I'm in a flat spin today
Before I changed anything on the CRD, I got 8,5 Km/L (20 MPG) with city driving, and 11.3Km/L (26.58MPG) on the highway (driving constant 120km/h (74.5MPH) for a constant 300km..
Then I disconnected the EGR system a while ago ...
All of a sudden my city driving went down to 7,8km/l (19MPG) ... AT FIRST I thought maybe it was because I was driving a bit more ...uhmmm "aggresive" with my last tank .....but then came today ....
I did the same 300km drive, at a constant 120km/h (74.5MPH), and this time I could see it on the highway drive as well!! ... it came down from 11.3Km/L (26.58MPG) to only 9.5km/L (22.3MPG) !!
This is a HUGE shock! What could be the problem????? I thought disconnecting the EGR should give me AT LEAST the same MPG if not more ??
Could it be that the ECU is set to optimized economy, and now that I've disconnected the EGR, the system get the wrong readings and causes the fuel consumption to go hay-wire???
