I would of thought it wud be why it's cutting out. I'd start by ringing seat and asking them about the part. Start by finding the valve first. If u type in seat p0444 on google u will find a pic of it on a Audi forum then find the valve n check the wiring I think there maybe a fuse involved too so check them. But I've never come across it so ant sure really just shat I've read in the last few mins
