    2017 Discovery Si6 HSE Corris Grey

    Heavy steering

    Before I go and blast the dealer about another software glitch ….

    My steering feels variably heavy and a bit lumpy.

    It feels ok when making a turn but returning the wheel seems heavy …..both directions.
    There is a marked contrast in movement from finger tip to arm ache.

    I also think the steering wheel is not perfectly horizontal ….leaning towards 11 o’clock on perfectly flat straight road. It’s only a fraction out but I am dam certain I would have noticed it before.

    My question is…can steering lose positional calibration like other components ( eg like seats) Could it be getting the wrong signals from wheel turning?

    The car hasn’t been driven anywhere since it had the seat calibration done until today. I mentioned on another thread that the technician said there had been glitches with the N877 security update , including “a steering issue”.

    Before I go and read the riot act over this being yet another problem due to the update, I just wondered if there could be another reason ? To be clear it hasn’t hit any potholes, tyres are good, alignment was done 1month ago……I’ve driven it sense then locally with no obvious behavioural problems. But I’ve just don’t 200miles and it drives smoothly. But steering feels unpredictable. A couple of times I made a sharp pull out to overtake and needed more effort to bring it back straight, ending up over correcting….a bit unnerving till I started getting the new feel.

    Thoughts?

    I had the same heavy steering fault. Turned out to be a rear wheel ABS sensor. Although I did have various warning lights illuminated on the dash - including ABS Fault message.

    No warnings showing.

    The car is perfectly drivable, just a bit “different”.

    In fact it’s reminiscent of when I towed with a D5 for the first time.
    It felt then like the steering had a slight delay in responding causing me to oversteer. With a large trailer on the back it felt unstable due to my jerky steering. But we’ve “got to know each others mannerisms” over the last 6 years. Lol


    Yesterday I went to overtake and it swung out further and faster than it normally does for my normal arm movement causing me to have to correct…then finding I had to use more force than expected to correct, than it did to move out.

    Call it coincidental but since the software mucking about, this feels like the cars decided to change how it steers …..which makes me wonder if the steering module needs calibration (if that’s at all possible)

    Think I will have to visit the dealer and face the inevitable argument. Life’s too short for all this!.

    Did you get anywhere with this? My steering feels a bit heavy and I’m not sure whether it’s actually a problem or that I’m driving the Defender day to day and the Discovery far less. It felt very heavy today.

    I did have the windscreen replaced on Monday and they recalibrated ADAS etc as part of that. A few days later I went to get something out of the car and got a battery low warning. This is something that’s happened before, after having an MOT somewhere other than the dealership. After that the battery went completely flat - the RAC chap said some third party diagnostic tools leave certain modules in a state where they don’t sleep. Anyhow, charged the battery overnight, cleared any errors (couple of random BCM errors about lights) and all seems fine.

    In terms of the steering, do you know whether it’s electric or hydraulic? If the latter I’m wondering whether it’s the drive belt slipping.

    Reading this thread, the first thing that sprung to mind was lane assist.

    Something mechanically wrong it could be,
    but the way you guys describe the symptoms, who knows!

    Speed sensitive steering! or lane assist,! now that would tie in with software / ads gremlins

    Could be. I might just disconnect the battery completely for a day to ensure every module has had a proper reboot.

    In my case, it could be that I've primarily been driving the Defender so perhaps my personal calibration as to what's 'normal' has been thrown off a bit. But today it did hit me that the steering felt heavy and it's the first time I've driven it since the windscreen was replaced. My wife drove it home from Autoglass and she's not that familiar with it so probably wouldn't have noticed.
