Hi all,
Great forum!!!
I need help with my ML320 2000, I have only had the car for about 3 months and it has let me down at least five times so far, however I'm unable to find the problem.
The car would just turn off while I'm driving or when I'm stopped at the traffic lights. All the lights on the dash would come on, as if the ignition is on. When I try to restart the car, it would crank fine but fails to start. If left alone for about 5 - 25 mintues it would start first go. Everytime this happened I called my roadside assistance, but it always starts before or when they arrive, they check a few things and tell me that they can't see anything wrong.
I took the car to Eurotech autos, he plugged into a diagnostics tool and advised that no error has been logged.
Any help is appreciated, any suggestions that I can try to isolate, or diagnose this issue whithout taking it to a dealer....Thank you kindly.

This has just happened again, while driving in 30 degree heat, the car turned off while driving 5 minutes into my journey. Tried restarting car, it cranks ok, but no start, open the bonnet, there's a sensor on the front of the engine on the left hand side (if you're looking from the front of the car). wanted to put water to cool off the front of motor or around where sensor is. unable to find tap. left bonnet open for 2 minutes, closed bonnet and tried restarting again, started first go. Should I attempt to cool off the front of motor with water, or can I get a spray of some sort, what is that sensor on the front of motor?


Thanx.

Try the SEARCH feature on crank "flywheel sensor". That is a commom problem on the M112/113 engines in most 1998 & later cars!

List price is around $100 & takes less than an hour to install.

Fuel pumps can cause tha same results!

Is this the same part as the crankshaft position sensor (CPS)?? Because I found DIY instrauction on this site and I'm willing to give it a go myself.....

Yes it is. It's on the rear of the engine where the engine mates with the tranny on the driver's side. There are 2 types. Be sure to get the correct one.

I found the related item at my local Merc dealer, They identified the part I need by taking down my VIN Chassis number. The cost is AU$140.00
I will pick it up tomorrow and replace it myself.
If this doesn't solve the problem, I believe I should be looking at replacing the Fuel pump!!!Right?


Thanx.
