I offer it to the world for appraisal - it took HOURS to write -
do you think suppressing it is "in the Member's interests"?

quattro 2000 update
Bizarrely, the 'bottom end rattle' that developed on the
Nuerburgring turned out to be a top end rattle caused by debris in
four of the cylinders. A rebuild is now in progress. The
stripdown of the Big Red Bus also revealed a split CV joint boot,
although the MoT was only three days old and our examiner is very
strict. The CV joint itself had to be replaced because of a
cracked inner race carrier - three weeks delivery from Audi?
Brake judder and streaky wheels
Sometimes the long arm of coincidence is too long. Having seen the
only three cases of foreign body ingestion we've ever seen in the
last two months, in September we actually saw another obscure
problem twice on the same day! In both cases the external symptom
was radial oil streaks on the rim of the front offside wheel - in
one case extending half way down the sidewall of the tyre. Both
reported brake judder - one car was on its third set of discs in
four months. The true cause was an oil leak on the rear offside
(lower) oil cooler hose union - oil spray was being picked up and
swirled around the brake disk and out between the spokes of the
wheel. If you suspect this, put the car on full right lock and
shine a torch through onto the back of the oil cooler. Key advice
- before you change brake discs to cure judder, perform a run-out
test using a dial gauge - this is mandated by the factory service
documentation. Not all judder under braking is caused by warped
discs - if the discs are not warped, the cause is somewhere else.
