Today I cleaned intake and turbo on my JTDM 150HP (turbo part in new thread)
EGR disablet in software at 50,000 miles, but before then it has built up a lot of dirt in the inlet.
Schematics intake / turbo
Remove and clean Throttle body
Remove and claen Foot mount (letting exhaust from egr pass to intake)
Also clean EGR - best thing is never to use it again - just mount it and block it (best thing to have it deleted in software)
Take a look at intake (" *nal probing " with an iphone...)
Remove MAP sensor and soak intake in intake cleaner - let it work for 1 hour
Made a blockoff plate for EGR (just to be sure exhaust never return to my intake)
Kind of bizare isn't it - connecting exhaust to intake...
Assemble the whole thing again and crossed my fingers that the car starts ...
It did not
It was drowned in the intake cleaner
After 5 attempts got it started - a lot of smoke out of exhaust
Drove a long trip with a lot of rpm.
Everything ok! it starts better and does not vibrate when it starts as before cleaning the intake.
