Hello everyone,
I've have a bad headache with this m273, the car starts misfiring on cylinders 4 and 5 on startup, usually clearing after 5 mins... Curiously it never occurred on the first start of the day.

So far, spark plugs have been replaced, fuel pump was tested, ignition coils were tested, compression test done and ok, camshaft magnets replaced...
This car was also manufactured after the idle gear problem was fixed from production.
It's has been to 3 different mercedes mechanics and I don't know what to do anymore.

computer shows these codes before the camshaft magnet replacement :

-0275 Continuous camshaft adjustment (LEFT): Incorrect position of the intake camshaft (P0021)
-0059 Incorrect position of the exhaust camshaft (P0014)
P0014 MERCEDES-BENZ - 'B' Camshaft Position Timing Over Advanced Or System Performance Bank 1
-P0024 MERCEDES-BENZ - 'B' Camshaft Position Timing Over Advanced Or System Performance Bank 2
0063 Incorrect position of the exhaust camshaft (P0024)
- P0301 MERCEDES-BENZ - Cylinder 1 Misfire Detected
- P0304 MERCEDES-BENZ - Cylinder 4 Misfire Detected
-P0305 MERCEDES-BENZ - Cylinder 5 Misfire Detected
 
Apologies for the long post, at this point I'm thinking of going to court to try to annul the purchase, since the car has been purchased 3 months ago and this started a week after the purchase.

Kind regards
