Problem with the brand new Polo Match

[DamnRian]

Your two friends have completely different cars from this point of view. Both diesels. The noise is coming from the engine, and different engines make different noises. The noises their cars' engines make is completely irrelevant.

The noise happens whenever the injector fires. As it's a direct injected petrol engine, the injection of fuel is at a very high pressure and very precisely timed and metered out. As such the injector itself makes quite a bit of noise, as it has to open and close incredibly quickly, and what you're hearing with each 'tick' is the actuator moving back and forth incredibly quickly. In a diesel, there is a similar situation, but the noise is almost always drowned out by the noise of the actual combustion, whereas in a modern direct injected petrol engine the noise isn't always drowned out. It's a completely normal sound for a direct injected engine, especially one in a cheap city car (in the great scheme of things) with comparatively little sound insulation. This is especially the case in an engine like the newer (6c onwards) 1.2 TSI as they are small displacement engines with a cam belt, not a chain, which are naturally very quiet engines.

Right, makes sense. You think I can take it to a mechanic/garage and get some sort of equipment installed to drown the noise?

Doubt it. Although you might want to look and see if there's any under-bonnet insulation? I think the TDIs have some, which isn't fitted to the TSI. Might be worth a try?
