Slow laggy LCR with VAG-COM code=HELP!!!

[cap r 225]

As above chap's, i'll post this in the vag-com section aswell but if there are any techie types in here that can help it would be much appriciated.

I noticed a few weeks ago that the LCR didn't feel quite right, spool up seems to take longer and the boost doesn't seem to peak as it used to. My trip computer and average MPG all re-set themselves every time the key is removed from the ignition? MrDave got Vag-Com on it for me and it threw this up

We cleared the fault and it was fine for about two weeks, i now have the feeling it's back again
It's probably worth mentioning it was two very cold day's this has happend, could it just be the cold weather messing around with the ECU? As my work's van has played up a bit with the engine management light lately aswell?!

yeah, i've had a look around and all seems ok, she's only done 33k. I had it on Vag-Com again today and it had thrown some different code's up. one being the brake light footswitch. I don't think i'm gona worry so much now as i think the cold weather is just playing with the ECU as i have read on another thread regarding the N205 valve. I'm just suprised that these code's do make the car a little sluggish. I'm also thinking i might have a dodgy dumpvalve so i'm gona replace this
