Today was a little colder than usual at just 32 degrees and I was driving the MY09 GTR between my retail stores that I own to pick something up and on the way a warning light saying "Warning: Engine System Malfunction Visit Dealer" came one. I have all the gears, including manual mode and the car seems fine. I let the car sit a little bit while eating dinner and even filled up gas on the way home, because it was almost empty, yet the code remained. I read that it could be the evap valve, and I'm really hoping it's not the transmission. I got the car with 4,200 mile on it in mid July and have put almost 10k on it as a daily driver. So it gets lots of use. I'm taking it to the dealer tomorrow but curious if anybody has any ideas as to the problem so I can sleep better tonight.

I have heard of folks getting the warning light due to gas cap issues but most likely a sensor. Hopefully its nothing major.

Happened to me.. Mostly the evap canister...

Check with the previous owner if he did replace the defected part...

Good luck

Took my car to the dealer by my house and they couldn't read the ECM. The Gt-R tech there had only been certified for one year so he was extremely unfamiliar with the GTR. He actually confused me and said their was a tune device hooked up to my car and suspected that was the problem. When he showed it to me I just laughed because he pulled out my Tune2Air Bluetooth device for streaming music. I ended up scheduling an appointment with my normal tech at a dealer 35 minutes away on Monday. I hope it's nothing big.

Took my car to my normal dealer for service and I was told when I purchased the car it already had a Cobb Stage 1 setup on it. I didn't receive the AccessPort device when I purchased the car and they are going to try and get it from the previous owner because they may need to revert it back to stock to read the ECM. Are the AccessPorts tied to the car once you use it?

That is lame! I thought you had to unmarry the Cobb to reuse it/sell it?

so hold up are you saying that when ever we take the car to the dealer even for inspection we have to unmarried the Cobb's if so wouldn't that make the car run bad especially if your doing inspection.
The Cobb tune needs to be put back to stock for the dealer to do a diagnostic or do the annual pos service. Ecutek does not need to be "unmarried".

You can sell anything, but the cob won't work. The only thing you can do is contact Cobb and have them do a reset which costs close to a price of a new accessport

If you want to sell the cobb...you have to unmarry/uninstall it from the car. Otherwise you're selling a useless plastic display that doesn't work.

I have no comment as far as dealer service.

don't want to sell just didn't makes sense that u would have to remove it during a diagnostic when its the reason you have it so you don't throw codes just saying ...

At the dealer I went to they had to use a different computer to read my ECM. They said it is the o2 sensor and because they have to remove the turbo it's an $800-900 job. $250 for the part and $130/hr in labor. Is this something I can do myself? I'm a noob with working on cars but I have done some easy stuff in the past. Reinvested every penny in the business to open a new retail location and don't have extra money for this and new tires right now.

Bad O2 sensors can cause a warning so can other sensors. Why are they sure it's the O2 and not let's say for example MAF? Moreover the O2 sensors as far as my 2015 were connected to the downpipes. Thus you don't need to remove the turbos to change them unless the downpipes were cross threaded and they need to be drilled out. Someone can correct me on this if I'm wrong.

Are there any GTR tune shops around your area that you can reasonably drive to? I believe they will be way cheaper!

I would highly recommend having your car looked at by someone who is knowledgeable about the GTR.
