Leaky 85 Quattro - fixed?

Posted on 15 Feb 18:51

It's been winter for too long already so no driving the 85. No working on it either as our 83 rally build and wheel sales have been keeping us busy. We have been picking away at the hydraulic system leaks however. We easily sourced some new pressure switches for the hydraulic bomb and quickly replaced the one on the side. However we did manage to disconnect a wire in the process.

The one underneath was a different prospect requiring us to access it from below. This, of course, took many, many weeks to get round to until recently when we finally drove it onto some ramps in the showroom.

where it sat for another couple of weeks till we had time to crawl under it. It soon became anther classic Audi "unscrew the simplest thing, if you can" project until we found just the right 24mm deep socket to get the switch off. At first we tried loosening the bomb from it's moorings but you cant undue these two nuts even though you can see them:

Finally found a thin wall socket that fit.

This still left the wiring issue to fix.

Think this is where it came from.

This puppy cost $35! Well, it was free, but we had to buy $35 worth of zip ties to liberate it from the box of 100 we were supposed to buy.

Soon had it on and back on the switch.

Of course we can't tell if it's solved the leaks till we drive it and it's still too salty outside. Never mind, now we can fix the leaky rear diff. However, this involves putting it on the lift and you now how long it took to get it off there last time! Wish us luck.
