Thanks guys, this is good news...and bad. SK re FAIL I mean car running fine then occassionally jerk/stall/run OK/jerk stall etc. Fault codes show AFM. Examination reveals it has had some physical grief (but was previously running fine as stated). Tried cleaning with contact cleaner down the bore onto the element but to no avail (running stock airbox anyway). Replace with another one in A1 condition and all OK. 6 months later same thing, fault code shows AFM.
I agree there's not a lot to go wrong - that's why it peeves me.
It might be the connections I guess, do you know where I can source some aftermarket plugs to splice into the loom?
Thanks
