Customer Question

My 2009 BMW x3 xdrive sometimes when driving mainly on an uphill goes into a lymph mode? , the car then loses power and goes up the" hill"
JA: Is the power loss consistent, or does it fluctuate?
Customer: I can drive the whole morning and nothing happens and all of a sudden this happens. I can also say I had the actuator replaced and the technician unplugged the 4x4 plug as he stated that the back and front should have diff tyre sizes.
JA: Are you fixing your X3 yourself? What have you tried so far?
Customer: No not fixing myself ,the car runs perfectly and nothing else is wrong just this power loss every now and then? I think it happens more often when the car runs hotter.
JA: Anything else you want the mechanic to know before I connect you?
Customer: no

Hi, I'm Ron and I will be helping you today.

There are numerous reasons that can cause limp mode to occur, engine or transmission etc.

The way to dial in on the reason is by use of a scan tool checking all the modules for communication and codes. This procedure will unveil why this is happening to you.

You can choose a shop to help you or you can borrow a scan tool from the parts store and do this yourself.

Thanks, Ron
