See GenBoard/Manual/WBSensor for information.


There are many similar types. Often the difference is just the length of the cable.


LSU4.9 - with smaller connector

This (currently not used by us) sensor has smaller (but same "U" shape) connector.

Measurements seem to show that it requires

If it's used, ever, it requires special care during configuration (since connector is different, this might not be that big problem).

Bosch LSU 4.9 vs. 4.2 (fex. '6066' sensor) indeed differs somewhat technically.

  • Exhaust gas temp 930 C vs. 850 C deg (allowable continuous ? - datasheet does not give a clue).
  • Heater supply / power; 7.5 V / 7.5 W vs. 9 V / 10 W
  • Lambda measuring range from 0,65 vs. 0,70

Mini-LSU 4.9 sensor seems to be (temp etc. vise) similar to LSU 4.2.

Bosch has AWS_LSU 4.9 unit to connect/interface two Mini-LSU 4.9 sensors to CAN.

The connector housing itself is a problem. Only possible to buy from VW (part dealers). The MPT receptracles and small rubber seals shouldn't be a problem.

pinout - THE big question

The nernst and pump- would be the question. Seems to be reverse of the above:(pin6 black pump- ; pin4 grey nernst) but it doesn't seem to behave perfectly.


Here is a link about the pinout of the WBO2 sensor with the little connector. Theese sensors used by MOTEC.
