2018 BMW 2 Series in with a coolant loss issue 💧🔍
After inspection, we found the oil filter housing with integrated water cooler had failed and was leaking coolant. These are a known weak point and can cause some serious headaches if left unchecked.
To confirm the fault, we carried out a full pressure test on the cooling system, which quickly revealed the leak from the housing.
✅ Removed the faulty oil filter housing
✅ Cleaned all mating surfaces
✅ Installed a brand new housing with water cooler
✅ Refilled and pressure tested again to ensure everything is sealed and leak-free
All sorted and back on the road with no more coolant loss 🚗💨
If you’re noticing coolant loss or smells from your engine bay, don’t ignore it—get it checked before it turns into a bigger problem.
