Power steering issue

[Andy2020]

Hi peeps here goes I recently purchased an RS4 B7 but whilst driving and coming to a junction or roundabout the steering would go really tight making it impossible to turn but then just come back to normal then found out it had wrong fluid init so I put the correct fluid init and took it out for drive got a mile down the road then same again but this time it didn’t come back it’s just proper stiff as if the pump isn’t working left it on drive for few days started up today and just can’t turn the wheel could this be the power steering pump any advice would be appreciated 👍🙏🙏🙏🙏🙏

The wrong fluid may well have degraded and swollen the rubber seals in the pump and the ram. If so they will have to be replaced.

I’ve got a pump replacement just hope that works as I’m hoping it doesn’t need steering rack too massive cost
