hi, my 2000 audi a4 1.8t turbo was burning some oil, last Saturday/Sunday open the turbine and put the turbo repair kit, change the turbo exhaust for a stainless steel tube turbo exhaust. the problem is that i could not use the front oxygen sensor cause the postition of the sensor and the new turbo exhaust just does not fit, place a bolt instead the sensor. the car is running great without cel codes, can I do that with the sensor or i need to relocate the sensor??? what is the use of that sensor???thanks
billy

the front oxygen sensor determines the fuel air mixture.

upsss!!! is going back today!!!...thanks...
