2.0 TSI Injector Failure... How Common?

[riversidevw]

On an evening last week, my wife and I were returning home from dining out. The engine in the 2010 Mk6 GTI (with 23K miles) suddenly started shaking badly with a dramatic loss of power accompanied by a lot of exhaust smoke and occasionally strong odor of gasoline. Next morning I checked the oil and sure enough, it reeked of fuel. With difficulty, I restarted the car and crept to the dealership less than a mile away.

The technician told me that injectors 3 and 4 were stuck open. They found faults P087 (low fuel rail pressure) , P0300 (random misfire), P053F (cold start pressure). There were also codes for misfires in cylinders 1, 3, and 4. They replaced all the injectors and seals, changed out the contaminated oil and filter with my GC 0W-30. BTW, the intake valve deposits were reported to be only slight. (Using Shell V-Power).

Surprised the bloody thing functioned at all. I realize there are other reports here of documented or suspected injector woes, but like mine they are isolated anecdotes. Any idea how prevalent these failures might be? I realize that some events are rare and sporadic. Others (like some of the things that afflicted the W8 Passat this car replaced) are more typical of certain designs. Not a lot of fun when this one happens.

I had cylinder 1 show a misfire and the cylinder disabled when I plugged vcds into the car on Monday , I had to get the car towed home on a recovery truck (took16hwaste get home ).
Now the car is sitting in a dealer waiting on a full exhaust system due to petrol going down it (this part is on back order) and getting the faulty injector replaced as well

I just went through this exact same thing, but only on Cylinder 3 (although initially, I had misfires on 1 and 3. Injector on 3 stuck open, flooded the cylinder, caused a ring to unseat and there was lost compression and a valve issue as a result.

Ultimate issue was never really determined. But, in the end, VW replaced the entire head assembly, which, obviously, includes the head gasket, valves, cams, head cover and liquid gasket, oil, coolant, injector, and even the spark plugs since one was fouled and they wanted a matched set of NKGs (I had already replaced the coil hoping that was the issue (apparently, it was on the Cyl 1 misfire). My new dealer is amazing (this is my first experience with them (local dealer is terrible). Definitely worth the drive. Thank goodness for a powertrain warranty. Starting a fund for any future repairs. I'm optimistic, but a bit unnerved.

Car is back in my driveway as of about an hour ago.

49,500 miles by the way.

I just hope I don't need to go through all of the above too get my car back on my driveway . I have told the garage I want them to carry out a pressure test on the cylinders incase of any damaged to the head or block . And got told we will do it if we feel the need for it , but got told from a mate who work in another vw garage too revs the car thought the rev range and check for misfire on vcds and if there any , getting it back into the garage and get it sorted under warranty

My carbon deposits were described as "nothing out of the ordinary." Of course, now, they are nonexistent since the head and its components are new. Good luck, and keep us posted. Hopefully, your situation is not as invasive as mine was ... and is covered under warranty.

Well got the car back last night , the dealer fitted a full exhaust system ,a new injector in cylinder 1 and replaced all the injector's seals aswell as a oil change , was told my a mate to rev the engine all the way through the rew range and watch for a misfire

Same EXACT thing happened to me. VW blamed the tune I have and I paid everything out of pocket. Starting to think it was not the tune. It was cyl 3 on my car as well. Also, just had the coilpack go bad on that very same cyl.
