Volkswagen Golf 2006 1.9L Tdi 105 137000 km
Hi,
I drive a 2006 Volkswagen Golf 1.9 TDI with around 220,000 km.
Recently, I noticed two issues:
1. A blowing or whistling sound when accelerating and decelerating, which seems to come from underneath the car, possibly around the exhaust line or turbo.
2. A metallic rattling or ticking noise, especially noticeable at low RPMs.
Both noises are more noticeable when the engine is cold, but sometimes persist when hot. I haven’t experienced any significant power loss, and nothing shows up on the diagnostic scan (OBD/valise).
Could this be due to a leak in the exhaust system, a loose or damaged hose, turbo issues, or maybe injectors or valve lifters?
Thanks in advance for your help or similar experiences!
