Hello,
'For the past few days, I've been experiencing engine misfires. Then it starts emitting blue smoke and the car smells terrible.'
Data: Passat 3C, manual transmission (BMP), 120,000 km mileage, new dual-mass flywheel (ZMS), new tandem pump, new EGR valve, variable valve lift (VVP) replaced one year ago, new exhaust system from the catalytic converter.
'The data is all fine (as long as the engine is running smoothly). Every time I read the data with VCDS, the car was working perfectly.'
Does anyone have any ideas?
My suspicion is that a nozzle has an electrical problem - which isn't visible when taking measurements.
Thank you, and if anyone has had a similar request before, please provide a link to it.
Best regards from Oldenburg, Lower Saxony. icon_biggrin.gif

The scan is coming. I'm currently on vacation.
Now, even the indicator light was blinking, and the emergency program has been activated.
I think the particulate filter is clogged. It has 320,000 km on it!
When I'm back home on Sunday, I will read aloud.
Best regards,

Perhaps the flux capacitor has a loose connection...?

"First, get the data organized and run the auto-scan, then we can proceed. It seems like you're on vacation far away if you're racking up 200,000 km so quickly. If that was the easy part, there will definitely be a few more tasks for VCDS on the way back, and you can easily run the auto-scan in the meantime."

Okay, the part about San will come later. (It involves Windows XP and a USB stick.)
Here are some photos.
I think my ash value is full, right?

Oh yeah, my dongle isn't working with my new PC - picture.

Sorry, aber Du bist kein Kunde, daher setzt Du Dich bitte mit dem Verkäufer Deines Geräts in Verbindung, denn der hat an Dir Geld verdient und ist damit auch für den Support zuständig. icon_idea.gif

Furthermore, your images are from two different systems, and neither of them is ours. icon_rolleyes.gif
