My W168 is missing on cylinder #2. I'm looking for information on how to troubleshoot the ignition module/coil before I purchase a new one.
I recently replaced the starter using the top replacement technique. After reassembly, cylinder #4 was missing as per ECU code P0304 (I believe). I reattached the module connector to ensure a good connection, cleared the code and then it switched to missing on cylinder #2 with ECU code P0302. I again ensured there was a good connection to the module a couple of more times and each time I start the car is comes up as missing on #2 (P0302).
I replaced all four spark plugs but still code P0302 is coming up.
Can anyone assist with troubleshooting procedure or point me to a resource online with information?
