No they do not shut off as the car would loose the emissions control, unlike a diesel that does shut off completely on the over-run. Of couse this explains why big exhausted chav cars backfire on the over-run as some ( small amount) of fuel is still entering the system. Regards Peter

Ta, they have obviously been making some changes over the years when I wasn't looking. It was quite common to shut the injectors off to save fuel...didn't realise they had stopped the practice, it seemed like a decent idea.

Any developments on the problem, just I've got a very similar fault with my 55reg A3 2.0TFsi.
The car seems to run fine with no noticeable lack of power, but when you press the clutch in whilst changing down gear the engine revs rise to around 2k then drop off as normal. When the car is just ticking over the revs hunt around between 850 & 2000 rpm.
I've taken it into a local garage who ran a diagnostics & found 9 fault codes including misfiring etc. (unfortunately I didn't record the faults). They thought it was the coil packs but this never solved the problem. The fault codes have been reset & I'm waiting for the light on the dash to come back on before taking into another garage? After reading several forums it seam?s split air pipes or faulty MAF sensors are common.
Is it possible to check operation of the MAF sensor?
Any feed back appreciated.

I am having this misfire problem on my 03 S3. My codes also say the same thing, random misfire. I just want to be sure that is the PCV valve, because I don't have it right now, I had to change it, so actually, there is the hose without anything, only a screw to prevent something enters. Also, my fuel pressure regulator hose is broken, And I'm waiting til' monday to get it replaced. Which is exactly the valve you replaced? Thank you. From Venezuela.
