Hey guys, I have a buddy that purchased an 01 1.8t Auto with 82k miles. He purchased it with a blown turbo and the engine sounding the way it does in this video (he got the car for next to nothing from a family member and is looking to fix and resell it) We have since replaced the turbo with a stock K03 and did the timing belt/water pump $300 ECS kit. We also replaced the Cam chain tensioner in the back of the motor because the lower guide was broken, we thought that was the noise. We put Mobile 1 synthetic 5w30 with the correct amount of oil in the engine. I've seen/heard 1.8t's make this noise if there's too little/too much oil in the engine but we have the perfect amount in there. In the video there's a pretty strong ear piercing sound (try to forget that as it's the air pump to the egr, apparently the pipe is cracked making a high pitched noise) We are not able to figure out what this noise is. When fully warmed up and under load it does smoke, not sure if that's the residual from doing the cam tensioner or not. Oil light is on on the center DIS. I cleared the codes with my VC and restarted the motor and checked again. We are getting one code:
18014 - Rough Road/Engine Torque Signal from ABS: Electrical Malfunction
P1606 - 35-00 - -
I'm not sure if this has anything to do with the motor as I believe he has a faulty ABS control module that needs repair.
Timing on the car is fine, it idles fine, no misfire codes.
