E30 immobiliser bypass
 
Firstly I'd like to thank Chris Deegan, who ever you are, for excellent tutorial on how to swap a dash... I couldn't have done it with out it.

However when I pulled the glove box out the immobilizer switch , which I didn't know I had, broke off. I've cut the wires and bypassed it so it starts but I'm afraid I may fry the ECU.

I'm gonna take to an auto electrician after the holidays and I don't plan to drive it much but I'm worried about causing some permanent damage to the ECU, fuel pump or anything expensive like that.

Any thoughts or opinions on this matter would be greatly appriciated.

Thanks and hope you all have a great new year

Are you talking about the 16 button code feature disable? If you already jumpered the wires on the little black box with the green plugs it should be fine. I woudn;t stress over it causing any damage, when the code is input it simply closes the circuit you bypassed.

Thanks Mate.... Not sure about the 16 button code feature, all I know is the the single button switch desintegrated and the little spring went flying but it is a small black box.

Also I'm pretty sere it isn't a BMW immobiliser but there is an old phone number from the company that put it in, however it doesn't look like a current number (only 7 digits)

Anyway I'm pretty sure it will be O.K but I still want an auto electrician to look at it... just look at it though those guys charge like a wounded bull.

That sounds like a aftermarket alarm bro.

yeah the question now is do I just buy a proper housing and finish the connection properly or get an auto electrician to put a proper switch and re-activate the immobilser.

I'm leaning towards the first option.. I mean if I was able to bypass the immobiliser a car theif could easily do the same, plus as much as I love my E30, it's not the type of car it would be taken by a joy riding car thief.

By-pass the imob (which sounds aftermakrket) but keep the tell-tale on the dash. You are very unlikely to have damaged anything as the car runs.

Thanks mate but now I keep hearing this noise that wasn't there before... in paranoid head I could swear it's coming from the petrol pump but I will investigate this weekend.

After I swapped my dash and killed my immobiliser , which I didn't know I had, I called the NRMA (AAA) and the guy first thought it was the fuel pump so he bang the bottom of the fuel tank.... me thinks he's dislodged all the crap from the bottom of the tank and is slowly but surely clogging up my pump.... I will try to fill my car with premium fuel and maybe add some kind of injector cleaner to see if it fixes it... But I also swap the interior, back seat included so maybe the new seat is not as sound proof as the old one ... but i think that's wishful thinking.

Steer clear of 'injector cleaners' - they don't. Get brave and pull the pump and look in the tank. Fit what you find. New fuel filter and check fuel rail pressure.

jorgE30 01-11-2013 03:29 PM

Thanks for the response mate, I've changes the fuel filter and I'm waiting for the petrol cycle to start again, petrol is up to 20c a litre cheaper,to fill the engine with the good stuff but I'm not sure about pulling the pump out yet... I'm only a new at the DIY business hahahahaha
