Faultcode 16486 & 18265

[SilverS8]

Hi.

Yesterday i was just moving the car a few meters and noticed at startup(cold engine) that it really threw out a cloud of smoke, grey-ish and it smelled petrol all over. The smoke stopped immediatly after starup and the car seemed fine.

Had to move it again today and the same thing happened so i took her for a ride and no smoke and car acting all fine.

A scan revealed theese codes.

Address 01: Engine Labels: 4D0-907-560-AVP.lbl
2 Faults Found:
17978 - Engine Start Blocked by Immobilizer
P1570 - 35-10 - - Intermittent
16486 - Mass Air Flow Sensor (G70)
P0102 - 35-10 - Signal too Low - Intermittent
Readiness: 0000 0000

and

Address 02: Auto Trans Labels: 01L-927-156.lbl
1 Fault Found:
18265 - Load Signal
P1857 - 35-10 - Error Message from ECU - Intermittent

After reading some threads regarding thiose codes i'm wondering if the code from the auto trans is caused by the MAF code above?

My Maf was cleaned not long ago after some other issues fixed by changing all the vacum lines
