Mass Airflow Sensor

[Ben-ibizaFR]

Anyone know the location of the MAF on the 1.2TSI ?

CHeers in advance

There isn't one.

It knows the engine speed, engine displacement, temperature and manifold pressure so it can calculate the mass flow from these.

There are actually sensors either side of the throttle valve.

Clever ! Thanks for the help ! Don't suppose you know what the pipe is that comes off the pipe from the air box to the engine ? Not that in going to touch any of it, just interested !

Not quite wih you.....
There's a pipe from the airbox to the turbo at the front of the engine. Then there is a pipe from the turbo over the rocker cover to the throttle valve and air-water intercooler at the back.

The pressure sensors are between turbo and throttle valve and also between intercooler and engine (I think). Each pressure sensor also incorporates a temperature sensor.

All very complicated and the 1.4 twincharger is even more so!

Think he's on about a small pipe that is joined underneath the air intake pipe at the air box

Appreciate the help guys ! You can say that again about it being complicated haha !
Il try to be more clear from the air box. There is a air pipe that takes clean air to the turbo/engine. In the middle of this pipe is another. Almost rubber bendy pipe that comes of at a T and goin towards the engine. Could it be the crankcase breather pipe ?

I dunno guv!

No problem mate, managed to get a picture non the less, it's the small rubber tubing with the vag writing and Germany written in it.
