Hi Guys,

I've been using the site for several months, since buying a 2010 TDV8, and have found it a great source of information, so this is my first post, for your thoughts on some problems with the car, and the dealers response when it went in for attention under warranty.

The car had about 8 or 10 problems to be sorted out, some of which I'd already identified by searching this site, most of which are now resolved.

However, there are still three problems outstanding, which are driving me nuts, and the dealer seems unwilling, or unable, to rectify them, so any advice would be appreciated.

The first, and most serious, is the traction/anti-skid control.
At 15-20 mph on a dry road, the system will kick in when going round a roundabout, and will continually apply the brakes until I exit the roundabout and the steering wheel passes the 'straight ahead' position.
Having seasrched the site for information, I've read of some issues with the steering position sensor, which I thought may be the problem.
However, as I've fitted 22" wheels to the car, the dealer is saying that's where the problem lies.
(The only other comment they did make, was to point out that I've invalidated the warranty as far as any suspension issues are concerned!).
Having browsed the site, I see there are numerous other owners with 22" wheels, so I'd be interested to hear of anyone else with similar problems/solutions.
(Just for info, I've increased the tyre pressures to some of the values recomended on this site, by other owners with 22" rims, so I'm reasonably confident that the pressures are not the problem and the car is fitted with Toyo tyres, which should be of decent quality).

The second problem relates to the tyre pressure monitoring system.
When I start the car, the system understandably reports that tyre pressure monitoring isn't available, due to the non-standard wheels.
However, after driving the car for a few miles, it somehow decides that TPMS is available, and flashes up a message on the dash.
Subsequently, after a few more miles, it then decides that it isn't available, and another corresponding message appears, and this sequence repeats at varying intervals for most journeys.
The dealer claims that this is totally normal and is only to be expected with non-strandard wheels, but I'm convinced that there must be a problem, if the system thinks it can see non-existent pressure monitors?

The final problem is apparently the EGR valves.
When I stop the engine, there is a loud, high pitched squeaking sound, almost like pump running under the bonnet for about 5 seconds.
The dealer told me that it's the EGR valves going through a cleaning cycle and the squeaking sound is proof that they're working as intended.
Apparently, as they're working, they can't/won't do anything to them under warranty, despite the ridiculous noise that it creates.

I've been a Land Rover owner for 11 years, (2 x Disco's and now the RRS), and if I can't resolves these problems, this may well be the last LR I own, as my wife is so distracted by the various warning lights/messages/noises, that she won't even drive the car! (I guess some may see this as a benefit, but I like to be chauffered back from the pub occasionally!).

Thanks for reading all this - hopefully someone can offer some advice?

Cheers,
Rob

is it a Stratstones?

No, not Stratstones - haven't used them since I had the first Disco.

The EGR noise is probably audible from about 20 feet away, so fairly loud. (It turns a few heads if I pull up outside the pub and there are people in the beer garden!).

as for the non-standard tyres invalidating warranty - I enjoy a good difference of opinion customer/dealer as much as the next guy, but this is going to be quite a struggle me thinks. It's a bit of blanket rebuttal, but that doesn't mean it's not valid.

personally, I'd ask Bobby to supply the workings of the ABS/ESC and see if the wheel size (assuming correctly inflated, tracked etc) could even be a factor in the way the system works?

there was a guy who discovered a diesel leak was causing his system to activate constantly.. the diesel was leaking under the rear tyre and genuinely causing it to slip in corners ============

Thanks for the info.

I checked the rolling radius details quite carefully, to ensure that the 22" wheels/tyres were as close as possible to the original 20".

The car speedo compared to GPS speedo shows just 2mph difference, so probably comparable to original wheel readings? (The car is over-reading as you would expect for safety margin with speed limits).

There are no signs of leakage of any kind on the drive, so I think I'm safe to assume that it's not losing fuel.

On the Traction control etc. - you haven't got Hill Descent Control (HDC) selected have you? or perhaps there is an issue with the HDC thinking its on. This creates a very similar effect when not actually being used to descend a hill.

Also the ride height sensor can also do the same as it reports "too much roll" and tells the TC to slow the car down. 2016 RRS 4.4 TDV8 Autobiography Dynamic in Montalcino Red and Stealth Kit

Have you had them do a 4 wheel alignment check ?

There are so many adjustments in the suspension that it may be one wheel is out of alignment that is causing the problem.

I may be wrong but I'm sure that was one of the problems I had when mine was out of alignment.

I had a 4 wheel alignment check and adjustment when I first got the car, as the original tyres were showing some uneven wear, so there shouldn't be any problems with that now, (hopefully!).

First tpms, why not have it disabled electronically?

On the wheel issue, you won't win the 22invalidating warranty issue...its true...but could you put the 20" back on to see if that's the fault?

Also I would try the steering angle sensor first Mike

i have 22 s on my tdv8 with no issues with them apart from the tyre warning light on dash, tyre pressures are set at 35psi and my egr valves dont make any noise, does that mean mine are faulty lol sorry carnt help with traction fault

That would be a good idea indeed, however quite why the dealer would blame the 22" if they're the same rolling radius I am not sure. Other than they are finding it difficult enough to diagnose and fix issues with standard cars, so any excuse to walk away from a problem is a good excuse. Not good customer service imo.

Whenever the car has had a 4 wheel alignment, the steering angle sensor should be reset. Sounds like this could be causing your issue.

The EGR's are noticeable, but should not be excessively loud when doing their self test. Keep pressure on the supplying dealer, and get them to compare it to a known good car. If the above gets you nowhere, escalate the case to LR customer care (if you have an LR assured warranty)
