Heavy steering and failing stop start; connected?

The power steering on my D4 is heavy and inconsistent other than the first inch or so of travel either way. Fluid level is ok but the stop start is now also only operating intermittently. Anyone know if these are likely connected or is it just a coincidence? Thanks.

Stop start problem could be caused by a failing battery

Thanks, Yep I thought that and will replace it (main or both?). Could the steering by a symptom of a failing battery or is it likely there is something wrong with the rack/pump?

The main one but it needs to be replaced with the correct type AGM stop start battery.
The steering fault could be linked.

I would also check that the stereo amplifier is switching off there is a common fault with them staying active and draining the batteries, which will shorten the battery life. It will show up as a fault code if you have a reader.

Connected a reader and no codes. I do often sit waiting for kids with the music on which will not be helping the battery and at over five years old is probably worth a change. Anyone got a link for a good battery deal? Happy to fit myself.

Lower steering universal joint needs lubrication or replacing.
If the SS is failing without the eco light showing it is the main battery.
If failing with light on it is small aux battery.
And yes it is all related I’m afraid, it’s called poor maintenance Whistle Laughing
 It can when others can't,
It will when others won't,
It goes where others don't.

If you’ve got a charger it would be worth charging the main battery.
A CTEK will advise if the battery is so poor it can’t be charged.
Worth a try then you can see if steering issue goes away.

Good point. Have a CTEK and connected up the main battery and it took overnight to charge so must have had too many short runs and use of the radio when sat waiting for kids. Then connected it to the small battery and it showed up as fully charged.

Stop start now working fine and steering is not as heavy. Mind I have been driving my wife’s Golf a lot and that has Uber light steering so no questioning what is happening! Still think the suggestion of getting the garage to look at the knuckle joint makes sense though.

That's good.
Can I suggest if you're continuing to do short runs that you top the main battery up with your CTEK once every couple of weeks?
I've learned from this forum that a battery that gets regular and thorough charging will last longer. In addition your stop/start will keep working.

Agree, thanks. Will also report back when my local garage gets my car on the ramp.
