Thread: 300tdi no start when hot

I had this exact problem ended up being the starter was on its way out.....it started with slow turn over in winter and progressed to engine not starting after long journeys to engine not starting a short journeys on hot days..

Never had an ounce of trouble since changing starter probably 1.5/2 years ago

Strangely enough, it could quite easily be an earth problem.

Before you splash out on a new starter, next time you have a problem starting, test the earth theory by running a jump lead from the -ve to one of the starter bolts.

Thanks guys I have checked the earth connections are OK and the starter doesn't sound like its on the way out as it turns over fine when it want's to work.

yes of course could be an earthing problem like CL has suggested...thinking about it mine when hot wouldn't start but that was due to not having any starter at all wouldn't even turn over until it cooled down....So probably unlikely to be the same problem if your is actually turning over

I had similar, starter motor would not throw in, thought it was the solenoid going, after several clicks of ignition (some times up to a minute later) it would start. Eventually battery died and new battery fixed it. That was two years ago, though my starter motor is on the way out, as it runs on some times after starting.

Unless you have a direct connection from the battery to the starter, you're assuming that everything else in between is working. Unless you have that direct connection, the only true way is to test it with a jump lead to eliminate it from your enquiries.

the problem is that their is nothing happening at all not even a click of the solenoid but once it cools down a bit it starts no worries

It makes it hard to test the starter when the turbo is so hot and close to the starter and once it is cool enough to check it will start OK
