I’m having issues with a coolant leak in 2017 skoda superb sportline 120000miles, the barge have just replaced the charge air cooler but after a week the coolant needed filled again, any suggestions as to the cause 

Which engine? Dsg or Manual?

It’s a manual 2 litre diesel 

I believe on the 2 litre diesel, the air charge cooler is water cooled. So if the leak started after it was changed, I think you need to look there.

Skoda Superb Workshop Manuals are available here

 

Look at the 1.6/2.0 TDI workshop manual pages 212 onward for full details

 

The middle radiator (item 9) is the air charge cooler

Thanks, it had been leaking for a few months and then the charge air cooler was changed about 9 days ago and the coolant is empty again 

There are many areas where the coolant could leak, the charge air electric coolant pump, and heating back up electric pump are candidates for leaks. See p 184 onwards of diesel workshop manual for details.

 

Needs to have the car up on a ramp, remove the undertrays and a detailed inspection in all areas.

The main water pump may be leaking, again visual inspection. Not sure but this may involve removing the timing belt cover.

 

Check main radiator for evidence of leaks.
