Engine Management Light - VW Golf (Code p26f8)

Hi Guys!
Hope you're all doing well.

I've got a MK7 Golf that unfortunately has just had the EML come on. I've used the OBD2 Scanner to see what it is and have got the following code p26f8. I've checked on Google and it states Coolant Pump but can't find any more info, or whether that info is correct.

Any mechanics around? Or anyone that might have had the same problem before? Any idea what it might potentially be before I go to a garage to get it replaced? Don't want them to do anything unnecessary...

Thanks in advance guys!
