Hi.
i have a 2011 Barbarian 2,5D. i have just had the injectors serviced and then 3 off them coded back in. the 4th couldn't be read. the issue i was having was black smokes on hard turbo boost. it has got better, but should the 4th be done and would it make any difference to tyhe black smoke?
i have no loss of power and good fuel economy. in fact it goes very well. the DPI light is not on and no fault codes showing.
the second issue it has, is at 1500 to 2000 RPM it has a knock and then goes dead silent. has anyone had that before?
any advise would be appreciated.
rob.
