VW T5 1.9TDI Engine: BRR VIN: HCY - 05/2006 163,000 km

Hello dear diesel engine enthusiasts,

In the case of the aforementioned vehicles, the DPF can only be regenerated using "emergency regeneration". A regular regeneration is not
Introduced. Ashes mass is 26 grams specified.

In VCDS unter "Advanced Measurements", unter "Oil Temperature"
a value of -0.9 °C is permanently displayed.
The workshop tried a different power source yesterday. However, it still produces the same result. There is a positive and ground connection at the connector. Oil level is indicated at approximately 31mm.

My question: Is the Oil Temperature value required for a normal regeneration start? Workshop technician says that only the coolant temperature needs to be adjusted.

(DPF pressure difference value is measured at 300 mbar. According to VCDS, it's much higher, at almost 900 mbar.

Thank you in advance for your assistance.

Greetings
Hannes D. from N.

Hallo,

der Differenzdruck 300mbar wurde durch die Werkstatt mit externem Messgerät festgestellt.
Die anderen Werte mit VCDS.
Wie soll ich die weiteren Werte am einfachsten bereitstellen?

Bitte kurze Info. Danke.

Gruss Hannes D. aus N.

Wenn das Motorsteuergerät 900mbar Differenzdruck misst und eine externe Druckanzeige sieht nur 300mbar, ist der Fehler doch klar.
