Hi all looking for some advice on my Skoda fabia mk2 vrs cthe engine 

if I’m sat at idle for a while and go to off my car will all of a sudden loose all engine power like as if the car has cut out but then after 1-3 seconds come back to life and drive fine it’s really stressing me out now can’t find any other threads on this topic that’s useful please help lol 

The supercharger pulley is a common failure.

 

It has a magnetic clutch on it to engage and disengage the supercharger.

Thanks for the reply would this affect my problem so much though surely it would just be a little power cut but this is a complete engine power cut it and regains everything after a second or two?

Car will still run if the water pump\magnetic clutch goes as the car goes into limp mode and cuts all boost, Shouldn't ever cut out, Just warning lights. Your revs drop to zero then fire back up as normal? No power issues or kangarooing when driving as I would immediately think it was fuel related as HPFP are common to go on these.

 

Any vacuum related issues should in theory throw up a code pretty quickly but never rule that out. Do you have an ob2 adapter and any live software that would let you watch air/fuelling etc?

 

How many many miles has it done out of interest as a failing/stretched timing chain could cause those symptoms.

 

It’s on 43k Apart from that every now and then it’s completely fine no warning lights no codes when plugged in and I’ve got the torque app on the android stereo 

I don’t even see the revs dropped to zero it happens to quick it’s just a sudden engine cut really aggressive if I have my foot down sorry my explaining isn’t great!
