Hi guys, 

 

Just wondering if anyone has ever fitted a killswitch to a modern car?  I fitted them to older cars years ago - simple enough to wire in a switch, hidden somewhere, which must be put in the correct position to allow the fuel pump to operate. 

 

Can the same be done on newer cars? Mk III Octy specifically?  Keyless entry and engine start is worrying...

On a CR diesel I wouldn't fit the kill switch to the pump, you have a Bosch CP4 high pressure FP which doesn't like being turned over without supply fuel. 

 

My advice would be to fit it to the engine management fuse or similar, that way it won't start without the risk of damage to components.

You will probably generate a stored fault code everytime you use it, but it will only show on a diagnostic scan not on the dash.

Its the same as if you don't plug anything into the AUX audio in, there is a permamenent 'open circuit' fault code.

 

 

Need to have expert advice on that to avoid damaging the car or components.

When real 850 cc BMC Minis had the dreaded SU electric fuel pumps, , I wired up a spare floor mounted dip switch in the boot, in series. I parked my car in a remote part of the Scottish Borders and went for a hill walk.

Heading for a pub afterwards the car stuttered to a halt, about 4 miles later. I gave up that idea . Searching a 4 mile radius for a stolen car seemed too big a task.

Cheers for the replies guys!

 

the situation certainly seems to be more complicated than it used to be! 

 

Do you think fitting kill switches (without causing fault codes) is feasible at all anymore?

A massive ball ache but at least it keeps supplies on all the time preventing error codes

Presumably, the auxiliary fuse would blow when an attempt is made to start the car. Then you have no protection for the radio code etc. which may be only a minor inconvenience. But if someone had accessed the car interior they may then open the bonnet and start looking around. Sounds "negative" I know.

What have you got to worry about? I reckon the badges 'Skoda', 'Octavia' and 'Tdi' stuck to the rear of an estate car in Elegance trim would be enough to put any potential thief off. 

 

Seriously, if you're concerned about things like that, why not just buy a steering wheel lock? or gear level lock? 

@gregoir Radio code? you don't need one of those in this day and age

Unless you own a Ford.

Cheers for the input guys. I guess you're right, more than likely no need to worry

I have ghost fitted after someone broke into my house and stole my 230.

 

Tracked it and recovered it myself but ghost give me real peace of mind.
