Hey guys. Has anyone got P15B3 error before?
It’s for fuel aditive on 2.0 HDI engines.
Have you topped it up yourself, or authorized shop did it?
B15P3 fap additive adding. Calculated fap additive level below the minimum threshold
You need to top up the FAP fluid (not to be confused with AdBlue) and then enter the top up in Diagbox.
