Anyone Know if FL 2's Have a Fuel Cut Off Inertia Switch?

A question out of curiosity really. I was helping out after a minor accident today involving a Honda Jazz - After the accident the Jazz engine would turn over ok but not start and after a call to the local Honda dealer we located and reset the inertia switch which made the car driveable again. Without that info from the dealer it would have been a breakdown recovery job.

This got me to thinking that if I was unlucky enough to have a similar experience in my Freelander 2 then does it also have a fuel cut off inertia switch somewhere and if so does anyone know where it is?

Good question Thumbs Up
Here's a thread from LandyZone (Sorry I'm fetching my coat Whistle ) which has some good detail and diagrams on it to answer your question

Thanks for the reply Westville - I did a small bit of research before I put this query on Freel 2 and I found a couple of replies similar to yours but they looked as if they referred to the location of the Inertia Switch on the Freelander 1 models but I got the impression it's a different scenario on the FL2's - They could be the same though or maybe the FL2's don't have an inertia switch at all??

I don't believe the FL2 has such a switch.

In the FL2 (diesel) fuel isn't pumped from the tank, it's drawn from it by the high-pressure fuel pump which is driven from one of the camshafts. Thus there's no electric fuel pump to keep pumping fuel after an accident - if the engine is off then so is the fuel pump. I believe there is a mechanism controlled via the ECUs to cut the engine in the event of an accident, but as far as I'm aware this is self-resetting (I haven't so far found reference to this in the manual).

I really don't know hence "it's a good question"!
When I get the chance I will have a look around my car to see if I can spot anything like a cut off switch.
I thought one of the others might have put their oar in by now to clarify the situation Whistle

Cheers for replies guys - I can live with that FL2 solution ok.

A lot more than I can with the inertia solution I discovered last night that there is on my wifes 2009 Audi A4 Tdi - Apparently with that car a bump causes a fuse on the battery connection to blow rendering the engine dead until the fuse is replaced (or bodged) and yup you guessed it, in true Audi style, to buy this fuse alone apparently costs something between £100 & £200 from an Audi dealer.

We obviously have a true Audi and are looking to let Audi rip us off at every possible opportunity! (not that i'm bitter and twisted about it or anything..... Smile )

There is mention of a cut off switch in my owners manual (MY11). It's in the fuel section. I don't have it to hand it's in the car.

From memory after an impact it resets itself on turning on the ignition.

I cant find any reference to fuel cut off in my manual (MY2014)

But I did find under " After a collision" on page 196 it mentions the EDR (Event Data Recorder) which gives info on speed , seat belts, brake & accelerator position in the 30 seconds prior to collision. Jules

Interesting about the EDR. I hadn't noticed that before and it also says

"Land Rover do not access event data
recorder information without obtaining
consent, unless pursuant to court order or
where required by law enforcement, other
government authorities or third parties acting
with lawful authority.
Other parties may seek to access the
information independently of Land Rover"


Presumably including insurance companies. driving on the right side

Most cars post 2005 record data in the airbag control module. It's just accessing that data that is the issue!

I have located the section you refer to, and there is indeed such a mention.

Although it doesn't specifically say so, given the description this seems to refer more to the petrol version which does have an electric pump in the tank pumping fuel under pressure to the engine. The diesel draws fuel from the tank using an engine-driven pump, with the in-tank electric pump simply keeping the collection canister (in the tank) topped up and balancing the fuel on either side of the saddle. I can, however, find nothing which indicates whether this cut-off is fitted to all models, or just petrol.

Yes Pab that is the conclusion I have reached. The only point that stands out to me is it's not switchable apart from with the ignition.

I was certainly unaware of the widespread existence of these devices and have been having a look at the Transport Research Laboratory's 2014 report on EDR benefits, commissioned by the EU

(https://ec.europa.eu/transport/sites/transport/files/docs/study_edr_2014.pdf)

One of the benefits could be the influence on driver behavour IF ONLY the driver knew of their existence. I just wonder why (as the report confirms) they are not better publicised and most car drivers are therefore blissfully unaware of them.

I take your point about ownership and access to data but in the interests of safety development and accident re-construction it really ought not to be an issue. As for apportioning legal blame I'd be surprised if access didn't already appear somewhere in the insurers small print. driving on the right side

I do have a petrol fuel FL2 i6 HSE. Owners Manual talked about "Resetting the Fuel Cut -off". It obviously didnt mention the existence of a SWITCH. See below procedure

FUEL CUT-OFF
The fuel system cut-off forms part of the
Supplementary Restraint System (SRS) fitted
to your vehicle. Following an impact, and
depending on the severity, the fuel pump may
be switched off.

Resetting the fuel cut-off
1. Switch the ignition off and wait for one
minute.
2. Turn the ignition on for 30 seconds.
3. Check the vehicle thoroughly for fuel leaks.
If a leak is detected switch the ignition off
immediately.
• Do not start the vehicle if a leak is
present. Seek qualified advice, and have
the vehicle recovered.
4. If no leaks are detected, start the vehicle.
