2022 430i.
I need to pressure wash/ clean my engine and engine bay. I will not use high pressure.
What precautions do I need to take to prevent damage to electrical and other systems? Any advice on this process would be greatly appreciated.

All I do is make sure I don't use high pressure near the engine. I hold the wand a bit far away. Spray with water. Then use a brush with soap to get most of the exposed parts (obviously remove the engine cover before doing this). And then again, wash away the soap with the pressure water wand held a bit far away as usual. I've washed my bay around 5 times so far on the 330i (and many more times in my other cars) and zero issues.
