OBD lock

I saw in a BMW mag that NV Motorsport are doing an OBD locking plate that makes cloning a key quite a bit more difficult. I think we've all seen how easy it can be on Utube with this & I phoned them to see if they did one for a Z4 (E89) as the panel it fits on is a different profile to the other BMW's. They advised that they are going to make one soon & that it should be available in about 6 weeks time. Anyone interested can ring them on 01214487515 or 07794345483. I'm certainly going to fit one when they are available, there website gives some good info on it for anyone interested.

The price is about £90 and I have the software update! The question is how long before the criminals crack that! A good old fashioned lock will slow them down or (hopefully) put them off!
 
Whilst a good idea all these are purely deterrents. The surrounding trim is plastic so wedging a screwdriver in the gap would see it come out. They're not going to be bothered about damage to a panel if they're getting a car.

If some scum wanted it badly enough they'd be prepared sufficiently.

I had a pair of wheels attempt to be taken from my first smart. I had some form of security bolt on there, but judging from the way they took it off, hammer a socket over it and it came off.
 
If you really wanted to be certain, then a switch, cut into the signal line behind the port, would be my suggestion. Cut the wire, run it somewhere else and fit a secreted switch. Just flip it on when going in for service and off when not. Thieves are not likely to start taking the port apart to find the issue.
 
switch on the power to the fuel pump is a good bet.

I did this on my 3 series. However, I got so used to flicking the switch when I leave the car that I did it when I left the car at BMW for a service...

err, queue baffled technician appraoching me in the waiting lounge then... :rofl:
 
I've extended the odb socket and relocated it on my mum's 335i e92.

The only way I can see the problem having the best preventative measure.
 
Simplest fix is to place an in-line microswitch on the cable to Pins 5 or 8, and to locate the switch on the passengers side of the transmission hump. this will disable either the signals to the computer [pin 8] or the signal ground [pin 5]. Disrupting pin 8 still allows the system to power up, but they will be sitting there a long time waiting for a response from the car, hopefully long enough to get caught, or to believe their device is faulty and to hoof it. And if you forget it, it has no effect on normal operation, only trying to get a signal out of the OBD port.
