Hi everyone, P307 1.6 16V petrol, when i lift foot of acc pedal i hear some squeak coming from engine bay. When i roll car in place i can’t hear it, it’s pissing me off so i started looking for problems. Local mechanic said it’s nothing dramatic as engine mounts are all ok. He said that metal which is preventing gearbox from engine heat might make those sound but i shouldn’t remove it. Any ideas/solutions to this?
