It ended up being the water pump seal. They replaced the water pump and thermostat free of charge.

Get a pierburg if you can for the water pump. They’re more OEM than Mehle is for water pumps even though both are OE manufacturers.

Pros: more OEM

I paid similar for a BMW TBF, however, another garage told me that the garage I went to was known for charging high prices. I always shop around when the price is in the hundreds so I'm confident I wasn't ripped off.

I had my 2008 BMW 135i E88 for going on 14 years, it's about to hit 70k miles and looks like new. I've done a couple bolt-ones (IC, charge pipe, Cobb tune). It's been a great car and a blast to drive. I did replace the water pump this past summer otherwise normal maintenance.

Pros: great car, blast drive

Cons: water pump replacement

Vehicle: BMW

Mileage: 112654 km

Pros: enjoyed the car

Cons: expensive when breaks

I had an 2001 740iL that I traded an old truck for. The electronics are kind of a nightmare, the water pump has a plastic impeller that likes to randomly explode and shoot plastic all through the cooling system. You can buy one with a metal impeller that solves this.

Pros: metal impeller solves issue

Cons: plastic impeller explodes

Vehicle: BMW

The cooling system is the major weak point (ask me how I know) - water pump failed before 70k (changed under warranty)

Cons: failed before 70k

Mileage: 70000 km
