Just a quick double check that the MAF on the AUQ is 2.75" and the it;s BAM one that's ther 3"? Just hunting down a used one for now is all

Don't go for a used one if you can help it. Typical life expectancy for a MAF is 4 years. After that they are past their best.

I know but for now it's unavaoidable

I asked to keep the old one when mine was replaced.

Recently I cleaned it up with electral cleaning aerosol and swapped it for the newer one for a test.

The old one now works perfectly and I still have the newer one in the boot.
