Hi all anyone know any popular problems that bring on the EML, I'm hoping its not going to be an expensive job as I have just bought my ticket for AITP
Scan for faults... clutching at straws else especially as you haven't specified any symptoms....
Silver 2001 AMK S3. Silver alcantara interior... now with added powarrrrrrrr, torques. VAGCOM + KII-USB. >> My build thread...
Get yourself to Midland VW mate, they will be able to get it sorted for you.
Have you explained the issue to him, if not, have a word and see if he knows what it is thats causing the issue.
That fault is 99% related to a duff coolant temp sensor. Buy a genuine green one from Audi/VW/TPS /Seat, & change your self for £34
TBH in my experience the Thermostat is more likely than the CTS.
You can often tell simply by how the temperature gauge behaves. Thermostat will allow the engine to run cool, ie the guage will never get to 90c, until your stuck in traffic or sat idling on the drive. If the guage often sits below 90, and climbs if left idling for 10mins, then i'd be changing the thermostat first.
If the guage quickly comes up to 90c and never moves, then its more likely engine side of the CTS is faulty.
thermostat is quite an easy job. Would give it a go yourself if you have a load of extension bars. 30-45 mins if you have done one before, bit longer if not. Just awkward to get to. Temp sensor is 5 min job

just check comparitive temps in vagcom before condemming the thermostat.
in the CTS there are 2 senders, one for instruments one for ecu..
look at both temps (engine + instruments) when its warmed up and confirm they're the same) If they are, its unlikely to be CTS.. If your temp wavers about or does'nt get to 90, or rises and falls from 90, as confirmed by the engine + instruments reading then it is thermostat
CTS is the cheaper of the 2 to swap out.
