Apparently it has fixed the issue according to the mechanic. So looks like I have a spare pump lol I still need to scan the codes with DIS though, because the indy won't have this software, but he is positive it was the cap.

The reason why I still haven't picked up the car is because I had my appendix removed 2 days ago lol Worst possible timing ahahah. So I will update this thread when I pick up the car and check the codes out.

It was interesting that their was so much coolant in the engine bay, I assumed if the pump had died then there shouldn't be any coolant, because what else could push the coolant out.

Normally wouldn't really be bothers by it and would change it myself, but I need the car fast so I took it to my local indy and I'm scared to even guess the price (I'm in Australia). I'm bracing myself for anything between $1000-$2000.

As far as I'm concerned the pump has lasted long enough, car is now 7 years old. 7 years is a very long time for anything electric. Just a bit disappointed I can't wait for the part from europe and do the change myself, would only cost me $500 damn you busy life :P

I would recommend to any other e90 owners to just change the pump as part of maintenance at 120,000 Kilometers/75,000 miles at the latest.
Hit me up, we ship all over the world !!!

It's not the expansion tank cap, on the way home from the mechanic it overheated. Man mechanics suck these days, this is why I do everything my self. My biggest mistake was taking it to him in the first place.

Charged me $120 for get this. 1 expansion tank cap, half an hour labour to remove the lower panel, pressure test the system and top up with distilled water. What a disgrace.

Scanned for codes with DIS. It's definitely the pump.

Have changed the pump on the weekend, didn't change the thermostat as I changed it about 7000 miles ago as it failed open.

My tips for doing this work.

1. Take your time, it's not too complex but it's not too easy either.
2. Take the radiator fan out.
3. Take the 4 bolts of and let the sway bar swing.
4. Any hose that is in the way remove it. They are easy to take of as the clips are simple pop in out kind of stuff.

The hoses on the pump and thermostat can be a bit of a pain though.

This will give you a lot more space to work in there.
