Everything works except the cooling system.

New compressor, System pumped up.

But not blowing cold?

 Any idea's. 

The Air con garage have given up?

@tbonez - Any fault codes? If you've got refrigerant, a working ventilator fan and a reasonably new pollen filter it should work.

Have a VCDS scan done and then check the compressor shut off codes under measuring blocks. Also the system pressure.

 

For whatever reason be it a broken cable, low system pressure or another compressor shut down code the modulating valve is not being commanded, the high side pressure is not going up & hence the radiator fans wont be cutting in.

 

I cant believe that this is really an "aircon garage" that you are speaking of if they have no clue other than playing parts bingo.

 

How much have they already stiffed you for?

Hi,

Many thanks for the info.

I'm getting no codes for the air con. system.

Costings + have been a recharge twice price.

Actually two garages. One who installed the new compressor. ( which still didn't work)

The other specifically have more equipment & kit, & spent another 3 hours trying to get it to work.

They did mention the electronic control system may have been the problem?

All the controls work from the inside still (temp. fans etc) but not cold.

 

I wouldn't even guarantee it blowing Baltic if you set the demand temperature to "lo". It should blow below ambient ( value from trip computer) though.

Thanks for that.

On what diagnostic equipment?

 

A standard OBDII reader will not give you fault codes from the Climatronic controller let alone measuring blocks and compressor shut down codes, for that VCDS or the equivalent is needed.

 

A Snap-On pro reader the like of which most garages will have would get to the module and show any fault codes but not (to my knowledge) the measuring blocks etc.

Ok, I know a man who normally services my cars now, he has one.

We will try that route first 

Thanks

I do have a air con system diagram from my Skoda dealer for my vehicle. (attached)

I do not know what some of the numbers are called though.
