Hi is your management light on if so what symptom have you got. If not have you plugged it in and just found these codes sitting there

Hi

The engine management light was on and I got the 'depolution fault' message on the dash when starting. I checked and replaced the inlet manifold sensor (p0098), cleared the codes with Lexia and so far so good, no Eml or depolution message.
