Airflow Meter S40 T4, Help !!

jamie012002 · Jun 1st, 2007, 12:33

Dear All

I've got an S40 T4 1999 that lost all power, basically drives like a basic 1900cc with no guts at all !! more like 20 BHP not the 200 it should be. Took it to an Independent Volvo Grage who said the diagnotics said it was a faulty airflow meter. They changed it for me, but when I picked it up this morning it's still the same. !! I've got to take it back on Monday for them to have another look, but wondered if anyone had any ideas to maybe save some labour charges with them looking to find the fault for hours !! It drives fine, no smoke, no oil on turbo no misfiring, but just got no power !! Did struggle to get up to 70mph though, like it's running in some sort of limp mode.

Any ideas ?

Cheers
Jamie

read the codes and see what they say.

then hook up a boost guage and see if the turbo is boosting.
