Uninstalling Cobb AP

hp jnkey · 06-21-2011, 07:48 PM

I have to take my 535 in for service and I'm wondering if it's as easy to uninstall the Cobb tune as is was to install?

I haven't had any codes or issues since I originally installed the tune.

Any secrets or special instructions?

Nope takes about 10-15 minutes to uninstall. Just plug your cobb into the OBD port and click uninstall. Just as easy to install and uninstall.

make when you uninstall the cobb, that you clear all your codes/shadow codes.

So you mean that installing the Cobb will automatically throw some codes that have to be removed?

Can I clear the codes with the Cobb AP?

O HELLA BMW · 06-21-2011, 08:55 PM

well i uninstalled my cobb ap, but just to make sure i had a fellow e90 member use is OBD(or whatever its called) to check if i had any shadow codes and i did.

i had a code thats tune related so he erased it. if i were you id get the OBD cable and just check to see if theres any codes

better safe then sry

That doesn't sound right. COBB claims that absolutely all codes are gone when you uninstall. Someone care to clear this up?

It autoclears codes after each flash, whether putting it on, changing maps, or uninstalling.

I also took my car in after having my hpfp throw a limp mode, got a new pump, no problems.

Yeah I didn't think it left anything. Thanks for clearing that up.

yea, there are random reports that folks have seen codes after uninstalling it but those are no very common. There might be certain codes that are missed or persist as they are issues unrelated to the tune. Cobb claims they have had folks with high level equipment note that no trace has been left. But everycar, install, scan isnt the same, so who knows.

Heck, who says the BT tool is perfect? You play, you pay.

Sounds like I'm good to go.

I've personally seen multiple codes (both fault and shadow) still visible after a complete COBB uninstall.
COBB AP "Troubleshoot" menu shows "no codes" but BT scanner shows codes (both fault and shadow)

Don't remember the exact codes off hand, but have them saved on my netbook if anyone is curious.
IIRC, they were related to COBB re-flashing the stability control/transmission module.

I would never own a BMW without a BT Scanner. Hopefully if you own a 335, you can afford to buy the cable.

Deffinately This ^ I BT scan after Cobb it dosen't get them all.

mithiral67 · 06-22-2011, 07:10 AM

When did you see that last. I thought Cobb addressed the issue with the intermodule stuff?

bkrM3 · 06-22-2011, 07:22 AM

^^ +1 can anyone else confirm what happens with a BT scan after uninstall? I have to go in next week and need to figure out (soon) whether to get my car scanned based on the above.

Surely someone else has tried this.

Here were the Current Fault Codes found with BT Scanner immediately after a COBB AP Uninstall about a month ago. The COBB AP showed "No Codes"

D357:
DSC: No message (gearbox 186)
Error will not cause a warning light
Error is not currently present
Test conditions have been completed
Timeout

5E19:
DSC: Engine management: interface
Error will cause a warning light
Error is not current present
Test conditions have been completed

D356:
DSC: No message (engine 170)
Error will cause a warning light
Error is not current present
Test conditions have been completed
Timeout

D355:
DSC: No message (engine 169)
Error will cause a warning light
Error is not current present
Test conditions have been completed
Timeout

D354:
DSC: No message (engine 168)
Error will cause a warning light
Error is not current present
Test conditions have been completed
Timeout

I also usually see the CF33 Transmission Fault Code after the COBB AP flashed the car back to stock (AP uninstalled)

Quote:

After control module replacement, complete vehicle reprogramming, or after clearing adaptations on the engine control module, the transmission may enter failsafe mode with fault code CF33 with the description of "No message from engine management stored in the EGS module" stored. This fault code cannot be cleared. This problem is documented in BMW service bulletin SI B24 10 07.

mithiral67 · 06-22-2011, 12:01 PM

Yea, reflshed this morning an it say it's only clearing drive train codes. So I guess the update to clear all codes hasn't been put through.

bkrM3 · 06-22-2011, 12:03 PM

Mother eff. Ok, BT scan tomorrow I suppose.

mithiral67 · 06-22-2011, 12:08 PM

I bought a used BT Scan tool with 2 empty Vin's , but I need to figure out how to use it.
Any tips?

Litos · 06-22-2011, 04:44 PM

when i got my CEL this is what i did:

1) i checked the codes
2) i deleted the codes
3) uninstalled AP (took less time to uninstall that it did to install)
4) drove around again until the CEL came back on
5) drove to dealer
6) got car fixed
7) drove home and re-installed AP
8) wide open throttled LIKE A BOSS just to make sure everything was working fine
