A friend has an 05 d3 tdv6 manual, It keeps going into limp mode when he tows his caravan ( it is a large heavy one) usually when he goes up a long incline. Would a diagnostics pick up the problem or has anyone any ideas.
Thanks

hi and welcome

more often than not its the turbo actuator arm sticking , may need freeing up and grease adding , is tight gaining access to it , via the passenger side , there's a u tube video in how to free them off

also take out the map sensor and ensure it's cleaned out

when it goes into limp mode it will log a fault code which a diagnostic reader will display, as it's best to get them read first before investigating , as the codes with indicate what's going on

hope that helps abit

Mine did this. Was the turbo actuator. I free'd it off and not had a problem since.
