In need of some advice plz 👍

14 plate 1.6tdi on 200k been intermittently getting P0401over last 6 weeks or so. Car still runs fine no limp mode or anything but I have had to slightly top up the coolant once or twice too.
Which suggests the cooler I think ?? Noticed abit of residue at bottom of engine around the rubber mount too unfortunately.

Am I right in thinking this engine has 2 EGRs a high and low with cooler ?? Do both have to be replaced??

Where is best to acquire cooler as I dont want to use dealer ??

Any advice greatly appreciated 👍👍

P0401

That is a fault code for the EGR system.
