Right guys i have a feeling i may be down on power.
My S3 is almost 5 years old. I ve heard replacing the DV can restore power if faulty ? it being 5 years is it fair to say its been used would this have a wear & tear affect on it ?. Also is there an alternative replacement which will perform better ?.
I ve considered replacing the N75 valve for a J type i ve heard larger boost is capable would this work on a standard bam engine ? how much do these cost ?
As far as i m aware there is fault codes, the turbo does have a high pitch which i ve read means theres a leak in the system or something else is wrong.
Any advice would be great.
