I would - it will switch the haldex off, giving you front wheel drive only. But if the problem remains after fuse removal it means you have a jammed up haldex. Jules |

So taking the fuse out causes no harm to the Haldex then? It might help me identify the problem. I suspect I have a haldex problem as when accelerating quite gently from standstill or low speed I get a slipping / jamming sound from the rear of the vehicle. Originally thought it was a chirp from rear tyres as torque comes in ( as you can get on powerful rwd cars) now don't think it is the wheels/tyres but something to do with the Haldex. It is more pronounced in hot weather but doesn't happen if you ram your foot down and accelerate hard. Can the Haldex stick before releasing as it moves to 2wd. Had a new Haldex pump at 48000 but don't know whether they serviced the whole unit or not ( it was a JLR main dealer). It was done as part of the sale deal but I didn't ask for the details as I knew nothing about Haldex systems then. Now on 67000 so a haldex service is due soon anyway.I Anybody got any suggestions?

Says FB1 in my manual too. Yes, you get several alarms popping up. They wont clear after you've reconnected everything until you drive it. Jules |

I had the same symptoms recently and serviced my haldex to find haldex oil level was very low. Cleaned pump screen, new filter and new oil. All good again. I'll check level of haldex oil in future in case it is leaking but never see any sign of an oil leak below it. Landrover - turning owners into mechanics since 1948

Can be many causes. Mine is currently de-fused as I'm getting a shudder under hard acceleration, or when maneuvering on lock. Hyundai Ioniq 5 Ultimate. The family car. 2009 Rimini Red SE TD4. Gone. 2006 Tonga Green i6 HSE. Gone. Audi A5 convertible, my daily driver. 1972 Hillman Avenger GT, the project. |

Booked in to see, Austen on the 16th. I asked Austen if I should remove the fuse and he's response was not to as in he's experience it can confuse the issue. |

Don't really understand that. Surely you just put the fuse back and go test the car. Jules |

I agree. The shuddering is the front and rear fighting each other, which forces the Haldex clutch pack to slip in jumps. This is putting enormous strain on the PTU splines (already a fail point) and the rear diff pinion too (another fail point).

I’ve found the 4 15a fuses in the luggage compartment, but can’t see any lettering to say which is FB1 ? Do they just pull out guess. Forgive my ignorance 😀 |

Well the manual for my 2014 SD4 says "luggage compartment (AKA the boot I presume) , FB1, 15amps, blue, electronic centre differential"
