Thread: What happened to your D3/D4 today?

Nice. So it’s like owning a 3L

But your crank won’t fall out.

Have woken up to the car on bump stops out the front for the last two days. I replaced the front block a few months ago so I'm hoping it's the rear. Can someone please remind me the fuses to pull to stop auto leveling? I'd pull the battery but I just put in a Traxide system and fear I'd break something

I’d expect them to be reasonably quiet looking at that block layout.

Some more observations on the EGR valve operation on the D3 today after a longer drive. The only time the valves actually fully close was at speed on the freeway and you are accelerating. So for those few seconds the valves go to 5%. Once at speed or you back off they re-open.

No wonder they get so solid with gunk.

Perhaps time to think about bypassing and removing.

I blanked mine 2 weeks ago, left all pipes in place and my egrs were/are still functioning. No engine light on the dash either, I removed the manifolds and intake Y piece for a thorough clean as they were gunked up especially the top intake ports with their redundant flaps.

I wonder if it would be possible to create a closed loop and feed the output signal back into the position signal. But leaving hooked up and tied out of the way does sound simple.

And while your EGRs are still functioning you will not get an engine light. If they fail, even though you are blanked your engine light will be back on. While the ECU still gets the expected signals back from the EGRs the light stays off. Wrong or no signal and the light comes on.

If that happens I get the patch.
