Starting

I have a 1.8L 1999 Passat with 105,000km. When it is hot out and it is parked in the direct sun, it will not start. You turn the key, the dash lights up, but there is no turnover; nothing. It will push start and drive fine. If you let it sit for a while in the shade or the garage it will start without a hitch and continue to do so until you once again leave it parked for an hour or more in the hot sun. Any ideas? The starter, Ignition Control Module and Battery were replaced in November of 2003 and the ignition was replaced in January of this year after theft recovery (It had been punched).
Do you

I would hazard to guess the starter solenoid is the culprit here.

I had the same problem last summer with my 1997 VW Jetta GLS! Only now that it's winter, it's not starting if the engine is warmed up, I have to wait (usually stranded somewhere) a couple of hours or so for the engine to cool off before it will start.

I also had my battery, alternator & starter tested and all came out fine. The starter is only about 3 years old. I read somewhere about a clutch safety switch that engages when you push in the clutch so you can start the car, does my car have this? Is it possible this may be the problem? Please help! [/Quote]

These ones are the ugly ones.

Seeing that you checked out most of the relevant starting points it leaves very little. I would have to go back and try a starter solenoid change. That is the unit that actually connects the starter motor to the battery. (And would be hot when the motor is hot.)
