DSG chattering

Misfire

2013 Passat TDI SEL w/DSG 230,000 miles. I started getting a chatter in 3rd gear under acceleration. If I put it in manual mode and down shift it would go away. It has now started doing it though all the gears. Hard acceleration helps it go away a little. Dealer has done all my service on time. No tune yet, planning on Malone stage 2 with DSG tune in November. I have had flywheel replaced around 160,000.

who did the DMF replacement? what parts?

were there time/milage stamps for those codes? If a DMF is failing (again) I don't think there are any codes that could get tossed.

Scanned 10 am today. Don’t think DSG issue now.

Could it be an injector?

any update on this?

probably cylinder 1 glow plug needs replacing

Try swapping #1 glow plug with another one, and see if the fault follows

If the glow plug is not the cause of the problem, then you need an injector

Why not replace gp's as a set and rule that out, after all they have 300k on them. The chatter described sounds more like random misfire.
