Just filled up the Car with VERY Frothy Diesel, started off for home when the Engine Management Light Illuminated, book says Yellow, I say Amber!:rolleyes:

Fault Diagnosis mentions Fuel Problems and it MAY go Out after 4 or More Full Stop and Ignition Off Sequences, anyone have a better suggestions?:dk:

If not I will have to think of Booking it in with the Dealer!:doh:
 
Not 100% sure, but I think the fault code will need to be reset before the light will go out,

Hope you have a better experience than mine. My 1200 mile C43 has been in the Dealer's for nearly 3 weeks with this issue. Part of the solution was that they had to update the software, during this process the laptop crashed and so corrupted the software on my car. The dealer then needed to wait for a software patch from Germany to get my car working again. Patch arrived and was installed. dealer thought car was good to go, they tested it and it was working fine. I go to collect car, they drive it out of the workshop and the amber light comes back on. So the car is still at dealer. The current thinking is that it is an electrical problem rather than a mechanical one and the car may need a new digital cockpit.

So good luck with yours! The advice per the manual is correct, if the fault does not correct itself, book it in.
 
Spoke to Mercedes Peterborough, they suggested that I do not drive it and call RAC, RAC are going to take it to Mercedes Cambridge, just around the corner from where I work, then wait and see if Star either Clears the Problem or shows up more information! :eek:

Decided it's going to be a Looooooooooooooooong Day!:doh:

It's Official, I can now tell myself "I told you so"

RAC turned up at around 10:30 on Friday, took me 2 miles round the corner to Mercedes ?????????, took the Car off the Low loader and asked me to Drive it into the Servicing Parking Area! CF No 1 (Cluster F*#k)

If I had to Drive to the Garage it would have taken me 2 Minutes as the Crow Flies, I can see into their Offices from where I work, CF No2.

Get into Reception: Who are you? No one is or was expecting you and you guessed it, the Truck has long gone. CF No3.

Have a Coffee, sit and wait, do the Crossword and wait some more, eventually Service Desk realize I exist, Explain the Problem, “you are in a long queue with 8 Staff of sick” OK where’s my Hire Car, “ERRR, no one has Ordered it Sir” CF No4.

Sit and wait, decide that I am going off Vending Machine Coffee!

14:30 Call on my Mobile, “Are you waiting to a hire Car from Eurocar Sir” Answer: “I don’t know but I will take it anyway” “Were just washing it for you now Sir” CF No5

15:45,” What’s happening to my Car? “It’s still in the queue Sir, and there are other folk coming in with Problems”!

At least 4 folk have come in telling the Service Desk that an Unknown Light has appeared on there Dash, 3 of them were Low Pressure in their Tyres, a Mechanic is called and basically Blows their Tyres up for them, the SAME Mechanics that could have been available to Connect my Car into Star! CF No6.

16:00 a CLA 200 is delivered with apologies for the long wait, I try the Servicing Desk again, I’m travelling to Peterborough, so I don’t want you calling me back telling me the Car is Fixed BIG MISTAKE! MY CF No1.

Saturday Morning, can’t settle, can’t do anything as I’m waiting for the “Car is Ready Phone Call, gave up after 12:00 and had a few “Alcoholic Beverages”

Back at work 05:30 Monday Morning, hankering after going round there to see if my Car had moved, managed to NOT go there!

12:30 gave up and went round, car is still where I left it, count to 49 Million before approaching Reception.

Get into the building, Receptionist remembers me from Friday, Ask the Question, “Update on any Progress Please” “Ahh, it was Rob, that was dealing with your Car, I will tell him you are here”

Rob disappears through the Door at the far end of the Office! CF No7!

Eventually some young Lad was selected, “Short Straw I’m thinking” “We haven’t had a chance to look at your Car yet, but it’s next in line to be moved into the Workshop” His young shiny Nose Extended an inch for every word he spoke!

“I live in Peterborough, I leave work at 15:00, the Car Hire runs out on Wednesday Afternoon, I’m supposed to be travelling up the Edinburgh on Wednesday Morning”, (My input to the Pinocchio Nose Lengthening Derby)!

“Well give you a call later this afternoon Sir” CF No8!

Meanwhile folk are coming is with all sorts of Spurious Lights on their Dashboards, at least one was “Low Level Fuel”

Tuesday 14:30 called the Service Desk, “Thank You for Calling Mercedes ????????? Your Call will be Recorded, Press 1 for Servicing, Press 2 if your are requesting a Servicing to take place, Press 3 of your are asking for an Update on Servicing taking place!”

Pressed 3, “Thank You for Calling Mercedes ????????? Your Call will be Recorded, Press 1 for Servicing, Press 2 if your are requesting a Servicing to take place, Press 3 of your are asking for an Update on Servicing taking place!” Gave up recording the CF Numbers!

Pressed 3, Rob Answers, “Ahh I was just going to call you (Pinocchio Again), I was going to see the Mechanic and get an Update, I will Call you back in 5 minutes!”

10 Minutes Pass and Phone Rings, “It’s the Pump” “What Pump” “I don’t know, but it’s on Order” “When will it be in” “Maybe Tomorrow” “ Well will it be Tomorrow, or not ?” “Yes it should be” I reiterate my intent in getting to Edinburgh the next day (Wednesday IE Tomorrow) and the Hire Car must be returned by 15:00! “Ahh, just a second, OK It will be in tomorrow, when you need to leave work?” “Early as possible”

09:30 Wednesday Morning, I deliver the Hire Car to Mercedes ?????????, Rob takes the Keys, apparently the work will be done by Midday!

This is where Mercedes Me, came in handy, I knew when the Ignition was activated (Message) and when the Car Doors and Boot were Locked and the fact that the Car had Travelled 5 Miles (Road Test).

Phone Call at 13:30 (Wed) Car is ready, walked round there to pick it up! :banana:

Fault was nothing to do with Frothy Fuel, the AdBlue Pump had Failed, the AdBlue Sensor, was Indicating the Fact that the AdBlue Level was 80% so the Car ran as Usual (Sounds Odd to me) but as the Pump was not Running the Engine Management Light was Illuminated as it was assuming that there was no AdBlue Available?? :dk:

Car runs fine, my only worry and I mentioned this to Mercedes ????????? was the fact that the AdBlue Pump Failed at around 17,150 Miles, he intimated that it was NOT a known or Regularly Listed Fault! :rolleyes:

Note: The Pump comes as an Integral Part of the AdBlue Tank! :wallbash:

PS: Can I claim Megga Smartie Points for the Longest Posting Ever?:D
 
Jesus that sounds like a nightmare!! We've done quite a few AD Blue pumps so its not uncommon!
 
Just wondering, if you were living in Stuttgart, would you have received the same poor service from the local Mobilo and Dealer... or is this a UK thing?
 
Wow you were far calmer than I would have been,the dealership would have been in lock down with me shouting you will never take me alive :D
 
t was a bit of a Nightmare!:wallbash:

I'm glad you got there, sorting the car that is.

Todays cars are near unrecognisable from my early experiences with them.
In the 80's the utterance of,
"that'll be your ABS speed sensor mate,"
"sounds like your DPF is blocked,"
"it might have run out of AdBlue,"
would've got the response of "what planet you from?"
"File yer points a bit it'll get it going", was more like it.

And this Mercedes ME jiggery pokery would have had you whisked off to Area 51.

Back in the day the issue were usually moisture inside the dizzy cap or burnt points......

Have you any Numbers to back up your "Not uncommon"? Mileage, Age, Model etc!

We've done 6 since March - so I wouldn't say uncommon!

6 year old E-class, 41k
6 year old ML 60k
3 year old S-class 80k - just out of warranty!
4 year old C-class 42k
4 year old c-class 35k
5 year old S-class, this one had done 148k though!
