If a computer controls the EGR then is it worth it to block of the EGR on the 4.2... i am reading a lot about blocking the EGR but not much on the 4.2TD... I have a Ser IV 4.2TDi ST...
4.2TDi Chip
Hi there,
I have a dumb question
, I have a 05 4.2TDi STS and was under the understanding that it was a "Mechanical" engine and there were not computer chips for this engine. I was in a local tune up shop and they were sure as **** there was. Can anyone put me strait please
Cheers

Its gone. cheersThe factory intercooled had a computer for as stated the pump timing and EGR. The non-intercooled did not have a computer, or elecronic controlled pump or EGR.
The electronics on the TDi pumps are just a bolt onto the non TDi pumps, so really has reletively little control compared to the 3L.
As for EGR. Dirty diesel exhaust gasses in your intake = reduced emmissions but reduced engine life. If I had an EGR on mine, well I think you know what I am getting at.
