Back in July, I had a Borla ATAK cat back installed (the one with the AES simulators). Initially it threw a code because they installed the springs wrong on the active exhaust. That got fixed. A few weeks later, it developed a rattle. It was determined that it was the metal cylinder that the spring connects to was way too loose and that a new design had come out to fix that. I got sent new pipes and solved that problem.
Last week after washing my car, I took it out for a ride and right as I was about to pull in, the check engine light came on. The reader I have was too old to tell me the code but I was able to clear it. It was fine for 5 days and came back. I had someone near me that had a tuner that was at least able to give me a code which was P121b which I'm lead to believe is valve two or the right side. We cleared it again. The light came back 2 days later. I cleared it again and this time started the car and stuck my head under the car to listen for a minute. While the car was doing its warmup, every 20 seconds or so I heard a clicking coming from the active exhaust area as if the actuator was trying to spin but was getting stuck.
I am assuming that something is wrong with the actuator. When it's not cold or raining, which doesn't appear to be anytime soon, I'm gonna jack the car up and take a look but I wanted to see if anyone had any opinions. I'm probably not going to go to the dealership as this will most likely be blamed on the aftermarket exhaust but it seems that I am able to buy the actuators online if that is the problem. The car still runs fine and everything but obviously if the CEL is on, the remote start doesn't work which is a bit of a hassle.
I'm wondering if it's common for the actuator to fail at such an early time (the car has less than 4,000 miles)? Or is it possible that the few times I drove the car when it was really cold (single digits) could have done something?
Thanks for any insight. And by the way, I'm beginning to despise this active exhaust.
