vagcom is saying 'not only is the motor short' but there is no output from the fuse to power it. Hit the stalk wash and heard/saw the fuse blow. Photographed the fusebox then removed and tested every fuse in the cockpit box. Next morning I thought no power, therefore there must be a fuse somewhere, but no decent fuse table I could trust. Cover now off the relay mean't I could hold the contacts down and see if the pump worked. Ended up pulling off the relay cover! Wanted to test the pump motor without dismantling the car. I tried extracting it with a tool I made.
I made a good guess that Relay 404 was for the washer. That thing handles just about very function you select inside the cabin.
With very little info I worked out in the driver foot well there is a unit called the Onboard Supply Control Unit J519 with a relay panel bolted to it. Now such simple things should not be too difficult and a washer pump must be one of the cheapest parts on an EOS, but read on.įirst I got my head around their system. Asked wifey and she said Oh, it stopped working last week (30K miles). I tried the washer on the stalk and it was no go. I ran a vagcom scan just by chance and it came up with:Ġ0156 - Control Circuit for Windshield Washer PumpĠ09 - Open or Short to Ground - Intermittent The most common complaint is they took out the washer pump, hooked it up to a battery, it ran and then they were clueless! Most are misleading because the posters do not understand how the electronics are designed. There are several posts about this for VW cars.
