I read fault codes from ecu. It gave 65, CID circuit, which is not present in my mk1 valver. Any idea/knowledge what it might be?
The idling problem is high revs when warm. It runs about 1200 rpm. In warming period it seems to run more close to the correct value. I changed the temperature sensor, but didn't have any effect. Can it be intake air temperature sensor. Diagnostic test tested idle actuator and at least it was moving during the test. Any ideas?

Re: Fault codes and idling problem
Hi, do you have the list of fault codes?
Is it possible to read the codes from ECU without having a diagnostic machine?

Re: Fault codes and idling problem
Yeah, I found out that at least on mine (results could vary) I can actually read the errors without having to go to the diagnostics plug next to the wheel under the bonnet. Just put the key in the position before the engine start, and turn it slighly towards the start position but stop just after the cluster lights go off, and before it engages the starter motor, and then go back to the previous position. Basically that works out as the wire you would have to use in the diagnostics plug, but you don't need a wire and can read the error from the flashes of the engine light!
