[kimmoW639]

Hi

I have Vito 120cdi bus 4/2007 with turbocharger A6420904980. That charger seems to be very rare.
Can someone tell me differencies of the foowing turbochargers:
A6420906980
A6420905980
A6420904780
A6420902980

Can I use some other turbocharger to my Vito than original part number?

Thanks

Kimmo

It may be the compressor and turbine sizes are different, but it may also be nothing more than the outlet spigot faces a different way, in which case swap yours over.
