This is hopefully the last time I post on the CEL issue on my 360. Okay maybe I am speaking too soon, but hey knock on wood. Scottdale Ferrari (SF) has taken the car in (by trailer this time). It was a bit of a hassle getting it on a trailer bec there was no hole in the front grill for the tow hook. SF suggested poking a hole into the grill and they would fix/replace it later. The tow truck driver and I both opted for using chains instead. I am not sure it SF will end up fixing this or we are just using chains again on the transport back. Lesson #1: not all 360s have holes in the front grill. If you do not you can poke a hole or you can use chains. Next, they put my old cats on a used Ferrari. There were no problems. So rule out cats. Lesson #2: its a good idea to verify what you think failed really failed. Now, two weeks into the service (not including a week where I took the car out), they think they have pinpointed the real culprit: the mass airflow sensors. Putting my sensors on a used Ferrari caused the other Ferrari to start behaving erratically (in terms of codes). Lesson #3: Mass Airflow Sensors can cause a cat code to be thrown! If all goes well I will get my car back tomorrow. That would be several hundred miles put on the car and 2 weeks later. But I will finally have a car to drive again. And it will work. Just as an amusing anecdote. Things got pretty nasty at SF when I confronted the manager for the first time on the car issue. I wanted to trade out for a newer car and pay half the difference. I was turned down and lets just say I wasn't treated quite as politely as you would expect from oh say a Chevy dealership. I suspect they thought I was trying to screw with them. When all I wanted was to make a good deal that would benefit both parties. Anyway thats history now, the reason I brought that up was that the manager told me to take my car back and swore on his mothers grave that if the CEL came back on, he'd gladly pay $75000 as a guarantee (he said he was THAT confident the CEL was taken care of). I was halfway tempted to tell him thats how much he owes me now. But since SF decided to keep things civil from that point on, I'll do the same. Lesson #4 (for dealers): be nice to your customers.
