Hi I'm new to this forum but have researched many threads plus youtube videos etc. I have a 2004 T5 2.5 (I believe it's an AXD engine) which has a problem starting first thing in the morning in cold weather. Last winter I swapped out loads of parts including relays, fuel temp sensor and even had the fuel tank out to replace the in-tank pump! Nothing solved the problem and the weather's just turned cold enough for the problem to manifest itself again. I've tried to avoid changing the glow plugs due to the access issue, however I don't think they're the problem. The symptoms are the engine cranks over fine but doesn't fire at all, not even a sputter. As the ambient temperature increases (usually while I have a coffee for an hour or so) the engine sputters a bit on cranking and I know at this point I will eventually get it started. However it fires up to about 2k revs then dies immediately (almost as if the ignition is switched off). It does this half a dozen times or more before finally staying running but I need to keep the throttle open for a minute or so before it will idle without dying. After a few minutes it will run and drive fine and no more starting issues all day until the next cold morning. To me this doesn't seem like a glow plug problem and I'm now leaning towards the fuel shut off solenoid. From what I can gather this solenoid is an integral part of the fuel pump so I'd need to change the entire pump, is this correct? I see you can buy solenoids but they all seem to be for the 1.9 engine. Has anyone experienced this specific problem and am I on the right track suspecting the solenoid? There are no fault codes showing on the VAGCOM hence why I think the solenoid is sticking shut when cold rather than there being an electrical issue. Help, suggestions or confirmation much appreciated!
