Hello there guy's, Well i have a 2007 passat 170 and had lots of problems with starting and smoking and lies from vw.

All i'm left with is power surging at low rev's thats intermittent, the odd hard start up & hears 1 for the vw master's. Its had a dpf delete and remap at some part in its life and some how managed to delete any engine faults & code's, for example disconnect the maf sensor vag com scan it no fault code's or eml light, ever for a drive for few hours no light, any ideas how they've done this or whats the power surge fault ? thanks guys

does the em light come on when you first turn the ign on, then go off.

Hey zollaf yes it does :)

maf may not be the best test, what bout if you unplug the cts for instance, or fuel temp.

Probably: DPF delete wasn't done properly and some muppet has erased fault codes in a block. not just dpf codes.
