Mk3 Leon 184 Code- 00531


Apr 21, 2005
Afternoon Everyone,

Can anyone shed any light what this error could be caused by?

Just scanned it on Carista and I get 00531 ( Mass air flow sensor voltage) if I clear it the fault reappears as it can not be cleared.

the car is boosting fine, no EML and no limp mode. I looked at the MAF physically all connections look ok from just looking at the them.

Thanks in advance.
