Do you have any drivability symptoms ? I was driving my car to work this morning , upon a hard acceleration, check engine light came on and felt loss of power , check engine light started blinking ( misfiring ) long story short , got towed, when loading up on the tow truck, a bunch of smoke came out the exhaust , I have cyl 1&3 misfire codes / P06DA00 / and P1CEF85 which is your code .

my car at dealer now, they are trying to squeeze me more $$$ for diagnostics.
STEALER dealer.
I need to contact MB customer service. But I read from a few posts with no help.

You will need to do the follow.
1. Remove and install New Injections - If this is a C300 then you will need to remove and install 4 new Injections and not just 1. You could do one but I would not do that.
2. Replace all spark plugs
3. Change oil, 2x to remove any gas from it.
What you have wrong is that the ECU is seeing the Injector in Cyc 1 is staying open more than it should. If you do not do this soon, the injector may put do much gas in Cyc 1 and harm the engine.
