Hallo, i just bought an XJ12 Daimler from Japan. I made about 550 km on a Highway with no problems but sometime the exhaust temp warning lamp was warning. I red it is only mounted in Japan cars. Do you know what does it speak for? What should i check? When i drive more then 140 kmh it disappears and is flickering between 100-130 kmh and disappearing in the city....

Check your ignition timing. If your timing is retarded it will cause the exhaust gasses to be very hot. Your xj12 has a centrifigal mechanical timing advance which is known to get feststecken. Also check the vacuum advance unit too.

 

Thank you very much. I will check the ignition. It dose not light regularly, only sometimes when i drive slowly.
