W220 S320
Rev Counter Jump with AC on - Cliff Hanger...
Hello all,

Greetings from Australia.

I own a W220 and just tested a 1990 W126 420SEL with 242,000km on the clock as a weekend car.

Car drives well with AC off. (suprised how much smoother it is compare to my S320!)

With AC On, it makes funny noises, and the Rev Counter jumps up and down, even the car is in idle.

I am going to make a decision if i should get it. Just checking if anyone should have any insight re this?

Thanks
Nelson
