Air-con compressor

[LivingMudFish]

Hi all,

New to the forum. I'm servicing the air-con on a Touran. Normal air-con pressure should be 10bar high side 2bar low side however both sides are 4bar which points to compressor failure (usually).

Changed compressor and still displaying 4bar on both high & low sides.

Has anyone got any ideas where I should go from here.

Thanks

Ben
