Please read if you have electronic problems with your car.

So i didnt want to make a new thread about this but i decided i should because its going to save people alot of time and money. Big shoutout to "NASA" on here. As some of you know my mercedes was having some electrical problems and i decided to take it to mercedes benz because it was under warranty. they replaced 2 parts and said the problem is fixed picked car up and same night all of them were back. I sent the car back they said they will replace some more parts. I told them no and got my car towed back to my place, went to CT got a new agm battery and replaced the old one. CAR IS PERFECT NOW. been 3 days no problems whatsoever, So if you have electrical problems(alot of them) please just replace your battery first. Its a cheap step to steer away from a second mortgage. Again NASA was right hahah.

Well, NASA puts rovers on Mars, fixing a cheapo Mercedes should be Peanuts then.

Replacing a perfectly good battery is frowned by many resident rfd mechanics!
I for one would do the same, considering a new battery for a hundred or two, is well worth the price of not having to visit the stealership(s) or drive around town to other shops for diagnostic.

Yes. A fresh, strong battery is a must for cars like your S Class where there's a ton of advanced electronics. Audi Q7 battery replacement should be re-coded into the computer since the system will tell the alternator to charge a fresh battery differently than an older battery.

On another Audi forum, a guy was having all kinds of problems after getting windows tinted. He kept focusing on all the errors and what the issue could be while some kept asking if anything else was done....turned out the tint shop left the doors all open too long and ran the battery down. No problem - they boosted it....except they probably didn't follow the correct procedure or he didn't drive it long enough after picking it up to fully/properly recharge the battery. Bingo -battery replaced and errors all cleared up!

Not surprised. German cars have too much crap running in the background. I use to get low battery warnings on a car I was driving daily (25kms), had to get a charger to top off the battery lol. Car I currently have will light up like a christmas tree as well if the battery is low.

Did you end up sending the bill for the battery to Mercedes?

why would he send them the bill to cover a 4 year old battery that isn't even covered under his warranty? Talk about nickel and diming.

I bet the mercedes mechanics knew it was the battery all along but decided to go the most profitable route, which was fixing things that didn't need to be fixed, billing the hell out of mercedes corporate and ignoring the real issue. Like it's common sense....if you have a bunch of random glitches simultaneously that have absolutely nothing to do with one another...it has to be something other than those individual components all failing at the same time. This is why I do my homework before taking my car in. 90% of the time I already know what needs to be fixed before the mechanic informs me of the diagnosis.

It's funny how this played out. With BMW, the first thing they do is test the battery.

With cars in general becoming filled with electronic gadgets it's a wonder why they removed the battery indicator on the cluster.

My 99 has it and it's helped me pull over at an exit on the highway when I noticed my battery was losing charge due to a bad alternator.
