it will have to be taken to a valvo dealer they can deactivate limp mode with their scanner a normal scanner will not access the systems need to remove the car from limp mode

It isnt on limp mode at the moment as I said I can reset the problem by turning off the engine and starting it again I need to know what is causing it to suddenly happen.
Expert:  cloe0626 replied 1 year ago.

A bad connection in the tcm will cause it to go into limp mode but can't say for sure without it being scanned by a Volvo scanner

Customer: replied 1 year ago.
I was really for an answer without having to take it to volvo for a diagnostic as this will be costly.

unfortunately its a volvo and lot of the computer issues can only be fixed by a dealer i wish i could give you another answer but there is not one i apologize

Customer: replied 1 year ago.
Also its a manual car so it wont have a tcm?
Expert:  cloe0626 replied 1 year ago.

that is true but with out a volvo scanner and knowing what codes it is giving off i really cant help you any more like i said i know you dont want to take it to the dealer but sometimes thats the only thing that can be done i am sorry
