Mazda 626 Diesel: Power Loss & Jerking

Okay, I really need to vent my frustrations now.
After 4 visits to the workshop and replacement of the mass airflow sensor, oxygen sensor, and temperature sensor, there is still a noticeable lack of power and significant jerking at approximately 1800 RPM.
The car is back at the workshop, and Mazda Leverkusen (authorized dealer) is now handling the issue.
Despite the mobility guarantee, no replacement car was provided, even though I am always allowed to leave my car there.
The mobility guarantee is only valid if you are stranded and are 80 km away from your place of residence.

I'm gradually getting tired of hearing that Japanese people don't have any problems.

They only cook with water.
Given the sheer number of cars sold in Germany, individual defects are less noticeable compared to the extremely popular VW TDIs.

So, I would think about that again. The loss in value that you are currently experiencing is likely to be significant, and I doubt whether you will actually save any trouble.
