Alert me when someone posts in this thread:


you and I must be two sides of the alter universe.

I just walked inside from doing the CPS swap....

I too ordered from amazon (on a saturday Morning and it arrived Sunday first shipping!--i usually never buy from amazon for parts, but usually shopthe normal parts places. But this time amazon wins for weekend overnight shipping! my word! awesome...Bosch, made in romania...)

My car showed a crank/no start issue just out of the blue, Saturday morning @ 81k miles (2004 linear wagon)

I opted to start from top (as my mechanic said 30 mins, all from top) but i gave in and jacked car up and finished job from below.... and AND.... i left off the heat shield!

just ran out of time fiddling with it before 9 month old baby duties and dinner called.

Was rather fiddly, and working from below a real neck strain.

I am either going to wait till car is back at mechanics in the next year or so and have him replace the heat shield. OR, I am going to remove the O2 sensor and put the heat sheild one.

With that out of the way I dare say it really could be 30 mins from the top (maybe remove the pipe to the bypass blow off valve too, easy enough)

I didn't have a good o2 sensor socket wrench and i didnt want to disturb too much as i was troubleshooting the no start and wanted to make sure i didnt fiddle with too much else at one step.

Car started right away.

I also second the spark plug wire pliers or something similar... the sensor was hard to get out once screw was removed.

OH! and i lost the sensor torx screw (torx 30) in some bushes (very stupid tired mistake) fortunately I had an M8 10mm screw with 1.0 thread of the same size....

Just now when i walked up steps by said bushes to come inside...there was the torx screw.

My advice is take of the pipe to bypass valve, take off the o2 sensor and just have pretty direct access.

Hard part is lining up the heat shield, the sensor screw hole and the screw and catching the first threads to get it going....

Good luck.

OH and ppps: My 9000 doesn't have a heat shield on its CPS, nor one for the turbo and so far so very good for many years.

My fingers are crossed my Low pressure turbo wont muss up this CPS too much until i can get the shield on.

It would be nice to leave off forever. it's a pain.
