Chasing hot start issue
Hi folks, my 1996 C4 developed an issue where once hot, if left for half an hour would refuse to start. There is just a sort of wheezing/whirring sound then a clunk from the starter . Come back later and it starts or if you don't leave it too long.
I notice that there isn't always a hum from fuel pump when ignition moved to first position. Other times there is an audible hum. Does that mean anything?
Things I have done:
New earth strap in luggage area.
Cleaned contacts on starter earth up near rear shock tower.
New distributor, rotors , plugs and new wires have already been fitted .
New ignition coil.
Is this inevitably the starter do you think or is there anything else I should try?
Thank you!

I assume you tried a different DME relay already although not mentioned.

Was this work done as an attempt to fix the problem or did the problem manifest itself after this work? In which case I would double check all the connections. I think there is a DIY to test a coil too. I had a friend with a motorcycle that wouldn't hot start and ended up being coil.

Can it be the starter motor? I had similar issues. Once hot, when I stop the car I wasn't able to start it again... it happened twice and the first time it started normally after an hour. At 130k miles rennlisters told me it was not surprising.
