brick wall on tick down

[heyes]

Hi Just got the 850 T5 auto and when I sometimes tick down the engine does the hitting a brick wall thing. Also the gauge doesn't appear to move. It boosts normally through the gears but when I hard tick down it does the brick wall thing. Having had Saabs before I would think either a loose hose or sticky waste gate actuator. Any thoughts would be appreciated.

sounds like your hitting the boost/MAF limit to me. Yes it could be the actuator/wastegate stuck closed or have you got an MBC fitted?

mine hitting the boost limit

Yeah, what pedro says, could be wastegate actuator or the wastegate sticking, or a pipe to it could have broken

Hi Got the serviced today and all is going well. There were 2 codes come out 1. 4.1.4 and 2.3.2 and the boost dial doesn't move. Help!!

414 is boost pressure regulator to high (ie hitting overboost)
232 is long term fuel trim at limits at idle (no idea)

the boost gauge is ran off a vac line from the vac tree, i'm sure its a white pipe & normally comes apart at a joint behind the passenger headlight

232 i think could be a vac leak or pipe off,i had this code come up when messing with vac pipes while the engine was running,so could possible be the gauge pipe not conected.

Thanks for info that's what it was. Question should the needle go all the way into the white as my does now.

no worries, on a standard car it should go about 3/4 to the end of the white on the gauge

p fandango beat me too it lol.
