Welcome Ade. Plenty of info available on this forum and the other. Especially on the oil dilution issues on the 3 litre. I'm on 2 services a year and I only do about 8k a year but maybe that's the problem.

Because you love the Land Rover marque. That's why you are still lurking round the forum. Go on admit it.

As above unlikely this would be monitored. Also can't see how a repaired tyre could enter the supply chain at the factory. Seems a bit of a mystery. Keep us posted.

Welcome Andy. I don't have that system myself but their are quite a number of threads covering this subject on both this forum and the more popular site. hope that's of help.

No not normal. Definitely a fault if all you are doing is sitting on the foot brake left in drive. Mine shuts down sometimes if I shift to park and leave it.

Put the canoe on sideways.

Sorry couldn't resist.
No sensible suggestions I'm afraid. It's construction doesn't lend itself to easy fix short of having roof bars that stand a foot off the roof.

The overall size will be the same unless talking about width.

Certainly looks like one of the few that's being used for what it's designed for. I myself have occasionally had to negotiate the odd tricky supermarket car park.

Yes I believe that's correct. I once got the alarm for low pressure of the spare.

The answer to above is No. Not the 2litre configuration fitted in the Discovery 5. However the 2l disco sport is another issue.
