98 320 ml/ Toyota 7seat verso sr/ mercedes sprinter/
Hi guy's. Please excuse my pure ignorance on this matter but I need some help. 1st I have just got a 1998 320ml for my wife to use for the winter, I did not pay anything for the vehicle. I just fitted discs and pads all round and when on the ramp my mechanic was moving the wheels. This is where my confusion begins. He moved the rear wheel and only the opposite wheel moved and not the front. I thought this model was permanent 4x4meaning surly the front wheels would rotate as well. This made me investigate more after the brakes fitting. I tried to engage low ratio by neutral brake low range. light blinked 3 times then off. Also tried turning traction control off but no light on dash like my mercedes sprinter. Can anyone shed any light or am I just thick. (I am with 4wd cars)
 
the flashing low range light will be a duff low range motor. Common issue.

The triangle should illuminate in the centre of the speedo when the esp is off. Does this happen?
 
Hi. The yellow triangle in the centre of the dash does not come on. I have a similar system in my 04 sprinter and would expect it to light up the same way.
 
It should. I suspect there is a fault with the system. Does the ESP/BAS light come on when the ignition lights are on (key in pos two)
 
I have just tried this all lights light up and go out except from ETS from what I can see which does not light up?
 
Ok, it needs to be plugged into a Star (MB diag equipment) to see if the switch values are recognised by the control unit. The "ESP off" switch maybe duff.
 
Thanks Olly. Will take it to my local garage to have it checked out on their machine, was just a bit surprised to find it might have a problem as it drives like a dream
 
They will need a Star. Are they a MB specialist?
