I have a 2007 New Beetle 2.5 with about 137K miles and an automatic transmission. The CEL has been on for ages and I have finally gotten around to trying to deal with it. I'm a pretty handy DIY'er, but am mostly familiar with BMWs. I'm lost when it comes to dealing with VW issues - which is part of why I put it off for so long.
Anyway, along with the CEL, I've been having a weird problem with the car and they must be related. Whenever I put gas in it, it is very hard to get started. It will crank, but not start. I have learned to floor the gas pedal while cranking and then it will start. Obviously, this is not ideal.
I scanned the codes and am getting this one: P0455 Evaporative Emission System Leak Detected (Gross Leak / No Flow)
According the research I've done, this is commonly caused by a faulty gas cap. So I coughed up 40 bucks (!) for a new cap from a VW dealership. And people complain that BMW parts are expensive!! I installed the new gas cap and cleared the code. Now the CEL is gone, but the "Gas Cap" warning light is on instead. The same P0455 code is showing, though. So the problem is clearly not the gas cap. More research points to the EVAP Purge Valve as a possible suspect. But before I throw any more money at parts, I'd to be able to do a more thorough diagnosis.
Can anyone suggest a way to troubleshoot this problem? I did find a DIY on this board to do just that, but it's for the 2.0 engine, which looks completely different to the 2.5 in my car. Is the procedure similar enough that the DIY for the 2.0 will get it done? Is there a way to test the EVAP Purge Valve without replacing it? Where is it, anyway?
Any help would be greatly appreciated. I'm about to sell this car and want/need to get this sorted out first.
