So it was the pre-cat o2 sensor that had to be fixed and was messed up and the chargepipe was leaking?
Must be the e85 messing up the o2 sensors and the high boost cracking the chargepipe. How much were you charged to fix the pre-cat o2 sensor? You took it to BMW with the downpipe? My tech said he wouldn't be able to warranty it if it was the o2 sensor since I'm cactless.

So I guess the question is, does e85 have the capability to damage o2 sensors?
Or perhaps it's misfiring caused by the e85 that causes the sensors to fry?
