electronic diesel control (EDC) light is on!!
Hi every body,
since yesterday during a silly cleaning job in my 290 gdt as I touch with a screw driver a black cable under the preheat relau and due to a circuit the EDC light came on. The car is running without any problems - so far (I hope!!). Any advice how I could reset the light?
Cheers Angelos
The handbook states
Warning Lamp - Electronic Diesel Control
"If this warning lamp lights up in the cluster when the engine is running, then there is a fault in the fuel injection system. Full engine output is no longer available"
I would take it to my local Merc commercial agent. They will put it on there computer and hopefully tell you what the fault is. I use the commercial garage as they tend to be more converse with the 290 unit then the car division. Also a lot cheaper.
You should also find any competent general commercial garage should be able to check it for you, as most now have fault diagnostic equipment. The ECU is almost the same as the one used in the Merc Sprinter.
The most common fault, which will put you engine in limp home mode, is when the ITC light comes on. Topping up the intercooler usually cures this.
Odd you mention those couple of points Twomogs
( i ) The Commercial Merc dealers over here were very helpful and wanted to help -- but could not apparently bring the 290 "G" Wagen details up on their system, though I see where you are coming from, the 290 being a commercial varient.
( ii ) when I got my radiator exchanged, the ITC light was on on the way home but the van drove as normal -- turned out the intercooler reservoir was empty though when I looked ITC up in the handbook at home.
Cheers

Dear fellows after the visit to the local MB deaker and when I erased the memory everything now is ok.
Thanks for advises, Angelos
