Over the years I have had a couple of Volkswagen twin charger problems. The first was a new Golf 160 TSI DSG. The car’s first 37,000 miles were problem free, but then I had the dreaded problems requiring an rebuilt engine (waste of time) and a new engine over the course of the next 25,000 miles. It was actually showing the first symptoms again (misfire) when I handed it back to the lease company at 74,000 miles. I then had a new Polo 180 DSG with in which I covered 18,000 miles prior to handing it back when I changed job.

The purpose of this message is to note that the problem free miles were done almost exclusively on Shell V Power. This may be coincidence, but I was wondering if additives in the fuel or the changed ignition timing or amount of fuel (it improved the mpg by 10% on th Polo, less on the Golf) could have had an effect?
