What road noise is this, grinding or crunching noise? replace wheel bearing.

My friends car has the ABC so I don't know too much about Airmatic. Often an Airmatic Strut leak.
Are all four corners sinking similarly or is one more than the others?

if there's ride height problem, then a leak could be present.

if the pump is faulty or the valve is leaking (run time exceeded)... then it will shut off.

However I've heard that you can test for leaks at the top of the front struts with a small amount of water...you'll see it bubbling at any (broken) seal on top of the strut tower. (The car would have to be running...) It's pretty common on W220s. Among people I've heard this from are the techs at the dealer.

Try to visit this link http://www.automd.com/.../ to see a guide on how to replace your starter motor.

How thick is the glass on your benz? If its around 2-3 inches then you have the guard. It should also be bullet proof. Anyway, can you be more specific with the suspension problem you are having.

Good luck with your war

Try the 'How-To-Guides' feature this website on how to rebuild the strut inserts. You many also try the Bilstein website for more specific rebuild information. Basically, once the front struts are removed, you'll need to compress the coil spring to disassemble the strut assembly. Using a strut spring compressor to safely compress the coil spring, then remove the upper strut mount. Then, remove the spring. Next, loosen and remove the strut cartridge upper retaining cap. Then, remove the strut cartrige insert from the strut housing.

You can't, i bet you remove the battery cables prior to happened this. Only the dealer who has a code reader can activate your radio. In your owner's manual try to find the codes or contact your dealer to get the codes.

Typically, the shock absorbers and struts (front and rear) are worn out after around 60,000 miles or so - depending on several factors; type of driving, road conditions, suspension wear, among others.

If any "weird" electrical issues occur it is usually a ground. Bad connection on a ground or a moisture issue with a ground in a relay on relay module.

Crazy idea but maybe put the N10 module in a window or on porch for couple hours in the sunlight to dry it. I use a hairdryer but you can get it VERY hot - too hot for some components with the hairdryer.


I would check your ground to the hazard sw 1st though. - Take a 12volt light tester about $5 at any auto store - Connect the alligater clip to your key (your ign is usually a good ground) and touch the other side to the ground side (I believe the ground is brown) of the hazard switch - if its a ground issue the lite will go off. Then you know its a ground issue

Try the 'How-To-Guides' feature on this website for the control arm bushing replacement. Usually, once the control arm is removed from the vehicle, you can use a hydraulic press or bench vise to press out the old bushings and install the new ones. Be sure to apply a light lubricant, such as WD-40 or other spray to the outside surfaces of the new bushings to ease the press installation.

Have an auto parts store machine shop press them out and press the new ones in. To try to do this yourself would require many non-basic tools which you will not have. Air chisel and bushing drivers.

Possible wheel bearing failure. Raise the vehicle and try to move the wheel side to side and examine if there's an obvious clearance, spin the wheel to imitate the noise. If present, replace wheel bearing.

'Parameter steering' was a system which made low-speed driving easier by reducing the effort required to maneuver in speed-sensitive situations such as parking.

From Manufacturer: ThyssenKrupp Presta SteerTec GmbH

'Maximum safety thanks to parameter steering.
Speed-sensitive parameter steering from ThyssenKrupp Presta SteerTec makes for relaxed driving on long journeys and steep mountain roads while at the same time providing easy maneuvering in town.

Parameter steering with variable centering from ThyssenKrupp Presta SteerTec meets the highest safety and comfort requirements.

An electrical sensor continuously measures the car’s speed and controls a special valve which opens steplessly according to a specific characteristic depending on speed to release the required amount of oil to a hydraulic system which boosts steering feel.

Parameter steering has proved successful as an optional extra in various Mercedes-Benz models. True to the motto “only the best is good enough”, our developers have taken parameter steering to the next level of technical achievement – called parameter-setting with variable centering. The driver feels this in terms of a palpable gain in driving stability and safety. Unwanted steering movements are kept to a minimum while the vehicle remains firmly under control.'
