First let me say that you better have a VERY good MB diesel mechanic working on this car. In any event you have the 604.912 engine with what was called DFI(distributor type fuel injection)---that is important in relation to the faults

1227=injection pump distributor shaft position sensor(Y23/212)
0105=pressure sensor(B28)
1224=fuel quantity controller
1222=position sensor(R25/2)
1228=injection pump quantity stop
1630=drive authorization signal

There is a large and long test that covers all the detail of these items it is numbered 23 and you have to have the MB diagnostic software to test all the items.

However based upon what I have read and you mechanic developed your problem is----------the fuel injector pump!!!

I know you have a different Thanksgiving Holiday, but I wish you well on our Thanksgiving----Good Luck

Thanks, Plutoe! Happy Thanksgiving!

I hope you are not right and the problem will be something small. In the meanwhile I adopted my driving and the light very seldom coming up now. The car running nice, no smoking, etc...
On this printout what I got from the mechanic says "X431 DIAG Report" and "smartbox" .
Is this say anything to you?
Thank you!

Plutoe

That is the type of diagnostic tool that was used---it's a "Launch X431" a good tool for many type of cars, but I only do Mercedes diagnostics and therefore only use the DAS Xentry diagnostic software,WIS and EPC!!

istvan72

I guess I have no other choice than go to the dealer. The only problem I don't trust them much. Can they pinpoint the problem with their diagnostic software?
Thanks Plutoe, you are the only one who actually answered my post!

Plutoe

At this point I still think that you have alternatives to the dealer. You have to do your homework and find the indy MB diesel mechanic. Then of course if you don't want to do the homework---you have the dealer.

Like I said earlier, based on what you have said and reported I believe you have a bad injection pump, they are not cheap.

If I were you. I would start like you did get the faults read----clear all the faults----the run the car around for a couple of days and then have the faults read again----does 1227 come back----the you know you have a bad injection pump----Good Luck

istvan72

The only problem, I didn't find any Mercedes diesel mechanic. What I found was some mechanics who fix Mercedes too. When this mechanic checked my codes, I believe, he erased them and when I put the ignition back he checked again and the 1227 came back only. I can bring the car back to him as he fixes mercedes/bmw audi/vww but as we know he does not have the Xentry software.
btw yesterday I took apart the air intake to get close to the injection pump, checked the connection to the distributer shaft sensor, everything looks ok, no loose connection, no corrosion. Although the intake has has oil/ash/? deposits/dirt.

Plutoe

If you trust him, then I would let him provide you with a quote!

istvan72

that is what I gonna do. next week. thanks!

Hello Plutoe!
One more thing I noticed. I see air in the fuel line before and after the fuel filter (highest point in the fuel system) when the car sits for couple hours at least. There shouldn't be air,right? Is this air leaking to the system can create the problem? Thanks!

Plutoe

That is not true------(very hard to explain over the Internet)do not get side tracked at this point with the so called "California bubble scare" otherwise known as HS.

Proof= start your smoker and watch the fuel flow.

istvan72

ok, thanks!
There is no fuel injection shop in the area who could test/check out my pump as it was never in north America. Right now I'm checking Europe to get a rebuild pump. 1000+ euro.
Still so hard to believe I have to spend this much although the car runs fine (when the light is not up)
I also figured when the light comes up I don't even has to stop the engine just quickly take off and put back the ignition and the light disappears and running perfect again.

If it's only one part of the fuel pump causing the problem why not have a pump service company have a look . Could be cheaper.

There has to be Bosch servicing workshops all through Canada . They are in small towns here in Aus.

The above makes loads of sense----why not give it a try!!

istvan72

Believe me I phoned around.
As this model was never introduced to North America the Lucas shops (yes, it has a Lucas/Delphi pump) has no software to check, no fixture to put on the test bench and no matching electric connection to activate.
Yesterday I was talking with a guy in the best fuel injection place around here (authorized Bosch/Lucas/ etc place) he was very helpful, googled the pump for me to get the Lucas# but it is not even in his system.

Carsy

Sorry I could not help.

But I must ask why in hells name would MB use a Lucas pump in 1997. The Lucus in the 1999 Peugeot cannot have the seals renewed . Its a throw away job compared with the Bosch which is repairable.

Carsy

There is a chance I suppose that it is the 1227=injection pump distributor shaft position sensor(Y23/212) itself that is causing the problem.

What is the possibility of disconnecting the sensor & running the car.?

Is ther any down side to this as you are considering a new fuel pump.?

giuseppesalvato

had the same problem a few months back, I think it was the fuel pressure sensors on the high pressure fuel rail, either the rear one or the one at the front, never got the chance to find out as it cured itself, the car would just stop, it started again easy enough, this lasted for a couple of weeks, when i took it to independant mercedes mechanic, they could not replicate the fault, no fault code showed up on their Star machine, so no charge, write as rain ever since.

Plutoe

Although a good point,the previous post will confuse the OP as he does not have a CDI diesel, he has a mechanical pump very different than CDI which does not have fault 1227.

dieselguy220d

I've got the same problem with my Merc. Fuel dose meter going bad and distributer shaft position sensor's going bad too (read fault codes), only EPC lights up when I start after the glow plug light shuts off, not when i turn all power off (after pre-glowing) and then turn the key straight to start position. It doesn't smoke that bad, little bit of smoke coming out when accelerating hard. But that tells me somethig that the Lucas pump's going bad and needs to be replaced.

Also can you give a little info about these faults:

-Fault in CAN communication with traction system
-Clutch switch or starter lockout and reversing lamp switch
-receiving ECU
- brake assistant
- fuel type con. faulty

The machine called Reflex showed them like that, not any codes *bummer*. Do I need to get the car to the dealer and read the fault codes with STAR to get bettter view what's wrong with my car?
