Thread: Fault and Limp Mode ONLY when driving about 12km's or around 15mins -- Please Help --

First step is to read the error code(s). Until you have that information it’s all just guesswork.

Lowering is because there is a brake system fault.

Check the wiring harness that runs along the chassis behind the left front wheel to see if it has broken its retaining clip and has been rubbed by the inside edge of the tyre causing broken or shorted wires.

Without error codes it is just guessing. An educated guess from me is get your wheel alignment checked, if the steering angle is off, this faults the abs, esc and most other systems.

Thanks Kelvo. I figured that might be the only way to know.

I do have a cheap micky mouse ODB2 reader however think its probably not accurate?

Hi Graeme,

Thanks for this info, ill investivage this avenue. Strange the faults trigger while driving on the motorway without touching the brake but then again its a Land Rover so sounds like anythign is possible.

Hi Eric,

I wonder if you're onto something here as while driving straight the steering wheel is off center, the car does pull slightly to the left and i have noticed at times what feels like a wheel not balanced.

The below image is the car driving straight.

The brakes are also squeeking now so probably need new pads and discs.

Dude! That screws with all the systems. You must have the wheel pointing forward when driving forward or steering angle sensor will be flagging errors from the TCCM etc. That is likely your issue

Ok, so is this something wheel alignment guys can rectify of does this require adjusting the steering wheel? Im hoping this is starting to sounds like an easy cheap fix.... Fingers crossed !!!
