Our Passat is running well as far as I can tell after the BSM delete, TB, new fan clutch and EGR cooler replacement. In December we drove it AZ to San Antonio and back with zero issues (except needing to add a little oil). 245k-ish miles on it and my wife uses it as a daily driver. She loves it.
However, it's really loud. Like hard to talk to each other standing outside the car with it running. It's like a real airy, whirring sound (yeah, I know, super helpful). It's our 5th TDI so I know the TDI sound...this is on top of that. And I know it will likely be a little louder due to the BSM delete, but how much louder than our 04 Jetta TDI should it be? Maybe it's the spinning chain?
I had a local TDI mechanic slated to come look at it a month and a half ago but he disappeared the day he was supposed to show up. Literally. Phone goes to VM, no response. There's actually a discussion about him in the Arizona forum as nobody can find him and he had a good reputation...was even getting ready to open an independent shop.
After searching the club I don't see any relevant posts about "loud BHW engine". Any suggestions for what would be making the engine sound really loud? Looking for places to start. Sold my VCDS years ago with one of my cars but have another one on the way as of yesterday, so will be able to do more troubleshooting then...just not sure what to even look for now. Again, runs great, gets about 35mpg, just seems really loud. And yes, I did the TB change without VCDS...don't know if timing being slightly off would be relevant to a loud engine.
