I definitely get an orange warning icon on the dash (not talking about the little feb icon turning yellow at top of screen, it does that too), this is a strange looking icon in the odometer where other warnings appear. Screen definitely used the words de-activated too. It has happened pretty much every time I've driven in heavy snow or heavy rain, also happens to a lesser extent in windy weather! So basically not fit for purpose in typical northern UK weather
@
TJ16 That is a common problem, and it's when the forward facing radar can't cope with the additional data created due to the fast flow of snow/heavy rain etc past the sensor. It is not a "fault" it's just a poor system The problem @
mike-b is having is quite different, where the system randomly fails even without the added data caused by precipitation.
No, that sounds like TJ16 is having the same problem that I am! The FEB icon turning orange (temporarily) is what happens when the radar gets obstructed/confused and the it turns off (typically for a few minutes until it re enables itself). You get a quick message on the display, where it says something along the lines of 'FEB obstructed'. This is 'normal' behaviour and a limitation of the system. I've only seen that happen 3 or 4 times.
The problem/fault that I have (and it appears TJ16 is seeing too), is a message comes up saying 'FEB de activated', and a big orange warning symbol comes up in the middle of the rev counter. And when it comes on, it stays on, the only way to make it go out again is by turning off the engine and restarting. It's as per the attached photo - but ignore the other warning lights - they are other faults I've had, and don't come up anywhere near as often since the dealer fiddled with it last time!
The orange FEB fault light is definitely a fault with the system - I demonstrated it to the technician on a test drive yesterday and he agreed that it is definitely not normal. I can make it happen by driving down a long hill with prolonged braking. In fact, I think that's the only time it ever happens, and there are certain hills I can drive down near my home where it happens 50% of the time. Wonder if it happens to TJ's Nav on long descents too?
I know the FEB can be deactivated from the menus, but I don't want to do that:
1) Because deactivating it makes the same orange warning light stay on permanently - I don't want my dashboard lit up like a Christmas tree with fault lights!
2) One day the FEB might actually be useful if it saves me from a collision (not that I have a habit of rear ending other cars).
3) If I ever did have an accident, I can't imagine my insurance company would be very impressed if they found out that I'd deactivated one of the active safety systems that may have prevented it.
4) It's a fault on a brand new 30k motor, and I want it fixed, don't think that's asking too much!
As for the auto headlights (there's already a thread on them, you're not alone:
http://www.nissan-navara.net/61-technical-assistance-np-300/90961-auto-lights.html), you can alter the sensitivity of them in the menu system, but I've found that even the least sensitive 'on later' setting doesn't help much. My solution is to leave the sidelights on all the time (except when you actually want the headlights, and then you turn them on manually). This has two effects - it over rides the auto function of the headlights, and it dims the DRLs down to side light brightness, so a win/win solution! The sidelights turn of automatically when you stop the engine, so it's completely unobtrusive - you don't need to remember to turn them on/off yourself, just leave the switch in the sidelight position.
