Subject: '91 200Q coil high tension lead.

I just noticed that the black rubberized insulation/coating on the coil
high tension lead of my car (3B engine) has chipped off from the top of the
push-in connector at the coil on the firewall. This is the first I've
noticed anything unusual there. It's possible, I suppose, that it melted
from heat, though the pinkish colored hard plastic part of the connector
(which shows underneath) doesn't look burned. The engine runs fine, and
there are no obvious indications of a problem, except for what was exposed
by visual inspection. But methinks I should replace the high tension lead
Does anyone know if it's possible to purchase this lead without buying the
whole, hideously expensive plug wire set? The other wires are fine.
Insights on this are appreciated. TIA.
Audi sells each wire individually; from what I recall, each one is about $75
list. Bosch lists an application for the 3B; I bought it, but it didn't fit
(wires too short, connections to plugs extend up too far for the cover).
Magnecor makes two separate sets that fit fine (7 and 8.5 mm wires). I think
their website is www.magnecor.com; mention the quattro list and get free
Of all the wires, the one from the coil to the cap is the most likely to match
other wire sets (audi or not). I'd take your wire off, and take it to a shop
that sells separate plug wires, and look for a close match. Failing that, try
Magnecor to see if they'll sell you a single wire, or bite the bullet and buy
one wire from Audi for 1/2 the price of a new set from Magnecor. Another
option, assuming that only the insulation is missing, would be to use a liquid
rubber/insulating compound to rebuild the damaged insulation.
