You might need to simply disconnect the battery for 10 mins and do the usual like set the clock etc afterwards but although the ecu will have stored the code it should start from scratch, first doing a TBA (throttle body alignment) - lots of whirring and clicking, when thats stopped (ign on after reconnecting battery, dont start engine just ign on) the engine will be ready to start and hopefully since all is well the CEL(check engine light) should not come on.\015\012\015\012\015\012At worst, see if someone local has vag com or a hand-held OBD device that can reset the CEL and if it just comes back on, the fault is solid.

Did you mean you connected the original maf back up or a new one? If its the original and the light only appeared after disconnecting it, then the ecu mustnt have realised it was faulty, and only noticed when you pulled the plug, a reset should clear it no problem, but has you original fault returned after putting the maf back on or has it now gone away? Might have been a bad/dirty connection now made good, or if youve cleaned it, and its working fine, the CEL will be a dummy from the time it was removed so reset & your good to go!
\015\012many a times while replacing the maf the wires beside the sensor gets disconnected or loose and this makes the problem.so check out the wirings.\015\012This will help. Thanks please keep updated.\015\012please do rate the solution positively .thank you for using fixya
There is no setting for the MAF, the MAF reads the reads the quantity of air entering the engine, this reading is constantly varing with the throttle position and the density of the air, the resding that the computer sees is from 1.00 volt to about 4.75 volts, 4.75 volts would be wide open throttle, one volt closed throttle, this is called the MAF signal.
