06 c230 sport running like poop shaking badly stalls check engine blink
06 c230 misfiring shaking really bad and died two times on me. The check engine blinks repeatedly, Then it stops. Tried to use my star c5 scanner and couldn’t communicate with the car. Changed manifold and spark plugs and runs better but still doing the same. Anyone have any ideas ? 200k on the car. Also attached is the message popping up when trying to communicate with the car.

what would make you think it’s the scanner ? Works fine on all my other Mercedes. Yeah but I don’t want to just be replacing things not knowing if it will fix it for sure.
not to my knowledge. Bought the car 2 days ago was running the same was told the manifold was cracked so I bought a new one replaced and nothing changed but the old was definitely in bad shape. Flap was cracked and the pivot arm as well. Changed spark plugs was a bit better
i have a 2006 c230 and when i did the system report on it using the scanner it said the signal from component y3/8n1 (turbine speed sensor (VGS)) is not available. i know that i might have a faulty sensor need to replace. would it be hard to replace?

Because Das is not at the point of trying to establish comms and you already have an error!
yeah I’m not sure what you mean. The scanner works fine on 3 of my other Mercedes this only happens on this c230.I’m guessing it’s something with the car maybe they replaced the ecu or faulty.
Any idea why the car doesn't want to talk to your computer? I would start looking there first.
A blinking CEL is a critical problem. Might want to figure out what's going on before you run the engine for too long. Do you know the service history of the car? Wondering if a module died.

Are you connecting with the engine running or with just the key on. My C230 will only connect to a obd2 scanner when the engine is running, otherwise it say comm error. Try spraying some carb cleaner around the manifold when it's running and see if it speeds up.

not at all bought the car last week, was told and have some records of the intake manifold being the problem sure enough after removing the old the flap and pivot arm were broken. So bought a new mani installed stayed the same still ran like ****. Changed the spark plugs and it made it a bit better. Next guess is coil packs as these do seem original. Only thing that comes to mind is the Ecu has been replaced or messed with ?

manifold is brand new. Maybe tb?? Tried with ign on the on position not while running.
It sounds like your problem is a lot bigger than coil packs. To be honest, the comms problem is the problem I would look into first. There is no way to diagnose the other problems if you don't get this one solved first.
I would check the VIN on the ECU and engine block and see if it matches the chassis. There's a way to get the dash to display the ECU VIN. Check online, I don't know the procedure for a 2007.
Next I would check the electrical connectors on the ECU and see if any wires are soaked in fluid or frayed/cooked.

Yes sort out your comms issue first!
Does DAS see battery voltage in the top right of screen?
Does your car have a CGW gateway? Can you get comms with it?
Can you get comms with EIS?

Forget the DAS, just see if you can connect with a standard OBDII reader.
If you don't' have one, borrow one from Auto Zone or oreily, or get a $6 BT OBD interface on ebay and
connect to Torque on a android phone. Any android phone, even one thats not connected to the
cellular.
If you're getting errors relating to being timing being over retarded and such, might be the balance shaft.
Also if the car was out in the rain and there's water in the wiring or electronics, that would cause wierd
connection issues. Let it dry out and try again. Been there done that.
I've learned the hard way to cover the roof and hatch when it rains.
Water seems to get in through the hatch.
I know what you need to fix cuz I misplace mine and then found it I was doing just as
I just did my manifold repair kit and there is a plug in back of engine called intake manifold temperature sensor there are 2 of them
mine was doing the same thing you’re describing til I found this andpice and plugged it in and it ran perfefect
