When starting there is sometimes a grinding noise for a few seconds then goes away. This sometimes cuts the engine out - 05 scenic

hydraulic tappets ?
if the noise goes away.... thats normal

if the noise didnt go away - then that would need looking into

Sounds like the battery has low charge or is defective. The clicking is the starter solenoid, which commonly happens with low voltage.

Sounds like excess bearing clearance, when the engine sits overnight the oil between the bearings and the crankshaft is able to run back into the oil pan. When you first start it up it takes a few seconds for the oil pump to fill the spaces back up and you get some clatter.

Upload video please then i might have a better idea

Sounds like something with bad bearings. Check in the area of air conditioner compressor or power steering and yes water pump.even the belt tightener will do that.

There are multiple possibilities causing such problem.Click the link below:---

From what your saying it sounds like your fly wheel .or your starter's sylinoid may have some broken theeth.chech it out.

bad bearing in pulleys need to be replaced

The cylinder head gaskit is on it's way out! had this before! caused by water leeking into the cylider(s) and making the compresion come right up ! remember air /fuel mixture is compressable water is NOT!

Could be a starter sticking but that would cause more of a grinding noise, my best guess is that your flex-plate(flywheel) is broken if the noise is coming from between the engine and transmission. Remove the access cover for the bell housing and take a look at the flex-plate.
