Maby some one can give me a clue
My 500e-93, has way to high hc.
We find a issue whith the lamdasond,
baugh a “original” Borsch.
The hc was lower, about 469ppm,
before we change the lamdasond it was about 540.
We check the engine whith the Borsch diagnostics,
and we not find any “strange”.
The car is running very well.
Someone give me a clue?
Best Regards Niklas
