Any ideas what's wrong with my Passat?

Hey.

I have a Volkswagen Passat 1.4 TSI petrol. The engine light keeps coming on and there is a rattling in the engine, but four out of five mechanics tell me it's not the timing chain. However, not one knows were the noise is coming from. Faults that keep showing up are camshaft sensor, coils misfiring and fuel sensor. It's keeps losing power.

Any ideas?

Hi Debra,

It’s kind of difficult for us to diagnose a car over the internet unfortunately, but it sounds as if you may have a whole host of problems there. You’re quite right in that rattles are often something to do with either the timing belt or chain or the camshaft mechanism, but if you’re getting multiple fault codes on a diagnostic it could be that there’s a bigger issue that is causing lots of systems to develop issues. Have you brought it to a Volkswagen main dealer yet? That would be our recommended course of action.
