Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi Darrell, there are no current fault codes, only stored events. You've got some ABS events and some cluster communication faults that are probably affecting the cruise lights but there is nothing there to go on. I suspect that the ABS events are causing the problem. When an ABS event occurs such as ABS engagement or a speed sensor glitch it would probably flash the lights to alert the driver. It's very common to see cluster communication faults even when there is nothing wrong. You should erase all fault codes then rescan the car the moment the cluster acts up again. If your one touch open and close roof does not function you will need to normalize the roof.
I use some pretty expensive scan tools. I don't know what the least expensive tool is out there that can erase codes in all modules. I know that Autel makes some scan tools that can do it I'm just not sure of which one you would need. I would contact Autel and see if they can suggest something.
Hi Darrell, sorry for the wait I have been buried at work. I would not perform a cluster reset as I think you will then need to re-input the variant coding. You can cause all sorts of problems with the scan tool if you get into changing coding and such. I would be careful. In most cases the scan tool will warn you before you go too far. Software upgrades are done through the Mercedes dealer. You cannot really check if what you have is current. Usually software is updated if you are having a problem with a particular module. I ran an VMI inquiry and there are no open campaigns and recalls.
Definitely a sign of a bad battery. Especially if you get the warning when you first start the car and it goes away after you drive. You should get the battery charged and tested. Once in awhile I see an original battery last that long.
I use the Interstate AGM battery because it has a little better warranty than the Mercedes battery. They sometimes have the auxiliary battery as well. If they do not have the aux battery I get them from the Mercedes dealer. Pricewise they are about the same as Mercedes. The Mercedes OEM battery retails for $247. The aux battery is $167. Compare that to what Interstate charges.
It wouldn't be a bad idea. The aux battery is primarily for the electronic braking system. It would be nice to start with two fresh batteries.
Yes, the recommended battery for your car is the AGM.
I think you have an instrument cluster fault causing the LED's to flash. On the B1211 it's saying your heated mirror element is bad or there is a harness fault.
On your maintenance you could also do air, fuel, cabin filter, coolant, power steering fluid and spark plugs.
