Hey Greg! thank you, Im not sure atm, if it was , it could be an old ECU?

All I know is that the ECU is un7repairable and requires replacing... I cannot trace anything back to the alternator or that shop for costs of damage caused. I need more proof for that.
My guys in the workshop atm have removed the odl scorpion alarm too and will fit the new ecu once it gets made and sent off to them .. then it'll be a case of new alarm / fitting , further work done on car and get car on road - then cambelt change and renewing of parts to 7get her ready for a april Nurburgring trip.

Glad to hear you are getting sorted out. Was the damaged ECU caused by the alternator?

[Chris5044]

Hey guys!! an update on all of this! My ECU is gone and unrepairable! so I am getting a new ECU from Emerald, The electrics are being sorted by a specialist also, so hopefully this will get the car running again. Then its tlc time again!

Hey thank you! yes this is the plastic vent I was talking about the first picture.
And yes it is collecting here the water, so it could come from here or from somewhere else as the footwell is the lowest part. since I checked last theres less water,, its more condensation now and not a small puddle.

The car has now been transported to an electrical specialist. Fingers crossed x

Got an error and after refresh it´s all here, sorry for the redundancy!

[psiconauta911]

Yes that is the plastic vent for the rear seats but is the water coming from the vent or is clecting near it?

[psiconauta911]

I think you mean nº 23 in this picture: https://audi.7zap.com/en/rdw/audi+80.../8/819-819030/

In my post I was refering to nº31 in this one: https://audi.7zap.com/en/rdw/audi+80.../8/820-820010/

[psiconauta911]

Hi,

If the vent you mean is a thin rectangular section plastic channel kike the nº31 in the first picture than it´s the ventilation channel for the feet in the rear seats.

The drain I talked about is the nº31 in the 2nd picture and is the drain from de evaporator housing o the A/C and i located where the passenger footwell(LHD) meeets the center console in the upper left corner, in my case the water collected in the base of the footwell but it was a lot!

Have you tried tasting the humidity your getting to exclude refrigerant loss through the heater matrix? Is your coolant level dropping even a tiny bit?


I get an error when I try to upload a png file so I´ll leave you 2 links with the images:

Hey psiconauta911, would this drain be a plastic like vent coming from the centre part of the dash? ie from where the 3 sensor gauges and in front of the gear stick?
In the drivers side footwell (RHD car) there is a plastic kind of vent that comes from like the centre console area and then feeds to the drivers footwell as a flatter plastic vent. around that was the wetness, but on the side nearest the drivers door.

Could water be getting in from this vent? and what is this vent? is it ventilation for the back seats? -- is there a leak elsewhere?

[psiconauta911]

The drain near the ECU is for the A/C system (at least in my LHD ABY Avant) and it ends under the car in a soft semi closed rubber tube (possibly to prevent any strange visitors too crawl up into the car like ants) and sometimes with dirt it gets obstructed and doesn´t drain the humidity condensed by the A/C, you have to get a rubber pipe of the same size and disconnect the drain tube under the glovebox (In LHD cars), and then blow as hard as you can it will sound like an elephant!I

And how do I know this? A few years back I went on vacation and did a 200mile trip with the A/C on, near the end of the journey I had to go up a mountain with a lot of curves and had smoke coming into the car from the central vents, kept calm as it didn´t smell because was only water vapour leaking from the drip tray on to somewhere that vapoured it, in the end of the journey I had 1/2 an inch of water colected in the passenger footwell, dried it up easely as it was summer, but it could have dripped into the ECU as it sits out of place in the front of said footwell and finished my summer vacation before it begun, so now every year I dismount the drain pipe from the tray and open it up by blowing into it preventing it from clooging again!

Good news
I noticed this morning my gasket bodge had slipped so I redid it and took a couple of pics.

wow!! dude! Thank you so much!! The pictures say all! I couldnt quite work it out in my head clearly! Thank you so much for your input and care. Goodluck with your leak!

Hey thank you again, upon inspection I have found less water ingress, so my sealing mission may have been successful.. I shall continue to observe and go over the other points made.

This is where you will see the water with the roof trim/ A pillar leak.
