Today my A4 developed a fault which have to say has stupped me for the moment. The car is a 1996 A4 with a 1.8T AEB engine. I'll go through the steps that I've already done. First tried a new coil pack in each cylinder Second Tried a new set of spark plugs (currently running Bosch, tried NGK) no difference Disconnected the plug going into each coil pack until the faulty cylinder was found. After disconnecting each plug one at a time to each oil pack, 1, 3 and 4 caused the engine to start the stop after a few seconds Disconnecting the plug on cylinder 2 made no difference Tried the new coil pack again on 2 made no difference Swapped coil packs on 2 & 3 around fault stayed with cylinder 2 Check with VAG-COM 10.4 beta and no faults codes were showing on the engine There are no grinding, banging or rattling noises, so I don't think the piston/valves are at fault Oil is a nice golden colour, there is no water in the oil or vice versa, so don't think it's head gasket. After leaving the engine for a while the car did start normally, and was running nice and smooth until the temp got to around 70 then cylinder 2 stopped again. What I want to try the following but now sure how. Want to try and see if there is power going to plug 2, but don't want to fry Could this be an injector problem how can I test for this, without setting the car on fire!
