anyone used a baileys been given one been told not to use as messes with fuel but cant see how? thanks

If it's full atmos then yes it will mess with the fuel. The 1.8ts ECU uses the MAF to measure airflow up and down the intake. If it releases the full pressure into the atmosphere, the MAF senses this and overfuels to compensate.

I think that's how it works anyway lol but I know a full atmos is not a good idea on these cars.

I was using the DV26 atmos valve recently - apparently worked fine with no fault codes at all. But it will cause slight overfuelling and a reduction in MPG, plus the sound got annoying so I went back to the full recirc. DV30, which is still pretty loud and is fine for me, plus the 1.8t was designed to run that way.

Full atmos valves can cause CAT failure, bore wash, fouled plugs and error codes for pressure drop and lambda probes.
