39 My exhaust bangs against the rear axle/my muffler hangers brake frequently.
A: This is a common problem on certain cars (e.g., A1 Sciroccos and
early G60 Corrados).
Check the following:
o Realign the exhaust pipes
o Check front engine mount(s)
o Replace the hangers with stronger units.
The most common hangers used in A1/A2 cars up to ~1991 look like
rubber donuts with some rubber in the middle. I bit like an "0".
There are two stronger versions of the "0" hanger available:
840 253 147 A: It looks a tad different but probably work;
171 253 147 G: This looks identical to the original "0" but has
has a chain molded internally and hence cannot be
twisted sideways nor break.
Some cars also use rubber donuts without a center piece:
191 253 147 A and they look like an "O" with a tab on one end.
The newer A2 & VR6 cars use a different hanger system, and those
hangers look more like a piece of stretched caneloni.
o One thing to keep in mind is that stiffer hangers may increase interior
noise (but may prevent your exhaust from bending).
o Instead of using one stronger one, I have had some success with doubling
up hangers.
Tip from Ed W: Do you have a pre-1985 CIS VW? If so, does your car take a
long-time (more than 3 cranks) to start in the morning? If you answered "yes".
Then run down toyour local junkyard or VW parts source and get a
fuel-injection relay from a later car.
The newer relays run the fuel pump when the ignition is first
turned on, thus pressurizing the system. My car now starts on the
first crank when it used to take 3-4 cranks to start.
Your pre-85 VW might already have a newer relay, but if not, I would suggest
getting one.
