Cobb Stage 1 Sport throwing code

azeemtn · 01-31-2012, 01:10 AM

Guys,
My Cobb AP is showing Code P2EF4, Map Controlled Thermostat, Mechanical

I can't seem to find this code listed anywhere..

Is this my system telling my my thermostat is shot, or is this something I may expect to see running the AP?

Thanks

Yeah something like that, has your car been running hot or any coolant lights?

azeemtn · 01-31-2012, 01:08 PM

Not running hotter than normal, and no cooling lights, just the cel and that code..

I had the same code, its the Thermostat stuck open. Brought it to the dealership and they said its a common issue. They replaced the part under CPO, reinstalled COBB. Car runs perfect! Good Luck Bro!

Yes, Stuck Thermostat is what it was. Perhaps we can add this code somewhere for others in the future (or they can search!).

Thanks All

Dealer didn't mind you were COBBed....and just replaced under warranty?? DO ALL DEALERS NOT CARE ABOUT ECU UPGRADES???

Or you uninstalled and reinstalled and they had no idea??? muhahahha??

He said that he "reinstalled" Cobb, so I'm guessing it was uninstalled when he brought it in.

Just got this code today
Guess I have to change my thermostat ? Or wait to see if it happens again ?
Perhaps I should do the water pump as well ?

Suggestions please

im getting this code now too p2ef4 do u guys know if its covered under the bmw powertrain warranty?

If you do end up having to replace your tstat I would strongly advise replacing the wp since it's such a pia repair to do. The tstat attaches to the wp anyways.
