Group - My father drives a 2005 S60 2.5T with 90,000 miles. Last fall with 80K on the clock, he began to notice severe idle hunt at start up, engine acting as if it wants to die. Sometimes the engine does die. He does quite a bit of driving, and has to deal with this several times a day. Soon after it began doing this, it threw a "engine systems service required" message and "check engine" light code, so it was taken to the stealership to be diagnosed. They called him a few hours later & told him it was a bad mass air flow meter, so he authorized them to perform the repairs. After spending half a paycheck, he got it home and the problem quickly returned. The next day, it went back to the stealership. They then called and said they cleaned something (father isn't auto-saavy & can't remember what) and that it was "fixed" <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0"> . So fast-forward to this month. Problem still persists. Fed up with the stealership, he decided to have an independent do the 90K service, thinking all the car needed was a good tune-up. The independent replaced the fuel filter along with the regular spark plugs/air filter, and all the etc. that is called for in the manual. This did not take care of the problem, so this time we had the independent run the code on his computer. Oddly enough, the independent said the mass air flow meter was bad & needed replacement. After informing him that the stealership supposedly already did this last October, we are now wondering if the stealership even replaced the MAF in the first place! To further complicate matters, the independent recently closed his business down and is now working for someone else here in town, so dad is really in a pickle. Any advice would be greatly appreciated. Thanks!
