Hi everyone .
I have ran into a problem with my 1.3 jtd multijet . I’ve heard the wastegate actuator blow off when changing gear at low rpm for a few days then it threw up P0234 (turbo over boost ) and P2563 (boost control position sensor A circuit Range / performance). Exhaust note changes and uses a lot of fuel , I expect because it’s not burning it. You can reset the codes but the performance is still affected and the lights will come back on eventually.
I first checked the actuator lever and this was operating by hand and getting the full travel .
I then did a Vac test on the actuator and it held vacuum .
Then vac tested the vac pipes from there to the boost switch and then to the vac tank and then to the vac pump . I can’t find a fault in that system with the vac test.
I did change the boost control solenoid / valve as I had access to a Combo Van but alas the fault continued even though I did think it initially fixed it for about 10 mins .
The actuator itself is fully down at turn off and fully opens for a second when you turn the key and goes back to home position.
Can anyone help me with narrowing down the problem ? Or if I am missing something on my test ?
Even though the EGR isn’t on this vacuum circuit could this be worth looking at or if there was a problem with it would have threw up an EGR code ?
It’s the engine that doesn’t have the small vac pipe joining the actuator to the turbo .
Any help would be appreciated . I could guess a few things but it would just be guessing so abit of expertise would be brilliant .
Thanks
