1999 golf mk4 gti 1.8 t
« on: 27 October 2016, 11:15 »
Brought a mk4 golf and the center screen that displays the mpg etc doesn't work the immobiliser kicked in and wouldn't let me start it then suddenly worked and haven't had any problems since the odometer now has stopped working until you turn the engine off then the miles go up is this a common fault? Or any easy fixes?

Where are you in the country?

I would first check that connector is plugged in at the back properly.
If that is all in the speedo might be acting up - which is why I asked where you are. I can help you with either repairing speedo or fitting a replacement, including matching immobiliser etc.

What part number is your speedo?
And which make is it (VDO, Bosch, Motometer)?

On the back or if you have a diagnostic system you could read it via OBD.
If you have a CAN bus speedo things are much easier - i.e. if it is 1j* 920 *** * it will be CAN. 1j* 919 *** * does not have CAN and they are rare and quite a lot more expensive.

Also went to the petrol station filled up reset the odometer,started driving and said I done 10 miles when I had only just left the petrol station I then noticed the heater dials light went out until I reset the odometer then the lights came on again could this be related to the speedo /immobiliser issue?

Might be a wiring issue. Though it showing 10 miles after a short distance sounds like there is an issue in cluster.

You have a CAN bus speedo - which is a good thing. Do you have a KKL cable and diagnostic software (VCDS lite or wbhdiag)?
Then could send you a spare speedo (it's a diesel on but would work for testing but trying to get a petrol one back that I lent out).
