I'm having real trouble with this to be honest. Cars on around 85k so nothing major.
Took the pipe off and cleaned it, tbh I was quite surprised that there wasn't alot of carbon deposits their.
Im contemplating replacing the whole egr, it's quite expensive. Wondering if it's a DIY job.
When I've inspected the plunger unit (the black cylinder in the middle of the pic above) it seemed really sticky. So when I pushed it in, it was a little reluctant on the way up and down. Is it possible to just replace that part?
Before replacing the EGR are there any other diagnostics I can do, it seems to flash P0403 up alot.
Just really hoping it's not the manifold.
