kindly help! obd error code on 986 2.5L Porsche: toothed belt out of position

[That986]

Without sounding horrible the noise could be a few things (haven't listened to it) and engines shouldn't be making any untoward noises.

Just get it back to the mechanic, slap him hard and ask him to sort it out.

You have a number of good choices as far as Porsche service in Singapore.

The information that you have been posting here does not give any of us the comfort level to believe that they are competent, and you yourself seem to be floundering.

Specifically, which shop has been telling you what you have told us, and where exactly are you located?
