4 Gallons of DEF -> 2k Miles.. No Fault Codes
Anyone have a clue how to get BMW to fix this? They replaced the DEF tank 3 months ago and since then I've been blowing through the stuff. first 1 gallon in 200 miles, now 4 gallons in 2k miles. only mod done to the car is a JBD @ 8/10. Only fault code in the system is for low DEF.
I just fear that without a fault code they'll say nothing is wrong. argh. |

Are you sure they filled it up? Don't laugh, this happened to me -- I thought there was a problem but it turned out they had only filled the active tank.
