Hello

My 2001 A3 1.9tdi alh was down on power and driving like a non turbo.
a scan showed a maf fault
The maf actual reading was staying static at 550 even when revs were increased (in 003 Measuring Blocks)
I swopped a maf from a 1.9 skoda and cleared the fault ( it stayed off)
The car drives much better,but when checking the actual amount, the figure only reaches about 500 when the specified is about 850.
Does this still indicate a maf fault?

Regards
Michael
