A power steering fluid leak on a Polo is worth finding out early on, because a small weep can quickly turn into a bigger problem with more costly repairs.
Where the Leak Usually Starts
Here are the 3 most common areas where power steering pump leaks occur, and what type of leak you can expect to find: 1. Shaft seal for the pump shaft, inside the pump casing. 2. Hose union for the high-pressure hose connected to the pump. 3. Reservoir inlet, where the reservoir tank for the power steering fluid connects to the power steering pump.
How a Small Leak Gets Worse
This means that running a system with low levels of power steering fluid will cause the pump to whistle, overheat, and wear its internal bearings very quickly. A weeping seal can very quickly develop into a seized pump, which can cost a lot to repair and often has to be replaced in its entirety.

What a Mechanic Will Do
When Replacement Is Unavoidable
When a power steering pump starts to wear, it will start to cause problems and these need to be addressed as soon as possible. Often, problems with a power steering pump start with a cracked power steering pump body, a worn / scored power steering pump shaft or signs of internal wear, which can often be noticed by means of a groan or grabbing when steering. A simple seal repair will not be sufficient as the pump will already be showing signs of mechanical wear.
This has to be spotted early on to prevent bigger problems!
