How Much To Replace Aos?

[ultramens]

I brought my car to the dealer and they quoted me 1,890.00 to replace my AOS. I have a 1999 C4 Tip. Is this about right? How much should it cost???

Thanks

I know that on the 996 it's a real PITA to replace the AOS. With a TIP it's even more labor intensive. I believe they have to pull the engine to get to it. That's why it's so expensive (labor.) The part itself is around $150..

Remember the dealer is going to be about 40% more expensive than a good independent mechanic. Stay away from the dealer...

Some people on the site have done it themselves. Hopefully they will reply to your post. I would contact some reputable Porsche techs in your area and see what other quotes you can get...

Good luck

I haven't done it on a tip, but with my manual I've done it through the top by removing the manifold/plenum/alternator/airbox/various hoses/etc. It was a major pain to get at all the bolts, especially towards the rear of the 1-3 intake manifold. Then it takes a miracle to get all the hoses connected well and everything put back together.

Also saw how it could be done much easier by just removing the transmission... a much safer bet because you have a better angle to get at all the hoses.

If I had to do it again I would do it by removing the transmission - much easier to get at from behind the motor, however not sure if removing the tip trans is an harder than a manual.

If it is a C4 then it could be harder to get the trans out.

If you remove the motor of course, that would be the easiest way. Duh.

Thanks for the reply, from what the dealer said, they will charge 11 hours labor becuase they have to pull the engine and transmission out.....

I got a quote from an Indy and they gave me a price of 1300. Is this a good price? what have others paid to get theirs done?

[phillipj]

I checked with my mechanic and he said $1300 is a fair price. As you can tell from Logray's post it's a real PITA. Might be a good time to think about and a new RMS and possibly a clutch (if you need one) while your in there.

Thanks for the help....

I had mine changed when replacing my clutch. I know that doesnt answer your question directly but if you want to drive to Tampa, 'vortex will provide excellent service for very reasonable cost. Replacing the AOS was the best money that I have spend on my 02 996C2.

Finally stopped smoking on startup after tracking the car.

Mine died with no warning last Sunday at 140,100 miles. Huge smoke screen across the freeway.

Normally I would have tackled it myself and made a video, but due to time constraints and needing the car running, I reluctantly let the dealership handle it.

With a tow to the dealership it came to $1120 for my 99 C2 6-speed.

It should be noted that the AOS has been superseded since 1999 and with the current part, you have to modify the manifold to create enough bolt clearance. Even Porsche of North Houston did not know this and had to call Germany to figure out how to get things to fit back together.

Just had the AOS replaced in my 2000 996 Tip. On the tip cars, the engine must be removed for this task. My indie mech charged $1300, parts and labor.

I have to vouch for the crew at Vortex as well. Not only are the prices fair, the techs know their stuff but they stand behind their work too. I had a bad water pump bearing on one they put in. They replaced it after 6 months at NO CHARGE!. I expected the part to be covered but not the labor. Also had a difficult clutch-flywheel set up and they went way above and beyond for a happy client.

Call Doug or Sarah for a quote at 813-874-1911.
