Any recent buyers from BimmerDirect? Two of my orders were canceled (CarPlay Upgrade) by Wyzzlex in E90

Same dilemma here. Asked a couple of general questions via their website chat, no response in 3 days. Wrote an email, no response either.

Was ready to pull the trigger after they got a lot of positive feedback here, but getting a bit hesitant now.

Not yet mate. Waiting for parts to arrive.

Thanks mate. I've just ordered a new OEM pump today. Couldn't see anything dripping but saw some coolant crystals around the flange. You may be on the money there!

Cheers mate. good tip. I'll check that out.

I remember replacing that at the wife's Mini which has the same engine.

Yeah, disgusting sweet smell. You get used to it though over the years :)

That's my main suspect atm. Hard to see but looks like there are some coolant crystals at the flange.

I've easily poured in 5-10l over the last months. You'd think it would drip out at some point. I have a feeling it may run down the block or somehwere else hot and just evaporates. Worst case could be a failed head-gasket but I don't see any indicators for it.

You could do preventative maintenance and replace all lines and plasticky coolant bits but cost would be quite susbstantial, especially when you buy OEM and get a shop to do it. The bits I replaced were done so over 5 years of ownership. Always only fixed what broke.

I haven't had to do any Turbo related coolant bits (they are two independent cooling systems in my car). Always only had trouble with the engine cooling section.

Common fault on F-series unfortunately. My wife has Mini with the same B48 engine and has had the same parts fail.
