Engine fail safe light came on and idle is now rough, gas pedal not responding

Another option is Batteries Plus Stores. I got mine there and no issues going on 3 years! 510 locations all over the US. Batteries plus.com, enter zip code and see if one is near you! If so, plug in your year, make and model and see what they have available.

Good Luck!!

My BMW branded battery was made by exide.

But from the sounds if it, that is besides the point. He needs to do some real troubleshooting to figure out the problem.

I have the same exact problem. I don't have access to an OBD scanner so I purchased one online today so I can pull the codes. It should arrive on the 29 Aug and I'll post the codes then. Hope to get this resolved ASAP. My voltages are the same as yours and I'm not sure how old the battery is since I purchased the X5 in November of last year. More to follow.

P.S. Thanks for all your help SlickGT1!

I finally pulled my codes and here they are:


P1632 Smart Alternator Faults Sensor/Circuit Malfunction 2012-08-30 18:52:36
P1639 Vehicle ID Block Corrupted or Not Programmed 2012-08-30 18:52:36
P1638 Can Link ECM/INSTM Circuit / Network Malfunction 2012-08-30 18:52:36

Any suggestions?

Hope you can answer my question here, please.

Dont have a clue whether the throttle body normally behaves like this. Should the hole be completely sealed at normal position?

Cheers!

I'm at work and can't see youtube videos. I'll check it out when I get home. As for the butterfly valve in the throttle body, it should completely shut when the engine is off. When the vehicle is running, the OBC makes the adjustments for a steady idle. I'll get back to you when I'm able to see the video.

Thanks

not sure if you can view photos but attached is the comparison between as what i've seen and if I push the lower part further.

That looks fine to me. I think your problem is elsewhere...certainly not the blockage of the butterfly valve. Did you try unplugging the MAF sensor?
