P0135 009 b1 s1 intermittent open or short to ground

Question

Hi i have a 57 plate vw passat 2.0tdi 170bhp engine code BMR
I recently had my dpf removed with a remap!
This code stated above has appeared but no sign of EML the reason i had it put on the vag is because when im driving at or above 2000rpm power cuts out and returns! Are these symptoms of a lambda or not??
Plz help
P.s the mileage is 140k

Hi there,

No, these are not symptoms. This is more likely a result of a bad MAF.
