GLK air suspension malfunction

Your description sounds familiar I also drive a GLK with air suspension and had similar symptoms Did you notice any hissing sounds near the wheels That could be an air leak around the bellows valve or air spring Have you checked the air lines for damage The system can't maintain pressure when the bellows valve is defective You mentioned error messages Do they point to a specific corner or a general system failure

I heard a faint hissing from the left rear wheel The error messages initially indicated a general malfunction but after repeated scans a more specific code emerged pinpointing a potential issue with the height sensor on the same left rear wheel Could this sensor malfunction be a consequence of the air leak or are these two separate problems

The height sensor issue could be a consequence of the air leak If the air spring is constantly deflating due to a faulty bellows valve the height sensor will register incorrect readings Given the hissing sound and specific error code it's probable the bellows valve is the primary culprit I recommend taking your vehicle to a qualified mechanic for inspection They can perform a pressure test to confirm the leak's location and assess the bellows valve If defective replacement is likely best The air suspension system is complex and requires specialized tools and knowledge

Based on your advice I brought my vehicle to a trusted workshop They confirmed the defective bellows valve The repair cost was 590€ After replacement the air suspension system is functioning flawlessly Your assistance was instrumental in achieving a swift and satisfactory resolution
