Question about Volvo Pro connection guarantee

Hello, since I have the first test with my Volvo (see Fred Kupplung pulls air) I have dealt with the topic of connection guarantee. The services of the Volvo Pro connection guarantee are shown on the HP. 12 months for 118 Euro 24 Mon for 273 Euro 36 Mon for 356 Euro. Since I have a gas system in it there is only a 50% surcharge: 12 Mon 178 Euro 24 Mon 410 Euro 36 Mon 534 Euro. Do you think the Volvo Pro is useful? Of course none of you can say what is going to be broken or not, but a certain amount of “sciherity” is it, right? The restrictions on luf performance are known to me (Lohnkosten are always paid 100%). Are there any other relevant restrictions. Especially with regard to the gas system and the corresponding warranty on the engine I would now tend to the direction: yes to the connection guarantee. Oh yes: factory guarantee runs until March 2011 and I have currently 40tkm on the clock. Pope
