Last week, the same error messages appeared in my car as well. Nontheless, the reason behind my error messages were due to plugging the Sprint Booster in the wrong way. I immediately visited my dealer and they've managed to clear all error messages by reseting the computer Note that flashing the ECU was not necessary.

Best of luck and let us know what happens.

One more thing I forgot to ask, does your rev limiter stand at 7000? The reason I'm asking is because mine did stand at 7000 due to the engine fault message. I hope this issue will be resolved as fast as mine did. It hopefully won't take longer than 10min.

RPM reduced to 4500, the car is really weak and sounds extremely weak as well. I tried taking the car to the dealership, but no luck as they have started the "Eid" Holiday already .. i have to wait until next Sunday.

I am wondering what would be the reason behind all these errors! the car has been driven just like before .. no different driving style was used .. i hope its not serious!

I know how that feels. It sucks bigtime . You might want to pass by Yara Center. Ask for Denny. He has worked miracles on my beast

Thanks for the update. I hope it won't take long for the parts to arrive. Out of curiosity, how much is it costing you (parts + labour)?
