O2 not fuel pump.

I have my car back. It sat at the shop since April 25th. Bad fuel pump. They were tinkering around trying to solve the issue while waiting on the pump. Codes were now saying o2 problems. I am no guru by any means so bear with my explanation. "It seems it is not the pump, after they already told me it was, it is your o2 senor(s)". I think there are 4 in there. Long story short, it seems to be running fine. I will let everyone know if she craps out again. Strange to say the least.

Same as everyone elses, except no hard starts. Shuddering, limp, loosing power at highway speeds. What is weird is they even said, your pump is cooked. I am back at work, but took it out for some spirited testing. Car feels great. I spoke with a BMW performance tech and he just shoke his head in a confused way.
They put 2 new o2 sensors in.

gonzo a few questions:

1. When you say "losing power" do you mean the car shutdown, or the same as "limp mode" (ie. reduced power)?
2. Is your car MT or AT?
3. When it shuddered, was that only at start-up or during the ride etc.?

Maybe it was a PROcede issue? I'm assuming that you don't have the PROcede installed now and it's running fine?

I am not ever in the mind set of crap battle. If you have a valid ? then ask it. The car is running great. You guy's are on your own for the rest. :rocks:

1. Reduced.
2. AT.
3. None at start. Every other "symptom" of HPFP.
Just got in from a long day. The car is running fine, listening to some Stones Live, bye bye. Mine is a freak of nature from what I can gather.

Since the PROcede is laying on my desk ( yeah, my car's delivery delayed ) my coffee machine broke. I think this is a PROcede issue.

I would ask for a completely new "MODule"... If you put your old one back it could fry the O2's again... it could be some sort of internal problem in the "MODule" that caused it, rather than just wiring.

Hmmm.. bluetooth-enabled light-speed coffee maker I think you voided your coffee maker's warranty, "gotta pay to play" and all that jazz
