Audi_King Posted February 10 Posted February 10 (edited) Hi, I get this noise when turning full lock. It is the easiest to hear when turning left but it also happens when turning to right but quieter. Is it normal or what it can be? Happens only above 12 km/h.

Steve Q Posted February 10 Posted February 10 Could it be an issue with the power steering pump I wonder?

The Verb Posted February 11 Posted February 11 On full lock it will need a bypass system and the humming noise may well be the bypass in operation. Our VW has an electric PS pump and it does make a noise on full lock.

And also I see you have an S3 from 2018 - does it have the same noise? Thanks for the info. Edited February 11 by Audi_King
The Verb Posted February 11 Posted February 11 Hi - We also have an 2019 A3. I've just checked both cars and no noise comes on full lock steering at slow speed. Apologies as it looks like the steering is an electro mechanical one, so no hydraulics with bypass involved. Some cars have an hydraulic electric pump which make the humming noise. I'll get back in my box.

The Verb Posted February 11 Posted February 11 Yes, I was slow in both cars and no noise. The VW is a polo but that is an electric hydraulic pump so is a different system to the S3/A3. I'm out in the S3 tomorrow so can check when its cold, but I've never noticed anything and I usually notice anything untoward.

Full left turn and make circles. Make sure you have at least 12 km/h or 8 mph. Also - what tires do u have in A3 and S3? Model and size. Edited February 11 by Audi_King
Sid2020 Posted February 11 Posted February 11 A whine at full lock that was not previously there could either be a drop in fluid level or steering pump nearing the end of it life but you should avoid holding a hydraulic steering system at full lock as it puts a lot of strain on the pump
