Turbo failed without warning on the highway and I was unable to maintain the speed limit. This occurred in a vehicle that had the tdi emissions modification. The problem occurred a second time after a warranty repair at vic bailey Volkswagen and appears to be an ongoing problem that is related to the emissions modification. The first failure occurred approximately 20,000 miles after the emissions modification, and only 1300 miles after the previous failure and replacement of the turbo.

The vehicle has a hard time on startup when stationary (when the temperature fluctuates from freezing to thawing), sometimes taking three to four times for it to crank over. Once it cranks over it will vibrate and shake like it is going to stall. It will also shake and act like it's going to stall after in motion for the first minute. Took to the dealership, said it was an old battery. Replaced battery, the issue is intermittent (again when the temperature fluctuates). Read online that it could be a tdi intercooler design flaw. The dealership will not cover unless they experience the problem. This issue says it can cause engine failure. Looking to take it to an independent VW tdi shop to see if they can diagnose the problem and get a second opinion. Hopefully, this doesn't have anything to do with the fuel pump.
