Vehicle compatibility
The ECU is listed for: VW T4 / LT 2.5 TDI. The label numbers decide – OEM 074906018N and Bosch 0281010078 must match your ECU. The model and engine size alone are not enough: a different number, e.g. 074906018BG (0281010631), means a different version of the ECU.
Installation and preparation
The immobiliser is switched off in the ECU itself, so once connected there is no programming. EGR OFF and chip tuning (+15% power) can be ordered additionally, for an extra charge.
