Last year I changed my MAF because of a pcode. So last month my water pumped failed so I did my water pump, belt, coil packs and spark plugs. Now my AOS needs doing. I have p0507, p1128, p1130.
So my question is while my mechanic is changing out the AOS what else should I have him do? Any recommendations?

 

If the tech is going to remove the left intake manifold, it's a good time to replace all the vacuum hoses and elbows, 2 change-over valves and the vacuum reservoir. The parts are about $150 if you get them from Sunset Porsche.

 

What ahsai said. I will probably do that this coming winter.

 

What Ahsai said and also, depending on mileage/age, while all that stuff is off the left side might consider a new coolant tank. I know it adds up but it will have to be done eventually anyway.

 

I appreciate all the input and suggestions. I figure if he's there already might as well have the tech do other stuff. Keep the suggestions coming! Thanks

 

My p1128 and p1130 were caused by clogged fuel return line. (See my other post)
I changed the AOS for nothing and glad I did not change anything besides that.
Check your fuel pressure!

 

Please explain 'clogged fuel return line'. How does a fuel line get blocked?????
