Blue Efficiency injector recall?

[Mark-E]

I wrote to the CEO and asked if the vehicle was fit for purpose, if not could they please keep it and arrange for a full refund.
They kept it for 3 weeks and let me have an identical replacement during this period. They then wrote to me and confirmed it was now properly fixed and indeed fit for purpose.

No idea why it took so long to repair, I was in no rush, but I have retained that letter !

Common Rail Diesel, Killed one thing, the reliability of Diesel Engines.

Direct Injection, Pre-PD, the old Bosch Distributor Pumps. Were indestructable in VAG Cars for Example, the Old 525TDS a Great Motor, the E300 TurboDiesel and C250TD all great machines, which could go and go, without incident of injector problems etc.

A recent drive of a 2.0JTD Gulietta saw me return only 39.8mpg on a motorway Journey. So I'm afraid all this about power and economy is unfounded, Particulate filters are service parts, they either get force generated burning them off and releasing what was supposed to be captured back into the atmosphere and being sent to landfill.

Give me an old unrefined old burner with a huge turbo on any day.

Typical Fiat/Alfa invented Common Rail Technology, what were Bosch thinking to buy from almost bankrupt italians, and speaking from experience I had the high pressure pump go on a Primera, although a renault engine... and multiple injector failures on a Mondeo TDCi, yet over 200k later my Octavia 1.9TDI is still running original clutch and all, purring away nicely sold to a mate of mine.

I also found the MPG of the Primera shocking 2.2DCI returned around 30 around town.
Mondeo was good 43 and 50 on a run.

Octavia I couldn't get below 50 no matter what I did. The Pre-PD Bosch VE 1.9TDi is a superb recommendation to anyone especially the 110 chipped!

That's why I've turned to LPG! and never ever had a problem!

Someone I know who was the Design Director for a major diesel injection system manufacturer told me a few years ago that, in his opinion, Common Rail was flawed technology. His view was that the Pumpe-Duse, or unit injector, technology used by VAG was far superior. The trouble is that PD injection systems are considerably more expensive than Common Rail, which neatly answers why VAG engines don't use PD injection systems anymore.

My previous post dated 11/6/11 refers. The car is still with Mercedes and they are of the view that the injector wiring loom and sensors are defective. Unfortunately there is an indefinite backorder for this part, Im not sure if this is due to a waiting list but I have been told that the part is awaiting manufacturing in Germany!! Has anyone heard of this problem?

Just received a letter from MB saying that as part of their performance monitoring they are carrying out secondary checks to a 'select vehicle set'. My car has been chosen to be in this set and I will be booking it in next week.

However, just wanted to see how many of you have also received this letter. Is it being sent to all those who had faulty injectors? Do MB know something they are not telling anyone?

You can bet Your Nether regions..."Do MB know something they are not telling anyone?"

What MB "Knows" is that it Does Not Know REALLY know what the Problem Is!

Common Rail will turn out to be the biggest affront to Compression Ignition
Technology in the last 100 years.

You just can't "DO" Compression Ignition (Or Turbine Technology) "On The CHEAP" !

Agreed.
Also it's worth noting that the greater refinement and power we want is created by adding injector pulses. The more pulses, the quicker they wear out.

Yep I've just got one of these letters - came from the dealer though rather than MB itself. When I called to book it in they suggested it was a software check of some sort that will take around an hour to do. My car has now done over 20K miles since its injector change without incident.

 

[CDL]

Car went in for its 'quality check' and I was told it was something to do with a recall from 8 months ago. If my memory is correct, this would have been the power steering recall, rather than anything to do with fuel injectors!

On another issue, MB could not find any faults to explain why the car suddenly starts to stutter (shake) when driving, as if engine is not getting enough fuel. Hope this is not an early sign of injector failure!

 

[spartacus45]

For those whose vehicles have suffered from injector issues (w204), the original injector wiring loom has now been superseded with a newly designed one, I had one fitted recently. So far it appears to have resolved instances of power loss/stuttering that were occurring from time to time.

 

[Hammy]

My car went in for its "select vehicle set" inspection last Saturday. Receptionist said it was related to a previous recall. No problems found apparently, although I am wondering if that revised wiring loom has been fitted.

 

[Lostprophet]

Problem sorted or do I get a jag/BMW or Audi?

Has mercedes sorted out the issue with the injectors?

 

[hawk20]

Has mercedes sorted out the issue with the injectors?

Yes. Long ago.

See J.D.Power survey 2011 where E class just been chosen as top large executive car (1st equal with 5 series).

thats a strong indication,as my e250 did the same and then shutdown
get it checked out now

2011 US E350 Bluetech

I have my 2011 US E350 Bluetech for 3 months now. Never heard of an injector problem. This is not surprising since there are very few Diesel's in this country.
The local dealers know little about this cars.
This is obviously something to watch out for.
As far as initial quality is concerned this is the best car I owned.
Hope it stays this way.

Off topic: Is there any technical documentation for this model-year available in the UK?

Thanks, Jurgen

 

[grober]

Perhaps they are monitoring all cars that had their injectors changed previously to get an indication of how successful the new design of injectors/wiring loom/ software upgrades are holding up in the real world. So this could be good customer follow up or alternatively you may be part of a large scale "involuntary " quality control experiment.

MB 'checked it out' last time I took the car in. They had no idea what the issue was and told me to 'keep driving and see what happens'!

A bit like my fuel economy, which was rubbish, but as they could find nothing wrong, it was delcared normal! Funny how it massivley improved when the clucth had to be replaced!

 

[jac]

Well my W204 sport C220 CDI Blue Efficiency has just had it's second lot of injectors fitted along with a new wiring loom, it's a 59 reg with 20.000 miles on the clock.
I just had a B service a week before they failed.
I wonder who will pick up the bill if they should fail again shortly after the Manufacturers Guarantee ends, thats if i still have it by then.
Just out of curiosity anybody know how much that would have cost if i had to pay the bill.
Having said that i really like the car, good mpg, comfortable and looks really nice in white, well i think so.

 

[compress ignite]

Grober's "called" it.

ALL owners of this engine series are VICTIMS of Involuntary Q. C. for
Mercedes (And Delphi the subcontractor)

Lostprophet,

Mercedes can't have sorted out the problem...They still don't know what went wrong!

Heresy! But, that little 3 Series BMW Turbo Diesel is a Screamer. And the soon to be seen 5 series TD looks interesting.

Parker15
(Jurgen),

I may be mistaken,But I thought only the 4 Cyl. Diesels got the BAD Injectors.
One sure way to tell...LOOK at your Injectors...Are they made by Delphi ?
[Then you're in the same boat with everybody else on the Continent,Driving a Mercedes
Test Bed "Time Bomb".]

Mercedes has No One But themselves to Blame...Allowing Delphi to Attempt a "New to Them "
Technology...to save a few Beans.
Had Mercedes used BOSCH as the Primary supplier as they've done since time Immemorial
None of this unnecessary foolishness would've gone on.

To put the icing on the cake the ****er who was in charge of all the customer service
Manipulation (servicing the Newly disabled vehicles and forcing customers who'd already
been waiting MONTHS to wait even longer.) @ Mercedes UK has been "Promoted" and moved to the U.S.

JAC,

After all this,if they asked you to pay for Injector service 9 years from now...I'd have it
Flatbedded to Stuttgart and set fire to it on Mercedes Front Lawn.

Injectors again

One injector in my GLK went south. This time they are changing all injectors. This is third set in my car (60000km). First set was changed in two phases, two incidents and second set was changed as a precaution.

Plus side: In two hours, they had my car in dealer and I had red C180CGI as a temporary replacement.

I'll keep you updated with this.
