Thanks buddy!
I'm only getting the estimate/quote.

But the bumper cover is arriving tomorrow!

Dave, Is the H8 AGM battery the one under the hood?

the aux battery is under the dash on the driver's side, if I recall correctly. You should still scan the car to see what codes come up. Even though the CEL turned off, the code will still be stored. And no, "crap" doesn't built up in the "cats" if the car sits for 4 months. Where did you even hear that lol. Check the code instead of guessing.
ABS light was on because you were forklifting and dragging the car around and the wheel speed sensors were confused. You can scan the ABS codes as well, but you need an actual STAR DAS system to get all the codes from the car. Glad to see it runs and drives anyway.

Big Congratulations to you buddy. You survived the worst in my opinion. Car could have started with engine, suspension etc all gone...making it a total kaput.
should be smooth sailing from here. props for staying optimistic.
i suggest you get the car scanned to see of any codes stored, charge the batteries and get fluids changed.

nonetheless, be aware the S class is a high maintenance *****...always prepare for the worst since you don't have any warranty to cover repairs.

There are 2 batteries. The underhood battery is the "starter" battery and the trunk battery is likely an agm ( absorbed glass mat ) battery. If you have an agm battery charger (I'm assuming it's an agm battery) you can charge it.

That battery was depleted as the car sat a long time, it's possible it will be ok but if it's original, the deep cycling could easily kill it. The battery can be tested, basically if it's gone it will still charge but it discharges really quickly.

His aux battery is kaput and needs to be replaced. The red battery light will only come on and stay on if the battery is no longer able to hold a charge. It is likely the original at at least 9 years old.

To get to it, remove the 2 screws holding the net tie downs on the trunk floor. Remove that bottom panel that those screws held down, then reach down to the bottom of the panel that lines up vertically with the rear seat and pull hard toward you to remove the panel. You will then see your accessory battery on the right, along with a host of other computers and electronics. Unbolt the tie down strap, remove the positive and negative terminals, then gently work the battery out of there. Getting it out will be the most difficult part as it's packed in there pretty tight. It is also vented to the outside of the car on the right side, so be sure that you save the plastic vent plug for the new battery. Be sure to take a picture of the battery before you remove it so you can see how everything lines up and how the connections are made.

If you go with a non-oem battery, make sure you remove the vent plug on the right side and test fit the vent from the car before working the battery in there. It may not fit, so you may have to take out the little sleeve inside the vent hole to make if fit properly. Putting the new battery in is obviously the reverse of taking the old one out. All in about a 20-30 minute job.

About two minutes after I turned it on my MIL popped. I think its because of all the crap inside the catalytic converters made it pop.

My battery is low. My driver side speaker is blown. My rear right tire is at 15psi. 15726 miles since last oil change so it needs one.
I may have a spare drivers side speaker module. Front door correct?

Okay, so I have been a member of this forum for a pretty long time, and this may or may not be my first post . I honestly can't remember. Either way, I've been subscribed to this thread, watching this go down like a failed rocket launch. But somehow, the car started. I didn't think it would. Everyone in my house was cheering you on like it was the first moon landing. Haha. Thanks for the entertainment.

I like how after busting your chops for a while, both Mike and Dave are coming through with help.

And here's a thumbs up to you for letting it roll off.

For god's sake, make sure the car comes out looking like new!

Nobody can say that I didn't try to talk some sense into him about this ill-conceived project. I still think it is a very bad idea and won't turn out the way that he thinks it will. But since he's insistent about following through on this, I can only hope that he will do it right for the sake and safety of himself, his family, and other drivers on the road. He just needs to be aware that he likely won't get it done, especially to a high standard, on the limited budget that he has set out for himself. Not to mention, all of the other issues that will be rearing their ugly heads in the not to distant future from buying a 9 year old S-class nearly 80k miles. But all that said, I hope his project turns out well and I'm looking forward to seeing how it progresses. And I hope that he starts an all new thread to detail all of the work on the car from start to finish.

Well this blows. I had that stupid module sitting in the garage for three years, but when I ordered the C I went thru and tossed a ton of small S stuff that I figured wasn't worth Ebaying and I'm pretty sure it's gone. Sorry. If it turns up I'll let you know. If all else fails they show up on EBay for around $150.
