this number is ***** the engine space plate. The is another 17 digit number [Getriebe] but it only in the manual.
It does appear to me that this car has a locking solenoid [ due to the chatter when the locks come on- [not an air system] but as I have not had the door card off I wait your expertise. All the other locks work perfect.
