E-Class SBC 10 Year Warranty loop hole
have read on many forms that people that have the SBC system are having lots of problems with the dealers warrantying the SBC System. It seems that that the Mercedes Warranty division has created a loop hole in order to avoid repairing the SBC system for freeeeee during the 10 year warranty period. If you think your carís SBC system still has some of the 10 year warranty. Call your local dealer to confirm.
If you still have warranty the service advisers will always have the tech scan your SBC system to see if itís just a software update or if it needs a new reservoir and in most cases its just the reservoir and the software update. Then they will turn around and tell you that reservoir is not covered under the 10 year warranty. Itís going to cost you about 1300.00 dollars for repairing the reservoir, and if you just want the BOSH reservoir part itself last time I checked it had dropped down from 700.00 to 500.00 dollars at the dealer.
For those of you that might still have warranty call the dealer to confirm. If you do, before taking the car in, buy a scan tool on Amazon or ebay and scan the SBC system on your own. I found one for around 130.00
Checks to see if you get code C2131 and Code C249F, if these are the only codes you retrieve you need to damage the motherboard on the SBC system itself. Otherwise the dealer is going to charge you just for changing the reservoir and updating the software, the cost for that is around 1300.00.
The C249F is a software update that the SBC system need in order tell the SBC system how much life it has left. You can set life cycle to 25%, 50%, 75% or even 100%. The scan tool I used is the AUTEL EBS301 SBC Scan tool. This tool will automatically calculate the new miles as when the SBC light well come on the next time. Also note if the dealer wants to be a dick with you, they can set the life cycle to 25% just enough so the right RED light comes back on again and recharge you more in the near future. They can easley calculate this by the how long you have owned the car and how much mileage you have driven it.
Good luck and donít get pried off.
