hi after a number of posts on here im still having problems??
i have a peugeot 307 sw hdi 110 bhp 2003
it started with car turbo being intermittent but now the turbo dosnt work at all no black smoke and not in limp mode
i had the car put on diagnostic and come up with
po246 boost pressure;low pressure
po100 mass air flow sensor open circuit
p1521 clutch switch signal
ive changed the mass air flow
fuel filter
but on putting the air filter top back on i noticed the clips at the back are snapped off and is quite loose would this cause loss of power???
also noticed the pipe leading to the air mass meter was quite oiley more than i would expect does any1 have any ideas on this thanks darren
