Does anybody know if the mk4 has an air intake temperature sensor in the HVAC (G89) because according to the diagram it does however the pin out at the back of the climatronic unit would suggest otherwise.
The reason I’m asking is because I get a climatronic code 313 which relates to g89. I have put vag com on also and it reads -99 under the intake temp sensor block so I can understand why it has flagged the fault, the mystery is the 20 pin connector has no white and red wire at pin 13. It has no wire at all, just a blank in the plug. I can put a pin in and bridge it over to the sensor earth with a resistance in between to get the measuring block to change temperature which would suggest I would be able to get the air con to work if I set the resistance or the right value.
I took the climatronic unit apart and I found the solder pad had fouled on the casing and it looks like it has bridged to another component. I bought and fitted another unit from a breakers to no avail so I opened that one up and found the same rub marks on the board, there was no evident bridging though. Does anybody have any suggestions where to go from here to get my air con back up and running? I’m going to try a variable resistor next and just put the ‘missing’ pin in.
