Angry Snow flap recall

Umm. This will drastically effect your fuel economy. Even though the service tech and the manager both swore it would not. I used to love my TDI that got 46 mpg. Now I have an overpriced piece of junk that barely gets 29 mpg. The only difference, one stupid recall. Just say no.

LOL, you guys kill me. Seriously, if any 4 cyl TDI was getting 29 MPG you'd have a constant black cloud following you around. There simply isn't any way the engine could consume that much fuel. Or you have a fuel leak.

Brian is absolutely right. My dealer many years ago tried to sell me a set of tires that had a load rating of 89 when my B5.5 at the time needed a load rating of 91.

I told him, ah no. Went to my favorite tire vendor, who is a about 8 blocks from my house and he got me what was required. I really believe that some do not understand the load rating system. Do not forget that if you get into an accident and it is considered your fault and they find your tires are not the right load rating, that could get you into trouble.

Unhappy Mileage

I have recently gone from a 2013 TDI SE manual transmission that was averaging 43 mpg city and highway combined to a 2015 "fixed" TDI SEL Premium that is getting approximately 33 mpg city and highway combined; a 25% drop in mpg. This is much worse mileage than I expected since much of the information out there including from VW is there may be nothing to about a 12% loss of mpg as a result of the "fix". The 2015 has about 30,000 miles. My 2013 which I was planning on doing the buyback has 75,000 miles. Can anybody offer any encouragement to me for possible improving the mpg on the 2015? Are there others that are experiencing this low of mpg on their fixed 2015 TDI SELs? It's really been affecting my sleep.

So could this be why I'm only getting a mere 33 mpg city and highway combined with my "fixed" 2015 TDI Passat SEL DSG? I doubt that it will even meet the 30 city 42 highway EPA ratings.
