There is an issue with these 1.6 engines subject to a technical bulletin or two.
Software versions have been updated approximately 10 x now to deal with poor cold starting, poor cold running, egr valve varnishing, DPF regeneration stalls, added injector diagnosis to the software etc.....
Shite engine unfortunately with lots of issues.

What tool are you using to diagnose it with & can you read the engine ECU part number & software version with it?

If so, post up the part number & SW version & i'll let you know if you're on the latest software version & the pitfalls of updating it to the latest version if yours is a few behind.
