2005 C180 Kompressor idle problem.

[Maz]

Afternoon Guys

I have a 2005 C180K In stock which hunts at idle, engine light is also on.

Error code refered to a HOT FILM MAF Problem, so we replaced the MAF Sensor with a new OE Part and the fault hasn't gone away and still hunts on idle!

This car also has squeaky rear suspension, what can be done to make it unsqueaky?

Thanks

Oh and one of the 02 sensors rear 19.72mv which the other fluctuates whilst reving between 1500-4000mv.

Could this be the cause?

Thanks
