[Recall on diesel cooling issue?]

I took to a longer route on a motorway yesterday and surprisingly the car’s temperature went down for a while on the motorway and then raised back to 90 after a short while . Please see the picture. Could this mean one could have issues in winters on motorway driving ?? Let’s wait and see 

PS: I was in the passenger seat before anyone points out taking photos while driving 😛

Took it to the motorway and no heating issues whatsoever. Seems like the hack worked ! Thanks guys. Also contacted VW and they said there’s no recall on the  Polos from their end for the water pump but there’s a recall for the fuel pump and some reprogramming .

Fingers crossed 🤞🏼 let’s see if the hack works

Similar issue with the Polo 1.4 TDi Bluemotion. Car has only 18K on the clock and it’s a late 2014 model. They have the same engines at the Fabia MK111. 1.4 TDi CUSB 90 BHp I have disconnected the solenoid plug. This is how it look .
