Hi, all. Well, my Check Engine light cam on again yesterday. I have had a HUGE history of that thing going on since 1500 miles (bought the car new). It is always the code that indicates a small leak in the fuel vapor recovery system (the code is always 611 and I think once I had a 612). Now, I had a big TALK with the service manager of my dealership last time the thing went on. He (the service manager) was very accomodating. They did the usual first (change parts like charcoal canister, check valve, rollover valve, even the fuel tank) to no avail. They had VCNA rep preside over the repairs and I talked to him (he was the one who suggested the new fuel tank). After about a month in the shop and about 56 hours of labor logged to the warranty claim I got the car and the problem apperently was "fixed" by installing yet another new chacoal canister (the one they put in evidently was defective). I did not believe this for a moment, but the dealership represented by the service manager handled the matter with examplary tact. They offered me an extended VIP warranty plan on them (on Volvo, really) to appease me. I figured it's worth another try (they replaced all abovementioned parts except the fuel tank before and the longest the light stayed off is a few months). Now about a month and a half after the saga the light came back on. I was infuriated, but not surprised. I decided to get one of those generic OBDII scanners and see if I can reset the light by erasing the codes. I figured that this will let me pass inspection without having to go through the ritualistic warranty claim. Here's where it gets interesting. I bought one of those Actron thingies at AutoZone ($150). Plugged it in. It showed no codes. I then followed the procedure for erasing the codes. Presto! The Check Engine light is no longer on. So, I must assume that the code that caused the light to come on was not one of the generic "mandatory" codes. Now my question is does anyone know how the Volvo codes corelate to the OBDII codes? I have the Volvo pocket bible that has all the specs and codes. I also now have all the codes that the scanner supports. I would like to be able to correlate them. I also would like to know if any mechanics encountered such a stubborn problem with the 611 code on a '98 S70. this is really getting annoying. I know the service department is at a loss, Volvo rep is at a loss, I am certainly at a loss. Not sure what to do.

Please help or just comisurate. I love the car in every other respect and don't want to part with it because of such a stupid and minor problem. the only thing is that my state will fail me for inspection if the check engine light is on.
