i have a 2000 a4 1.8t and i had the ko4 on my car for 2 months then it all of a sudden started burning oil and smoke started comming out of my exhust....now it was still holding good boost but i had to take it off cause i didnt want it to mess the engine up....when i took the turbo back off one of the turbine (or what ever you call the fan looking thing in the middle of the turbo) was loose....does anyone know what could be wrong with my ko4 or does anyone know where i can take it to get fixed because awe wouldnt help me out cause i waited too long and the 90 day warrenty was not in effect.....thanks for the help.

 

Sounds like the turbo is toast. The turbine should not be wobbling. Leaving it in the car will likely lead to a nice big boom which could eat your motor.

May either be a dud, or it did not have an adequate oil supply. If it is under warranty, get it replaced now. Before installing the next new one, be sure to inspect the oil feed lines, as the #1 reason for early turbo failure is lack of lubrication due to bad or clogged lines. Also, be sure not to shut off the car immediately after a hard run...drive it for a few minutes easily, or let it idle down and cool off. Glowing hot turbo + switching off immediately will cook the oil in the turbo and cause premature failure.

Cheers,

Steve

 

i dont have warrenty...but the people at awe said that it would be cheaper and possible to get it fixed than buy a new one for 1000$....and yes i always let it sit as if i had a turbo timer.....btw does anyone know anybody with a ko4 for sale ?

 

or does anyone know where to get one less that 1000$

 

mrhurst, check www.google.com, I hear that's a fantastic source for everything you could possibly need.

(No offense intended with that ******** reply)

 

your real cool justr like all the others....i wouldnt post the questions if i could find it on google because i know that alot of people are a$$holes about that on here. thanks for the help!!

 

sorry but he has a point. a quick use of the search function would turn up quite a few k04 threads and 'my turbo exploded' threads. a new k04 runs about $750 from most web sites. search for "turbo shaft play" that will give you some more info on what happened. there are turbo rebuild kits available but sometimes if you damage it too much (bent shaft) theres no repairing it. you also want it balanced after doing the repair, which is not something you can do youself.
