Blue Efficiency injector recall?

[alo]

Got my car back yesterday

All four injectors were replaced and also the wiring loom.

They couldn't say if new injectros are any better that old ones.

I guess I am going to send a new letter to Daimler AG, this time registered...

Injector Part numbers

Hi, I'm new to this forum.

Am just in the process of purchasing a 2009 C250 CDI sport, registered in November.

I have asked the dealer about the injector issue and the need to change them. At first they played dumb, 'what injector issue?'. I pressed a little harder, saying that they surely should be aware. 'Oh yes, they have been done' I am told.

I've asked for this in writing and also for them to confirm the part numbers of the injectors on the car.

My question is, which are the part numbers to look out for? does anybody know the P/Ns for the faulty injectors?

And equally, what are the good part numbers?

Many thanks for your help,

John

isn't it disappointing that these injector issues were not discovered during the hundreds of thousands of miles of testing? the most comprehensive development program ever?

Hi.
Agree. Pity that Mercedes Benz continue to use their customers as Beta testers.

My 2000 E320CDI was replaced by MB in 2001 as a consequence of continual warning lights. MB eventually wanted to fit a German Spec ECU onto the car for me to "try it and see how you get on". I was to become the only owner in the UK with a German Spec ECU!

When the car was eventually changed by MB I asked about its fate. "Sold it a day later" was the response. So the dealer moved my lemon onto another customer!

Eventually, some years later MB accepted that they had never actually tried the ECU and software together under road testing conditions but had done done so separately prior to manufacture. The result was a significant number of 2000/2001 pre facelift with major problems as a result of the inadequately tested software.

Appears some things never change. Customers Beta testing again.

Vectra

If you take the plastic cover off the top of the Engine you can see the four Injectors. These have dates of manufacture printed on top. If the Injectors all have 2010 dates or later you should be fine.

I had injector wiring loom replaced, a couple of months ago, some months after injectors and notice a different, for worse at:

- engine sound (more metallic)
- engage between clutch (manual gear box) and engine
- 1st gear, RPM's fast upping and car almost not moving
- increase diesel consumption

Anyone confirm any symptoms?

I'm not much confident with my Dealer.

I've learnt that there is currently a "service improvement" for these engines. Not a recall, but something they will do when the car is returned for normal service. The issue is around the rubber seals that sit between the injectors and the wiring. The injectors can leak diesel up into the seal and cause it to swell. This swelling is seperating the electrical contact causing intermittant missing. The "service improvement/enhancement" is to replace the wiring loom and fit newly designed clips that hold the wiring in place on the injectors to counter the effect of the swelling seals. In a few extreme cases the diesel is leaking past the old seals, inside the wiring and back up into the ECU.

Well i thought this had all gone away,

I have a 2009 E220 Cdi Sport. I suffered, the original Injector Failure, in December 2009, a second Injector Failure in 2010, and on Saturday just gone, I suffered a third Injector Failure.

I honestly thought this had been sorted, but reading through the recent posts, obviously not.

Should of guessed when the fuel consumption changed from an average of 42mpg down to 37.1 mpg

This is now the worst car i have ever had the mispleasure of owning. Lots of niggly little problems,

Bluetooth keeps disconnecting
Radio doesnt re-tune to a stronger station
Electric Window dont go up on one touch ( they used to )

Luckily i only have to suffer with it for one more year, no doubt it will be another interesting experience.

 

[Empi5]

Forgot to add my mileage is 46000

Just had a call from the Dealer, vehicle is fixed and is now making its way up the M1 on the back of a flatbed ( where it feels at home )

Unfortunately i now have to return the E350 Cdi oh hire, which i liked very much !

Let us know how you get on if you have this service campaign done on yours.

I have a very strong relationship with my local MB dealership and I trust that the staff who have looked after me so admirably on every occasion, would not put up any argument against sorting out any issues I may experience with injectors on my new car.

My car recently had its first service and MB Lookers fixed a 'known' issue with the fuel filter, without question. This was over a week before I received a recall notice to have it sorted.

Just thought i'd add my tuppence of faith in my local MB dealership to this, even though I remain cautious about MB UK.

Now the FUN really begins...

Stuttgart is "Gifting" North American Mercedes with this motive force in the
2013 GLK series,available sometime in March/April 2013 in the USA.

2013 Mercedes-Benz GLK gets its diesel on - PeachParts Mercedes ShopForum

This will answer my long standing belief that Stuttgart "Kinda" uses GB as
Involuntary QC for other markets.

The "Gentleman" who was in charge of C.R. in GB for Mercedes has been
"Promoted" and moved to the USA.
('Should've seen THAT coming.He was successful at Hoodwinking 25,000
members of the E.U. who'd purchased that Engine into "Swallowing IT.")

Can't complain

Bought my '59 C220 mid-June this year. Was told about the injector recall about three weeks ago - was told parts were on order. One week later parts were available, one week later job was done.

Dealer said that they didn't know why the injectors were being replaced, (yeah right !!), but they did say that they were doing about 30 cars a week!! and that it was causing some problems for them fitting in routine work.

Must be quite a cost for MB in all of this - even if the original manufacturer is picking up the main cost.

W212 E250 CDI Sport November 2011

I've just been told that our late 2011 E250 CDI Sport is to go in for "Injector replacement & parts on the fuel system to be replaced upgraded including adding additional pipes".

Anyone any more information on this?

I thought my car was built long after the injector problem but sounds like more problems have been found.

I believe they are changing to Delphi solenoid injectors. Requires a new ECU and leak off pipework. I'd be interested to know the injector part numbers on your vehicle. Mine are piezo A6510702787. The solenoids are A6510702887 on the 250, A6510704987 on the 220.

I'm test driving a C250 Cdi BE Sport tomorrow at my local MB dealership. Does this model suffer from any known issues, apart from this injector fault?

I'm selling my C220 Cdi because it has a turbo lag which I consider to be dangerous. This has caused me to find myself in several situations (would have been where I wanted to be had the lag not happened) which I would not normally find myself in while driving.

Why is MB releasing cars onto the market with such issues? My biggest gripe is that i'm losing a few grand in changing cars because of a manufacturing fault. I'm wondering if there's any redress possible for this?

 

[paul73mt]

Have you thought of getting your car 'Mapped'??? this i belive would give you more torque, BHP and most remove a lot of the turbo lag

 

[pmcgsmurf]

A6510701287 on the injectors.

Not sure where the solenoids are?.

One car has been done so I'll have a look at that tomorrow and compare it to the one that is still to be done.

 

[pmcgsmurf]

One car has been done so I'll have a look at that tomorrow and compare it to the one that is still to be done.

The car that's been done has got injectors with what looks like a solenoid mounted directly on the injector.

Part number on top of it is A6510702887.

Not sure how to tell the injector part number, can't see anything on it.

Also looks like an new ECU has been fitted, part numbers on this are A6519005301 & A6519013301.

When does the lag appear if you find it dangerous? Is it when moving off from being stationary?

There is a hesitation issue on early blue efficiency engined cars but that only affects the cars when you're pulling off which can be quite dangerous on a roundabout etc. but majority of those issues were rectified by gearbox software updates

Thanks. A6510702887 is the solenoid type injector part number I was referring to.
