Hi all,
Apologies if there is already a post on this but everything I find relates to the common issue with the sunroof. Car is an '09 A4 (B8) Avant S-line 2.0 tfsi quattro with NO sunroof.
I've got what is now a slow water leak into the cabin. On a squelchy rear footwell being reported by our 4yo, I initially removed the driver's seat, lifted the carpet to expose a small pond deep enough to just about reach the bottom of the electrical harness housing under the seat. Yep, the one with the airbag connector block. Water is clear, no fragrance to it and occurs when it rains only, so points to rain water ingress imho. After sponging it all out it became evident water was trickling in from in front of the dash somewhere as the sound deadening spongey stuff under carpet and in front of pedals was all sopping wet. So far I have (in chronological order);
I am at the point where I believe the only way of conclusively investigating further is to remove the dash but I can't find a guide anywhere to do this for the B8. So I'm open to thoughts and if anyone has or can point me to a guide for removing the dash panel? Has anyone without the sunroof had this problem?

So far I have (in chronological order);
- Cleared scuttle and unblocked drain holes both sides (removed seemingly pointless rubber grommets)
- Replaced windscreen (by professional fitter) - sound deadening at top of dash was very wet, A pillars dry. This improved but did not eliminate the problem.
- Got hose on scuttle, water streaming in when over ECU so replaced ECU compartment and lid (rubber seals looked perished)
- Replaced slightly damaged rain water deflector - clips into bonded trim at bottom of windscreen then connects to scuttle cover.
