Can the intake pipe be removed when a BMW is wading through water?

BMW wading can remove the intake pipe. Water ingress does not affect normal driving: If the engine has a significant amount of water ingress but does not affect normal driving, and only produces louder noises, it may be due to a small amount of water in the oil or gasoline. In this case, the oil needs to be replaced and the related engine components cleaned. If there is a large amount of water ingress and the engine has taken in water (not just a mixture of water), but the car has not been started and the engine has not been damaged, the water must be completely drained, the interior cleaned, and then reassembled with new oil replaced. However, the electrical system may not be safe. Water ingress affects normal driving: In the worst-case scenario, if the engine has taken in a large amount of water and cannot operate after starting, it means the engine's cylinders, connecting rods, pistons, etc., may have been deformed. At this point, the engine can be considered scrapped, and only a new engine replacement or complete vehicle scrapping is possible.
I've been driving for over thirty years and often wade through water during the rainy season. I've seen many people wanting to remove the intake pipe to prevent water ingress, which is a huge mistake. The intake pipe isn't just for air intake; it also protects the engine from dust and foreign objects. Removing it makes it easier for dust to enter and clog during water crossings, actually increasing the risk of water ingress and leading to costly repairs. When wading through water, stay calm. BMW's body design has a higher ground clearance, but water depth shouldn't exceed half the wheel hub. Maintain a low speed and steady throttle, and avoid sudden braking. After wading, check the air filter and undercarriage, and seek professional help if necessary. Safe driving is the most cost-effective approach.
As an enthusiast who regularly studies cars, I emphasize that removing the intake pipe for water fording is extremely unsafe. BMW engines are precision-engineered, and removing the pipe can cause the engine to ingest dust and water, directly damaging components. When fording water, always test the depth—it shouldn't exceed the door sill—and drive through slowly at a steady speed. Never force your way through deep water; this eliminates the need to remove the pipe and avoids bigger troubles. After fording, perform a simple self-check of the intake system. If any abnormalities are found, get it repaired immediately to avoid higher costs later.
Removing the intake pipe for water fording? Better not take the risk! When I encounter waterlogged roads, I always play it safe. BMW's intake pipes have a filtration function; removing them makes it easier for dust to enter and clog the engine. The key to water fording is measuring the water depth—it's best to detour if it's too deep. After fording, check the tires and chassis. Proper car maintenance ensures longevity.
