Thank you for sharing your experience! In relation to that, i have some questions: How do you feel the engine with the 5w40 oil in? Is it smoother? Any strange behavior? Are you planning to keep using the 5w40 oil, if the oil consumption is small? What is your mileage on the odometer? Best Regards, Mihai

It happened to me also, but it will work....

You are wright! I was only thinking for the brake fluid reservoir not for the clutch port.

You have like 166K km... if you think your dpf is not clogged( inside visually inspected/ controlled)/ car in good running condition....play around 30 to 35 grams of ash mass( i play with 46 grams for 230k km)....see what is coming after. The thing is that after every adaptation of ash mass you will get, soon, a new regeneration....this is happening to my car anyway. So....how to adapt ash mass( for EA288... maybe it works for EA189...not sure): VCDS - 01 Engine -16 Security Access(enter code shown by VCDS)-10 Adaptation- Adaptation of ash mass( on the top you will see Stored value=actual value, on the bottom New Value= whatever value you would like to insert)-Press Do It-Confirm....and it should be done. For everyone reading please realize that you do this on your own risk....if anything bad happening i am not to be blamed....i am just sharing some of the experience that i had with my car.

Hello, You have to check the clutch pumps( one on the clutch pedal/ one outside the gearbox), if here are 2, or the clutch pump and the clutch bearing if it is inside the gearbox activated by brake fluid, check also brake fluid level or if you have any brake fluid leakages between the engine and the gearbox. Pay attention to the brake fluid level!!!!! That can become dangerous!

Hello, It is not a good idea to set this value to 0(zero) unless you have changed the dpf with a new or professionally cleaned one. I would suggest you to set the value for the oil ash mass according to the kilometers on the instrument cluster. After you do this the car will regenerate, and it will start again from 18-24% depending on what ECU will say.

I have just checked one 1,6 l, CAYC engine Octavia 2FL 2011 229630km The measured figures are: IDE 00427- difference pressure sensor- 5,56hPa IDE 00433- oil ash mass -56,32 grams IDE 00434- soot mass calculated - 11,56 grams IDE 00435- soot mass measured - 2,76 grams Regeneration took place 76km ago. Did you played around with the ash mass value, in the sense of adapting it?

I see good values. With the ignition on, engine not idling what is the differential pressure sensor value? I think it should show 0( zero).

You are wright.

That's even better....it is the latest version...😀

VCDS Version 20.4.2 Engine- Advanced Measuring Values: IDE 00433- Oil ash volume IDE 00434- Soot mass calculated IDE 00435- soot mass measured IDE 06059- oil ash mass IDE 06060- filter ash load limit I hope it helps with your car and with your version of VCDS.

Yes it does...but not that much, on idle you should get 12-13 hpa. What is your value now?

All the figures are measured with VCDS. The correlation between the mass and volume is given by VCDS in two separated channels. 45Grams of oil ash does not mean that dpf life is finished.... 70 grams is the service limit for EA 189. The DPF was replaced with a good working condition one from a damaged car with not so many km( visually inspected with an endoscopic video camera, and manually tested with a thin copper wire inserted through some of the channels of the filter on the direction that gases are flowing). Before changing the DPF the car was regenerating every 5 to 10 km, with a differential pressure of 35 to 50 hpa/milibar on idling, now differential pressure is between 3 and 7 hpa, and the car is regenerating about 350 km mixed driving.....i think this is ok for EA288 engine.

Hello, For 2.0 tdi 110kw 2016 max oil ash mass is 80 grams. Soot is what burns during regeneration....ash is what is left in the DPF after regeneration... and slowly killing it. My case: i had 111,2 grams/ 0,27l of ash in the dpf (the car was regenerating every 5 to 10 km) and it was full of ash....white powder, turbocharger variable geometry blocked and hot side of turbocharger covered in sticky white powder

Hello all, Just a car enthusiast posting here first time , please excuse my English, as it is not my native language. I do have the same problem with my 2016 Octavia 2.0 TDI,110kw, CRMB engine code: HIGH OIL CONSUMPTION, i own the car since July 2021, bought 2nd hand from Germany. Initial symptoms were: regeneration every 5-10 km, very high diesel consumption, very high oil consumption, throttle response not so great but not so bad either, no errors on VCDS scan.... and i started to study... So far i have changed the following: - the differential pressure sensors( there are two on this car) - the Diesel Particle Filter( the one i removed was full with ash ... some white powder) - the turbocharger( blocked variable geometry and ash ) ... the situation improved, very good throttle response, regeneration is about 350 km mixed driving, fuel consumption is 6-6,5 l/100km.... but the car is still eating a lot of oil.... about 1L oil for 600 km, other than the oil consumption, the car is starting/idling/running really nice, with no strange noises from the engine, injector compensations are between -0,2 and +0,2. With this injector compensation values, i don't believe that there is a problem by the cylinders. I read that one of the reasons for the oil consumption problem can be the valve seals not sealing properly....but i don't want to open the engine if it is not necessary. What i want to do next is to remove the rocker cover to visually inspect , to clean, and to change the CCV diaphragm....maybe the turbocharger is absorbing oil through the CCV, due to broken diaphragm or it is leaking oil by the seals due to clogged/dirty CCV system( too much pressure into the crankcase= restrictive turbocharger oil return line). I am also thinking to run an engine flush to remove some of the carbon deposits from the cylinder walls ( if there is any) and hopefully to obtain a better sealing by the piston rings. I hope i can help a little with my experience and i would appreciate any other ideas. Thank You!
