Okay I mentioned this in my introduction post but the problem is now recurring with some frequency; however, it is still intermittent. Whenever you turn off the ignition the system resets and the problem disappears for an indeterminate period - sometimes it is recurring within a mile or two other times not for several days and many miles. Snapped a recent photo of the error message which I will post here "2 Wheel Drive Only - Traction Reduced". It first occurred at around 16k miles.

There is not consistent trigger, sometimes it is low speed climbing an overpass, others are turning a corner and yet others are simply straight line driving. About the only consistent element seems to be some degree of acceleration but there is not any one rate of acceleration that triggers the error message.

I have my 20,000 mile service scheduled in next month and I think I can wait until then unless the problem becomes permanent. I would appreciate any insight anyone else has to this problem.

You most likely have more miles than any other Disco owner to date. I bet as others catch up, some will get this alert. Please let us know what you find out.

What are the Evoque owners saying about it?

Interesting - I noticed you drive in Sport mode - does the issue happen more or less in Sport mode instead of regular Drive mode ??

Also, since you mention while turning or uphill drives, the traction control message seems to appear more when either the torque vectoring during turns and/or traction control during uphill is more active.

Can you try to see if snow, ice, rain or other slippery conditions create the error message ???

You need an OBD II scanner. Scan for codes. I haven't tried on our our Disco yet, but it's a lifesaver with my Audi, which, as any properly functioning VAG vehicle always has a check-engine-light on. I'll look into it myself, but I have a cheap $20 scanner tha plugs in and talks to an app on my iphone.

What about hitting your "InControl" roadside maintenance button? Seems this is something they'd be able to help answer.

Good info!

Does the Roadside button transmit the error / fault messages to their center ???

I would assume it's capable of doing so? Still, I'd ask them what the warning means. Last thing you want in a Land Rover is not being able to rove.

Running with Reduced Traction

I haven't taken the car to the dealer yet but have discussed it with my service tech. Apparently it is okay to drive the car in two-wheel mode. If there is a more serious problem the car will shut itself down. Unfortunately the car drives like sh*% in two-wheel mode.

I have also researched this extensively on the LR forums. The bad news is that this has been happening since 2006 on pretty much all models, RR, Freelander, LR2,3 &4 and Evoque. There seem to be various causes: low battery, software glitches, bad rear-differentials, even some complete transmission replacements. There doesn't seem to be a universal solution and often requires multiple trips to the dealer. You'd think they'd have a fix for this by now...

It happens in both Sport and Drive modes and is particularly annoying when it kicks in on slippery surfaces (which fortunately has only occurred once). Again there is no common denominator other than acceleration which can be a lot or a little. It rarely happens soon after a cold start but again hot or cold ambient conditions and length of drive time all vary. Sometimes you can stop/start and it goes away the rest of the day or it may come back within a mile or two.

My car did not come with In Control - not sure why, maybe I didn't elect that option but it may not have been available at the time of my order - December 2014.

I'll post back whatever else I learn but won't be going to the dealer until 11-Jan unless the problem becomes more frequent. It has happened on each of my last several drives so I may not be able to wait that long. It sucks driving in tw0-wheel drive mode - if I had wanted a two-wheel drive car I would've bought one.

Ranchos - what would the OBD II scanner tell me that I could use to get this fixed?

:crying:

The OBD scanner which will tell you of codes is inexpensive.

I bought one for $20 on eBay, plugs into the OBD port and it talks to my phone's app using Bluetooth.

Here is a YouTube video on how to use this works:

This is the wifi enabled OBD I bought:

Though I see it's discontinued... it was like $25

if you have an iPhone you need a wifi version and not a bluetooth version. Apple's bluetooth protocols are, unsurprisingly, compromised

Thanks Ranchos and 4sallypat - I'll look into the scanner ASAP.

Now at 19.3k miles and "Reduced Traction" problem is pretty constant (feeling snake-bit again). Fault still clears on stop/start but returns after a few miles or even less on just about every trip now. Usually accelerating out of a turn or corner is when I get the dreaded "ding" from the dashboard warning light.

Spoke with the Manager of Service Department at the dealership earlier today. He has seen this problem before on other models and feels fairly certain that either a software update and/or replacement pump will do the trick. Apparently the pumps can cause pressure fluctuations which the all-wheel drive reads as a fault - nothing really wrong with the pump just not quite right either. He's going to try and work me in before 11-Jan. Will keep you informed on progress.

We also discussed the gas gauge re-calibration and we are going to go with that too.

Hi LRDSnTexas did you get this problem fixed? What was the cause?

This started to happen to mine after I started driving in D (usually in S)

 

[LRDSnTexas]

Vizfiz: Indeed I did get the two-wheel drive problem fixed - see my report here: http://www.discoverysport.net/forum/38329-post12.html Short answer: replaced rear differential, 25 days in the shop. Covered under warranty.
