Water ingress to cab :-(!!!!!
 

Hey guys, just back from a drive and noticed the windows were steamed up after collecting my sons comic from the shop, alarm bells started! First place to check was passenger footwell.........yup, soaked!!!!

Any ideas what's causing this to leak? It's going into garage next week for work so a wee pointer would be great!

TIA.......:(

Blocked drains at the bulkhead

Holy moly I thought I was doing well finding this................

The first thing to do is decide (not easy) which of the 3 or 4 main suspects is the actual source.
If it's ONLY the passenger side could be Botangs hole.
If you hear "sloshing" going round sharp corners it's probably the aircon evaporator/condenser drains (orange drains)

Take the main front carpets up both sides and look underneath; they can absorb an ENORMOUS amount of water. :eek:

As noted by me in one of those threads, if it's the orange drains it's just as easy to take them right out and clean thoroughly rather than blow air through them which doesn't remove all the "crud". ;)

I hear ya fella, problem is I can't get anywhere near the car just now as its hammering down here and I've no garage to stay dry! :(

Right got it started, removed the side trim at the passenger tunnel side and located the big orange bit! Removed that and no water came :Confused: Does this mean its not leaking from here???? :rolleyes:

Difficult to tell.
Take the orange drain out of the car and see if a trickle of water into the open pipe comes out of the "valve" end.
Either way clean out the valve with warm soapy water and check it works OK. Then soften it in VERY HOT water before easing it back into place.

Unless it's 100% OK before cleaning I'd do the other side too.

I would also suggest you do the drains either side of the transmission tunnel, they are the ones you need to attack with the air hose, or if you can get it on a ramp I think you can access them from underneath

good luck

If you mean the scuttle drains, Daviesbike (I think) recommended loads of hot water and detergent on those. There's a complex process with bent copper tube on Audipages IIRC.
(luckily mine are free flowing)

If it is the scuttle drains then you need to clean out the scuttle before attempting to clear the drains

The car has been parked up since the weekend and its rained constant here so I thought I'd have a wee look to see the damage....................

NOT A DROP OF WATER HAS ENTERED!!!!!!!................

So it must be when the car is moving?!?!?! :( Its going away next week to the garage so I'll ask them about clearing drains, A/C pipes etc! :)

That points again to the aircon drains as a most likely cause.
One test (that I used effectively) is to turn the aircon off (i.e. Econ mode) for a few days and observe.

I had this problem which appeared not long after buying my A8 in December 2011. Water would literally gush out from the console side trim and all over the better half's feet. Also had water spitting out of the dash vents front and rear. The longer the journey, the worse it was. I had the trim stripped and was shocked at how much water came out of the orange tube. Drained it several times. Got my local garage to investigate, and they cleared the air con drainage tubes. Been absolutely fine since it was done earlier in the year. My dad's old A8 (PF 1996 N Plate) had the same symptons way back when he had it, but we never knew what caused it at the time.

Right guys, my mate has been on this today and I'm now asking for your advice. He has cleared the A/C pipes at the side of the gear lever, he has cleared the pipes under the arches and the botang hole has a grommet in it.

When the boy aims a hose at the windscreen the water is running into the scuttle and is still dripping like a tap into the passenger footwell! :Confused::(

Any ideas now so I can pass it onto him???? :cool:

must be scuttle drains, you will need the brake pipe on an air hose trick, unless you can get it on a ramp then you can get at them from underneath

He reakons he has cleared the scuttle ones fella! :( He asked if its ever had a replacement windscreen :Confused: It is now just a small drip like a tap, needs more investigating! :rolleyes:

Anybody around the Glasgow area that knows of these leaks that could look at this for me???? :cool:

the reason I suspected scuttle drains is that the above post only mentions the air-con, "botangs hole" and the wheel arch ones, I would suggest checking with him on how he did them just to be sure, certainly still points to them I would suggest, post back what he says if you dont mind please, if its not them its going to be someone inside the car with a hose outside I'm afraid:(

cheers

I sent him all the links so he could read then copy! I think it's the one that needs a bit of bent pipe to clear as he's probably not followed the technique exactly! I have just read that "A4 AUDI" knows how to clear these and have done it before so I think I might need to pay them a visit! :rolleyes:

I just want someone to say "yip that's the problem and yes I can fix it now" :ROFL:

My old Mk3 Golf VR6 had a water leak and it bugged me so bad as I couldn't find where it was coming in, I really hope it's not the same with the A8! :tuttut:

Richie.. I'm only 5 minutes down the road, could pop up sometime and take a look for you.

Fella, that would be super! When I get the car back next week ill drop you a pm and you can let me know when suits? Thankyou! :D

PsYcHe and Richie, I visit good friends in Blantyre a few times a year, and have often played golf at East Kilbrise Golf Club, I'll be sure to watch out for you both on the road next time I'm up that way, which is possibly between Christmas and New Year.....+++

And by coincidence I had the problem with the air con drainage being blocked a few years ago and it was my mate from up there who discovered how bad it was when I threw it round a roundabout and soaked his shoes........:ROFL:

I've moved the meet discussion from here to a seperate thread as we were veering very far away from the original item

Thanks, good moderating skills. +++

Did you ever get to the bottom of this?

Yup, my mechanic cleared all drains, the ones under the arch were clogged solid and he removed all the ecu electric stuff under the windscreen and sealed a small hole that had a rubber grommit in it. He said the grommit was the problem it wasn't water tight. It looked like someone had tried to seal it brfore my ownership. He also removed all my interior and dried it out as he was concerned with some electric stuff under the floor staying damp. So it's been totally dry in the cab and no more steamy windows! I still check every now and then, its called paranioa! :ROFL:

Glad you got it sorted, so it was Botang's hole that was the source.
