Thanks guys, sounds like I need that part replaced then. Am I right in thinking this is the part I need for a 2013 Superb Mk2 Elegance CRTDI A:

2.0 TDI CR 125kW/170PS CFGB 05/2010 → 05/2015 ?

 

Thanks again for helping an ignorant lurker!

@Fishlex

About £20 to buy from an Autoparts dealer or ABOUT £10 dearer from the dealer

From Autodoc

Sorry for the late update but I am a lazy man and it's taken me this long to get the part and get it fitted. The problem is completely solved thanks to all of you! I bought the part listed above for about £25 and my local garage fitted it for £42. Started the car up at the garage and by the time I'd driven the five minutes home the engine was up to 79. I can normally drive it on the motorway for 40 mins and just hit 70 so I'm a very happy man, especially now the cold weather is here.

 

Thanks again to all of you.

How easy is this part to fit? Easy enough to do myself? I think mine has this problem, town driving it'll get to 90 degrees everntually, but even a 20 mile motorway blast at motorway speeds won't get the temp to 90.

Could you possibly link me to it? I may be being blind but I can not find it. 
 

No garages near me will do it for some reason! Only main dealer.

Literally every garage has no idea what I'm talking about.

To " @Alan16ac " - For "Superb" and "Yety" it is the same: Click Right Here.

Thanks, it looks like something I'd prefer a professional to do. But so many so called VAG specialists have no idea what I'm talking about. 😞

To " @Alan16ac " - It is like the "Haldex 4" Filter for "4x4" Cars The filter is definitely there but Official "Skoda" Services does not know that Fact..

So even my local Skoda dealers won't so it now, without first diagnosing that it is that that's the problem, which of course they want to charge for the pleasure of doing. Looks like I'll have to do it myself.

To " @Alan16ac " - You can have only one Problem. The rubber hose-pipe can be stuck to "DSG"-Thermostat because of many years. You need to push something slim and without sharp edges but hard enough to peel off the hose-pipe of the "DSG"-Thermostat. Do not use hard power. Millimeter by Millimeter, slowly, you will peel off the sticky hose-pipe. Any other things, that you need to do, are easy and there is nothing you can do wrong.

@Alan16ac

Its an easy job especially with the proper tool well worth £11 delivered next day 
See my link above for the part from Amazon as well

Take of the Thermostat complete with the 2 rubber pipes still attached to it 

Its easier that way then you can mark the orientation of the pipes with tipex to get the correct angle to refit 

Hardest bit is removing the airbox pipes 

Dont worry about the spillage of coolant as you loose hardly any when replacing 

Just top up with the correct coolant at finish

Well thank you Briskoda and its members. £19 part from amazon and my car is sitting at 90 again! The thermostat was fitted today and has cured my problem. The cabin is so much warmer now too. 😄

Like many on this thread I had the same problem on my Superb II 4x4 TDI - taking miles and miles to warm up and then cooling down when going downhill.

My nearest main dealer diagnosed the main thermostat, but when it was changed there was little difference. Like most main dealers they charge for a consultation which proved to be a waste of time.

 

Thanks to this forum I explained to my usual independent garage what the problem was, gave them to part number and asked them to change the DSG thermostat.
They called up a picture of the cooling system on their database and identified where the part was and acknowledged that I was not going insane!

 

3/4 hrs labour later and all is now well.

 

 

Thanks everyone!

99% certain it's the DSG thermostat. Mine was behaving exactly like yours. Changed the DSG thermostat, and the problem was gone.

Now heats up to 90 degrees and stays there.

 

Parts and cost here in the UK were:

1K0 121 087 AH - Splitter with filter - £9.17 

1K0 121 113 A - DSG Thermostat - £27.55 

 

The splitter with filter probably won't need doing, depending on the age of your car.

From what I'm told, earlier versions of the splitter didn't have a metal gauze filter in them, which could result in contamination getting into the thermostat and hence causing premature failure.

My car (2012 MY) had the filter when examined, so I didn't bother to change the part. If you do decide to change it, you'll need new hose clamps, as the ones on the car are single use.

 

Hi,

New on this forum and checking out the same problem and amazingly it has sorted out. Thanks Bagpuss for suggesting DSG Thermostat. I just went to the garage and asked him to change this part only. Now its perfect and hitting 90 dig. Love this forum
