My Audi A3's performance has drastically decreased and there's a loud whistle when I accelerate. I suspect it's the turbocharger. What steps can I take to diagnose and fix the issue?
ReplyThe first step is to check for any visible damage or leakage in the turbocharger. Then, use a boost gauge to measure the boost pressure and compare it with the manufacturer's specifications. It's also important to check the air intake system and the wastegate valve for any issues.
Another common cause of a faulty turbocharger is a clogged or dirty air filter. Make sure to regularly clean or replace it to prevent any performance issues. Additionally, check the oil and oil filter for any debris or metal particles that may indicate a larger issue.
