Be careful tho with VW roadside assist - especially about anything peculiar to your VW. EG- my missus had the opil light come on a while back and rang the VW roadside assist mob asking about which oil to use. Their answere was "any fully synthetic diesel oil is fine". Great advice.,. unfortunately totally untrue. The TDI has a specific grade of oil (505.01) which MUST be used - if for no other reason Warranty maintainance - not to mention the potential for coking on the pump-deiuce (PD) cam. The specified oil is also NOT fully synthetic.
In other words.. just be careful what they tell you - dont assume they know what they are talking about.
FWIW i still kept my RACQ membership active since purchase (and for that matter even when we purchased our Peugeot 206gti in 2003). WHY? Well for starters, with my 'premium' membership with RACQ, I get more miles for free if i need a tow. That and a couple of other advantages - not to mention keeping my 'years of membership' loyalty stuff.
If you dont have a history with your RAC (etc) , then Id agree with those who say dont bother with having both- just go with the free VW service - unless you do a lot of driving far from home. In other words (I guess) - check what the rules and limits are with VWRA and see how it stacks up against your other membership.
PS. Luckily my better half had taken notice of my obsessive compulsive ramblings about oil prior to the above incident.. and knew that there was more to it than just choosing 'any fully synthetic diesel oil'. She ended up going to the dealership and buying some of the right stuff. Smart cookie she is!
