What prj said. Also log ps_w and compare with actual boost.

Sorry I haven't been active in a while guys. Been busy with real world stuff. I unplugged my MAF the other day and it runs basically the same if not a bit smoother. Been getting some hesitation and surging here and there before I unplugged it so I'm pretty certain it's dying. Bit of a strange one though, I've driven the car a few times since I unplugged it and it still hasn't triggered the EML yet. I thought it should trigger as soon as I unplug it? Would explain why it hasn't complained about the MAF though if the EML for it doesn't trigger.

PS: I put the engine back together and the timing is all correct. I replaced the belt so I had the bottom timing cover off and made sure the witness marks were all lined up.
I'll plug it in to see if has developed any error codes. Everything else is fine. no intake vac leaks, most hoses replaced with silicone and a healthy new 710p dv from a trusted VAG supplier.

Edit: EML for MAF finally triggered. Just took a few runs out after unplugging it for it to come on. It came on when I went out earlier. I'm going to try and get a log later to see my fuel trims. I have free vcds lite so it only measures up to block 25. Does anyone know if the blue FTDI cable works with vcds?
