Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. It is common for the power steering pump to start to fail on this vehicle and make noise. It can also occur if the fluid is just low. If the fluid is full, but has never been changed then you may want to start there as old fluid can cause this. If the issue persists then it will need to be replaced. Please let me know if you need further help.
