Car occasionally taking a long time to start.

[Owen92]

I've got a mk3 Clio 1.2 that's on 7000miles. Occasionally it will take a while to start, sometimes it will start straight away. I've tested the battery with a Midtronics battery tester and the result came back as a good battery.
Any ideas what is causing this?

Crank sensor maybe?

It will turn over every time, but will take a long time to fire on some occasions. The speed it turns over is normal, which rules out the battery or the starter motor.

It's under warranty, as it's less that a year old, but don't fancy taking it in when it's only an intermittent fault.

TDC sensor.

Take it into Renault, that's what warranty is designed for!

I took mine back for them to sort out a clip on a piece of dash trim!

If you've paid for a new car it's one of the privileges

It will end up going back to Renault at some point. Just wanted to see if someone knew what it was because it annoys me not being able to work it out.
