Car is super broken........:-/

(This is Long I know but if you have time please read I need some help)


Let me Brief you guys first off.  About 2 months ago My Brother borrowed my Q45 while his M3 was in the shop. While he had it worked fine. The night before I was going to get it back I went to his house and we took my Q out to get some food instead of driving my Audi cause I missed it and felt like driving it. All is well, Next morning my bro says it starts but then shuts off...I was like WTF then I remembered the gas was low. So we went and put gas in the car. Still starts run for like 3 seconds then shuts off. So I say okay maybe MAF I bought one from Infiniti and plugged it in still did the same thing. So as you know that piece is a life fortune (Joking) so I returned it. Agter that I said well lets do a Fuel Filter and see....No go.Then a Fuel pump OEM still wont work at this point the car cranks and turns over but then immediatly turns off (less then 1 second of running) So now I am lost as hell.

Recap of Replaced parts

-Fuel Pump
-Fuel Filter
-Spark Plugs
-Air Filter
-MAF


I end up giving up and taking it to my Local dealer (Jim Coleman Infiniti) By now I am sure it is the immobilizer and I cant fix that myself.

I take it in and now they are saying well we want 3.0 diagnostic I say fine what ever I just want the car running. They tell me it is the immobilizer control unit so I buy one and they put it in BTW total labor is like 5.5 so my bill is close to $600 now. I have been calling since Thursday and no calls back after many many messages to the manager and the service writer. Finally today he is there and answers and tells me that they pluged it in and programed it but the 4th signal wire is getting no signal. I am pissed cause now they want to pull the dash and charge me more. I just feel like they should have figured all this out already not after me spending almost 600 with them.

What do you guys think I should do?

anyways to bypass the immobilizer thingy majiger?

Have you checked NICO? Not to say nobody here is knowledgeable enough but NICO would give a lot of info since that is what the site is about.

yeah bro i posted on there too
