It’s 2025 this is a 2008 LR two and all the years that this problem has existed. Has anyone narrowed it down to the most likely culprit
I’m the original owner in the early years 2010 or 11 it used to come on and go out giving no indication of anything being wrong. It disappeared for years and yesterday popped up again so I’m told anywhere from transmission fluid to Haldex fluid to Halifax filters or pump to wheel sensors ABS any fresh input on this problem thanks guys

 

Battery passes a load test?

 

Intermittent would suspect wheel sensor/connector or tone ring.

 

yes the is good I use a iCarsoft tool the battery is under a year old AGM Napa battery putting out 13.7 v running under load

 

Possibly but this problem started in the early years when it was only two or three years old I guess a ring could be bad but it disappeared for many years and now it’s popping up again could be a sensor, but I’m not getting any ABS faults it’s out right now it’s disappears. It doesn’t throw a check engine light and then it give me a notice again reduced traction the last time it happenedI had just pulled into a parking space put the car in park and it popped up not even moving so without spending a ton of money and running back-and-forth to a shop I’m trying to figure it out myself. Thanks for your input.
The differential was replaced at 40,000 miles. I’m sitting at 91,000 miles now I serviced the health deck unit twice myself new screens new fluid out deck fluid. I did not service the whole deck pump. It could have some sludge in it. I just recently serviced the rear differential I am planning on servicing the transmission. I decided to do a single flush and fill to start replacing about half of the fluid so many different viewpoints on this transmission shops wanna pull the cover and filter and replace all the fluid if they can get it all out other shops wanna do a single drain and fill other shops say to do three drains and flush and fill I decided on one it’ll take about 4 L out and refill half is better than none. No issues with the trainee curious to see what the fluid looks like. I’m gonna be replacing all three plugs the two drain plugs on the bottom and the fill plug on the top
saying all that for this car, the reduced traction is a mystery so far

 

Have you checked your tire pressures recently or changed out a wheel?
As a matter of interest the 13.7v output is from your alternator not the battery. Check the battery with the car not running and headlights or other large power draw on.

 

I brought all my tire pressures up to 35 lbs when summer ended in Oct and I’ll CK the battery as you described in AM thankyou

 

Ok Battery load test complete steady at 12.2 v with lights and radio on engine off. Looks good under a year old as well.
driving it today so far no notices on an engine traction reduced

 

Which iCarSoft tool are you using? Is it the one with the Jaguar/Land Rover diagnostics? If so, have you checked all systems for diagnostic errors?

 

yes it is the correct tool
a few weeks ago I got a CK engine light which pointed to a possibility bad fuel pressure sensor . I installed a new one and cleared the faults and it’s been good since no CK engine light since then. This has nothing to do to do with the current issue with a notice of reduced traction that’s been going on for years. On and offI cleared the faults and I’m waiting for it to pop up again reduced traction bit of a mystery
On another note, doing a transmission drain and flush. I decided to do it once you understand will take out about 4 L. I’m hoping it’ll make a little difference and at that time I’ll check the fluid what it looks like old fluid that comes out at 91,000 miles on the car it’s my wife’s car. It’s been baby 2012 for the most part in shape. What are your thoughts on the transmission service? I’m a firm believer in servicing all fluids. There’s no such thing as a lifetime transmission sealed that’s a bunch of baloney.
Thank you fortaking a time to respond
