Disconnect the spoiler transmission (attached to the motor) and see if the spoiler will move. Also while the transmission is disconnected from the motor see if the manual operating switch activates the motor

When mine did this it was the bearing in the transmission (Porsche used an unsealed bearing which after time rusts out) . I waited too long and the motor burned out. At no time did the fuse blow..The bearing can be replaced, quite a few tutorials on it around the web

You can either use a 24mm crowsfoot to remove it in place or you can lever the unit off the engine case and then remove the sender on the work bench. The sensor housing is sealed via an o-ring.

Disconnect the wires and pull the unit out with your hand. Clean the area first so nothing yukky falls into your oil reservoir. It's held in my a rubber 0-ring.......... Replace this too, its about $1!

The unit can then be held in a vice while you undo the nut.

The console switch has power, and with the motor disconnected, the wing can be raised by hand using the gears. looks like the motor went on it.
Between this and the spoiler top cracking on me, I am inclined to put a fixed wing on it...

Mr.Alex

This.

I was kind of dreading having to do it, but it turned out easier than I thought. I didn't even touch the intake stacks, just removed the AFM and reached around. Unless you have seepage around the housing (meaning O-ring is leaking), I would just go this route. I bought the cheapest crowfoot I could find, believe it was from SummitRacing (no affiliation), and it worked like a charm. Just make sure to have it sit around the sensor well enough so you don't strip anything.

my car is lowered and i just have 225/45/17's on cup i's in the front but on full compression something is cutting into my tire - i believe someone wrote about a fix - perhaps removing one of the screws that hold the liner in? might just be the inner fender and i need to roll it.

creaturecat

did the car come with 17's from the factory?
there is a steering stop upgrade, if not.

Dreamstate

Is there a method to disable the after-run feature of the blower fan? I would like to keep it intact and have it run while the car is running.

Mr.Alex

Are you rubbing that driverside corner at the joint between the bumper and fender? There was a TSB for cutting the tab there if yours isnt already. Otherwise you might need to roll that edge, which is what I'm trying to do this winter.

Don't quote me on this, but I believe there is a fuse for it in the fuse box in the engine bay.

I just purchased a used cup pipe but it didn't come with the two straps...can I use the factory straps from the stock primary mufflers for the cup pipes?

Ordered new front axle lock-nut for my 89 C4 (999 090 008 02) the part was superseded to: 999 090 010 01. The new axle nut is about half the height. Whats going on?

robt964

Yep its normal. It's come up for discussion a few times on here.

^ Nothing wrong with lighter weight!

964Andrew

Great, Im going to have to replace the other side as well to equal the weight savings

Related: The factory manual calls for 339 ft-lb of force to tighten the nut. My largest torque wrench goes to 250 ft-lb. Not wanting to spend $500 for 3/4 inch heavy duty torque wrench I turned to math calculations: http://hyperphysics.phy-astr.gsu.edu/hbase/torq2.html - Using my weight, gravity and 2 feet extension. The problem with that is the new design of the nut - it doesn't have enough surface to support the socket so I can freely stand on the extension.

Or I could just use torque multiplier.

Any help much appreciated.

Thanks!
Andrew
