So last Thursday I was on my way home from work cruising down I70W in the left lane about 75MPH (normal routine) when about 2 miles before Clear Spring my Passat went into limp mode and the glow plug light started flashing. I made it to the right shoulder, fearing the worst, and the car stalled as I came to a stop.
After shutting the car off it restarted with no problem. But as I accelerated away as it would go to shift under load it would do the same thing - limp mode with glow plug light flashing. After a couple of times doing this I found that if I put the trans in tip mode I could use 1st and 2nd gears without a problem but when I tried to shift to 3rd it would stumble and go into limp mode.
Using just 1st and 2nd I was able to get off the highway onto US40 and continue, at a reduced rate, on my way home. After going over the mountain west of Clear Spring I was able to coast downhill and pick up some good speed. After coasting and driving it carefully in 1st and 2nd for several miles I found that if I kept the RPM's above 2k I could shift up thru the rest of the gears without a problem. If I went below 2K and tried to shift the engine would stumble and if I wasn't careful go into limp mode again. But I was able to keep my speed up and made it the rest of the way home (40 miles).
I had the car towed into the shop (Sharrett VW in Hagerstown) on Friday. They did a quick code pull but couldn't do anything more. The initial codes pulled were
P0016 - Camshaft Position Sensor / Engine Speed Sensor Incorrect Correlation
P21490 - Fuel Injector Circuit Open
On Tuesday they drove it checked it out some more they found one more code P13D000 which is a Glow Plug Implausible Signal.
So they repaired the car, the timing was off by 1 tooth, so they say, and replaced the #1 glow plug. I picked the car up Tuesday evening and drove it home without any more problems or stumbling.
Hopefully this is the end of it. They said that if it has any more problems there may be a fuel injector going bad - especially if the injector code is thrown again.
