Mercs will go mental if volts below 12.1V

these things need their own extension lead to the mains... but then USA only get 110v, so maybe need two extension leads

So the car is now at the Mercedes Place they plug the computer into it and it couldn't talk to the car computer. Funny thing is is I have to wait 3 weeks to bring my car there so we hired a tow truck and move the car there we told them the wheels were locked that the car was almost impossible to move and they were like yeah we have this hub thing. Then the ******* calls today and says we still don't know what it was it was outside it was raining and we just didn't want to get wet, really? So they told us that they're going to have to hire a different tow truck to come down to move the car to a bay and that they would just pass on that price to us. I'm like hold the **** up. We paid for a tow truck to bring the car there at the fifth tow actually, I don't care how you get it in that bay but I'm not paying for it..

Anyway I'm a side note I came across this on YouTube does anyone know where this is and the S550 w221?

it should say "don't turn off, leave in Drive, and immediately get it on a ramp at a workshop to swap out the ISM (intelligent servo module) - or you may become stranded"

yours sounds really great - you'll have to get in neutral or P to get it to crank.... and in doing so might end up stuck (but ur already stuck), if it doesn't play ball its pick up the car on low loader and if stuck in P, get it out, or disconnect prop shaft (you must never tow an auto without taking prop off !!! )


.
So I finally got my car looked at and they like you said it was the computer $2000 later I am supposed to.pick up the car from the mercedes mechanic here in my small town. He now says the front battery is bad. Could that have been my problem from the start?

no -

certain bits die all day long on the W221 - we should all remember they are built as toys, for corporate crooks who fund them by stealing the workers wages, all merc did was decide they wanted to play in that arena and steal some of the cash being flung around... so they build most of it to die early and get rich from the spares / service department..

the mugs are those further down the food chain who didn't realise in the last 20 years that's the way the world works... but it is a shame the irresponsible lunacy has killed the planet…

Hey I just experienced this problem today out of nowhere and I’m hoping it’s a voltage problem as I have been told my alternator needs replacing and I occasionally get the red battery icon on dash while driving. What battery should I try replacing ? Trunk or engine bay? Thanks..
