    I have had this problem on my TDi, turned out to be a loose (and / or dirty) electrical connection to one of the injectors

Find the bad sparkplug or wire; or miswired plugs; or distributor foolishness (carbon buildup, dirt, cracked component in there at bottom....)  Maybe there's a leak or sediment in the F/I vacuum tee someplace that would cause funky load artifacts like that misfire, if the plugs all look honest.

Car is sluggish and shakes when gets up to 50 mph


sounds like engine misfire to me. but it takes a mech, driving to tell.
if engine misfires?
try getting a 60k mile full tune up.
open glove box, see opr guide? see service list, see 60k column (it repeats)
bingo.?
filters (air/fuel), fluids, spark parts. (generic list, RTM)
or login to alldata.com and click maintenance then full chart
then see all things in the 60k column, those.

My 1997 passat keeps Losing power above the speed off 50 mph. Its like it trips out and it has about 30 hp and you cant hear the turbo. can you please help?


whats the condition of the sparkplugs,airfilter,throttle body and does the maf(sensor on the airbox) work as they do go faulty.Depending on mileage of the engine, the catalytic converter breaks up inside blocking the exhaust gasses and can cause this fault,listen for rattling from the cat or tap it lightly when cold with your habd to hear but dont use anything else as you can damage a good unit.

It sounds more like a cable or linkage sticking, and yes it is transmission related, sort of, just because of the high RPM before shifting. Spray all your cables good with lube, at throttle linkage, and get under and look where cable & linkages are at side of transmission, and spray them good too, and work them back & forth, to try & loosen them up. Truck shut off & in park when under it eh.!
Then work shifter back & forth, gas pedal to floor & up etc, to try & loosen things up. That may just cure your problem.
