My Ride: 316 ti
n42 no power to valvtronic motor help

hi all done a load of reading and can't work this out i have a 2001 316 with n42 engine

I bought it cheap with eml light on and had 11 codes changed maf oil fuel and air filter now there's only one that comes straight back on it's 2865 on my reader and it's a vanos code I've tested the solonoids by powering then and they both click my ecentric cam sensor had oil in it so it's been cleaned and seems to have stayed oil free. the motor just behind that doesn't seem to get any power even when engine is warm so I think my vanos isn't working there's no difference to engine with any vanos components unplugged either but after fiddling with the plugs it sometimes goes into limp mode and is hard to get out it wont rev atall and makes a kind of bad starter noise on startup but when it's not like that I just have low power under 3k rpm and struggles at take off

so should there be power to the motor and is it possible my vanos isn't working at all
