, I'm so glad I've found it!
