Throttle not so responsive... No power

toni8284 · 04-14-2009, 05:09 PM

I have a 09 135i with 1700 miles on it. After I did the modified CDV and golf tee mod, I feel like my throttle not so responsive... I bump the throttle halfway down to the floor, it only goes up to 3500 rpm...

Will it be HPFP issues? Anyone had any advice?

Sounds like a fuel pump to me.. but could be the ecu pulling timing for some other problem. Have the dealer check it out

Push the pedal all the way to the floor! If it doesn't redline then you have a problem =)

Don't tell them about the mods! Just give them the symptoms, let them figure it out. It definitely isn't because of the golf tee mod and I doubt it's because of the CDV, unless you let a lot of air into the clutch lines and didn't bleed them.

I did bleed them. I search from the forum, saying that golf tee mod will affect the performance a little bit. Is that true?

Retrace your steps. Remove all of the mods, and ensure that everything is tight. Sounds to me like you have a leak that is screwing something up. Any CELs?

Not entirely true, my HPFP went out and I didn't have my dash light up like a christmas tree. Matter of fact I just had problems starting.

MOCKBA · 04-15-2009, 11:26 PM

HPFP problem is known for MY08. 09 should be fine and 1700 miles is too low to the problem even for 08. I have 3000, and pump is still working.

the computers tell all. the dealer will hook it up to their computer and get a tamper alert.
