Johan, welcome!
If I can remember correctly the specs of your car would allow you to tow the van. I do not know the van, best is to check the weight of the van and see if you will be towing legally.
Don't have the stats anymore, but I was looking for a Cross Polo 1.9tdi to tow my Sprite Swing and can remember that the torque was more than enough to do the job.
By trafic regulations the Gross Vehicle Mass(GVM) of the Caravan may not exceed the Tara weight listed on the license disk of the tow vehicle. This however is difficult for the authorities to enforce, because of reasons I am not going to bore you with now.
What the traffic authorities do use at a weighbridge is the actual specifications of the vehicle as supplied by the manufacturer. This is the weight specified by the manufacturer that the vehicle may tow. To determine that, you need to find the information plate/sticker either in the enjin compartment or in one of the doors. On this plate/sticker the Gross Combined Mass(GCM), Gross Vehicle Mass(GVM), Front Axle Load and Rear Axle load is displayed.
All you need to do is subtract the GVM from the GCM and that will tell you what the vehicle is capable of towing.
Remember that it is not only the enjin power that determine if a vehicle can tow a trailer but the weight limitations as provided by the manufacturer are the biggest factor. Due to the fact that very small cars have diesel enjins with turbos and so on providing more than enough power to tow a caravan but its the weight isue that makes a combination relatively stable or not.
