Just had my car mapped at R-Tech & a potential issue has been found. When accelerating hard a squeak comes from the engine bay. I've noticed this before but didn't realise it was an issue. My twintake was removed and this exaggerated the noise. The PCV has been replaced to.
Does anybody have any idea what it may be or how to fix it?
I'm worried it may be the turbo, which apparently has quite a bit of oil around it. Hopefully it's nothing major.
