Hi, my 1997 310D has the limp-home syndrome, with the check engine light not lit. We have checked most things suggested on this Forum, and wonder if anyone can help with these questions:
1 Please can anyone post a key of which fuse does what, including the 30A one under the seat?
2 I have traced all the vacuum pipes, all is clear except for a hard black one that comes from the EGR solenoid, across the engine bay, through the bulkhead on the left and ends under the glovebox. The other 2 pipes on the solenoid are the vacuum supply from the Y pice and the rubber one to the EGR valve diaphragm. Should there be anything on th end of this pipe, or is it there just to supply clean air when the EGR valve is operated?
3 What should the resistance of the coil in the No.1 injector be, or is there another way of checking it?
Finally, where can I pick up another injector cheap?

Thanks, Alan

Hi Malcolm, the VIN is WDB9034122P685032. We found what the blown 30A fuse does by looking at my 308 - it feeds the heater blower - but information about all the others would be useful, thanks.

As an update, we think we have mended the needle lift sensor injector, which was open circuit. We removed the metal strap and plastic cover from where the wires enter and found two soldered connections, the wire to one of them was broken so we re-soldered it and held the plastic cover in with a cable tie and Araldite. I bought a U581 cheapo OBD2 reader and Sprinter adapter, which while it will not display codes does seem to clear them briefly, performance is restored- but drops off if we disconnnect the reader. I still suspect the injector, it shows a resistance of 17K, not 95 ohms as someone else suggested.

Thanks, Alan

how did you get on?

I'm still looking for a code reader that will read these codes I tried a U381 which did't do anything.

If the needle lifer sesnor is below 70ohms it's not working properly(I tihink),Try a local garage with a snap on reader to read codes otherwise your stabbing in the dark.The 310d/312d can only store 10 codes at a time so it's worth clearing them then driving it again to see what pops up.

Thanks Loz, I'm glad in a way that the U381 didn't work either, I was worried I had wasted the exta for the 581. I took the injector to 3 dealers but none of them could tell me what the resistance should be, one specialist checked the break pressure etc but had no idea about the wires. Looking at different forums I've also seen 95 and 950 ohms suggested for the correct value. I did wonder if perhaps it's not a simple coil but a piezzo transducer, or a semiconductor like the MAP sensor, that would make simple resistance measurements less meaningful. If I were a dealer, of course, I could replace the thing (at customer's expense, £400 quoted by the Merc dealer) and see if it was any better. It does seem odd that with all the computer power in the ECU and the reader I can't get an answer to a simple question.... The list of things wrong with my ebay van now includes oil in the water, apparently most likely to be due to a faulty oil cooler, and the EGR valve has had both pipes crimped off. The diaphragm has a hole in so I can't reconnect the vacuum line to it. Will I ever get it on the road?

There isn't water or corroded terminals in the black bag which is attached to the battery casing is there?
