Its not to bad to get the combi valves off. There just isnt much space to remove them. Its easiest to remove the whole combi valve and flange off the rear of the head. The valve can be hard to serperate from the flange in vehicle. Also dont drop the gasket.

You will have to remove the pan to inpsect the pump and some of the lines.

The light will eventually go out by itself if the problem is fixed. It can take a while thou.

Regular vacuum line will work just fine as long as it fits tight enough that it doesnt leak.

 

I agree with dankhound. My Audi has the valves on the front and they are easy to get to. When I had the problem, I changed one short vacuum line at one of the valves and everything was OK. I don't know about the reset - I used my VAG Com --

 

I replaced a couple of vacuum lines, as one had a hole in it right by the combi valve. I think while I'm at it, I may just replace all of the lines, they are in pretty rough shape. Is it worth the headache to remove the combi valves for cleaning?

 

I'm so lazy that I do extra things so I don't have to do them over again..

As for the valves-- I'd just do the vacuum lines and see what happens. On the other hand I'd go further if it was a simple step.

 

I wouldnt worry about it unless the vacuum lines dont fix the problem. The valves rarely get clogged and they are kinda a pain to take off.

 

Finally had some time to get under the hood, and replace some of the vacuum lines... a. holy **** is this engine compartment tight! b. this secondary air system seems very similar to the air injection on my Triumph Bonneville (which I subsequently removed, resulting in a much better (cooler, and smoother) running engine, and at least 20' of rubber hose!) any experience with removing all corresponding solenoids, valves and vacuum lines?
Anyways. I am loving this car (although with the Bridgestone Potenza 255s it is awful in the snow, I need to pick up some good all seasons next year). What types of things can I do along the way, such as replacing all of the vacuum lines, as preventative maintenance to avoid major issues.

 

Anyone....[sm=icon_stickpoke.gif]

 

Yep - replace vacuum lines --

I would not remove the air pump unless you want to see a check engine light forever and ever til the junk yard do you part.
