Had my Cupra TDi just over a year now, covered 10k with minimal reliability issues
Car is equipped with a Miltek Sport exhaust and De-Cat. The usual "police siren" like noise has been present since I bought the car, spooling and De spooling of the turbo.
However on a cold start the pitch of that "police like siren" has changed somewhat. A high pitched sort of scream like whine occurs for the first 30 seconds of driving. Also, and this is what made my wonder if it's a sticking veins issues, there's hardly any boost when this odd noise appears.
When the engine has been running a few minutes and turbo has been engaged a few times the noise disappears.
My local garage advises me there's a type of cleaning kit for these particular turbos and that it may rectify the problem.
Anybody else experienced this kind of issue?
All comments appreciated
