Hi,
A quick introduction to start - I bought a 2007 C4S Cabrio in December (thwarted by snow again so not much use since), it has covered 105,000 miles and had a full Hartech engine rebuild less than 10,000 miles ago.
Incidentally, for those who like to analyse engine failure stats, this had an engine replacement by Porsche under warranty at 40,000 miles, and further bore scoring (and strangely worn crank bearing) requiring a Hartech engine rebuild at 95,000 miles, so at only 55,000 miles on that engine.
So as I haven't managed to drive it much I've been sorting out a few niggles and adding my own touches such as Zunsport grilles, and LED rear lights. I'm also considering front DRL's, but are they really worth it? I've heard you need to turn the sidelights on for the daytime LED strip to work.
One issue I can't resolve is the PCM2.1 won't clear it's memory or retain any new stored destinations etc. I can go through and delete all previous places visited & favourites, and add my own, but after the ignition has been turned off and on again, those deleted places have returned and my saved data has disappeared. It wouldn't be so bad but it keeps defaulting to an address in Poland, so when I enter a destination I have to start by scrolling through the countries back to the UK.
I have tried the 1, 4 & 8 reset, tried latest sat nav & unit software upgrade CD's and also tried removing the PCM from the console so all wiring was disconnected, but when plugged in the previous destinations are still there. Could this be reset with PIWIS or possibly 'flashed' by a repairer, or will it need a replacement unit? It's a weekend car and I'd rather fix this if possible than spend £1000 on an aftermarket unit with fibre conversion.
I appreciate your thoughts.
Thanks,
Jeremy
