    DME Code 2C9E after clutch install

    Hi. I had my clutch and flywheel replaced (Spec Stage 2+ with OEM Dual Mass Flywheel), and I notice that now I get a regular 2C9E DME code. A bolt was corroded on one of the downpipes and had to be drilled out, and replaced with a new bolt. Could this have upset one of the O2 sensors, maybe dislodged it?

    The clutch and flywheel combination, by the way, is great. I was preparing for the worst but this clutch feels so stock-like that someone could have swapped this without telling me and I would have only vaguely noticed a difference. Now to drive for 500 miles like a granny in stop and go traffic. :@

    I'll probably just get the O2 sensors checked out when the car's in the shop for the battery terminal recall repair. That won't happen until the 23rd though. I will try to keep you updated.

    You most likely damaged the 02 or its heating element. The rear 02s are sensitive to harsh movement or sudden shocks. I would know because on two cars i had the studs snap. I heated the downpipe up with a torch and hammered the broken stud out. After the dp install i had 02 codes come up immediatley.. and they are not cheap :-(

    Erf, yeah, that makes sense. How much does driving with a faulty/broken O2 sensor hurt the engine? I know it manages air/fuel ratios a bit, but I am not sure how critical it is. I'm definitely getting it replaced, though. It will just be in another two weeks.

    As long as the damaged sensor is one of the secondary sensors as @Flinchy indicated above, there should be no problem driving with a bad sensor.

    I am wondering, is this a side effect of having this sensor broken? In low rpm on a high gear, applying the throttle rapidly causes a shudder in the car which sorts itself out in about 1 second. It doesn't do this in 5th gear or lower gears as far as I could see.

    I got the O2 sensor replaced and all the fault codes and misfires went away. I am running a flex fuel map with a sensor and 100% E85 is ridiculous. I've been running 50% for a while, just because I wanted to wear in the clutch properly. With 100%, there is no slip, and the car just climbs through the gears so fast. First gear is gone in a flash.

    So far, so good! It looks like this was the O2 sensor all along.
