Hot Problem

Post by candhdyas » Fri Sep 24, 2010 7:44 pm

Hi, new member so first post.

Merc V6 E240 2001 with AFC components fitted. When cold, all behaves as expected changing to gas about 60 degs. When started at full running water temp, and only intermittently, the car refuses to change over to gas.
I guess its the shut-off solenoid or the regulator, but need help to identify which. Any experts out there who can help me pin it down?

How many miles has the car done? I see it is a '01 model - due the 10 year "major" service. Given that there is a slight residue build up in the LPG system, it sounds to me like a sticky solenoid valve. Could be as simple as a remove, clean and replace, but definitely a job for a specialist.

Curious enough, just today the PT100 tenp sensor fell out of its holder...Dho!...I wonder where the problem is... Got a spare so will fix it tomorrow. Many thanks for my one and only reply.

Hi Hugh,

It would make sense that faulty (or missing) coolant temp sensor could cause this. Let us know how you get on.

Sorry for the delay in answering, its taken a while to sort it out and I wanted to run the car for a couple of weeks to make sure it was a permanent fix. In the end there were two problems. The Gas one turned out to be thetemperature sensor in the reducer (already guessed at) which was intermittently faulty, but this was complicated with the Air Mass sensor inthe air filter which was also intermittently faulty and up-setting the enging management. Seems that one fault was disguising the other. Both components changed and a good service and the car is performing brilliantly. Many thanks for your interest in this. Hugh
