Yes, this is the correct product for you 2019 BWM 540i. **Q: Can you mix this with the bmw brand coolant? thats what is in my coolant system currently. this product seems to be basically the same thing as that.** A: Yes, you can use PEAK OET Extended Life Blue for European Vehicles but I would recommend performing a complete flush and fill first. **Q: i bought this for my 2009 ml350 4matic thinking it was correct color. mine currently is yellow and the bottle is blue coolant, can i mix these?** A: Do not mix coolants of different color. This can cause corrosion and damage the engine. It sounds as if your coolant was incorrectly filled somewhere with orange which is used in GM vehicles. The German cars all call for the blue coolant. This would include your Mercedes. You will need to drain your coolant or have it flushed in order to add the proper blue coolant. **Q: Can you add this in with other coolant or do you need to flush the system first? I've been using the bmw branded coolant.** A: If you want you can no need to flush it. since you’ve been using BMW coolant, it should be the same blue color as well. ## Customer Reviews ### ⭐⭐⭐⭐⭐ OE *by R***T on March 1, 2026* OE and affordable. ### ⭐⭐⭐⭐⭐ Excellent coolant!! *by H***O on October 9, 2025* I bought the concentrate to top off my reservoir in my 2007 Mercedes.
