i have a question,
im considering doing the Alpina flash for the transmission, does this in anyway affect cobb? do i need to uninstall the cobb first, then re-marry it to the car after the Alpina flash has been done? im thinking it wouldnt affect it either way - but just want to be sure |

Did you recently update to the newest firmware? I'm wondering if they changed something during the latest update. Maybe Cobb Tuning can chime in.

For those taking their car to the dealer for warranty work, are you all flashing to a stock map or are you completely "unmarrying" the COBB from your vehicle? Or are these actions one in the same?

They are not the same. You should unmarry if you have to go in for warranty work.

Whenever I uninstall or install my Cobb tune, the buttons (all of them) on my radio faceplate stop working. It happens sometimes when I change tunes as well. Anyone else ever had this happen? Dying battery?

Yes. It might be datalog 16/17 that trigger the codes.
It was at about 5000RPM when the codes came on. Sorry I dont know how to read the datalogs.....or what they means. |

please read up on how to do a proper data log it will help your cause greatly.if I had the link I would post it for you but I don't sorry. only thing I saw was some pretty good throttle closers and some pretty good timing corrections in another .

I8AOS 4.01 Drive map Stage 1 BOOST LEAK
Okay. I read up on it.
Disable DTC. Rev to 2500 RPM Hit start Floor it until the half engine light on. Let off on the gas. Hit stop Here's what I got: No other modification to car Stock. Is it common for Boost Leak to occur on DRIVE map? That means i can go higher than 4000-45000 RPM with triggering this CEL? Thanks |

If you're having boost leaks then you are going to have them regardless of the map. On a STOCK car the most likely culprits may be the diverter valves, however try calling some local shops and see if they can perform a smoke test... assuming you don't have any obvious loose connections, of course.

well, at least are not alone.
I assume it is a weak battery. I'm not getting any other funkiness or battery warnings, however. I took it to the dealer for it the first time, and of course, it was working again then... But at least they have a record of it happening. edit- I also very frequently get a 10-30 second delay in the stereo kicking on when I start the car. No sound (not even seat belt gong), display, etc... So perhaps that is also a sign of a bad battery.

I will say after unmarrying and taking my car into the dealership to troubleshoot a very minor hiccup at idle ( happened after installing new spark plugs go figure), my service adviser called and asked me if I had a "juicebox" installed on the vehicle. He then said that he wasn't trying to void any warranties (I'm still in warranty) but his tech couldn't properly diagnose the car because there was no data to pull from or analyze. The tech told my SA he most commonly associated the "way my car was acting" with having a Juicebox installed or previously installed. I of course denied it, because hey I didn't have a "juicebox" installed . Later on, after hearing the SA and tech recommend a particular tune for my car ( not dinan) I felt ok about admitting the fact my car was usually running a cobb tune. My SA then told me to just leave the tune on the car for future visits so they could properly diagnose the vehicle. However, I will say after just blowing a charge pipe, the same tech and adviser denied warranty coverage because it was connected to my aftermarket FMIC. Bottom line, it's odd how dealership's treat mods. You never know what they throw up a red flag for. I have since spoken with Cobb on the issue and come to my own conclusion, drive your vehicle a decent bit before taking it in, after you unmarry it. Otherwise, there will be very little data stored in the dme. Just my 2cents. All the previous dealer visits where I unmarried cobb a day or two before the visit, they never mentioned anything. |

+1 on driving for "a bit" after unvarying before taking it in to the dealer. That's exactly my experience as well.
