Hi, I have a 2006 Volvo S60. Here is the story, Saturday evening, the check engine light came on. Sunday, we went to the dealer to check it out and for 60k service. the dealer said they scanned the code. The fault code is inactive, it is related to Fuel Pressure. They checked the fuel pressure. No problem there. So, the tech just reset the light. We took the car home. Then, Monday morning, go to work, everything was fine. Then, in the afternoon, the light came on again. So, tuesday, went to the dealer again. They scanned again, they found two issues, 1, code, A12B, 2, BCM 0100, so, they replaced fuel pump module, and abs control module. both are expensive. Then, we went to pick up the car. before we left the parking lot, the check engine light came on again. So, we talked to the service guy, that inactive code is there again. the guy said, it is inactive code, the car is working 100%, no problem. but we left the car at the dealer, they will check it again. I forgot to write down the fault code, but it is still related to fuel pressure.

so, anyone knows what is going on? If the car is working, i don't want to see that Check Engine light on.

thanks

I had a similar issue recently. The code was inactive after the dealer here in Korea called somewhere in Europe they found that my car which is a U.S. spec vehicle has a very sensitive ERC Pump (Carbon pump). I had it replaced and no check engine light in three weeks. Hope this helps.

 

my code is reading large evap leak...and i have replaced the gas cap but it still won't go away so i am searching the VADIS for help. I have a hard time trusting people about my car. No one around where I live even drives Volvo's.

 

Karrilee, you've may a cracked or disconnected EVAP hose in the engine bay. If you can find the EVAP test port or the EVAP canister (I don't know where either are off hand), you might be able to track down the leak. The test port should be a small tee off of a 1/2" (or so) diameter hose. It may have a green cap on it. Once you find the EVAP canister or test port, trace the hoses back to their origins and look for cracks or breaks along the way. If you find one, repair it by splicing in a new piece of hose and you should be back in business. The VADIS software should help you locate the EVAP parts.

Sorry, I have no help for the OP.

 

I talked to the dealer today. They will get the foreman to take a look. I also got the fault code, it is ECM 2900,Fuel pressure control valve Signal too high. but they checked the fuel pressure. no problem. Was this the code you had?

thanks
