when ac is on, there is no cold air and the radiator fans don't turn on.

changed the G65 pressure sensor, had no effect. pressure sensor show 7 bar pressure

checked refrigeration gas with gauges and low side 80psi - high side 60psi , but even though these aint the ideal pressures they would correct themselves if the ac kicked in.

did hvac test and there is current going to compressor.

did an output test and when it tests the RCV the radiator fans kick in, so they must be ok?

and looked on ross-tech wiki for the following fault and couldn't find anything -

005697 - Please check DTC Memory of A/C Controller P1641 - 000 - - Intermittent


any help on what to try next would be great :-)

005697 - Please check DTC Memory of A/C Controller

That just means that the ECU is aware of a fault in the HVAC module. However, it's flagged "Intermittent", meaning the fault condition that set this code did not exist (or could not be detected) at the time the scan was performed. I'd speculate that the fault(s) in the HVAC module have been cleared, but not the the ECU...

thanks for your response Uwe

how would i clear it in the ecu so it don't show up again?

also would that be the same for all the other intermittent faults like -
005746 - Coolant Fan Control 1
P1672 - 000 - Open or Short to Ground - Intermittent

If compressor is taking current but not operating it suggest it is faulty or stuck. remove drive belt and see if you can physical turn the compressor inner and outer by hand

Note that you cannot prevent a fault code from being set again if the fault condition re-occurs.

According to your second picture the compressor should be pulling 0.8amp but the actual reading is blank. give the compressor clutch a good live and earth, see if it then pulls the clutch in and works . Obviously stay well clear of any moving parts.

The compressors are known for shear pin breakage in addition if you find that the clutch engages after jump out advised by paull.

Mine doesn't have a clutch, it's always engaged on the mk5s.

Guys there are no clutches to speak of on these any more. That's what the N280 is for on the compressor. That's PWM'd and have swash plates inside on some. Do check the spindle as stated as they do fall apart internally and the two separate on the front of the pulley. Done loads in dealer and out of.

So take the aux belt off and turn the spindle and see if it feels like it is turning the inside cogs etc?

If it spins freely then it's nackered lol

Just been looking into the other faults, manly the aux heater.

says it defective and was just about to order a new one and i remembered i can do a output test with my new favourite toy ( Ross-Tech HEX V2 Lead ) so i did a test and the aux heater booted up strait away and was on, but it wont turn on manually , only with vcds - strange. what could cause that? sensor?

picks attached.

That is not the case worldwide........ and a shear is a shear.
