Hi Everyone
My A3 2.0 TDI has made the 'dreaded siren noise' since I bought it 2 years ago. It's done 132k and drives great, no smoke, no loss of power etc, just the siren noise. Some people say this is due to a faulty turbo, but others say this is normal and is a result of a poorly designed downpipe bracket that channels the sound of the turbo through the chassis. This is why when people replace their noisy turbos it fixes the problem temporarily but then the nosie comes back as soon as the turbo wears inand starts resonating through the downpipe bracket.
There is supposesdly a revised downpipe bracket available that eliminates the harmonic resonance (turbo siren) noise.
Does anybody have a link to this? I'm not sure what to look for. I would like to try this before replacing the turbo.
Warm regards people,
Jay
