Major Electrical malfunction Tow car to dealer without shifting gear and more
Finally have the nightmare scenario 2011 R350 70Kmiles (115k Km)
Washed the car yesterday, put it under car shelter. Today opened rear door and all hell broke loose
Red flashing dash "take car to dealer without shifting gears" beep alarm too
SRS malfunction
ABS malfunction
Tire inflation warning malfunction
Cant start car.
lights work
heat/blower seemed to be on (tried to turn it off)
cant lock doors.
Cant turn stuff off
probably other problems.
What the hell?
No water in air intake underhood
Possible water from snow melt under drivers seat?

Update
put battery charger and things are back to life. Have door lock , rear hatch and other control
Voltage without charger is like 6 volts!
Battery is charging at maximum setting of 15 amps. Hope it is not a short somewhere.
but transmission no shift and other faults still there. Will wait till charged if it does charge up.
I had similar problem a few years ago with honda..Shorted alternator. no amount of charging or boosting helped as any attempt to charge just went thru short.
So car started and battery holds at 12 volts, so no direct short. but still transmission fault. Auxilliary battery?

if it was just a very dead battery, and I am now charging it, will the auxiliary batter recharge also? Will the "take car to dealer, do not shift" warning go away?
i read in another post that disconnecting the main battery for a few minutes will reset things.

Overnight charging has solved the problem. had a U0155 code, seems it is unable to communicate with instrument cluster but not sure. my alldatadiy does not have that code .
my generic code reader may not be specific. However, engine light on too.. so a obdII reset did the trick
Now just to see what caused the battery do die in one day. will bring it in the garage and test the battery.. Alternator seems to work fine.

No, I did not find out what caused the power drain to kill the battery in a day. Will see if it persists.
I did test the battery and it showed just on the edge of weak to good.
So same problem this morning Battery drained overnight in 12 hours. Purchased a new battery. Great deals on Group 48 AGM at canadian tire. $240.
Still will troubleshoot for battery drain. Have to remove seat anyway to get to battery terminal to clamp ammeter.

So Good news, Bad news. Good news is that I changed the battery, and measured the quiescent current to be under the 50 milli amp level as per diagnostics.
The bad news is that I did not find any problems. Even the battery tested not so bad, not as good as the new one but not "weak" So still crossing my fingers that it was the battery. If there is an module that is causing an intermittent current drain fault, this will happen again.
MB wanted C$120 for the auxiliary battery. BTW it is not a UB1213 C1212... Those are just a tiny bit narrower. Standard ones also do not have the same connectors. The MB battery has a .250 and .187 connectors. The replacement batteries have 2x 0.187. I almost purchased one at our local Battery Expert store. I wanted to get a quality replacement. They only had their housebrand, "Enerwatt" imported by a local distributor from china. Narrower, no name. wrong connectors. made in China.. To many strikes. I put the original one back. I tested it at 2 amps and voltage was still over 12V.

Problem re-appeared last night. Initially as ESP and tire inflation warning failure. Was able to start and drive car home.
Then next morning complete failure again. Yet battery is at 12.4 volts. Charging showed 15 amp draw. Will charge again..
perhaps it is the ESP system that is pulling the rest down
Will bring to dealer.

So... Update
Alternator replaced: regulator overvoltage and over current. The thing tested at 300Amps. So apparently modules went into overvoltage protection.
Hassan at European Autowerks did a great job, very pleasant to deal with. There was a Bentley in the lot for repair and a lovely 928 too! I guess he is trusted!
Hopefully that was it and no faults will come back over the next days.

On wednesday when picked up my R... I dropped of my 2005 C240 for rear suspension..
When I picked it up today there was a lovely Maserati Khamsin on the lot.. Gorgeous old thing. https://en.wikipedia.org/wiki/Maserati_Khamsin
Back in the day when cars where like women.. so sexy and sensuous!

Yeah, you'll see a lot of nice older cars like the maser as well as newer ferraris and lambos. You'll also see some rare old fiats & alfas with a slew of porsches, audis, mercs, etc. He used to work on P.E. Trudeau's Merc 190 cabriolet until it was sold. I remember seeing it there often. He charges a fraction of the price that Ferrari or John Scotti would charge for work done on exotics. I'm glad you found him and I'm sure you'll be happy with his service.
