Greetings, I own a 06 Cls 500 amg package. The vehicle was sitting for 2+ yrs. First thing I did was get a key made through a black smith. Bought 2 new AGM batteries front and rear . Then I got suspension parts replace front wheel bearings (beck arnley) with mb dealer inner seals..Got the car back frm mechanic fine. It drove for a few days. Then I upgraded the amg 18" for "20 rims. Rims were installed everything still fine and working. So I decided to take it to work that day and also decided to go against my word on only handwashing the beauty. Smdh. So as im going thru the auto wash suddenly my radio music clicks out then back on twice while showing abs esp brake tire headlight malfunction/unavailable tightening up the steering wheel. Next day I notice navigation had unavailable message, I would like to think it failed also that day. Not sure cause i didn't check then.

So here's where I'm @ now. I open the hood and seen the driver side sam box was half way open.(ouch) During inspection I seen no signs of water even after opening up the Esp Module. Passengers side floor board was dry. Rear driver side trunk was dry even tho a rust spot was on the navigation dvd drive that's not ejecting anymore.(weird) Checked the abs light and everything erased right front sensor rpm sensor abs module but the front left sensor L6 stays. I had the mechanic check his work and diagnosed. He replied that my abs module was the issue being that he switch right to left sensor and left still @ fault. Instead of going with his recommendation I've read similar issues on forums that stated it's the ESP Module. So I purchase a used one and low and behold the abs light was off upon start up and things were back to normal @ least intil i drove over. 8mphs then the same lights came on. Checked code and it's front right sensor L6, (note) the used ESP Module comes frm a right driving side car in UK. One thing I notice is my old esp module wouldn't cut the abs light off none unless your trying to delete it then it works fine briefly until it comes right back on. The used module will cut the abs and other lights off after cutting the car off then back on after sitting.(hmmm)

Tire size front 245/35/20 rear 285/30/20
Rims front 8.5 rear 9.5

I kno this is one big cluster f@#? .Sending this out to anyone who may had experienced this situation or have a solution to fix. Thanks n advance

 

Update: I'm suspecting the SBC module and I have a appointment with the stealership tomorrow. I asked them to look @ my abs module b4 when I was getting trans serviced and after I told her it wasn't the front wheel sensors that the code was saying, It's the ABS. She calls me when my car was done just to say "My technician said It's the front speed sensors". Then she goes.. "It's $1000 to replace the sensors" Lol. Ya Ok.

So I recently call them and I told her I suspect it's the SBC ABS module and I want it checked. So of coarse $200 for the scan check. Strange thing is she just called me tryna reschedule but after I protested they're other employees that works here, she puts me on hold then came back on the line and said her technician wanted to know if there was fluid coming out of the SBC unit and lo and behold one day I was tinkering after the engine was running and I decided to unplug the SBC harness and seen hydraulic type fluid coming oozing out of the female port. Hmmm.

So she said bring it in and there going to give me the warranty for the SBC ABS module. After messing with the used esp and it cutting the light off I was thinking it just needs to be coded. Now after seeing that fluid I expect what the first mechanic told me, It's the ABS.

Welp, I'm going to drop her off tomorrow and give a update on the outcome.
