Code u0055 and no radio Peugeot 508

richardsheil

Hi,

a friend has been offered a Peugeot 508 for a good price but with the radio / nav unit not working and the check engine light on.

The code as read by my cheapo reader is u0055 which per google relates to Canbus D error.

The question is does anybody know the seriousness of these errors and whether they can be resolved reliably and cheaply?

I seem to remember ROW is a specialist on this and could perhaps comment on this potential BSI unit problem.

And are the two errors related?

Thanks

Richard

Not so sure about this fault code but going by the info i have attached it points towards the CAN network down or engine ecu fault.

Maybe the seller was told this by the dealer and that's why its going cheap...A new ecu in the dealers would work out over a grand coded so there not cheap....then again it could be just a fuse that's blown and pulling down the CAN network.
