Is there a possibility that you’re using the ECO key?

I’m using the white key

that is the "performance" key

That’s not necessarily true. All depends on what the dealer programs it. My grey keys are the performance keys.

Try the other key. The grey one, see what happens.

What does the dash say/scroll when you go to start it?

His are Gray (white) and Green... They all came as Green = Normal , Gray = Performance on the 2020's.. unless they have been programmed differently.

Time to move to the clutch / belt.

Does anyone know why my x3 will not go over 40 at first it topped out to 30mph and I saw on some forums that could be the belt so swapped it, only difference it made was it let me go to 40mph, I checked my seat belt bypass and it’s working, reset the car still nothing y’all have any ideas on what it can be ? It’s not on limp mode it does have a code for smart lock but I don’t think that would effect anything

Did you buy it new? Or is it used?
Give us more history of the car.

he said he tried another belt (speed went up to 40 vs 30). The code is likely the issue.

Car was totaled over a year ago sat for the year it was getting turned on and off here and there got a whole frame swap everything was fine took it to a second mechanic got a full service done on it was told it was good besides the smart lock being out, went out to glamis for a first ride and that’s is where I encountered this problem and now I’m here trying to find the problem

The plot thickens... So was the battery ever dead after you got it? ever turn over real slow?

By chance did you change ECU?
Something happened as you were rebuilding the car.

The battery was never dead

Something is very fishy about this thread.

We're not being told the whole story.

We tried to help, time for you to take it to a shop

I agree, sounds like a LOT of possible causes/issues.

 

[Reactiions]

Like they said could be may things wrong with it. Try Changing spark plugs and check ground connections.
