  • $300 later and the G8 is fixed

    Cutting to the chase… when I installed my Volant CAI I started a chain reaction that resulted in where I am today.

    The problem ended-up being a damaged wire harness leading to the Mass Air Flow (MAF) sensor. The wire was damaged when it came in contact with a pulley on the front of the engine. The resulting damage caused a short and damaged the fuse block. The second time the car died the fuse block wasn’t damaged, but the PCM (ECM?) went into a fail-safe mode (not letting the car restart).

    To fix things the damaged harness was repaired and the PCM was re-programmed. The new harness is shorter and is being routed in a different position such that it will not contact the pulley.

    So the problem is solved, but it wasn’t (really) covered under warranty. What am I talking about? Well, the car is covered under warranty, but only against factory issues. Installing after-market equipment (like the cold air intake) starts to get into the gray areas of warranties. Because the damage was caused due to the install of the CAI, it wasn’t covered… but the dealership worked with me and only charged me for the parts that were replaced ($300).

    I tested out the car in the acceleration department on the way home and there is definitely a stock tune in the ECM. I haven’t been able to determine if the TCM was re-programmed as well. I would tune the ECM again, but (thinking they were being nice) the dealer filled-up the car with half-a-tank of 87 octane (Yuck!). Looks like I’ll have to burn-off what is in the tank before I can get things back the way I really want them.

    In the end, I’m actually kinda glad that there was something that was fixed. When they first said that it was ‘just the fuse block’ and that everything would be OK… I still had some doubts that everything was going to be OK. Knowing that there was something broken (the MAF sensor harness) that was repaired gives me greater confidence that there will not be a problem in the future.
