Hi, pd160 70kmiles, turbo popped at 63k, replaced with a new turbo - all good but last week, after putting on my air con, I had a high pitch sound as soon as the boost kicks in up until 2k revs, as soon as it hits that, the sound dissappears (I believe). Now I haven't used my air con since (don't think that's the reason) and I still have the noise. There is no power loss to my knowledge, unless there is a slight boost leak? :/, car got serviced the other day and he mentioned a boost pipe was a bit lose, didn't say which but he tightened it back up. Although I still have the noise.
Any ideas? Surely not the turbo going?
Also, car starts at 1k revs, no matter if warm or cold (no faults on system). Car goes back to normal idle (900). But as soon as the engine gets turned off and back on, it goes to 1k, until I drive it for a while again.
Aby ideas?
