Focus 1.6 diesel 2010. Eml light on

[french crap fanatic]

Hi,this is a regular customer he said the eml came on when going round a round about!
I had three fault codes recorded
U0416 invalid data received from abs control module
P0234 engine over boost condition
P0490 egr control

The codes erased and didn't come back even after a two mile rd test,but as ever we have to wait and see which codes come back first.
The one that concerns me is the u code,as this might be a can fault or some other multiplex issue.
Any ideas anyone?

Could do with some freeze frame data to determine which code is likey to have illuminated the warning light.

U code maybe historic
Wouldn't be on overboost going round a roundabout

Most likely EGR fault

Do you have a description with dtc's

Engine over boost could related to egr as control vacuum pipe work is shared. Also had control
Solenoid fail.

U code could be historic or a consequence of the other 2 codes

Will wait to see if he comes back and what codes have returned.
