Hi my temp gauge has stopped working in my B6 a4, any ideas any body??
Scan with VCDS or check wiring at the CTS. There is a way of getting the dash dials to do a self-test. But I can't remember the process.
Here you go It's done via vagcom
Was working fine then today zip, doesn't move at all not even a blip when you start her up...... Also any one got a rear number plate light assembly as mine dropped out on the way to work this morning
Coolant temp sensor has probably failed. Very common problem.
Temp sender has had it or check the wires on the plug,
You really need to have a look in VCDS/VAGCOM engine measuring blocks to see if the ECU is getting a correct signal from the CTS.
Even if your stat was stuck fully open I would still expect the temp to get high enough to register on the gauge.
Does your heater get hot?
Yeh heater works ok trouble is got no hook up to vagcom
Change the temp sensor as you say you have heating as it is very easy to do but make sure you have a bottle of G13 coolant to top up after......very common problem, but usually it sticks to the 70c marking and never reaches 90c.
Showing my lack of knowledge on these cars..... Is there a guid on here or any one got a pic of where it's situated?
do a search there is shed loads of info on this and guides with pics
it will also help if we know what engine?
location in your profile is good to so if there is anyone close by with VCDS they can plug in for you
