It has oil, think I may have some corroded electrical components/box?

Any help or suggestions are greatly appreciated.

Cheers, same to be honest.

Yeah all sorted now mate the box for the electronics under the bonnet had cracked (most likely when it or the ECU or the bonnet or the windscreen or something else was replaced), seems quite a common thing to go wrong, the place I took it said the had the same on an RS4 the week before (let's water in over time straight from the scuttle pannel if it's cracked).

If anyone else suffers the same this is a great guide: https://www.audi-sport.net/xf/threa...ngine-light-flashing-cause-fix-inside.143060/

I also had to replace some solenoids in the box that had corroded which is what killed it, I also previously unclogged the plenium drain plugs under the battery (which was unfortunately unrelated but a good thing to do to stop rain build up especially at the age our cars are now).

Treated my car to a few more go faster bits today so it best be ****** reliable now haha :icon thumright:

Glad you are sorted..... my tdi wont start at all.... just read the link you provided & all i get when i turn the key is an amber triangle with circle light. I fitted a new oem brake switch before all my problems started. Could this be a likely cause????

Well, glad you got it all sorted.

Thanks for the update Re: what to do if it happens to any of us. Quite easily done especially bad weather.

Haha, need to see more of your car. Some vids perhaps. :tongueclosed:
