BMW 525i Power Steering Reservoir
Troubleshooting for BMW 525i Power Steering Reservoir Problems
The BMW 525i power steering reservoir holds the power steering fluid, which helps the system function in helping you steer your vehicle better. Without this component, the fluid might leak, causing the system to overheat and the steering gear to fail. Because you wouldn't want these to happen to you while you are driving, it is highly important that you diagnose your power steering reservoir.
When diagnosing the power steering system, the first thing to do is to check the power steering reservoir. Wipe its cover before opening the component to prevent dirt from getting inside. Your car's power steering pump should have a small dipstick built into the reservoir cap. This will show you the fluid level in the reservoir. If there is no specific filling levels indicated on the pump or if the dipstick isn't legible anymore, check your owner's manual for instructions.
If you find that the fluid level is very low, examine the power steering system for leaks. Check all connections, hoses, and couplers for evidence of fluid leaks. Because dirt may be attracted to the oil, it may be necessary to pressure wash the power steering pump and box before you look for fresh oil leaks.
Diagnosing hard power steering
When the power steering is hard to work and your car is cold, then several factors may be in play, ranging from mild to severe issues. When troubleshooting this, make sure that you try the least expensive method first before you move on to the costly ones.
The first thing you can do by yourself is to let your car warm up for a couple of minutes. The power steering fluid becomes thicker in very cold temperatures, causing it to not flow as well as it normally would.
If you haven't done so, check the power steering fluid level and make sure it is completely up to the full line. If it's not, then add more fluid. Especially if you are in a cold area, it is very important to maintain proper fluid levels.
If these don't work, then take your car to a mechanic and have it checked. An electrical mechanism might have gone wrong.
Other troubleshooting tips
Before you begin any power steering reservoir troubleshooting, make sure that any steering or handling problems are not caused by a mechanical component in the front suspension or steering mechanism. Troubleshoot these parts first before moving on to the reservoir itself.
