The abc light has come on. The dealer is estimating the repair cost at $12,000.

Stay away from this unit at all cost.

In addition, the sbc unit is a problem and repair cost is around $2200.00.
I have a lot of cars but none so difficult and tiring at the same time as good as cl. My favorite cl500 is 2001 and he had a problem with ABC pump so I replaced the new (red ABC car too low and doesnt rise). I replaced it my self.
Leaking ABC PUMP deteriorated air conditioning compressor so i also replaced it myself.
Subsequently leaked to the left front shock absorber, so I poured the liquid against leakage power steering systems and leak stoped.
The car can be driven but the front left shock absorber delayed rise when just start the car.
I will drive more and we will see

One of (3) short lines running under the (firewall on drivers side)from a block is leaking. Tech will clean a recharge system to determine which line/lines are bad. May have to replace all (3) due to fluid saturation. Lines will run about $169.00 ea., fluid (2 liters) bleed system & labor $750.00. Also got quote on ABC pump replacement. Rebuilt from Mercedes, New Pump, Fluid (10 Liters), bleed system & Labor (6 hrs) Ttl - $1,950.00
ON Oct 1 2012,the line blow up,all the fluid leaking out,$1700 to replace the line, stay away from this car
I have spent thousands and it still drops after not driving a day. I am told I need new front shocks- more $$$$
Replace the pump and flush the fluids. Dealer wanted $3700, found an outside mechanic to do it for $2500.
First was front driver site dropping about 3-4 inches. They replaced the valve at about $3500.oo cost. Then a few weeks later, the whole driver site was dropped (front and back). Now they tell me they need to replace the other valve at $3500.00. I am notr sure if it will be fixed.
