On RU-vid every job looks easy... But reality is different.
I hope that with this video you'll be able to do the job, without breaking anything.
This is a C200 CDI w204 facelift model. Car showed P245328, P245414 and P246309 trouble codes.
Sensor from Bosch costs about 35 euros. You can easily spare 250 euros doing the job yourself.
Good luck :-) and please subscribe to support my effort :-)
