C70 T5 2001 Had this car now 14 months problems started while driving to work 3rd gear 40mph i put toe down alittle and bang it back fired twice no more boost. Volvo diagnosed a bad MAF replaced it and still it wont boost it hits the 3/4000 rpm you hear the turbo whistling away but no power i changed the diaphram in actuator the other day and still same if i slightly adjust the rod its worst . A flat spot has occured on low rpm at stand still just blipping throttle and every morning i start her up its bad ,popping and farting trying to cut out this contiues for 3/4 mins with alittle blue smoke and i mean only a lttle few puffs but as soon as it clears she runs fine.. .I have a friend whos a volvo tech but hes ****e because the volvo laptop is not showing any faults at all he doesnt know what problem is . I have a new ETM on, MAF sensor just replaced, inlet manifold gasket, injector seals replaced, new spark plugs, new pipe clips and all checked for splits , STILL NO BOOOOOST .When i did the work on the engine eg:gaskets and injector seals i had the battery disconnected for around 24hrs so i presume it reset the ecu ?, It ran like a brand new c70 it was buzzing then after about 40 miles these problems have reoccured still no engine warning lights

there are my plugs in 1 week after cleaning plugs tell you alot about your engines condition the red core and white tip isnt good news i think my car is running too hot in some way.but my temp is at normal half way up on the temp gauge If anyone has idears , before i have to get a bank loan for the cost at volvo main dealers it would be goooooood !
