    Got an air con leak on low pressure side..... doesn’t hold vacuum.

    any ideas? Going to replace seals first.

    condenser was replaced last year with ECP EIS Part (222440611) from memory.

    Replaced the following seals and performing another vacuum test.


    4E0 260 749 A
    3D0 260 749 C
    8E0 260 749 C

    The 8E0 I removed was damaged so hopefully that was the problem. A small piece was missing from the seal.

    We have trouble with a Golf 5 GTI last week, in the end we found debris from the compressor in the expansion valve, you can store meat in there now it is so cold.

    It’s passed the vacuum test and been injected with r134a. It gets cold but not down to 8 degrees centigrade when we use a probe in the dash vents. It’s probably about 11/12 it goes down a bit up one acceleration but doesn’t reach 8.

    weak pump?

    where is the expansion valve on the Mk5 BAG engine?

    If you have any pictures or diagrams that would be great.

    thanks

    Air con is working.

    but still got fault codes on ODIS.

    the ECON light / button doesn’t come on when I press it. It’s constantly out the LED. But does appear to turn compressor ON and OFF as the air does go cold and then hot when pressed again.

    If it has a Sanden compressor they are very problematic, we insist on Denso new, not recon. The expansion valve is the coupling on the bulkhead to the evaporator. Genuine they are insane money (hundreds) but Febi list them in the tens but have no stock! ECP have Hella for a good price.

    I’ll take a look but not sure is the labels are still on it.

    Ive seen you can replace the N280 valve or that not worth doing?


    Do I need to replace both compressor and expansion valve? With those codes above?

    00898 and 00229


    can find Mahle expansion valve on ECP 234440080

    You need to replace the compressor, to satisfy the warranty you MUST replace the receiver drier therefore complete condenser. The Mahle expansion valve is good.

    Is the complete evaporator the condenser? Or am I getting confused? I replaced the condenser with ECP 222440611

    The receiver drier is part of the condenser, we used that same unit as you last week but I think to fulfil the warranty you may have to do it again or risk it. The evaporator is in the heater box and evil work to change
