- Sorry if you can't read the VagPro OBDII reader... cheap LG Android phone. Coolant engine temp was reading 88-90 C. Was a little off converting to Fahrenheit. So I think 121 C = 249 F.
Press and hold the recirc button / up arrow. Should see a 1c. Then use the temperature up (+) or down (-) to select what to display. Then press the recirc button again. The value should display. Press the temperature up or down button again to display another code. Press recirc and up arrow to go back to regular climate control functions. Remember this code list will be different vs A4s and other Audi models.

Hi I'm Paul from Germany and i've got the same problem with the temperatur. But I think i found the problem. First you should know that there are two sensors. One for the ECU and one for the Cluster. This double sensor ist called G62/G2. Both are resistance sensors. So the ECU and the Cluster have a voltage source which sould source a voltage of approximatly 5 volt. From my point of view you have the same porblem as I have: the voltage source in the cluster is defect. You can check that if you measure the voltage at the plug of the sensor:
Pin 1 and 2 are the contacts for the G2 - for the Cluster
Pin 3 and 4 are the contacts for the G62 - the ECU
As you can see at this german TT page: www.tt-eifel.de/index.php/technik-8n/motor/geber-g62
I think you will measure a voltage below 1 volt between Pin 1 and 2. At the Moment i don't have a solution for the problem but in Germany there are a lot of companies which fix the display of the Cluster, maybe the can help. If you have a solution pleas contact me with all the details you have!!
Greeting from Germany
Paul
Thank you for the info Paul. I was messing around with it yesterday and gave the instrument (right between the temp and fuel) a good wack with my first and it moved to almost normal. So definitely something wrong on the circuit board or stepper motor of the gauge. I have experience with BMW and Mercedes instrument clusters failing in some way too. Old E30 chassis 3 series would have the NiCad batteries fail in the cluster and cause failures. In Mercedes (210 Chassis) E320 ribbon cables would lose contact from heat and cause LED (LCD?) to not display properly.
For that site, is there an option to translate to English or I will have to do a cut n paste to a translator?
Doing some driving today checking for any issues the temp fluctuated back down to one line above center then the display on the climate control 49 C read 88 c... which is normal. Still not perfect but it's almost fixing itself as I drive it. Was sputtering at 3k rpms but I never change the spark plugs out and no clue how old they are so will so that tomorrow. Otherwise running very well after the rebuild.
The eifel tt website is only in german available. Maybe google is able to translate the whole page. When your sensor is working after a hard knock I would say that there is a cold solder joint oder a break in the PCB and with the hit you brought the two contacts back together.

With stuttering at full throttle at 3000 rpm I would first suspect the ignition coils.
