Towing with Skoda 2L diesel

Not come across this before and there are plenty of people on here towing with various VW Group cars with that engine, me included. Do any of the Skoda or VW forums shed any light on this - or a solution? Lats summer we were towing into Europe with ambient temperatures in the high 30's and the coolant temperature rose on some long uphill autobahn sections, however it also rapidly dropped when going down hill again. 

Do you know which oil is being used? Without going into nerdy detail VAG do have different specifications and viscosities which could be used in that engine - one is 5/30 and one is 5/40. The thicker 5/40 will be a better oil to use for towing/motorway work etc, the 5/30 better for short distances, quicker warm up. 

Reducing the speed hills are climbed will reduce the power needed and with it the engine oil temperatures reached.

As generally will holding lower gears so the power is developed at lower torque, so lower piston temperatures, improved scavenging cooling, better piston oil cooling and better heat dissipation.

I am surprised that the oil company grab to panic with a temperature of 125 C, it is quite high but should be for [hopefully] a synthetic well below oil oxidation temperatures; I worked some military units up to 140 C knowing it was just an encounter and not held for long; that really does eat into oil life.

In your case knowing things get hot on a long uphill drag I would simply ease off a little and use more revs for the few periods it is encountered. If worried still, then change the engine oil more regularly and whatever you do buy high quality oils.

Domestic cars are not primarily designed for the massive overloads of towing caravans; if using them for that we need to be sympathetic to the extra stresses it causes.

Of course there may be a remote chance the oil temp sensor is a bit 'iffy', for the cost of a replacement perhaps change it! Or even re-calibration of the existing one needs to be done.

I have a Skoda Octavia Estate 2.0TDi 4x4 (2012) I did tow 1,230kg (now towing 1,318kg), never had any problem at all even when outside temp has been 30c on German / Czech motorways and on some long hills. I am on a 2 year / 20,000 mile service using oil to VW 507 00 spec. Cannot find any reference to oil temp in my handbook

I have a Yeti 2.0L 109BHP, 110k Miles. I always have raised oil temp when towing, but around 110degrees is the max I have seen, usually less. I change oil/filter every 10k and use Eurocarparts Triple QX 5w-30 VAG. I used what I thought was a "better" oil last year, and found rattles and poorer performance??? I do 30k per year so oil change is regular for me! Have you tried a flushing oil?

I cannot find any other reference to suggest this is a common fault. There is an oil pump problem with earlier versions of this engine but nothing about raised oil temperature.

Could you repeat that please, didn't quite catch it.
