V6 CDI glow plug replacement, light still on?
Last time i had the cls put on a star machine it brought up a fault code for cylinder1 glow plug. I did have the usual glow plug light stay on till it got warm,decided to ignore it till now.
Any way i replaced the glow plug at the weekend but i still have the same issue with the glow plug light coming back on till the engine gets a little warmer.
Am I right in thinking that cylinder1 is to the front of the car on the drivers side bank.(R/H/D uk car).
It could be that its got more then 1 faulty glow plug. Any idea how to test them?
Can any tell me if i need to get the fault code removed or will it stop coming on over a number of starts?
