1.9v 16v JTD P0238 (logs attached)
Hi, I've been struggling with this P0238 (Turbo Overboost) issue for a while now.
A local private mechanics changed the vnt vaccum solenoid to start with.
But I realized that he didnt replace it with an original solenoid (looks completely different) , so a new is on the way from ebay.
He also told me to change the turbo actuator which i did today but after that i got even higher values in boost pressure.
I have also cleaned the EGR & MAP sensor.
I get the MCSF (P0238) usually in 5th or 6th gear in low revs or when pushing down "too much" on the gas pedal.
Also the car drinks a lot of fuel, around 8L/100km or 35MPG(UK). Even tho the on-board comp. says 6L/100km (47MPG).
I will try Wynns diesel formula gold along with the EGR spray to clean up the enginge and turbo.
Im posting the logs I took today and before i changed the actuator. The picture where boost pressure i yellow is from before the change and the pic with boost pressure as green is with the new actuator fitted.
Any thoughts on this?
