Hi all, I am reaching out here as sort of an urgent cry for help. I have a 2012 tdi passat. 110,000 kilometers, only mods are stage 2 Malone, dsg flash and cold air intake. I drive er hard so I was eventually expecting issues, but these are rather peculiar issues that I don't think I should be having so early, and I have no idea what could be causing them. I've gone to several shops, and most of them had no idea. The only shop that was willing to even look at it is taking it next Friday, but I'm worried the car won't make it.
Issue #1: this is the easiest of the bunch, but I put it here because I'm not sure if it has any connection to issue #2. The engine light is on for a multitude of different codes, all related to the dpf and egr. Things like insufficient flow, something about and sensor and bank 1, dpf regen frequency, etc. I have ordered up a darkside developments delete kit and it will be installed next week
Issue #2: this first came about well after the engine light came on for the dpf. I will do my best to explain it but it is quite tricky to articulate. Basically, when I'm in sport on the highway, around 120 kph, you plant your foot hard and the car hesitates for a few seconds, basically lurches back and forth before it wants to go. Almost feels like the car is choking itself out, and you can hear it in the revs as well, it hesitates and then goes, and hesitates, and goes and then finally gets off smoothly. It has been doing it at various speeds and mostly on the highway. Again, not sure if this is to do with the egr and dpf being problematic or something else. I thought maybe the injectors were gummed up so I filled the tank and added just under 1 full cup of diesel injector cleaner, and then went for a drive. It seems to have helped a bit but hasn't solved the problem. I'm lost.
Issue #3: I don't expect an answer for this one because it's something that would have to be inspected. However, I'm shooting for the moon. I'm gonna post a video under this thread of the sound later today, but basically, when the car is warmed up, if you sit in the driver's seat and leave the door open (because there is so much insulation with the door closed that u wouldn't hear it), I rev it to about 2k and as the revs fall, there's a NASTY rattle from the engine bay. Also a slight rattle under load from somewhere else in the car, but not sure from where and not NEARLY as bad.
Like I said, I am reaching out desperately. If ANYONE has experienced ANY of these issues or knows ANYTHING, PLEASE, I am begging for help, I need the car all weekend long and I don't think it will make it. I want to know if something is critically wrong to the point where I should stop driving and take it in early at another shop. Right now it is certainly still "drive able" but not healthy at all and certainly worrysome to drive. Any help is welcome. Thanks.
