Hi everyone

I have a problem with my 45, I don't know if I'm already oversensitive and that's the way it should be.

such a squeak is heard when adding gas at low revs (groan). always when it gives a little gas and there is a gear change, compartment 1.3-2k.

aso mercedes said it was a turbocharger, I changed, I gave new seals, oils, filter.

it did not work, it is the same as it was ..

the car has 100% power, there are no bugs.

everything's okay?

Not quite the same sound but since you mentioned turbo (completely different cars though)
