Hello guys, I please need your help...

I had to dump my 2001 donkey c class with 460k with no issue because suddenly only bad people use diesels in Italy, so issues with circulating into the city!
Now I got myself a new donkey, a 350 ML US, but it has some issues.
Just to be clear, I'm a car collector 7+ cars, the "donkey" is what I use as a necessity vehicle...

Here are the issues before it gets boring...
1. Fuel Gauge, after cutting the battery shows full (it is) and slowly gets to sign empty, but no warning light (it works).
2. No sign or sound from the central locking, from key, from inside...not even blinking.
3. Wipers, works, but not if I ask them to, I mean, they move a bit, then they stop, pull the key...again and they stop. Then stuck again.
4. Outside mirrors will fold but no sign if I try to set them.

I pretty sure you are fed up with usual questions, but still, I would appreciate any help on this.

Cheers, Sacha.

 

Hello and welcome! Please post a photo of your ML.

Are the batteries new? Your vehicle has three batteries:

- main engine starting battery
- auxiliary battery - Mercedes calls this the "additional" battery
- key fob battery

Strange things happen when all batteries are not properly working.

 

Thanks for your answer!
I will post a pic as soon as it gets decent, I promise!
Main, and key are perfect... the auxiliary strikes me...I have no clue!

 

OK, all batteries are set, the additional is new and 100% charged.
All the same.
Next hint?

Cheers, Sacha.
