Next on the list was to replace the Coolant Circulation Pump, as I have having a problem with heating in the car. Some of the vent would blow cooler air, when other vent would blow red hot air. I was getting the following fault code.
1 Fault Found:
00739 - Coolant Circulation Pump (V50)
001 - Upper Limit Exceeded - Intermittent
Freeze Frame:
Fault Status: 00100001
Fault Priority: 3
After a bit of googling I found the faulty device.
Here is the replacement Audi have revised the pump with part number 4F2959617B the old part number was 4F2959617A
I first removed the brace bar as it gives a little bit more room to get the unit out.
The instructions then stated to clamp down the pipe next to the pump, then remove the 3 nuts holding the pump unit in place.
Next is the painful bit getting the clips of the 3 hoses which are circled on blue and remove the 2 electric connectors in red.
Once removed it's the case of refitting the new pump in reverse order, I also pored coolant in the hoses (to help reduce any excess air in the system) just before refitting each them starting with the lower hose first.
It was then the case of clearing the fault code and giving the car a test, as it mainly happen during town driving and sitting it traffic, and so far the fault has not reoccurred.
