Filter VR-sensor to MAX9926
Let me first than you for your help and suggestions. 

After a bit of trial and error I found a solution. I added more resistance to the shunt resistor R4 and also added a resistor in parallel with the cap C8. This lowered the voltage over all which made the noise so small the MAX-chip don't pick it up a signal. But the proper signals is still of enough amplitude that they are picked up.
