Dear experts,
I've gone through lots of topics and already found some solutions e.g. (windscreen wiper is sticking)
But the car has a few problems I'd wish to be solved.
1. There is a mechanical noise (I'd say even roar) from the right front wheel but it appears only whenI take a left corner +speed is over 40km/h or when the suspension got wet (puddle is enough to produce it)
2.Plenty of topics regarding sparkplugs but nothing that could help me to choosea right ones for L6 engine and maybe some guidelines how to install them.
3.There are holes (small speakers I assume) right above the front seats between lamps of interior illumination. They produce a strange, crackling sound sometimes.
To get rid of which I have to restart the engine sometimes but it may disappear in few minutes (just a matter of patience)
4.When the heater/AC fan is running and acceleration isa bit hard there is sourishburned dust odor in the car.

Thanks in advance.

1. Not sure? Maybe a bad wheel bearing?
2. I would get Bosch as far as which ones you need just ask a auto parts store. I have platinum +2 in my 560sel.
3. My guess is they are tweeters and they are blown.
4. Well i would think that it might be the cabin air filter might need replacing.

 

Do you have an idea what kind of ABS sensor used in MB C280. Are they *Hole effect sensors* (which basically magnets) or *pinion drive* (which could produce mechanical noise)
Why the tweeters go on? What is their purpose?
