When I emailed Beisan they recommended looking at the o2 sensors. Are you guys using OEM o2 sensors or going aftermarket? Real oem calls for over $200 for an OEM sensor.

Those of you looking to replace your pre-cat O2 sensors (whether because you've hit 100k miles, you have error codes, and/or you're looking to get rid of the 2800 rpm issue, have a look at this thread before you buy -- you'll save some bucks. Short version: Amazon, buy 2 of the cheaper one (they're the same - see post #30).

Good call, I'm going to pick up a pair of 215's.

I'm weird about what parts I will use aftermarket on...I will most likely just get my sensor/s from BMW
My garage: 08' Alpine White 135i Coupe putting out 405 wHP to BOTH rear wheels. 05' LeMans Blue X5 4.8is that I like to call Truckmeat. Socketheads 05' Dinan tuned ZHP, and a few Hondas to keep it real.
I ordered a pair of the 215's from autohaus and then bought the tool (along with a few other things) from ECS tuning. I'll provide an update when I get it done.

Are you getting any O2 sensor codes?

FYI, the technical info posted at the link above is BMW service information bulletin (SIB) 12 08 05.
Would be interesting to see cparker here go that route (software update) prior to new O2's, tho it still wouldn't explain the issue with kpro's car.
OP: what's your mileage?
Kpro: still questioning whether yours got the appropriate update. The tech doing the work has to be very specific about what he/she requests of the system, as described in SIB 12 08 05.
I agree, if I were cparker I would try the update before replacing any more parts. It seems as though the update curing the miss is usually on ZHPs more than any other models/engines so that might be why it didn't help Kpro. It also seems like a lot of the ZHPs are the 04 model year for some reason.
