P1449 - Diagnostic Module Tank Leakage (DM-TL) Pump Too High
The vehicle monitors amperage draw from the pump.
The fault is amperage related. You will have to check for any shorts in that circuit. If none are found there, then you likely have a bad DMTL pump which is not terribly uncommon.
I hope that is helpful, please let me know if you have further questions, or if I can clarify anything for you.
It has been my pleasure to help today and I wish you the best of luck with the vehicle.
so it looks like mostly electrical problem. And if DMTL pump is bad where it is located on x5?
In the rear left wheel house.
Please let me know if you have questions.
