I bought my 55 plate S320 cdi knowing that it needed a bit of work to make it roadworthy again, there was a number plate light out that I have determined is a wiring fault, the exhaust is blowing slightly and the interior is very grubby. It was blowing stinky diesel smoke and knocking slightly so I knew that an injector or two was probably in need of replacement, and it has an EL.Power EPC fault which could be injector / fuel pressure related.
With the better spring weather upon us I thought I’d better get the bonnet up and have a look at the injectors, with paper and pencil I took down the part numbers on the injectors. I was initially happy to find that I didn’t have any numbers in circles so that meant I didn’t have to have any replacement injectors coded to the car. This happiness soon disappeared when I looked up my car on the epc and found that the injectors that are fitted are for an earlier model S Class and other Mercedes models, the Mercedes part number of the injectors that are fitted is A6130700587 and the Bosch number is 0445110096 but should be A6480700287 and 0445110176.
My meagre understanding is, and I am prepared to be proved wrong, is that the later facelifted cars like mine had a higher fuel operating pressure compared to the older cars and this leads me to believe that’s why the injectors currently fitted are malfunctioning. The current symptoms suggests that one or more injectors are leaking down too much and causing the car to smoke and run a bit uneven.
My question is to the collective wisdom on this fine forum is, are the injectors that are currently fitted suitable for my model and year? If so I’ll get them all refurbished but if not then I’ll have to start looking around for replacements.
I once read a thread somewhere on the Internet that had a list of injector part numbers that were suitable for W220s of all years but for the life of me I can’t find it again, but what I do remember from that thread was some injectors on that list started with A613.
Any help will be gratefully received.
Regards
