2008 (manufactured April 2008) VW Passat 2.0 TSI, automatic, 100k miles.

Newly acquired car that my wife bought for our 16 year old son. Said it didn't have a CEL when she bought it...but now it does!

P119A Fuel Pressure Sensor (G247)
P0171 Fuel Trim; Bank 1


The car seems to drive fine, decent performance for a 17 year old car with 100,000 miles on it. I have checked the crankcase breather (PCV) assembly and it seems to be in working order. I removed it, inspected the diaphragm, conducted a
suck/blow test on it(has suction, but restricts blowing). I sprayed starting fluid/ether around the intake manifold looking for any vacuum leaks, nothing apparent. I also sprayed ether into the transmission inspection port in attempts to check the rear main seal integrity. No change in RPM or idle(there is oil present at the inspection port, but the injection/HPFP pump is leaky so that could be the cause of that oil leak). Fuel pressures seem to be in range according to VCDS readings. From a sticker under the hood, it looks like the timing belt(chain?), water pump and tensioner were replaced in 2021 at 83k miles. Not sure where to start looking next. Any help is appreciated.

Doesn't look like my "code tags" or image URLs are working....I probably goofed them up.

Looks like It's pulling fuel out. So that odd, since it's running lean. I would say to make sure the PCV is the correct part installed. There are 2 different part numbers. One with a check valve and one without. Especially if it look like it was recently replaced. With those miles I would be checking the condition of the timing belt and so on. I would address your oil leak first. This may be why it's running lean. Even though it looks like it's pulling fuel out which would mean its running rich.

Not pictured, but there is a small round orange "check valve" in this PCV setup. I will snag the part number and make sure it goes to this vehicle. I would say this car has several oil leaks and I'm really weighing the option of yanking the whole engine out to do the RMS and all the other "common" leak spots.

Also, TO ANYBODY: How can I "Insert Images" without them being so damn huge in the post?

Would have to resize images manually. RMS i would advise to get a nice aftermarket unit if you plan on holding onto the car for some time. Factory units are total garbage.

Appears to have the current revision of PCV, 06H-103-495-AH.

Didn't they(OEM) revise the RMS?

They did with dual seals that are opposite each other and you need that specialized tool otherwise it will leak like a sieve. Still its a thin rubber seal that glued into a thin alloy housing. I stopped putting in that garbage years ago and now run a aftermarket seal that will never leak. Made by Iabed industries. You still need a tool to install it but it's gonna last a lifetime.

Trying to figure out how to resize images so they don't fill up the entire screen...

That looks like it needs a rear main and everything else. CCTA has a timing chain. Please check cam phase adaption value. It is wise to replace the chain every 100k.

According to the under hood, maintenance sticker the chain was replaced approximately 17,000 miles ago. I will check cam phase adaptation.

Is thee another one that just says cam phase adaption? The spec is anything below -4.0 so at -6.96 you're out of spec. When a timing chain is replaced they usually always settle at 0.0% or slighty over at 0.1.

MVB 93 is the only one that mentions "adaption". Also, I don't have any background knowledge in cam phase adaption...so all of this is pretty Greek to me. I'm gathering from what you said though, that the values I pulled from MVB 93 are saying the chain is out of tolerance? Possibly meaning it didn't actually get replaced, or wasn't replaced correctly?

I would put money on it that it wasnt changed. Water pump maybe, tensioner doubt it because that sticker relates to a timing belt not a chain.
