Grant, good to know.

Now there is talk of engine replacement and bad PCCB's.

Porsche could put an end to all this speculation by being up front with the problem. Their cryptic non explanation to the dealers does not engender confidence that they know what the problem is.

If they follow the workshop procedures to the letter and replace the specially coated one-time-use-only fasteners where they need to, then none at all. Audi/Lamborghini is no different! The first step in EVERY single workshop procedure is, "Remove Engine"! The Audi A8 is the absolute worst of them all... Change an O2 sensor? "Remove Engine". SAI port vacuum line? "Remove Engine". CV Joint leak? "Remove Engine". 2" plastic water pipe on the oil cooler with an under-spec'ed o-ring that fails if the thermostat sticks? "Remove Engine". The first step in the "Remove Engine" section; "Remove suspension" The chassis engineers and the engine designers and the gearbox specialist all seem to live in their own little bubble. They should all be forced into an unheated garage during the middle of a Canadian winter and not allowed out until they go through and perform every single workshop procedure from the series previous model. And maybe then they would stop trying to be cute and clever with their packaging decisions!

Nick, the "talk" of engine replacement is pure speculative BS from one or two internet posters with no first hand knowledge of the issue. The PCCB's aren't bad. There is a potential issue with tolerance between the backing plate and the rotor that "might" cause a minor ticking sound but has no effect on the performance or safety of the brakes. Out of an overabundance of caution, Porsche is replacing rotors in affected cars.

Did you read that GM is recalling 780,000 Chevy Cobalt and Pontiac G5 models from 2005-2007 because of faulty ignition switches that have caused 22 crashes and 6 fatalities? It apparently took them years to come clean on a problem that surely they were getting whiffs of for a long time. What companies that you know of provide the public with immediate inside info on problems with their products? In comparison Porsche's response to potential issues with a brand new model have been pretty swift. We'd all like to be getting hourly updates direct from Porsche AG but that's just not how it works.

Sorry for the rant, but there truly are more important things in the world than whether my $150,000 toy is going to be held up for a couple of days for a part replacement. We all need to keep a little perspective and relax.

@ Nick, no biggie. Engine R&R is just a bunch of bolts. I'm more concerned about removing door panels and the like than I am a motor/transmission.

Whoa, is that true? That's crazy. I remember I had a V6 Chevy Monza when I was a kid. Had to partially remove the motor to replace spark plugs in it. Nuts. Something I expect from GM but not Audi.
