Hey All,

So I went a head and purchased the full version of Torque and I'm pretty impressed. There's a lot of info there and the Fault readings give you explainations as to what is at fault. Here's a current fault readout from Torque that I was able to send to my e-mail:

End of report.


I'm not sure where the local shop got the "2b70" fault code but the above is exactly what the shop stated was wrong with the X. Apparently if the weather is very cold the X will start rough and the engine will misfire on several cylinders in order to try and correct the issue. The shop also stated that this issue is a "design flaw" that BMW has in the 4.4 X's. Some have the issue and some don't. It's about $3.5K - $6K to fix depending on Indi or Dealer. However, if you can deal with the shake on the startup when it's cold you don't have to fix it. It's a non issue in the summer. Can anybody on this forum second that?

I'm looking forward to learning more about Torque and all the options it provides.
