Hi all,
have an issue with my van, a 2003 SWB, short-nose 102bhp 2.5 TDi, Combi (twin slider) van with 103k on the clock. I've owned the van for a couple of years and know its full history. Cam belt was done when I got it with 90k on the clock.
Its had the "problem" since I've owned it, but it's not really bothered me as there is a workaround BUT, I have to sell the van, so I'll need to fix it.
It goes like this - when about 50% of the time it will start first time, whether the outside temp it high or low makes no difference. The glow plug light stays on for a very short time - around 2 seconds, then goes out. If it is going to start first time, I don't even really need to wait for the glow plug light, I just get in, turn the key and (if its going to) it starts.
If it doesn't start, the only way to get it to start is
turn on the key, watch the glow plug light go out, listen for the "click" of the secondary glow plug relay. Immediately turn off the key and back on and listen for the relay again, then of and on once again (making three relay "clicks" and when the relay clicks on the third time, start it. Never fails. If I only let the relay click twice and try it will start but needs a lot of cracking and runs rough and smokes like anything. Thre times, and it starts instantly every single time.
When I first got it, I thought I'd fix it - so did a bit of research and changed the glow plugs and both temp sensors as they seemed to be prime candidates.
looking around tinterweb it could be a number of things from ignition barrel, to relays to dodgy earths. I have VCDS and there are no codes showing. Assuming its not timing as a) the belt was done by a specialist and b) its intermittent.
Anyone had/ seen anything like this?
Cheers
