A Moving Billboard

So, less than a month ago, we purchased a 2009 VW Routan. So far, I have loved it! Until today....a friend and I were coming back from our neighboring town and all of a sudden I noticed the RPMs were high and I couldn't get the van to go over 40mph. After a phone call to the dealership, the service manager told me it had gone into "limp home" mode which prevents me from doing more harm to the engine by keeping it at a low rate of speed. They asked me to drive it in to the dealership. Mind you I was 15 miles from home, had to take my friend home b/c it was close to when school got out and needed to pick up our kids, then drive another 30+ miles to the dealership...at 30 mph....all on back roads. I was NOT thrilled. Fortunately, my husband was able to meet me and we switched vehicles and he drove the rest of the way to the dealership. They were able to fix the problem but wanted to keep it to figure out why it happened in the first place. So, now, I am driving a "moving billboard". Tomorrow our kids have soccer and then my daughter and I have to drive 2 hours north in order to host a shower for my nephew's wife-to-be. So, I will be driving a white passat plastered with Volkswagon of CR and websites and phone numbers all over the car. I guess I should be grateful that I have something to drive, but I will be a little embarassed.
