[elizabeth33]

Can anyone help? I have an Audi a4 1995 1.6 ltr
My car will only start when the weather is cold,if it is a hot day it is as dead as a dodo!
I think there maybe a heat sensor somewhere expanding but i don't know where once the car is push started it goes fine-until you switch it off!!!
has anyone got any ideas PLEASE?????

hi, do you mean the starter motor doesn't turn the engine over , or it turns over and doesn't fire up?

Hi.
when the car has been sitting out in the heat it will not turn over at all.
all the dash lights come on but nothing happens.
i hae just had a new solanoid fitted in the starter so this is not the problem.
i was wondering if it could have something to d0o with the heat resister on the starter or the the ignition circuit?
when the weather is cool it has no problems starting at all

i would start with simple things. it sounds like the starter has been messed with recently so i would check the power cables to the starter and the earth . just check for tightness and remove them and check for corrosion ect clean up re-fit and try.

when it is cool outside it starts up first time no problem.
