kermeli · 05-23-2019, 03:08 AM

hello!

Went to the a/c maintenance because no cold air was coming from the vents. He tried to fill the system but it didnt, there was a leak.

It is behind the heatwall, at the bottom, near the windscreen fluid tank

Few pictures to help

it is apparently the number 2, but i dont know the part number. And it costs 255€ for a small piece of aluminium ffs.

appreciate alot for any help!!

I have the same car with the same part (64536927846) replaced 2 weeks ago. It leaked all the freon 4 years after I had the AC compressor replaced. I'm going to have to keep the car longer to amortize these costs.

#2 looks like it would be on the other side where the intake manifold is. it looks like the part is actually #3

edit:
part number is 64539151734
it runs from the condenser through that heat shield around the rear of the engine into the firewall

For €255 I’d be trying to fix the hole in the pipe with a blow torch and some brazing rod.
