VW Passat B6 2.0 FSI BVY Engine: Uneven Idle, EGR Error, Possible 3-Cylinder Operation

Hello, I have a passat b6 with 2.0FSI code BVY 150KM. The car reached me with a non-smoking engine. Vag showed an error with egr ... after disconnecting it, the engine lights up normally and the suction works nicely while when the speed drops, the kennel works as if it were going to 3 cylinders ... on lightly pressed gas about 1300 turns it works perfectly. Currently, the error is from the mentioned EGR because it is disconnected (water got into the valve and everything rotten in it) can the engine go like this because of the disconnected valve? Physically the EGR is closed and tight. In the course of everyone feel nothing, power is.

Unfortunately, I do not know how the car went before the fault ... maybe someone was already driving with such a jerk until he stopped smoking through this egr.

- Compression pressure of 12 bar on each cyl.
- A spark on every candle
- Somebody has already cleaned the valves and carbon deposit
- new pneumothorax tubes
- I used a Pole on the suction manifold in search of leaks and nothing ...


Sometimes an ignition fall out of 1 cyl. I changed places with coils and candles and still falling out of 1cyl. But this error only appears sometimes


Have any ideas ?
Which groups should I log in to fsi?

Buddy, how can you replace or replace the valve of the variable valve timing, I bet that either he fell or some crap is there.
The valve is the one that extends to the right in the ignition coil harness line.

Hi, I suspected you too I even removed the lid from the chain to check if the 3 rings on the adjuster were damaged ... but they are all: / the valve was also dismantled and does not look bad. I will try to do some substitution.

I had a fairy tale in my car and after replacing the valve.

Did you have any mistake? Was the chain heard? Did you buy a drug? How much did you pay?:>

There was a timing synchronization error, I thought something with the chain or timing something was wrong, I had the car in an ASO.
They changed the timing because I already had to check the chain and everything with it and it was perfectly on the locks. Last attempt and they replaced the valve and the car as new. The cost in the valve ASO is PLN 300 as I remember and PLN 100 replacement. You could hear the chain so that the first option even ASO that is something with tensioners or slides and turned out to be a valve.

For me, only error from egr, the chain can not be heard even when firing: / but I will try to replace this valve.

And how is the toy car?

Tomorrow I will replace this stimulus setting. I tested it with Vag when it was dismantled and opened. During the week, I will probably dismantle the entire intake, etc. Suspected injection from 1 cylinder. When I was checking the spark, a large mist of fuel flew from 2,3,4 cylinders when I was turning the starter, and the 1cyl was slightly weaker.

Gentlemen, now I have ignition loss all the time. 1 I changed coils, I replaced candles on this Cyl. and nothing further: /

Swap the gasoline injectors now.

Gentlemen, today I had some time and I dismantled the injectors and valve cover ... I saw such a view: /

I understand that this is the reason for unequal work? the fights are also torn on the boxes ... a bit strange that the engine was running quite quietly etc. The roller from the pusher is rough but not oval, and the cam on 1 cylinder is in better condition than the one in the photo. The photo cam looks very worn, but as if the contact surface with the roller has no level difference with the places where the roller does not touch (golden edges of the cam)

Is this a direct cause of unequal work ?? Why is all this worn down? Oil pressure is supposed to be ... no messages about its absence: / unfortunately I have nothing to measure it physically.

I met with something like this, the engine was rescheduled and previously lay under a cloud. But I've also heard of cases where oil was to blame.

Nothing special in newer VW, especially if someone observed the factory oil change intervals. But that's not the reason. Give these injectors to check.

Pusher from the first cylinder

However, it is round so it probably fulfills its function ...

As for the injections, I already have them on the table and tomorrow I will try to check them by home methods (compressed air with the addition of fuel + 12v to open the coil), maybe you can find out more about their condition you can see that someone has fought hard with this engine: / because everything is stuck with silicone ) lid gasket + silicone, intake manifold gasket + silicone, INJECTIONS stuck onto silicone!

I did such a test, I connected a piece of rubber hose with the injector and I preferred a little bit of WD40 + to it, I connected the compressed air I used about 11v to open the coil each injection, including what was in 1 cyl, spray a nice mist

Short movie.

I changed the injection of 1 out of 4 and the falling out error appeared on 4 cyl. I'm ordering an injector and I'll see what happens.

Gentlemen, I replaced the injector with another one that is working properly and no error from the ignition loss occurs even after a long ride but still jerks the engine like in the video. The only error that pops up from time to time is the probe 3 ... I will add that Passat is with the machine and it is uneven only on the P and N positions, if you throw it in "D" or anything that lightly loads the engine, you can hardly feel the vibrations. ..: / today I was putting the valve of the timing and EGR control valve in working order and 0 results: / where else to look?

Toy car repaired! It's perfect it didn't leave me alone I dismantled the fights, the chain and played a variator out of curiosity to see how it looks inside it turned out that there is something like a washer with a notch and a spring for me, the washer was wiped practically evenly and wedged in the hole in which it should work loosely (I compared the appearance of the center with the film on youtube) I bought a damaged variator, translated the washer and the engine works perfectly additionally, I cleaned the strainer which is between the head and the timing chain housing

Comparison of washers

Hello,
A great solution to the problem. I already bought a second car occasionally with the same symptom and no one knew what it was, and in both cases it was the same. One car is a Passat 2.0 FSI and the other is an Audi A6 TFSI. In both cases there are no errors in the computer. In the Audi, the car additionally kicked when firing. I will add a few of my comments. The key to unscrew the ZFR wheel is 10mm RIBE looks similar to the Torx, but you will not unscrew it. The screw is glued to the glue, so it is worth to heat it up and one quick move if not, it remains to drill (the screw is 12mm). When replacing the ZFR, always put in new rings 06F198107A but not those with all ... o because there they sell plastic crap that does not work because there is no gap on the perimeter, so when pressing, you will either break them or cut them short. Only original steel rings that have a gap of about 3mm on the circumference and compress when inserted. Every time I do this job, I replace the chain, the tensioner and, of course, the seal. In one of the openings from the housing there is a small filter that you should remove and clean.
Tighten the ZFR screw by 20NM and add 45 degrees. Timing cover bolts 10Nm. A lock would be useful to set the shafts, but I did without it and it will also work with an 18mm wrench to move the fight and a morsel to lock. I hope to help someone.
