longevity of pneumatic locking system (B5 A4)
My car: 1999.5 A4 2.8Q US model, will pass 75k miles tomorrow. Runs
great.
I love my car. But there are a few reasons I wish I had gotten a 2000
or 01. One is xenons (took care of that anyway). Another is digital
clock (yes, minor). Another is electric locks vs pneumatic. My 2000
Jetta had electric, and when I upgraded to the 99.5 A4, I was
surprised to learn I had pneumatic locking.
Does anyone have a really high mileage A4 from 1996 or 1997 or 1998?
How's your pneumatic locking system holding up?
Any known problems?
Preventive maintenance?
Any advice appreciated.
Danke.

Re: longevity of pneumatic locking system (B5 A4)
There are a lot of type 44 owners (1984 - 1991) that have pneumatic
locking systems. They rarely have problems and seem to last the life of
the car which on some of these is now around 300K miles. Once in a while
there is a question on the forums but it is rare.

107K and locks are just fine.

They last forever. If it develops a leak, the pump runs for 30
seconds and shuts off. A couple of years of this neglect seems to
wipe out the pumps.
It is a maintenance-free, very reliable design. I rarely change
parts on a car under 10 years old. Mercedes used a similar system,
same results. It's a non-issue.
At 75K, I'd worry about the timing belt, not the locks.
While you're there. fix that damned oil leak at the timing adjusters.

Good news. Whoops, I passed 74k today, not 75k.
And top posting rules.

Re: longevity of pneumatic locking system (B5 A4)
My '85 4000Q had 315,000 miles on it when I sold it. The pneumatic
locks still
worked great. Any trouble I did have could easily be located by finding the
hissing noise. I don't think it gave me any trouble in the 10 years I had
the car.
My wife's 94 jetta had the same system. It's only trouble was that the
hose in
the rear door-jam came pulled out of the connector once. So, I had to glue
it back
in.
I would much rather splice a split hose in a door jam than repair or
replace a bundle of
broken, shorting wiring harness!
From and engeering perspective, the pneumatic system is much less
complicated, much, much
lighter and more reliable than big clunky solenoids and switch contacts!
