Why do you persist in calling my mobile when I advise you repeatedly that I have poor signal reception at home and you should use the landline! And this is clearly flagged on the service worksheet! WHY?

Why, when you nevertheless persist in calling my mobile do you not leave the vital four digit extension when you know the MB phone-bot (on 020-7349 1420) requires it and provides no alternative! WHY?

Battery replacement fiasco – breach of warranty


MB Chelsea’s service department advised in June 2020 that both the main starter battery and the ECO stop-start battery on my C250 (2012 Reg.) needed replacement: I had flagged up a problem with the ECO “stop-start” functioning intermittently; I had not reported a problem with the main starter battery. However, I had both batteries replaced.

At a subsequent B service, on 21 March 2022, I reported that the ECO stop-start system was again functioning intermittently (since mid-February). MB “investigated”, said no fault was found, put the battery on charge overnight, said all was fine, but I should keep a careful note of dates and times should it fail again (to assist diagnostics), which of course I did.

The ECO stop-start system worked fine until it failed again on the morning of 15 April; it then functioned OK until the afternoon of 19 April when it failed again (after being driven for 10 minutes or so) and has not functioned since. This was reported to MB Chelsea and the car booked in for further investigation (under the battery warranty). This time I was advised that the battery may well be performing poorly but the warranty had been invalidated by me because the car had not been driven sufficient miles (approx 3,400); that in effect I had invalidated the two-year warranty by not using the car enough during the Covid pandemic lockdowns! Yet the main starter battery has functioned properly throughout and is unaffected by the light use! MB Chelsea again offered to put the battery on charge overnight for collection the following day (not knowing or forgetting they performed this trick in March). And of course this could have been done over the previous night when it was resting in your workshop because MB did not return my calls?

So what tests have been carried out to determine the battery is failing for the reason proffered and does not have a fault? No answer yet given. Did MB check that sufficient charge is reaching the battery? Why is the main starter battery unaffected by the alleged light use during the pandemic? No answers yet given.

Is this fast and slippery practice by MB Chelsea? - Just what one might expect from a backstreet dealer? – It’s certainly not worthy of the Mercedes-Benz brand – and quite possibly unlawful. A warranty is a warranty; I was not advised in June 2020 or March 2022 that a minimum regular mileage was stipulated to keep the warranty valid. Show me the warranty conditions attaching to the stop-start battery when it was fitted?

Why would I buy the Mercedes EQ that I have my eye on for later this year? Why would I reward such behaviour by MB Chelsea when the choice of EVs is so extensive?

Hello and welcome,

You're taking a 10 year old Mercedes to probably the most expensive main dealer in the country... :rolleyes:

Do you have a question, or are you just copying us in on your letter to the dealer?

Hello, welcome and vent...................


Breathe one two three, exhale......................

Imagine what it must be like to be on the receiving end of the verbal version, must be like being in Eastenders.

Reads like a rant at MB Chelsea to me.
I can't understand how the OP has invalidated his warranty by not driving many miles??
First I've heard of that being a condition.

Agree with Blobby above, why use MB Chelsea for a 10 year old car? The labour rates will be astronomical in comparison to a London Mercedes specialist like Wayne Gates. Considering the cost of an aux battery from Tayna is around £50, I'd be buying my own and forgetting any warranties with the main dealer.
And the eco stop start system not working is a bonus as far as I'm concerned. It's the first thing I turn off when the car has started.

Welcome Reardon

Good luck with the EQ; you might seek some advice here before making a final decision.

I don't live in London, but am sure that there are a number of excellent indies including Wayne Gates:-

Welcome!

The point MB Chelsea are making is a valid one if you don’t run the car enough the main battery will lose more voltage than the alternator can replace while the engine is running the remedy to this is to use a top-up charger (CTEK or similar) say every three months to maintain battery function which the ECO Stop/Start system is heavily reliant on.

To the OP get the waranty information for the part (battery) from the dealer.
Have a read and see where you stand. AFAIK parts are 2 years unlimited mileage. To have a clause (must be driven xyz miles) is utter horse p00.

Welcome to the forum.

There are several dependency interlocks for the start stop system, temperature, current draw etc as well as the state of the battery so are you certain the battery is the fault here ? A simple check would be to use a multimeter to compare the voltage of the battery just after the car has been run and then again after 1 or 2 days of the car not having been run. Fortunately the batteries are not too expensive. A vendor such as Tayna Batteries should be able to deliver within 24 to 48 hours and it wont be difficult to changeover. Youtube videos will guide.

I suppose you could try calling him on his landline and asking him (his mobile gets poor reception) but don't keep the phone near to your ear.:)






Why do you persist in calling my mobile when I advise you repeatedly that I have poor signal reception at home and you should use the landline! And this is clearly flagged on the service worksheet! WHY?

Why, when you nevertheless persist in calling my mobile do you not leave the vital four digit extension when you know the MB phone-bot (on 020-7349 1420) requires it and provides no alternative!
WHY?

He needs to remove his mobile from MB and ensure only his landline is on file.
Why folk whine about somethings that are in their control is beyond me. WHY

Wouldn't occur to me to take a 10 year old car back to the main dealer, (unless I needed thier diagnostic equipment) 10 years old is end of life motoring now, 90% of cars that age (including Mercedes)are dogshit anyway.

Has all the appearance of someone wanting their complaint to come up at the top of a Google search, as many posts on MB forums do for MB Chelsea etc.

Would say this is definitely just a rant for the sake of it, or to get to the top of the Google search as the OP hasn't even been back on the site since posting.
