Audi a4 2.0 turbo won't shift gears properly since replacing fuel injector

Asked by Oct 12, 2015 at 03:33 AM about the 2007 Audi A4 2.0T Quattro

Question type: Maintenance & Repair

I replaced the #2 injector and now it won't shift up into gears until 4000
rpm, and won't shift into passing gear or turbo.  I've driven 60 miles to
reaclimate but is no better.  Can use paddles to shift up and down but
still no power

Automatic but also has the shifting paddles on steering wheel

well my first guess would be to check the transmission oil and make sure its not leaking. A cheaper thing you can do is change the trany filter and fluid and see if it helps.

No can't be that. This occurred immediately after I replaced the #2 injector and put the manifold back in. It did not do this before. I had a cel and that showed I was throwing a misfire code. Diagnosis from mechanic said that #2 injector wasn't functioning properly. I did the repair and with the first test drive, experienced the shifting problems and loss of power.

check to make sure all the wiring harnesses are still connected. You may have jsut missed a harness on reassembly.

Done that already.

ok i been looking around its one of two things, The tcm needs a reboot, in which case you disconnect the battery for 15-30 minutes and touch the cables together while not attached to the battery after 10 minutes. If this does not work then your second likely culprit is a torque converter, This will only be the case if you notice a fluctuating rpms gauge at a steady speed. I recently had something simlure happen to my car. I recently removed the injection assembly hub in my audi and when i drove it a couple times it suddenly would not reverse. I used my scanner to reboot the computer in this case and it fixed the issue. But the above battery trick will do the same thing.

Ok, thank you for this info. I took to mechanic but they haven't figured it out so ill tell them to try the battery or scanner reboot.

kk sounds good

It ended up being the high pressure fuel sensor. It sits under the intake manifold so I must have bumped and broke it when I was putting the intake manifold back on.

that would do it. Well I'm glad that fixed it. There is nothing more annoying then having to remove a bunch of stuff a second time. I recently just did the intake on my old 98 Audi 2.8 and man was that a pain. worst idea to put rad lines under there... :P

Yeah, the hardest job that I've done under the hood yet. Thank you so much for your input.
