Knock or click when starting.

[dlukowsk]

I've got a 2002 V70XC. Today I noticed that when my wife started the car, it made a knock or click sound when the starter was engaged. After the cart starts it is fine. Wondering if anyone has seen this before of have any ideas what is going on before I take it to the shop.

Some side notes:
VIDA shows no codes.

Last week replaced the crankshaft sensor, there were shavings on the sensor, which I was told was normal. (Don't get me started on the stupid copper washer.) Replaced the sensor the code for it went away.

Car has always has hard start problems. I've read, it's probably the fuel rail loosing pressure and I should install a backflow valve to resolve it.

Battery was replaced this summer.

In the video notice the engine shake at the time of the noise.



Thanks for sleuthing.
