    Good diagnosis and repair, people don't realise just how little moisture can create such trouble 😢

    On mk2 caddy's we had ecu problems due to water ingress on the circuit board. This was often sorted by cleaning the affected part of the circuit board with rubbing alcohol. Worth a try👍🏻

    For such an expensive piece of kit located at the bottom of the vehicle it's somehow unbelievable that it's not properly insulated to the elements.... Come on Audi get your act together

    Do you know if the new AdBlue ECU has been improved to be better protected against corrosion? Atleast it has a new parts number index. My local mechanic said he hasn't seen newer ECUs with this issue, but maybe it could be due to them being newer and they'll have to same problem later...
