Run the vag-com for first time today

Hi guys, I ran the vag-com for first time today, and it is saying that my MAF reading signal is low?
My oxygen sensor reading is low.
I know where the MAF is and I think I will try to give it a clean with some alcohol or white spirit before I look at buying a new one, but I have no clue where the oxygen sensor is?
Can someone shed some light on it for me please
P.S. how much would one cost???

Dunno about o2 sensor, but try and use electrical contact cleaner spray on maf (from maplins or the like) as its safe to use and doesn't leave any residue. Mafs are pretty delicate so you don't want to be touching them with your fingers, rather use a spray.

Yeah IPA is good for cleaning electronic components and can get it from maplins etc

thx guys, I'll pop to maplins over the next few, hopefully the MAF sensor is just dirty, recently put an induction kit on and wondered if that could have something to with it??

It is an oily one it will of knackered your maf... K&N are notorious for this...

o2 sensor is the lambda sensor in the exhaust downpipe... 2 sensors pre cat and post cat.

if its running lean duet to nacked maf, the sensor will read this and chuck a code.

oh right ok, so once i fix the MAF the lambda sensor may read as ok again or is it likely to need replacing.
The induction kit is a ripspeed one, but I'm waiting for a green stuff panel filter so I can put the box back on, I hate the sound from the induction kit.
