Hi All,
So hadn't driven the car in a few days so took it around the corner to do the weekly shopping in Dunnes. Car started fine and drove as normal, or so I thought. But noticed that the revs on idle where higher than expected and were not dropping, staying around 2000 rpm. Thought it might be the idle control valve, but had cleaned that recently enough. Just as I was swinging into the underground parking when the CEL came on and revs then were dropping and rising between 1500-2000rpm on idle.
Got car back to the house and bought a code reader today (Argos job, https://www.argos.ie/static/Product/partNumber/9112449/Trail/searchtext>STREETWISE.htm).
When I plugged it in it did not power up no matter what I tried (ignition on, etc.), so I tried it on the Mrs Golf and it powered up straight away. I did not test the code reader any further than that on the Golf.
So any ideas as to why I am not getting the reader to power up even? Fuse for the OBDII port? Or is it a common thing for people to put in dummy OBD's, etc. (have heard of lads doing that with mk2 Focus ST's, as can start them through the OBD)? I saw a connector block near by not connected to anything. I did not spend long as is raining and I am meant to be at work So will try later.
Or is my symptoms a common problem that can be diagnosed without the reader
Thanks all.
