Knocking Noise

Recommended Posts

On start up.

Sorry - I'm sure I've read on here before that it's potentially the 12v on the way out, but can't find the thread.

So, usual launch procedure was adhered to - foot on brake, in to D, foot brake off etc. Didn't really notice the knocking noise as the stereo had been left on 'offensive' by the wife. Turned the stereo off and there it was, some strange knocking noise. Not too violent, but loud all the same.

Turned the car off and on again ant it was fine. Got to the office this morning and turned it off and on again and all seems fine. Possibly as a result of the 12v having charged some more?

It's a 2010 TSpirit. I thing Grumpy Cabbie had some engine problem with similar symptoms, but don't recall the diagnosis.

Thanks, chaps.

The car's done 75,000 miles now, so will be excluded from the warranty.

It's a company car so we'll do the work ourselves, however how can the problem be accurately diagnosed? Disassembly?
