Ipe exhaust valve doesn't open!!

[Mo-benz]

Hi all today i rather been quiet on the streets, this is due to the ipe exhaust valves not opening for some reason , I'm not a techy guy but want to know what could be the cause of it, it was fine the day before , and it stays off . You can still here the electronic actuator sound click that signals the valves to open when you press the "on" or auto / off" remote button!, its just not opening. In my mind I think the vacuum pipe must of of come off or split from inside , not sure if it did and would affect the whole car in any way but want an opinion from you guys .. Thanks

I had this. It's easy. You need to get the connection to the drivers pedal checked and secured. Where did you get it fitted - MSL?? They fixed mine permanently
