Tight Tolerance Mode

Before I get a 4 wheel alignment done, I would like to get my discovery into tight mode, is there something I can buy to allow me to do this my self? If it needs to be done by a dealer would I be expected to pay, suppose it would mean trip to dealer to apply tight mode then after wheel alignment back to dealer to take tight mode off. All the wheel aligners I've Spoke to have never heard of tight mode but say they have done lots of Landrovers sucssefully. I must admit I had the Discovery 3 done without tight mode and that was great.

Most of the Landrover specific tools will be able to do it.

IID tool and Nanocom probably offer the best price/functionality ratio

Would be expensive just for tight tolerence mode but you can do so much with them, change settings,read faults, calibrate etc.

You dont need to put it in tight tolerance mode as such now as the hunter alignment tools are so sensitive it does not need it.

When LR came out with the geometry for the suspension the equipment was not as good as it is now.

It will be fine either way you choose.

Surely the issue isn't with the sensitivity of the alignment equipment?

In normal tolerance mode the suspension won't change unless there is 10mm difference so in theory you could have one side at +9mm and the other at -9mm so an 18mm difference the suspension not adjust.

In that senario if the vehicle was adjusted with senspension like that then when it was level both wheels would have different camber settings. Marginal yes and possibly within spec.

All this relies on the vehicle being calibrated corectly in the first place.

Not required, if your set up is well out of alignment (mine was recently after new steering rack) you will notice the improvement in driving straight away. Just make sure they have decent Hunter gear.

I still prefer tight tolerance mode and loaded roughly in accordance with the workshop manual.

Thumbs Up - which is mainly that it should have a full tank of fuel or equivalent weight added - I wonder how many are aligned "as is" - probably does not make a huge difference, but worth doing properly

Thanks for all your input guys. Just one last thing how far can you drive a Discovery while it is in TIGHT TOLERENCE, if my service mechanic puts it in TTM coul I drive a round trip of 30 miles to the wheel aligners?

Not sure if it's the same on a D4 as a D3, (I would think so Confused )

I recently left my D3 in TTM for a short while after messing with my Nanocom Evo and apart from keeping a suspension error light on it also seems to tighten up the ride significantly, the local roads here are a mess of potholes and speed humps and it was almost like riding on the bump stops.

I guess that's not really surprising since in TTM, the EAS system is working overtime to try to keep the car level.

So I guess the answer to your question probably depends on how good the roads are where you're going.

Thanks for that Clive, just good roads between Milton Keynes and Bedford, so if it comes back from its service in Tight Mode,sounds like I should be OK.

In TTM does the engine need to be left running while the alignment is being done? My garage doesn’t want to leave an engine running for that long in a shed, exhaust fumes would be way too much. Thanks

I would guess it depends on how much adjustment the air suspension has to do and if the reservoir can hold enough with being topped up. Cant they leave the shed doors open? most tyre places have at least one big door and ive never seen them shut.
