It isn't that this isn't a fairly common issue with the 2005s. It's that it's even more common that the dealers don't properly diagnose the problem and just throw parts at it.

This is the purge valve - pic taken off the forum. They become noisy with age & a replacement will be quiet. Mine is still quiet after 7 years. SA production cars have the valve rubber mounted to reduce noise. If you can stand the ticking no harm is being done. The purge valve is part of the EECS set up & could be the cause of your code. Don't go rushing out and replacing the carbon canister. Many have been replaced & it has made no difference. If it is saturated with fuel it will dry out all on it's own. If you have an EECS leak then it needs to be diagnosed with a smoke test. It could be something as simple as a new fuel cap being required. There is a complete DIY thread on replacing the carbon cannister on the forum. (Coupe but really the same)
We need to know exactly what codes your car is throwing. The OBDII plug is under a little rectangular flap under the steering column inside the cabin.
