Hello.
I have an issue, as soon as outside tempersture hits 4 degrees Celsius I am getting check engine light and P0403 error code.
Any suggestions how to fix that?

P0403 is an EGR fault. So either remove and clean the EGR valve and see if that works, or replace the EGR valve.

If it's a later model FR170 I would just replace the valve as it's a **** job that you don't want to do twice.

Thank you for the reply. Mine is 2011 model, CFJA engine. So looks like it’s hidden somewhere behind the engine, right? And it looks like one in the photo?

Yep, bad luck. on the 2010 model the EGR was at the front of the engine, 15 minute job to remove/replace.

I'd just buy a new one and replace the old, no point trying to clean it when it's such a pain.

Is it safe to drive if I error comes up intermittently? There is no power loss or anything, just a light on a dash.

Should be fine to drive for now, but eventually it will probably decide to go into limp home mode.

If it starts to do it more often, probably a sign it's about to fail.
