There are 2 Lampa codes...1223 and 1224. What is the difference between. The 164B shows 1224, the 164S shows 1223. I'll start looking for air leaks, but am interested in knowing if there are more details on which each means.
I had a CEL lately and the engine shut down a few minutes later.
Thanks to Alfisto Steve, I learned of the Motronic Diagnosis and performed the procedure and received the 1-2-2-3 code.
Would that problem shut down the engine? By the way I was able to restart the car and drive on after a couple of hours.
