Is the QC Mark label to camouflage the specs of the infineon?

There are 2 different VAS 5054A for sale- one vas5054a comes with 32F40F and the other comes with 16F40F.

32F40F (on Chinese VAS5054A)

32F40F better than specs
16F40F original
16F20F bad return or sell for parts.

The result is

16F40F is slower than 32F40F.

A bit ridiculous! But the clone with 32F40F does run much faster than the genuine with 16F40F

If you just look for a working unit, either genuine or clone, VAS5054A with 32F40F can be a good one. it’s tested successfully, confirmed to work no issues with odis service 4.4.1 and odis engineering 6.7.5
