SC-C230

My wifes E55-daily driver has hit 180,000 & I decided to do some maintenance. I did stock replacement plugs,Magnacore wires,valve cover gaskets,TB gasket & surge tank gaskets.
My question is should I replace the injectors? Its a 2004 & with the miles-I think its due.
Dont want to have to get a tune to run bigger injectors.Just want stock.
Should I put new stock 2004 or go with 2006 part # 1130780123 which is the same as Bosch 0280156304??

Best place to buy them?

03-06 E55 has the same injectors. Wherever you can get new injectors CHEAPEST you should purchase them, BOSH parts retailer or MBZ parts retailer. Why not have someone test/clean them?

I think I've read somewhere that the 2006 e55 has bigger injectors ...

SC-C230

Just figured with 180,000 them - thats a lot of pulsing. Just replace with new.
Cleaning old & really tired injectors may not be the best decision?

SC-C230

Me too.
But not bigger-just a better design?

biggking

An injector has one job really, open and close. If it is tested and in working condition why replace it? I remember a sponsor here tested for flow rate vs stock specs and had some sort of cleaning solution. Just offering another solution vs spending $100s of necessary dollars. If you want to mod or upgrade it would be a different story.

Total myth. Would def like input on this from others.

Opening/closing for almost 11 years & 180,000 is a lot of use. Im sure failures occur with less mileage. I would assume they can't last for ever
Not really looking for a debate-they're old & i'm not going to send them out to get tested or cleaned-just want to pick up a set & replace them.

Just trying to get the correct info on what to buy & where.

No worries just def trying to keep you open to new ideas. If you purchase new injectors again, cheapest price would be ideal. You seem to have both part numbers and bosh numbers. Do some homework!

Whole thread is wack.

Stock 2003-2006 E55 AMG injectors are the SAME in bosh's injector handbook p/n 0280156072 which translates to mbz # 1130780123 or 1120780349 with a flow rate of 397cc.

Stock 2005-2006 Crossfire SRT6/2002-2004 SLK32/2002-2004 C32 injectors are the SAME in bosh's injector handbook p/n 0280156072 which translates to mbz # 1130780123 or 1120780349 with a flow rate of 397cc.

Meaning the injectors are the same. I also have chrysler numbers if you want them and they changed it about a dozen or so times. Ask and you shall receive.

Also the thread mentions SRT8 injectors and those are completely different, I am unable to locate any info on them. Will do some more research in the morning. (edit: just looked at some injectors I previously sold for an 06 5.7L charger and it was BLACK in color not blue as mentioned before)

FLOW RATES were taken from another website, but the numbers for the injectors are all the same and taken DIRECTLY FROM BOSH. Also please ask yourself why would MBZ/BOSH redesign injectors on the last model year? This would cost this millions of dollars in waste.

Good write-up,

but in 11/2005 MB for sure replace the old (black) injectors #: "0280 156 072", which is 397cc= 38lbs, to the new (dark blue) injectors #: "0280 156 304", which is 543cc= 51.7lbs..!!





ZAYED,,

My BOSH source says 0280156304 = 0280156072, please provide sources! Also someone with an 06 QUICK, go look at your injectors! You can remove the front cover with the MB Star and look at the passenger side injector in the front (its the easiest to see).

cm60k

MB continues M113K Engine only on SL R230 & W463 G55, maybe that's one of reason MB put 034 injectors to the final model of E55,


*important ques;, if any one go to dealer & order a set of injectors, which # they will provide 072 or 034..??


there are around 146cc differ between 072 & 034, means 06 should to have differ ECU tuning than 03-05, anyone with 06 can help with more info...

ZAYED,,

Thanks for your response, hopefully we get this all figured out soon!



All injectors above are interchangeable.

In that token your fuel pumps are old, need replacement, your electronics are old, replace all of them, your water pumps are old, your throttle body is old, your crank is old, spinning like crazy for 180k miles, your pistons are old they have been taking explosions for over 180k miles......
My sentence is old, it ran on and on

This is from another parts warehouse, they show this as a photo for the 03 injectors. I'm guessing black ones were 'oem stock' only, and then once the aftermarket segment for the AMG started making parts they colored them 'blue'??? Still doesn't explain why the flow rate is larger for the blue ones if they are both 'oem replacement' parts.

cm60k

Yeah sure, the good spare parts sources should know that MB replace the injectors from 072 to 304,

i asked dealer today they said 072 is NO LONGER AVAILABLE, if anyone need M113K injectors, they will gives 304 only,,

when i ask a supervisor why MB increase injector flow rate in 06..!?!

he said; i'm sorry im too late, i have to go to bring my son from pre-school..

The '06 injectors are different and are slightly higher flow...they are the same as the SLR...I posted pictures and part number and Bosch reference info in another thread...

It looks like best practices and realistic and rational preventative maintenance bothers you.

At 180k - yes - much should be replaced. Engines have wear items like bearings, rings, seals - if you wish for your car not to be a throw-away, then required maintenance is.... required.

Water pumps are wear items. Fuel pumps are wear items. Throttle bodies have seals and bearings - wear items. Pistons have rings on them - they wear. Pistons themselves are a wear item in the end.

yes - the engine from a dealer for this car is over 20k probably. But you can do a rebuild on one with all seals, rings, and bearings for probably less than 5k.

Only some 2006 models got the better injectors. My CLS had them as well as did a pull out 2006 E55 engine I bought to use for a build, but neither of the 06 E55s I had got them. Go figure. As cij911 said, they're easy to spot being light blue in color.

kponti

Best practices, and realistic RATIONAL preventative maintenance, absolutely agreed! Injectors being part of said category, I question.

Of course all those things could be replaced, its called an overhaul and not too long ago was almost required if you wanted to keep your car past 150k miles. My post was to say why stop at injectors if firing for 180k miles is why they should be replaced? Replace all those and then some or better yet, just get a newer lower mileage version.

True, any updates on this?

biggking

Waiting for someone with an 06 E55/CLS55 or SLR to get the numbers/pics of their injectors. At this point unless something new comes up, 03-06 injectors are the same imo. There's an injector testing/cleaning company about 30 min away from my house, if anyone's got those 'blue' injectors we can bench test the flow rate vs the 'black' ones and put this to rest.

Thanks for the reply. I may take you up on this. What do I have to do? sent you the injector? I'm about to pull the supercharger in a little bit, to start my winter project.
