Hiya,
The Beat has been fine lately, at least that is what I say when I am asked.
BUT today the mil (engine management) light came today on 20 miles from home, it drove back fine, temperature guage at normal, revs up to the limiter both on revs and speed, but the idle had gone up to 1700 rpm hot and 950 when it's cold. and interrogating the ECU threw up code 6 indicating the tw (coolant temp) sensor, which makes perfect sense to me. now, I'm presuming this is the one on the thermostat housing in the knuckle scraping space under the Dizzy!and is probably going to be a sod to get and will need ordering from Belgium or Japan. Does anyone know if this cross references to any other coolant sensor please?
I am also presuming that the dash guage is sensed elswhere as it is reading normal.
As someone is likely to mention check the ECU capacitors I have checked them and had a light and magnifying glass on them and they are like new, but if they need changing I still have a couple of uprated sets.
Any ideas?

Nick
