Try trickle charging the battery over night

^ this. I don’t use my stop/start much as that involves being in Eco/C mode but I recently did and found my consumer battery was goosed. New battery and off it went (not that I’ll use it again, but the consumer runs a couple of other functions too)

Well I bought a CTEK MSX 5.0 for £67.95 delivered from these guys:

Brilliant service, excellent communicators and very knowledgeable.

Thanks for the reply. Even if it was the battery shurly I should still get the orange light on the dasboard. I just did a 2:30hr trip down the south of England and back up north again I was hoping that might of fixed the issue.

In think you need to get it on star or checked by diagnostics somewhere, are there any other symptoms, maybe the battery is on its way out.

 

[ncarey265]

No other symptoms atall it was working fine then got in it one day and stopped working.

Hi, the eco stop/start doesn't seem to be working, is this anything to worry about. Or is there a "fix" for this ? Car is W205 C class C220 Diesel Blutec.

Isn't that a good thing?

Have you had the battery tested?

Have you had the battery tested?

Is there a separate battery, if so does anyone know where it is ?

I have had mine fixed twice now, under my extended (Tier1) warranty. Looking at posts on the various MB owner's forums, it seems to be quite a common problem with the W205?

The first time (around April/May) the dealership diagnosed the stop/start "battery" had failed its test and wanted to charge me for fixing it "sorry sir but batteries are not included in the warranty". I challenged this, as I had read that the "battery" is in fact some sort of flux-capacitor contraption, so I argued that it was an electronic component? In fact, on checking the warranty book, batteries are covered anyway!!

Fast forward to last month and I got a "auxiliary battery malfunction" message on the display, (everything worked fine, even the stop/start) which was fixed under the warranty. I asked if it was the same thing that was changed in May but was told it was something different! As it's a warranty job, you don't get an invoice so I am waiting until I go in for the next service in December, when I will request copies of the electronic service records (you can't just ring up for these but have to punt up with the V5?).

this has come up before... the small battery needs replacing, then it magically works they last about 5 years and can be bought and fitted yourself for 60 quid or 400 at a merc dealer including the diagnostics

as others elude to stop start is a terrible idea and "just wears out the engine...."

the benefit is not for the end user, but in merc selling more cars and allegedly showing they care about the planet... if you read the start of this sentence again, clearly they don't

About time for another update:

Service/MOT completed a couple of weeks ago and again asked about warranty work (V5C in hand). They said I could not have copies of the invoices as it was commercial information between themselves and the warranty company! I pressed that it was my car and I had a right to know what work had been done on it.

They reluctantly agreed to email me details of work carried out and yesterday, I got confirmation that in May, they replaced "the battery" (presumably the stop/start battery - that on a S205 is a flux-capacitor thingy) and in September, a voltage converter".

Needles to say I've renewed my warranty for the next year (thankfully, it was the same price too).

i am an old cynic, but i think stop start is a waste,time money ,effort ,and any ,slight fuel saving is going to get gobbled by the premature and costly replacement of starters/flywheel ring gears, if i end up with such a gimmick i will disable it tres rapidment. frankly if there is no other issue be happy.!

 

[phils]

What I have noticed, having had the flux capacitor bits replaced, is that even with the recent cold snap, the stop/start is still working fine (yippee - or not - depending on if you're a fan or not). ****** cold and still doing mainly local journeys, so maybe I was fobbed off by the "experts", who originally told me that it was normal for it to stop working in cold winter months!

Srop/Start - terrible idea! If I wanted to try and Sh#g my engine, I would take every opportunity to turn on all the electrics, headlights, air con, etc., then put the gearrbox in drive, before I tried to start it Repeat a few hundred times should do it.

stop start is great if you own a company producing cam chains....

wonder what produces the most pollution? fitting 2 cam chains + sprockets + tensioner, a starter motor, gearbox out for a flex plate, an exhaust system, an alternator and four or so batteries …..plus a replacement car (all within 9 years)...

or 5 to 10 gallons of petrol?
