Thread: TD5 EGR removal

I'll wait until after the roadworthy before fitting it then.

Did mine about 18 months ago. Can't say I noticed any performance change but wanted to stop the crap going back into the engine.

Have not had any buzzing problems that others are talking about.

I removed my EGR, leaving the yellow pipe in place.
Had a short buzzing sound with keys on ACC but went away almost straight away..


Removed the yellow pipe and plugged both the T-piece and the yellow connection on the solenoid,

Now the buzzing is almost constant for atleast the first 5 minutes of driving?

I pulled off the intercooler hose to the intake manifold and found what appeared be oil inside. I also took the air box cover off too look down the pipe and there was what appeared to be oil in there as well, it was on the turbo fins also.

It was liquid, i assumed the gunk that gets into the intake on a TD5 was the same as on non turbo petrol cars, the sludgy black stuff and sometimes a little bit sooty. I expected to find the black stuff in the metal flexi pipe that goes from the EGR valve to the exhaust inside the intake manifold not an oil like substance.

So i'd really like to know if this is from the EGR system, or should I be worried the turbo is leaking.

I would think that if it is in the intake and turbo fins it will be from the crankcase breather which is half way down the tube between the MAF and Turbo. Do a search on Provent.
There will always be some oil there.
The EGR will only affect the inlet manifold, and possibly gunk up the MAP sensor. A good test is to remove the MAP sensor and see how much carbon gunk build up there is. If there is a lot , clean the MAP sensor and remove the EGR valve and clean it as it will be gunged up also.
I must say I am agonising over removal as when I bought my D2 with 134KK on it the the EGR valve and MAP sensor were dirty but not so much that the MAP reading was affected.
Seeing it took 11 years and 134Kk to get to that point , I don't consider it too much of a problem.
