strange response
drove 40 miles and a quarter of the tank gone.... .weird.. filled up full again. this is fueled up with premium gas... next day i drove 4 miles and than the throttle became stange... it felt weak and unresponsive. when i floored it, it didnt budge. kind of pushing and stopping response.... weird but than it got better... what could cause these weird activitys?

restricted fuel flow, perhaps? somethink kinked?
or low fuel pressure? leak somewhere? siphoning? any fuel smell, puddles on the ground? |

Is "OEM" the brand name or is it Mahle, Mann ...? If it's the brand name, it is NOT a good brand. There is an aftermarket company selling parts under OEM name.

May sound silly, but you did install everything correctly, right? Not backwards? Sometimes it's the simple stuff that'll get missed.

There is an aftermarket company selling parts under OEM name The OEM part number, which happens to be made by Mahle, I dont think BMW would make there own fuel filter. restricted fuel flow, perhaps? somethink kinked? or low fuel pressure? leak somewhere? siphoning? any fuel smell, puddles on the ground? I dont know why it would be restricted, worked fine for 50 miles. not a problem. nothing kinked. and fuel pump works.... no puddles. smells or leaks... and i dont think it could be bad gas either... and it doesnt feel like a air intake problem either....

Curious why you changed your fuel filter in the first place. Were you addressing some symptoms or just preventive maintenance? Did you have some other work done recently that could be related? Just trying to see if you had no problems prior to your current issue.

if the original wasn't having any problems you could try swapping back if you still have it.

Air pockets in the new filter? May take some time to work the bubbles out.
