Hi All

My idle does not seem to compensate when the compressor kicks in and cause the car to shudder before the idle climbs up again.

I am testing the KLIMA relay at pin 87Z and I get 0.15-0.16 V (compressor off/on). I tested the KLIMA on the bench with terminals 15/32 (12V/gnd) and activating terminal KL (via gnd). Am I testing it correctly and is 87Z supposed to show 12V with compressor on?

KLIMA p/n is 002 545 12 05

Regards
Andrew
