S550

I suggest having a mechanic ride with you and see if it is one of the rear tires or the bearings are noisey. I suspect the bearing is noisey unles noise started right after the new tires were installed.

A fault with a fuse would more likely result in non operation rather than continuous operation. ECM's rarely go bad, indeed of the ones "claimed" to be bad, that is of those sent in as warranty returns, based on surveys...

Hi there - there is a flexible coupling in the driveshaft that connects the transmission to the driveshaft called a "flex disk" or "guibo". This disk is essentially a rubber and fiber donut that flexes as it transmits power, and...

Hello - unfortunately, that is not a service YourMechanic can offer at this time. Thanks for thinking of us though!

Hi there. Check the switch to the hazard lights and see if the switch got stuck. Sometimes the switch tends to stick and make the hazard lights stay on. If the switch is working, then the contacts in the switch...

Assuming you are talking about the valve body control module, the answer is typically yes. However, it depends on the situation and what specifically is wrong with your transmission. The Mercedes transmission in this generation is a very solid transmission...

As the vehicle ages, the strut pulse dampeners on the pump may lose some of their gas pressure and require replacement. As far as the ride height, it could be due to the suspension in the right rear being low...

Hello. The most common cause of this is a failure in the drive shaft coupling. The coupling begins to fail and this occurs. I would have this checked by a shop that specializes in this as it can be difficult...

Hello - except for the Mercedes factory Service Manual/DVDs, the usual sources of quality aftermarket service manuals (i.e. Bentley) are bare on this one. Haynes/Chiltons don't yet cover anything this new either, certainly not for S-class models. Your best bet...

You have three very nice choices in front of you and I am sure you know of the amazing reputation Mercedes has with respect to these particular models. The AMG model comes with slightly more horsepower and a bit more...

As you may know, there are very few things (if any) that either of these cars do not have (assuming we are NOT including the S63 Coupe in this comparison, which is a much more extreme version of the S...

If you start the 2007 Mercedes-Benz S550 using the keyless go system and the vehicle is acting erratic, then it may be due to this module being erratic from the battery voltage dropping below a certain level and causing it...

This suspension system on your vehicle uses hydraulic fluid that supports the vehicle and different valves to control the active suspension. The right front unit showing any signs of leakage on the boot should be replaced. This vehicle may be...
