Hi, anyone knows what this is about? VCDS Auto-scan output: 934149 - Rain/light recognition sensor B1366 76 [008] - Wrong mounting position Intermittent - Confirmed - Tested Since Memory Clear Freeze Frame: Fault Status: 00000001 Fault Priority: 2 Fault Frequency: 4 Reset counter: 126 Mileage: 272226 km Date: 2019.12.12 Time: 18:08:17

This may be true for normal driving, but when regeneration is active fuel is injected in 4th stroke so that DPF heats up more quickly. So, I think, more revs, more heat to DPF. I tried this, and in winter I end up with DPF warning. Again, I cannot discern between DSG behavior in normal driving and during regeneration so I think is cheaper to switch it to manual and end it with higher revs.

Imagine lots of everyday short trips (5-10 min drive) in town without hills. The system is dumb. Once it starts active regeneration it restarts it every time you start the car again (and get past 50 km/h I think) and in a few days driving like this you get DPF light in instrument cluster. Even if you don't end up with DPF light, it consumes extra injected fuel every time you start the car. So my method is switch DSG to manual -> get at least 2500 rpm -> drive like this 5 - 10 min -> park the car and see if revs are below 1000 rpm and start/stop engaged, if not drive some more like this until it completes. If the higher revs were implemented in the software it would be even more obvious of active regeneration taking place. Maybe it's part of the VW policy to not do so.

I don't agree. ECU does nothing to DSG operation during active regeneration. No higher revs, no different regime of shifting gears. Nothing. Driving experience is the same like normal driving. Only clues of active regeneration taking process is disabled start/stop at idle, idling at 1000 rpm and subtle engine shake if you floor it when stationary (rpm goes to 2500 rpm).

Makes sense. But if you live in a small town without hills and you make only short trips, revs are inevitable. Especially in cold weather.

On my 2013 2.0 TDI Estate that's not true. I must switch to manual to obtain higher revs to end regeneration.

Thanks aki78 !!

Hi. Does anyone knows where can I buy this sponge things (marked red)? One of them was missing when I bought the car from a previous owner. I have bad vibrations at about 950 rpm (2.0 TDI) Thanks!

Gizmo68 in Superb MkIII VCDS Adaptations post says Is this also applicable to Octavia Mk3 or will it generate DTCs?

multi collision brake fault it was. DTCs cleared, didn't come back. Thanks once again.

Thanks guys. Generic OBD scanner shows no fault codes. I will try to erase it when I get hold of VCDS.

Keep seeing this message every startup for a few days. Anyone had this one? Common culprits on mk3 for it? I don't have vcds yet to check it out. It's 2.0 TDI DSG MY13 220k km. Thanks
