OM656 Failed Vacuum/Oil Pump and loss of braking.

[Dchamdal1]

he good aspect of this claim however is that Mercedes have issued a full recall on all

So I am in the south of Ireland and the car was out of warranty
local Mercedes dealer submitted the warranty claim to Mercedes Ireland and it was actually rejected on a Friday morning
So he contacted Mercedes Germany who told him to re-submit the claim the following Monday
We sweated over it but thankfully it was accepted and 100% covered.
It is a HUGE job, the whole engine must come out and the actual work took about 5 days, we were without the car for maybe 4 weeks between diagnosing, submitting the claim, waiting on parts and the actual work carried out.
I'm told it is a new designed pump they are putting in so should not happen again.

I've been sweating all day ever since I found out just like you probably was but your response has calmed my nerves somewhat so thank you and I'm glad it all worked out for you. Out of interest did mercedes provide you with a courtesy car during the 4 weeks? I'm left in limbo at the moment and need to arrange alternative transport if Mercedes are unable to provide me with a courtesy.

I gather from the forums that circa 12k is the back park for this type of repair, but I wonder to myself why? What is it that racks up the bill so high? Surely that sort of price is new engine territory?

Eng out cos designers are idiots and the consumer never thinks about it at purchase.. Engines in backwards = engine out for small jobs that create big labour costs its high time makers employed guys that have to repair stuff in the design team i
Bumpers off to change light bulbs, engines out to change vac pumps ect all modern bull xxxt to keep dealers busy n shave 2 min of production time.

Courtesy car provided for just one week when the actual work was taking place.
We didn't purchase the car from the local dealer and had only been there for one service a couple of months before the failure so I presume if we were regular customers there would have been a better chance of a car for the duration.
We managed away as we have a second car though you get used to having 2

Mercedes have called today to say my car has been repaired. So lets see what it's like when it is returned!

Hi moj91, how has it been performing since the repair? My GLE 400d 2022 has gone into limp mode a few times recently and is due to go back to MBUK for investigation this Friday. Thanks

Engine seems fine, but definitely down on power since the repair, im wondering if they changed the ECU map/software when it was in.
I have had issues with the power trunk/boot jamming open, and odd rattles/clatters.
Since the car went in for the above, i have had numerous issues with the starter/main battery discharging or not holding enough capacity. MB say they bench charged it, this resolved it for maybe a month but since then i have had to jump the car several times - the car is rarely used for short journeys, often 4-5hr drives in a single stint, and i keep the stop-start turned off, so i think the battery is shot from the car standing at the dealer for 3 months, but they won't agree to replace it. I will kick off about it soon when i have time.

As often pointed out mb (n prob other motors now) don't much like batts that don't hold tip top charge.

Thought I should add my experience. My car is an E220d estate purchased new Dec 2019. The only symptom was loss of braking power. When I took it in the service manager clearly knew straight away what was causing it. He later told me that this one dealership has had 5 cars in with the problem in July alone. They seem to have set up a mini production line in the workshop, because the machinery needed to lift the engine and gearbox can only handle one vehicle at a time. So basically you just join the queue. After 10 days I got a loan car, a 220 cabriolet, which isn't much use but at least I'm mobile again. No estimate has been given about when the job might be completed.

HI guys, I've just joined this forum today, after researching the issues going on with my GLE 400d, and the double pump failure. I'm sorry some of you here have to go through this crap situation that I'm going through now. My car has 50,000kms, and just got out of warranty 7 months ago before thi happened to me. We tried to speak to Mercedes and they said they won't cover it, as MB hasn't issued an official recall on these parts, and I'm staring down a 12 k Eur Bill. I'm done with Merc, I tried to extend my warranty but here in Cyprus they don't offer that as an option. Unlike Porsche I can purchase an extension for up to 7 years. I guess they know their designs are flawed. I'm definitely selling this car once the repairs are done and likely never buying a merc again. It's a shame, the car is beautiful and packed with goodies, but if they can't get the most important things right, what's the point.

Is is possible to complain direct to your local corporate office? State that there are recalls elsewhere in the world and you are considering legal action to recover your outlay? MB customer service really has gone down the toilet recently...

Is there any one here who can send me a link to any official recall of the part? That would definitely help my case if I were to complain. Cause the dealer here clearly stated to me, that no official recall from mercedes means they can do anything.

My 2018 E200d is with the dealer waiting on the tandem pump replacement. Luckily Mercedes are covering 100% of the cost as goodwill. We have full Mercedes service history, 140,000km.
Its a great car but this has shook my confidence in car so will most likely move it along later this year.
Has the replacement pump been redesigned so we won't face this failure again?

I suppose anyone reading this thread already owns a Mercedes but if you don’t then please stay away from them.
Now I have the adblue sensor problem and near €2000 to fix
Such an expensive piece of German junk sorry I didn’t get rid of it

It’s not just a Mercedes issue… it’s an emissions reduction system issue that drivers aren’t made aware of until it is too late.

There shud be a health warning on all adblu egr cars on showroom details

 

[moj91]

My E400, as the OP, is coming up to its warranty expiry, i am looking into taking out the MB extended warranty - but i need to establish if it is worth the paper it is written on. If not, the car needs to go because my faith in it to not throw any OTT huge bills over the next 5 years is shot.

If the warranty is with MB then it’s good, anyone else - not worth that paper it’s written on

I need to sit and read what they include/specifically exclude before shelling out, although i did cost for the extended warranty in buying the car. Feels like last month i got it - its been nearly 2 years!

 

[moj91]

The MB warranty excludes, which i would have expected/liked:

All 'trim' - including interior. So if the glovebox falls off i'm stuffed.
Lamp Units inc. any/all LEDs - so that's the multibeam LED headlights not covered. Not good enough.
Release cables - i'd expect them to be covered at lower vehicle ages.
Brake pipes and hoses, same as above,
Failure caused by a failed seal/gasket/or sealant. Also not good enough. They could attribute that to many things.
Plus the price has jumped from £490 when i looked last year to £774.... clearly they know how unreliable their vehicles have become!!!

Not filling me with much confidence!! ...what to do....

Did you ever resolve the perceived power loss since the repair?

 

[sonic]

I have owned cars for the last 55 years, & two cars in the family for the last 41years. In all that time I have only had one problem car, an Austin 1300 which I bought tax free in Germany in 1972. I have only owned two new cars.
The idler gear failed at 17K miles outside the 6 months tax free warranty. The clutch failed at about 18 months, the only clutch I have ever had replaced. The battery just after that, & the wiper motor. I am sure there were other issues which I have forgotten.
At 2 years & 3 months I sold it, & got a surprisingly good part exchange deal on it. In fact I lost almost nothing on it as the tax free price was about 50% off the UK price. So my advice is get rid if you dont have confidence in your current car.

No - i just lived with it. I suspect the car had some software changed and this reduced power output.
