Hi, I hoping somebody can give me some idea why my '07 ML is having some kind of electronic breakdown ! Drove 2 min up the road warning light comes on to say the bonnet is open, then the third brake light had failed, then the red car outline, then it came up left side SRS failure. Parked up...

Yesterday I called out Mobilo because I had a flat battery on my W204. The engineer that came out jump started it and then was monitoring the voltage values via an engineering menu in the car, but it was being displayed in the centre circle of the speedo. Does anyone know how to access this...

Take a 12v battery which from new starts at around say 12.7V. When it reaches 11.9, it is supposedly discharged. How can a battery at this level still turn a car over fine without any trouble? Or is this not what is being referred to? (Measured on a multimeter)

Looks like I'll be parking my 15 plate E 220 bluetec for a couple of months while we're away, will the battery or batteries have enough left to start it up again after this length of time? How many batteries has it got anyway, I know there's one under the bonnet passenger side, but is there...

Our 2006 ML 320 CDi seems to be having something of a hissy fit at the moment. 1st symptom: was occasional car alarm problems, random alarms even with tow and interior sensors turned off. 2nd symptom: after a couple of weeks we found the tailgate would not open - and then it would Now...

So, my CLS has been sat still for some time covered up and as you'd imagine the battery is knackered. Tried charging it but not having any of it so I have an OEM one I'll be picking up today. Over the winter I know the car will be laid up and covered as I won't be using it during the winter...

Hi We bought a brand new GLE in April last year. Rarely open the windows via remote control but noted this summer the windows would not open via remote. However, the open/lock and open/shut boot worked well from close by and distance. As it got hotter I thought I'd try the new/spare key...

Hi all, The instrument cluster on my SL has been illuminating of late in the Red Alert mode, the left cluster shows the Battery icon whilst the other states "Visit Workshop". The issue being is that nothing seems to be amiss. Both the starter and the consumers batteries are performing as they...

Hi guys, Just had the auxillary battery malfunction light in my E63. Its a 2014 W212 on 21k. Anyone had this before? Is it just a case of replacing the aux battery in the boot? If so any recommendations of a good quality replacement that will stand the test of time? Thanks in advance Iddy

Hi, I've got an Auxillary Battery Warning message flashed up in my car this evening and the annoying thing is my car warranty expired last month. :mad: Anyone know how much it will cost to fix it by the dealer? I also understand there isn't a 2nd battery in the w205, so what can the problem...

Hi guys, my name's Bobby i own a Mercedes E300 Hybrid ESTATE . Few days ago i had the ''AUXILIARY BATTERY MALFUNCTION'' message on my dash and since then it's been painful times as i cannot find the location of said battery. Went to 2 garages, MB dealership, everyone is wild guessing, no one can...

I did have a search to see what I could find on here and it seems that this error, likely/possibly correlates to the battery in the front being knackered? So I got myself a replacement battery. The main one was changed last year and although I know that sometimes needs a charge due to...

Hi all, I'm in France at the moment, had a message displayed today saying that the auxiliary battery had malfunctioned. As far as I can see, the only problem seems to be that the eco stop/start isn't working. I've had a look on Google, and I don't think it's exactly an emergency, but can...

So I got this warning today, I'm guessing alternator but the car is running fine! Any ideas here? Thanks Steve
