Spare Wheel Protector

Hi All,

Now this may be a very dumb question but my 2014 D4 is telling me my spare tyre needs air... looking underneath I can see the spare wheel etc so all good..... the dumb part of this question is that ot has a spare wheel plastic protector on it (LR078960) ...do I take that off first? If so, how does it come off? I only need to put air in the tyre but do I have to remove the whole spare wheel? as in lower it from inside the boot?...

Thanks in anticipation.... MY2014 Discovery 4 XS - Loire Blue

Hello,

This will be in the manual but yes, you'll need to lower the whole wheel to access the valve and maybe remove the plastic wheel protector to do so but maybe you can wriggle it loose and just access the valve?

Be careful to keep the lowering cable under tension or it has a nasty habit of 'birdnesting' inside the bodywork and then you'll have to replace the whole thing.

Longer term, you can get an extension tube for the spare wheel valve so you can keep it inflated without lowering it. have a read here for further info:

Just my pennies worth.

2016 D4 SDV6

SWMBO has been running fine for eight years with no spare wheel pressure warnings. Recently she has been getting a ‘spare needs air’ message . The only thing that has changed is that her annual mileage has fallen off a cliff – 21,000 miles a year to 7,000 miles. Toooo many very low miles trips.

I know that this new message is due to a reduced average battery voltage change flagging up spurious messages - nothing to do with the air pressure of the spare wheel. How am so I sure? Because the first thing I did when I got the car is to remove the factory spare and replace it with a tatty D3 19” spare. For all these years the car has not cared that the spare has no TPMS….

Give the battery a good charge and see if the message goes away (I am also getting ‘water in fuel’ messages – a long journey and these both go away)
Could also be a sign that you need a new battery. Lots on this forum about weak batteries causing spurious messages.
