Slight misfire on cold start - Help

[TEG_DC5_R]

Over the last few days my DC5 has had a slight misfire only on a cold start first thing in the morning.

The EML flashes when this happens but it all clears up after a couple of minutes.

What could be causing this and how could I cure this issue?

All help will be appreciated

Fudged coil pack loose connection, bad earth, dodgy spark plug.

Few things I would try to start with.

Cool! I'll start by looking at them this weekend then

I'd get a reader on it if it was me. Could save you lots of time in the long run. Could be a sensor in the exhaust on its way out or even timing tensioner related in theory but hopefully not. Is your oil level as it should be?

Mark did you say a flashy eml light could be early indication of timing chain/tensioner issue or was that more at high rpms? Was just thinking it takes a while for the tensioner to do its job properly from cold being oil fed

Be worth trying a self fault code test after checking the earths etc.
