Had my 99 Passat in a couple of weeks ago for what VW called a "track rod
end recall." The garage said it involved work on the track rod ends,
steering geometry and alignment. Since then, have just been using it to and
from work on country roads. This weekend, however, took it up the
motorway and there now seems to be - how can I put this? - a sort of
rumbling noise coming from the front of the car that wasn't there before.
It's very low in the audible frequency but intrudes into the cabin as a sort
of booming noise akin to something maybe catching but it's difficult to
explain in writing! Not being technically minded and not really knowing what
the garage did for this recall, just wonder if anyone could shed some light
on whether the 'new' noise could be connected with anything they did? I'm
going to take it back to them next week and try explaining it - and will get
someone to come out with me to see what I'm on about!

Gordon,
Apart from double-checking anything mechanical that was worked on, have a very careful look at the engine undertray, which if not fixed in place correctly can cause aerodynamic ressonance at higher speeds, or could even be moving against the chassis.
Good Luck, Adam

I should check for loose wheel bolts aswell. It wouldn't be the first time!
