Did the reset. Started up without a problem.

Did a little bit of driving got it to normal temps. and did a hot start.

AP reads
P0040: Upstream Oxygen Sensors Swapped From Bank to Bank
P2C24: Lambda probe before catalyst reversed
P29D0,1,2: Misfire in 4,5, and 6

Didn't do the DPs myself because I don't have to tools. Had my exhaust guy do it. But looks like we just need to switch the O2s around, right?

qbuilt · 10-12-2014, 02:36 PM

Typical faults for incorrectly installed O2's.

Humann · 10-12-2014, 02:43 PM

I didn't even think O2 sensors could cause that big of a problem. Crazy.

Learning something new everyday

Ohh woops.. 53k on my coil packs

I got about 7k on my plugs

Welterweight · 10-21-2014, 01:55 PM

I recently got a Vanos Solenoid code thrown and plan to install two new ones as they are most likely original and I am at 67k. My question relates to the Cobb and the ability to view the required and actual values for both intake and exhaust on the Vanos. Should the values or actual match the required? My Exhaust is almost dead on. The intake is however quite far off. Thank you!

Draven · 10-24-2014, 10:08 PM

Anyone mind taking a look at my log? I did a WOT around 12 seconds in (line 180) and got 2 codes on Stg1 Aggressive... Misfire 3 and 4. Dealer recently swapped out 3 coils recently (I need to look up which). I then reset everything and tried bumping down to Stg1 Drive, then just got cyl 3 misfire. I'm probably going to swap all 6 around (1-3 to 4-6) and see if the problem follows the coils. Car is a '10 with 33k miles. I've never done plugs or carbon cleaning, just the 3 coils the dealer did.

That said, can someone recommend plugs for our application in case the problem isn't the coils?

Aerotest · 10-26-2014, 08:36 PM

Can someone tell me the what the flash times on the V2 and V3 are? Trying to decide which unit.
Tks,

Tks,

V3 after the first flash is 20-30 seconds, but I wouldn't say the flash times would be the reason you would get one over the other since you shouldn't do it very frequently. V3 can log more and has a nicer display with the ability to display 6 parameters simultaneously, that would be the reason to go V3 in my opinion.

Aerotest · 10-27-2014, 08:53 AM

Thanks! How long are the reflash times on V2? I am doing a lot of flashing and I want to get it short as possible. If v2 is a min or two I can live with the difference for the price.

ashmostro · 10-27-2014, 09:22 AM

V2 is about a minute

Aerotest · 10-27-2014, 10:13 AM

Awesome. Thanks to both you guys.

MDORPHN · 10-27-2014, 10:17 AM

I'm not sure whether there's a significant difference in download times.

V3 has a nicer screen, but I don't believe that it logs as many items as V2.

does the v3 really log more? i know it can display more but i had to remove some parameters to log with the v3 that i didn not have to do with the v2.. and that is only displaying one thing on the screen

Hi guys, I recently got in touch with a tuner and he sent me a new map for my 08' 335i. I have an older V2 but have never had any issues with it before. Anyway, I tried to load the map on my accessport multiple times, in several different scenarios, using drag and drop, zip unzip, resaving in ATR, Renaming, etc.... I cannot get the map to show up as anything but grey and locked on the AP screen when trying to install. It shows its locked to a S/N that matches my own. I've spoken with Cobb a little bit about this and they have made a few suggestions which I have tried and they have been unsuccessful. Does anyone else have any experience with this? Or seen this issue?

I would talk to the tuner who made the map. When I upgraded from a v2-v3 my map was locked I had to tell the tuner and they sent me another map and worked fine
