I'm also lead to believe that it could have a software conflict! For a cooling fan on a 10 year old car !!! ??? What is your data source for this ? I can see the benefit of an update, I wouldn't be applying it to the car though ! Is this another hypothetical example ? Back in the 1980's when I comp...

Had the timing jumped too ? Otherwise that broken plate does not explain the low vacuum or have I missed something ? I believed the timing had jump from his scope traces! I not sure whether the engine actually run! With this in mind, I'm thinking along the lines of the following; When the starter m...

That must have sounded terrible when running, and starting that engine must have been a nightmare!

John,

You should start a new thread in 'help fix my car'

There is a clear difference between a bridge rectifier and a wheatstone bridge, just so we are singing from the same hymn sheet :wink: Some (VAG, Merc ...) Will use a 3 pin component to send both Pressure & Temperature on the same wire. However, if you can see 120c then clearly the issue is ECU, Wi...

Thanks for replying STC I didn't use the scanner, but you know I have the VERUS. Must admit STC the AD wiring diagram showed a potentiometer and nothing like a wheatstone bridge, the latter looking like a bridge rectifier made up of four diodes, but is constructed using four resistors, the potentiom...

Interesting problem appeared on the above cars cooling system. The customer advised the engine overheats, someone has already established that the radiator cooling fan is not receiving a live supply. Referring to the wiring diagram I concluded that there are two relays fitted, a low speed and high s...

I can't remember but is the crankshaft timing gear sprocket a fully floating type or is it keyed !

Thanks Danny, so you are saying that until the fault code has been cleared the eml strategy will remain illuminated!
