that seems to be enough detail

i want to know how to burn out what do you do i don't know if you have to push the brake or put the e-brake on

the car runs great going forward but the car wont go in reverse

my mirrors don't adjust. My driver side seats don't adjust. My driver side window and both rear windows don't work

its a 2000 S500

the car is running fine except for the check engine light being on. Can i continue to drive it?

The car has automatic door and trunk closing

its under the dash

When I slow down.

Drive side window did not lift evenly and was stuck in that position for several days. Managed to lift front of window while bumping window button up and down until window was fully raised. But noticed, it was too high and door would not close properly. Managed to lower window enough for door to close. Now when door is closed, auto lifting of window doesn't close the window tightly, leaving a 1/4" gap between window and window seal.

Over the past several months I have noticed a slight clicking sound coming from rear of car. Only occurs when car is moving forward at lower speeds, higher speeds, sound is inaudible. I have had several mechanics look and listen for it, none of them have been able to locate the origin of clicking sound. According the mechanics, it isn't shocks although, one shock bushing was replace as a possible cause two weeks ago, not the problem, $300.00 later.

Heated air is coming from driver side vent when ac is on for the rest of the car. When I close left driver vent, hot air begins to come from driver side center vent. closing that vent hot air moves to passenger side vents. Climate control is not balancing heating and cooling.

Passenger seat has had this problem for several months. Driver side just began two days ago. I also noticed the driver seat has lost its memory and will not return to pre-programmed setting.

My 1999 Mercedes s500 noisy fuel pump was replaced but the new one is making the same loud wining noise when it gets hot, they also replaced the fuel filter as well. It's it the type of manufactor pump being used or is there another part somewhere in there that kills the noise? What helps to clean up maybe carbon build up? My macahic poured some engine cleaner some kind of solvent cleaner and told me to drive it over the weekend, then I went in for a oil change. But still have the ticking noise. It's not as loud and it comes and go now. Meinly at cool start it's fine but as I drive around town it comes. If I take it out on the open highway and open her up it sometimes go away. Ugh frustrated.....

Just noted on 160,000 miles.

Mechanics are getting too expensive.lol

crank positioning sensor

how do you stop the pump from pumping the fluid from back there

I need to test the power to the fuel pump and test the fuel pump to assure it is working. How do I get to it? Do I have to drop the gas tank or can I get to it from the floor board? It's a 2000 mercedes sedan S500.

I have to manually push down and up on all the doors to lock and open, the driver door I have to use the key to open and look. The doors do slowly close with that close assist feature but the trunk has to be slam shut. Fuses are all ok. I can hear the closing assist pump make a little Hiss sound when the doors close the rest of the way in by them selves. Also if I close a door and sit in the car real faint I can hear the motor to the PSE pump come on. The remote just tunes the antitheft system on and off. Can someone please help me out here I would really appreciate it thanks...

Can I get to the fuel pump for a 2000 Mercedes sedan S500 without dropping the gas tank? Can I change it by going thru the floorboard instead?

replaced all electrical relays under backseat and car is NOT getting fuel. How and where do u test the sensor to the fuel pump?

after replacing the relays under backseat again bc there was water in the relay boxes again, (don't know why), now the fuel is not getting to the engine. The fuel pump relay does work and so does the fuel pump. What would I troubleshoot next.

vehicle body is practically sitting on tires

I replaced the fuel system relay and there's still no fuel getting to the engine. What is my next step to troubleshoot this problem?
