Won this beautiful black A3 SE TDi off eBay, complete with R32 alloys and all the toys inside, heated seats, cruise control etc.... It was advertised as having a blown turbo.
Now I have owned a BKD engined car before and upon collecting it, the turbo was fine, it has the usual whine these engines have, but when giving it some it was flat as a pancake. I then went on to find 3 boost hoses just not even held in, one going to the ASV, and the other 2 underneath, from passenger side of intercooler leading up the ASV, at both joins there had also gone, so i drilled and screwed all three. It now pulls like a train.
I am just left with 3 issues.
One - There is an engine mount knackered, i cannot workout which, but its rocking back and forth like mad and its chewed up all the sound deadening on the back of the bulkhead at the back of the engine
Two - It won't idle properly when warm, its fine when its cold, but when warm it all over the place, sounds like its misfiring
Three - It doesnt like cruising or being held at between 2000 and 2500 revs when driving, if you try to cruise at these revs it just starts misfiring and lurching forward/kangarooing
So I have full Vagcom on my laptop. I did a full scan and found ZERO fault codes on the engine.
I then did research and to date I have done the following.
Removed cam cover, unplugged each injector one by one and started it after unplugging each, this only made it run ten times worse and it threw a fault code for each Injector i unplugged, plugged them back, in, put it back together, cleared the codes, took it for a run, rescanned, no codes, and still the same problems mentioned above in 2 + 3
I then removed the fuel filter, to check for a bad filter, and for water or oil in the filter housing, suggesting maybe the injector seals had gone, and the fuel was fine and free of contaminants
I then bunged up the vac hose to the EGR and blanked it off using a plate. No difference whether its bunged up/blocked off or not.
Its a bit hesistant starting, it sort of like makes that sound when batterys flat where it cant quite turn the engine over then it dies? but once its made that first hesistation it fires into life?
There is no smoke from the exhaust, when cold or warm, it does chuck grey smoke out but that was only when the boost hoses were loose, doesnt seem to do that now.
Problems just seem to begin once the car is up to temperature, the dodgy idle and the not liking cruising at 2000 - 2500 revs
People are saying injector wiring loom, the turbos coked up, or the timings out.
Its only done 108,000 miles on a 04 plate, and it had a cambelt at a non dealership garage at 103,000 miles.
Can someone suggest anything else I can check ? it rattles when i turn it off, which points to the ASV, but then my MK5 did this and it threw a code the ASV was knackered, but this hasnt?
Can anyone tell me how using full vagcom I can check the timing, check what the injectors are doing, and boost levels ?
Many thanks
