Why does my 2001 mercedes ml 320 rear end sway on wet surfaces

SOURCE: mercedes ML 320 1998. My horn does not work

About four things to do, first check voltage at horn with key on and button pressed. If voltage there try moving the small gap screw back and fourth a few times. If that doen't work replace horn. If no voltage check fuse and horn relay, you should be able to hear the relay click when you push the horn button, If not and fuse is ok. Switch relay out with another on on the car. If that doesn't fix it check the horn button for continuity.

Go to advance auto or auto zone and have the do a trouble code read ( it is free).
The plug is located under the drivers side dash to the left of the brake pedal.
Press the esp off button on the dash and see if ithas an effect. on acceleration

Next I would try this it is expensive.
If it feels like it is bogged down when you first start to acceleratewill only creep about 10 to 20mph it may be the mass flow sensor located between the air filter and the throttle body. It has an electrical connection. Sand eats them up and it is a common item about $200.

First you need to see if the remote central locking is working. It sounds like your transponder(key) is un synchronized. Even if the central locking is working there is a d.a.s.(driver authorization problem). Try your other key if you have one. There is a way to resynch the key w/o a factory scan tool but you have to follow the directions exactly and be quick. Point key at door receptor.( grab handle area) Hold the lock button down and press the unlock button 5 times in 10 seconds while holding down the lock button. hold the lock button down the entire 10 seconds even if you've hit the button 5 times. after the 10 seconds is up release and hit the lock button again. The d.a.s. system shuts off your fuel pump when their is an authorization error. It is a common problem in 98 and 99 ml's. Your owner's manual tells you how to resynch the key if my description is difficult to follow. Hopefully I have been helpful

Take your car to an independent Mercedes Benz Mechanic Let your dealer know you will no longer be using him for you cars service.
The SRS is for your airbag system and is unable to deploy on a low battery have your NEW mechanic reset this when your battery is charged

You either have to replace the battery in your key fob or have it reprogrammed. Verify this by trying the second key, if you have it. AAA told me that you can reprogram it by leaving it in the ignition, with the key turned to the first position, overnight. I haven't tried it.
