replaced brake lights crankshaft position sensor and last
the last sensor replaced is lateral acceleration sensor
all the bas esp lights no longer appear however now my new battery light comes on sometimes and then goes off should I see if battery is any good ?

If battery light comes up it means your alternator is not charging as it should. While the car is running measure the battery terminals. You must have around 14,2v. If it is less then you have a problem with alternator. Usually it is the voltage regulator on the alternator.
While the car is of measure the terminals , you must have 12+ volts. If it is low most probably your battery is dying......

ML500 with same lights
I have this very same problem and the codes showing on my scanner are:
P200F G3/4 (Right 02 Sensor, before TWC[KAT]) : Short circuit in the signal line (P0131)
P2068 Electronic Transmission ECU - N15/3 ERROR STORED In COMPONENT
Anyone any ideas please its the wifes car and dont want her to drive it with the kids in if its going to go again

I have the same problem. 2000 ML 430 with the 3 lights on (no brake light) BAS/ESP, ETS and ABS. Replaced the brake light switch by recall, was hoping that would fix it since it helped many others.
Got it scanned and I was getting an ABS pump malfunction code. I did some testing on my own but not really sure where to go from here?
1.) I disassembled the ABS control module and pump. Tested the module for power and ground continuity from the plug to the 2 pins that run the pump, it was ok.
2.) Took the pump and hard wired it to the battery, pump runs fine.
3.) Took the pump and hard wired to the ABS fuse, runs fine.
4.) Took the pump and hard wired to the harness that plugs into the module and the pump would NOT run?
5.) Measured the voltage at the harness where it plugs into the module and it is around 9v instead of 12.
Could my harness be bad? I checked continuity from the fuse to the harness and it was ok. I don't see the harness grounding out anywhere.
Something wrong with my battery? It checks out fine otherwise though..
I also tried swapping relays with another that was similar and same problem.
Does anyone know what is between the fuse and the harness to the control module? AT this point I'm thinking of just wiring a switch in the car to drive the pump directly.. lol.

How can a piece of wire drop so many volts without melting ?!?!? There MUST be something else inside the fuse box between the ABS pump fuse and the pin for plug 11 (two wires) which provides the power to the ABS pump plug via the short harness ??
Did you ever find a solution ???
I am about to cut the wire at the ABS pump plug and connect +12V to it from something else that is powered whenever the ignition is turned on !!!

I am fighting EXACTLY this issue with my 2001 ML55 .... I can't understand why the voltage drops from +12.5V on the ABS pump fuse and at the ABS pump relay to only +9V at the other end of the short wiring harness on the plug going into the ABS pump (when disconnected from the pump, so that can't be dragging it down), and this red power cable (from the ABS pump plug to plug 11 (two wires only) going into the fuse box measures zero resistance with a meter.

When you are asking for help you must supply some info. that is essential to helping you.
In the future you must tell us what fuse # you are testing and what relay # you are swapping.
With that said, you are confused as to what fuse #27 (assuming this is the fuse you are referring to) does. This fuse supplies voltage via two RED wires to the ABS Control Module which is located in the fuse box. It has nothing at all to do with supplying voltage to the RED wire at the ABS Pump.
Relay K25 is unfused and voltage is supplied to the relay from the fuse box and the ABS Control Module. When a panic stop is required, the ABS Module senses this and sends a ground signal to the relay which closes the relay and then powers up the RED wire at the ABS Pump Motor.
You must get, or borrow a scanner that is able to read ABS "C" codes to determine what is wrong with the system. Just look at all the possibilities.
Before you do anything, remove relay K25 and then introduce 12v from the battery to the RED wire at the two wire connector at the pump. If the pump runs smoothly then there is nothing wrong with the pump and the problem lies elsewhere, and codes must be read.
If it doesn't run or runs sporadically then the brushes in the pump motor are worn.

Toyota supra, ml270
ML 270 cdi. No Warning light, abs, bas/esp,
Hello,
I am new to the forum after buying my first Mercedes, I have bought a 2001 ML 270 Cdi. Bought it 10 days ago and have noticed today that when i turn on the ignition i get no warning lights.
Abs
Triangle warning light
Bas/ esp
Engine diagnostic light
Low range.
All of these did work when i bought the car but nothing now, i have read on the forum about them staying on but not that they don't actually illuminate.
Any help would be grateful

Ml270 warning lights.
Mystery solved on why they do not work!
All of the warning light bulbs had been removed, i guess in my haste to drive it away and that i had seen them when i paid the deposit i had not given it a second look until i was looking up about the fog lights.
Lesson learnt.

I have a 01 ML320. I start the suv and everything is fine. Check engine light stays on but otherwise runs great. After runing for 7 minutes and 45 seconds there are several beeps and the BAS/ESP, 4-ETS+, ABS, and Brake Light all come on. The speed odometer, odometer, and sometimes fuel gauge stop working. It will stay in witchever forward gear it is in (ie; if its in 3rd when this happends, even if i stop and put it in reverse, back up, then put it back in Drive, even though it will say its in D the transmission would still be in 3rd. or whatever it was when this happend) Sometimes it will run rough, other times it will go like a raped ape. Now hears the kicker. All i have to do is restart the car and everything is fine. All lights go out but the check engine light. Sometime the check engine light goes off. Of course, after runing for 7 minutes and 45 second it starts beeping again, and the BAS/ESP, 4-ETS+, ABS, and Brake light come on again, etc. My local dealer is stumped. Anyone got any ideas? the one constant is`the time from start to error. I would be greatful for any ideas.
Re-starting every 7.5 minutes is getting old. :~(`

Has anyone found a solution? There are a lot of responses on this thread but they are having different problems than what we are (problems with lights being on but not only after driving for 7 mins). Please help!!

Check your Brake Fluid level and also make sure the Parking Brake is fully retracted.
Low brake fluid could also indicate that you brake pads are worn down.
If there is no problem with the level or the parking brake, you must have the "C" codes read in the ESP/Traction Control Module.

I would love to hear if anyone has the washer fluid issues, and if changing the relay with that issue present fixes the problem

The issue with the washer fluid is that the reservoir leaks on the ABS module. Fixing the leak, opening & drying & making sure there is no corrosion of the electrical connector to the ABS module normally can fix the issue.
If your problem is due to a leaking reservoir changing relays will not help.

now this fan is run by a TOY 12v Johnson motor which will no doubt be burned out which in turn has caused something in the ESP computer to overheat and burn out thus going in to limp mode after about 7 minutes
the ESP computer will have to be replaced or fixed i bought one from the wreckers in Perth Western Australia for AUD$400 but in the meantime the YAW RATE SENSOR WENT as well
i was quoted over AUD$2000.00 from the local Mercedes dealer bought one from the US for AUD$650.00 delivered[original] Merc is now sold
good luck if you need any more info email me
regards

Ml320
Same lights 7 mins gear stuck
Hello I have this problem now for a few days. Swapped out the tires to ensure proper traction and brakes to hopefully clear these codes but nothing fixed it.
Please has anyone taken theirs to Check the c codes for this issue? Already spent 300 in diag with no results...

If you have spend $300-00 on diagnostics, surely you must have the codes written down. Post them. If not have the car scanned with a pro level scanner & post the codes

OKay- called the shop back and they gave me the following codes and notes they had for each one - hope this helps...
P0720 - OUTPUT SIGNAL
P0500 - VEHICLE SPEED SENSOR A LEFT FRONT BACK LEFT REAR
P0600 - ESP
UC1025 - DSH LIGHT - TRASMISSION CODES 134, 135, 148
I still have all the lights on after ~7 mins driving and gear locks in whatever it was in at that point... please help!
