Hi,

The other day the DSC warning light started flashing while on the motorway (about 60mph) this was accomanied with a message saying special traction functions unavailable. No other warnings.
Next morning fault had cleared, drove about 2 miles no errors. Next journy warning light came on after about 3 miles.
When the light is not flashing everything works as it should.
Battery is less than 12 months old and it has the extra earth strap. So could it be something as simple as a sensor just intermittantly dropping out of spec?
Has anyone else had this?
Guess i need a code reader can anyone recommend one that does'nt cost the earth?

More info would help - mileage and service history.

Could be a haldex issue.
When was the haldex unit last serviced (filter and oil change + pump screen filter cleaned). Is the haldex electrical connection OK ? Jules

I initially had a cheap supermarket OBD2 Vehicle Code Reader, but the codes were a bit generic and vague.

I now have an Autel MaxiAP AP200 and working with a smartphone allows quite detailed analysis.

When I had similar Traction Control issues several years ago, they came and went for 2 - 3 weeks but then disappeared before I could get them checked by garage. No re-occurrence of the fault has been seen, and my car is serviced in accordance with LR instructions by LR Dealer. (that is the transmission is ignored) FL2 XS SD4 Auto 2010 2012-2017 (21k - 91k miles) (MY2011)
FL2 Metropolis SD4 Auto 2014 2017- (16k - 76k+ miles) (MY2015)

Car has done 166,000 miles Haldex was last serviced 2 years 25,000 miles ago.

It needs a diagnostic read to determine what is causing the issue. DSC will shut down if several items fail. It'll normally be Haldex or brake related, but a diagnostic is the only way to tell for sure. 2009 Rimini Red SE TD4. Soon to be sold.

I had the same thing, light flashing and transmission failure flashed up then went out along with the DSC, slowed down, heard nothing, continued to drive smoothly, sped back up, nothing, happened once again a few days later again no problems, then the following week went to start the car and a click of the starter solenoid and nothing, charged the battery all OK, following morning same again, bought a new battery and never saw any warnings again.
Just because your battery is only 12 months old it doesn't mean it is good, batteries can fail at any time, all batteries are the same, whether the warranty is one year or 5 years, the extra cost is just the warranty charge.
So unless the same warning continually re-occurs it's probably OK but if other warnings randomly flash change the battery. my PC is slightly to the right of Genghis
