    Hi i have got a problem with my A3 1999 1.8T QS it feels like it is running on 3 cylinders but its not and there is hardly any boost, I took it to Audi today and they have said that the Air Filter Charge Pressure Sensor has been disconnected, Is this the N75 as that all looks fine i cant see anything else that looks disconnected. I have checked the SMIC and the hoses are fine. I have had the car remapped and replaced the Recirc valve with a Forge 007 and put a K&N filter on, Also i have tried a different MAF and its not that.
    Any Help would be greatly appriciated.

    Think they may mean the MAP sensor thats in the top of the SMIC (drivers side)
