Did you have the same problems mate

Yes mate wasnt boosting to what is was mena only reached 1.6 instead of 1.9

Could be a leak aswell mate, what happened to mine.

Yeah but way would it boost to 2bar then drops off to 1.5bar?

I have got a video of it doing it but don't know how to upload it on here

What's causing it to do that

Possibly worth looking at replacing the vacuum box located on the RHS strut, it contains the N75 which may well be playing up.

Yeah I have a fully working vacuum box for sale for the fabia.

It's got a brand new on mate

Oh ok, actuator set up may be off, there's an output test you can do with VCDS but I can't remember it off the top of my head.

Could be anytime type of leak from any of your boost hoses mate.

Get a test done.
