Where are the drain holes under the ECUs

[ghemmings]

Just noticed a pool of water in the windscreen drainage channel. I have searched the forum and audipages, but can't find details on how/where to unblock the drain holes under that channel under the windscreen. I'm a bit worried as the water level looks quite high and close to the ECUs box seal. The gearbox seems a bit more lumpy than usual, which made me look there!! Hope its not a wet ECU or two!!

It deep under the black box so you wont be able to get to it from the top. You've got to get at it through the passenger wheel well; poke something, say a screw driver up the rubber tube thingy and it should start to pee the water off.

It's the last part of the procedure "Checking the cowl drains" and it's the last four pictures which show using compressed air with a copper tube. In the US, you can get 1/4" copper tube at the hardware store for refrigerator use for an ice machine line.

Thanks guys, problem solved. Easy job. It was a combination of a screwdriver and squeezing the rubber tube thing and all the water came out. I tricked a couple of pints of water into the channel and continuously squeezed the tubes to flush them out. I'm now going to open the ECU housing to check for water ingress!
