Collant Temperature gauge
Collant Temperature gauge
OK So not sure what is it but my Temp gauge stopped moving.
Don't know if it's a temp sensor or the gauge on the cluster itself.
Checking the temp with a bluetooth diag tool it's showing the temperature correctly but the needle wont budge. From time to time I have seen it jumping to 90 deg but that didn't happen for a while now.
Are there more than one temp sensor ?? and one is broken or it's just my speedo gauge broken ??

Re: Collant Temperature gauge
It's a dual temp sensor. Use the Vagcom to check both. Or just replace it. They fail often.

Re: Collant Temperature gauge
I assume it's two same sensors ??? not like to different types/plugs...
Re: Collant Temperature gauge
I just changed mine for simular reasons. Gauge was either at 90 or 0. So far it's seemed to of fixed the problem. It's one unit with 4 pins. (to sensors in one unit)
Re: Collant Temperature gauge
Thanks - Found some details on it now. one sensor called Dual with four pins sits at the back between bulkhead and engine.
Re: Collant Temperature gauge
It's one unit (the green type probably) with 4 wires in the plug and 2 sensors inside.
One typically tells the ECUs what's going on, the other the cluster, so things can seem very inconsistent.
ONLY EVER BUY A GENUINE ONE FROM VAG. And get a new clip and O-ring with it.

Re: Collant Temperature gauge
$113.00 from Audi for the sensor and O-ring. Only about a spoon full of coolant lost. I tied a thin peace of wire to the clip so I didn't loose it down the back of the engine. Just cut it off once the clip was refitted.
Re: Collant Temperature gauge
Having done this a few times (until I bought a genuine one!) my tips are:
1. Release pressure at the header tank, then put the cap back on tightly. You'll lose almost no coolant.
2. Wire or twine around the retaining clip, it's so easy to lose!
3. Releasing the wiring connector can be a pain, orient the replacement so that the release mechanism is easy to get at next time.
4. Wiggle the old unit carefully and then dig out the o-ring, assuming you have a new one. Then clean the socket out.
5. Putting the new one in may need a gentle tap with a rubber hammer or similar, it's a tight fit.

Re: Collant Temperature gauge
Thanks for the tips guys - will tackle that today
Re: Collant Temperature gauge
That's all done now. All fairy painless. Struggled with pulling the old one out. New went in nice and easy - just a gentle tap and a lot of starches on my mahooosive hands as I was trying to push the retention clip in.
