To @Skodaoctoviaestate2008 - Now You may see a little better fuel economy after change this thermostat Not much but if You travel a lot with faulty thermostat with every Kilometer You will lose some Money and it is better to give it for new thermostat

To @WesH - I change mine about a year ago: Click Right Here Disassemble the "Haldex 4"-Pump and clean if necessary this part (I think there is two types of white colored part - but the durt is the same and need to be cleaned):

To @WesH - "Skoda Superb 2" do have "Haldex 4"-Filter.

To @tommygards - I think - it is easy job. There is no difficult and complicated operations. It is about unscrew/screw few bolts and two or three water clamps (here You will need handy and right tools). If you find tutorials - I suggest that half of an hour will be enough :)

To @tommygards - It is not normal. Change the "DSG"-thermostat..

To @Skodaoctoviaestate2008 - Change the "DSG"-Thermostat. This is the "OEM" Part Number: "1K0121113A".

To @ivcars003 - I use "Witson" from few months. It is better than "Erisin" that I use for few weeks.
