DB9 engine makes a tapping/clunking sound at idle

[TBM850]

Hello all,

With the bonnet up, my 2013 DB9 US left hand drive gives a "clunk" at idle every 8-10 seconds. Sometimes the engine RPM varies slightly afterwards.

Car seems fine. It sounds like something opening and closing rather than engine valve issues.

I have a video but likely too large to upload.

Anyone experience this?

Cheers

Paul

Noticed a similar noise I think on my Rapide the other day. Have you tried it with the A/C turned off? From what I've read the A/C compressor engages with a bit of clunking noise. I turned my A/C off and the noise stopped.

My goodness. Thank you! I will try that. It does sound more like a scheduled "normal" valve or clunk rather than an engine malfunction. Much appreciated. Paul
