My 2001 A4 1.8 Audi fail the emission test due to my check engine light is
on. The Jiffylube guy stated that it's a "p0011" error. The voltage
signal from camshaft "a" position sensor in bank #1 indicates inadequate
Does any one know how to deal with this kind of check light problem?
Can I buy the part and change it on my own. Or is it something I need the
mechanic to take the car a part and change it for me?
Thanks for any input.
