So I've been having a dodgy outside temp display on the dash recently. I got a local auto electrician to come and have a quick look at the car. He said basically the problem could be anywhere from the instrument cluster to the wiring through the dash and the engine. He suggested wiggling the wires and see when the temp reading starts to go crazy (as the fault is intermittent, and ive noticed it go funny when going over bumps).
What i've done is hooked up VCDS, ran the advanced measuring blocks for the ambient temperature and started wiggling all the wires from the sensor up to around the battery area. What I did notice is that the temp starts to drop when I shut the bonnet!
It turns out when I hit the top of the dash above the instrument cluster I get a drop in temp,.
What are my options for getting the cluster sorted? I hear ecu testing can test and refurbish the cluster but that's gonna be over 200 quid. Are there any other options?
thanks!
