Hey guys, I got a 180 fwd TT with revo chip. I was just driving along this morning and when I tried to accelerate, I didnt have as much power as I should have. I can't hear my turbo working so I dont think it's a vac leak or anything, it's just not engaging. I don't know if it could be in limp mode or something since I dont know much about that, but I have been using the revo tune for a while. Any help would be appreciated, thanks.

 

if you dont have a boost gauge, there isnt much any of us can do. You can only go look for loose connections

 

limp mode will only make about 5psi of boost, you can try disconnecting the battery for a few minutes to clear the code if thats the case, and when you start it again, hopefully you'll be back to full power, otherwise, theres nothing we can do w/o more info.

 

Well i got a CEL code and cleared it, and then my turbo was working fine for 3-4 days until my turbo stopped again. This time, the CEL turned on at the same time that my turbo stopped working. I got the code P1128 Long Term Fuel Trim Mult., Bank1 System Too Lean.

 

Its either a vac leak or the precat o2 sensor is bad. Since it was good and then bad again, i would lean towards the o2

 

OK, is there anyway i can check the o2 sensor with vagcom? And also how hard would it be for me to change it myself? Easy or should i just take it in to a shop?

 

Changing them isnt to hard, just kind of annoying. You have the code, could rule out a vac leak if you would of got a boost gauge like all turbo cars should have
