Yet more advice on waterlogged b5s.

Seeing as this was the first decent day of weather in somerset this year,I took the opportunity to cure the water leaks in my avant,I knew the rear washer pipe had become detatched from the joiner behind the passengers kick panel,simple job, 5 mins max.next battery out to clear the drains under battery tray and servo,sure enough full of all sorts of leaves and crap,replaced pollen filter at same time,now all this is obvious stuff,thinks to myself while I am at it will run the pipe from the boost gauge I fitted just before christmas,(couldnt finish it at the time ..rain stopped play)so takes the top of the ecu plastic box to route the pipe only to find the 10mm nut holding the box down from inside was missing!!massive entry point for rain!!a bead of silicone and a new nut and fingers crossed it should have stopped all ingress of water,also behind ecu box was full of crap so even if you have cleared your drains out, if you neglect to clear the rubbish behind this box it will just wash down and block them up again,hope this helps somebody,because i know b5s suffer with this problem.
