The main battery was replaced 3 years ago, could it be the small battery beside it?

Hours after I came home, my car has a loud horn like sound coming from under the hood. Theres a big black ball looking thing on the right hand side close to the dashboard that stops the noise when pressed in. What is this and how do we shut it off?

Just bought a ML500 from a car dealer, can hear the drive shaft, not bad bad I guess can just hear it wen driving.
Car also nudges forward sometimes when I stopped & waiting, my foot is on the brake & its in Drive, what is that?..
Also a clunk happens at times when gear change or go to accelarate.
Reverse is quite hard sometimes wen I go to accelerate, have to press the foot peddle at least half down to get movement. If anyone can enlighten me in these things, would greatly help, Thanks Sonya

The buzzing sound lasts for about 2min then goes off, was told air shocks adjusting.

I have the brake light repair kit already installed and still not working I replaced the turn signal bulb socket and light bulb as well.

Replace Sam module 1 month ago n rear windows will not go down n head lamps will not work

I am replacing the brake pressure sensor to stop the bas esp light from coming on.

wan to buy a fairly used transmission for my ml500 mercedes

when driving slow speed my bas esp light comes on thin my brakes lock up why i am brakes driving

The dashboard doesn't light up, and the gauges don't move... So I'm wondering if it's quite possibly a "Fuse box issue", or maybe a "battery" issue (but it's DEFINITELY an electrical issue)

while driving cruise control stopped working. got home, parked car, went to put in garage later and now car won't go into gear. esp light came on several days ago. but went off.

Last week I noticed my air didn't seem to be working as it usually does. Then the other night I noticed my windows were very fogged over when they shouldn't have been. Today I noticed why they were foggy, the ac is blowing on the windshield. The setting are set to blow out the front facing vents. Also at one point the air wouldn't blow at all. Then just can back on a while later. It has a new fan that was put in this past summer (June sometime).

I HAVE ALLREADY INSTALLED A NEW THROTTLE PEDAL SENSOR.

Recently purchased 2006 ml500 with low miles. Rear suspension seams to "bounce" 3-4 times after every bump in the road.

The fan was recently replaced

It was running fine, now it's making a ticking sound and had slow acceleration.

I have been having lack of acceleration.. first i had all coil packs wires and spark plugs changed. New fuel pump. New crankshaft position sensor..n last my converters checked n new pipes. Nothing has changed this problem... drive for a good 15 minutes then the lacking start floor it and nothing happens.... i have to search for a good acceleration in pedal someone help please.

The horn blowing problem developed after having the vehicle serviced and new brakes installed. It was returned to the dealer to diagnose this and a problem with the brake wear light and coolant light illuminating and they replaced a faulty brake sensor & tested the coolant system for leaks finding nothing. We were told they took apart the horn assembly but after picking up the vehicle and driving less than 1/4 mile & coming to a stop, the horn blew and then did it again during a right turn. So far the brake and coolant lights are still off, we're keeping our fingers crossed on both these issues but frustrated with the horn because it could cause problems in traffic or distract other drivers. FYI the vehicle has been at a MB dealer 2 weeks out of the past 3 weeks to address these problems.

I looked in the fuse box under the hood and there is no listing for it, also looked in the passenger side kick panel, no listing for it there either.

Its hard to explain, but I almost thought it was in the drive train at first, but that's not the case. its like it's out of tune when i accelerate. not missing or anything but just dull.

If i purchase a key online can the dealer cut and program the new key at what cost???
