Here's an odd one that I'm hoping that the brains trust can assist with.
My '94 300tdi D'Fer occasionally fails to proceed. And after lots and lots and lots of new bits being thrown at it, I've finally now narrowed down the problem, but I am completely baffled as to where to go next.
When I turn the key there is a single loud click. Before you go there, new ignition, new starter and solenoid, new earth cables, additional earth cables, new batteries ... if in doubt it's new including the under-dash relays. It's also not earthing via the handbrake cable, clutch etc.
So in order to get it to start, what I have to do is roll it forward or backward slightly in gear and then release the clutch. This puts load/pressure on the engine/gearbox/flywheel etc and the vehicle abruptly stops with a jolt on it's compression. To give you an idea of how fast, it's not even close to being able to bump start. But it is enough to mesh the gears and everything else in place.
Once this is done, I push the clutch in, then turn the key and it starts immediately every time.
It's as if the little gear that the starter motor spins out to engage on the flywheel is getting stuck on something. The starter solenoid then clicks out under the load to stop the solenoid or starter from damage.
I'm hoping that this makes sense. Has anyone had this happen before?
Thanks in advance!
