Yes there are:

 - Early 05 Manual GTI, 1 additional inline thermostat
 - Early 05 DSG GTI, 2 additional inline thermostats
 - Late 05 onwards Manual GTI, no additional inline thermostat
 - Late 05 onwards, DSG GTI, 1 additional inline thermostat

Hope this helps!

OEM+ 2005 GTI DSG (high factory standard spec and upgraded with S3 alloy hubs, S3 alloy wishbones, Bilstein B8s and VWR springs by my own hands) owned since 2008 and still loving it!

I replaced my main one which brings me up to 90 but it takes 20 - 30 mins to get there leading me to believe my inline one is gone.

I have a manual.

I don't suppose you know the part number for the inline one on the manual?

Just to complicate numbers a bit - I have a 55 plate DSG and there is only 1 inline thermostat on mine!
However, changing it was not too difficult and really speeded up the warm up - 2-3 miles to 90 instead of 5-6miles. Great in winter!

Do you think the inline thermo is in the same spot on manual and dsg?

I reckon I'll have a bash at mine. You wouldn't have a part number to hand?

I believe it is in the same place. R/H side of engine block, below the battery level. Its black, cylindrical and about 4"/100mm long.
The part number - and I believe they are all the same - 4EO 121 113.
