Thread: RRS 3.0 blowing smoke (lots of it)

" ever since you serviced my car"

id like to see how changing oil would kill a turbo just like that, unless it was serviced some were other then a dealer.

and a if a chip/tune/remap is undertectiball to a dealer computer, how about when we drive the car?,

there is heaps of info and 3L blowing smoke, google is your friend, or just leave it to the service place to fix it,

what i would like to no is tho is it worse when its cold and clear out when hot, or all teh time, or only when hot,

Not sure about when it's hot vs when it's cold, I'll have to check that tomorrow. Certainly in second longer drive today there was no more smoke, so maybe it's only when it's cold.
And yes, there is considerably more punch in power and torque since remapping.

wev had a cople of 3Ls pump out the smoke when cold and then clear out, (no they hadent run out of oil) when warmed up,

then another colpe only when hot,

then others that only after a long time of crusing, then the other end of only after alot of idling,

My mechanic tells me, my D3 is smoking due to a choked valves in the exhaust that recyles unburnt fuel. The fix is replace the valves ($1,000) or blank them off ($400). It is like a catylitic converter for diesel.

The turbo issue will also have a small amount oil use associated with it. Are you burning any oil at all?

Exhaust gas recirculation is not to elimate unburnt fuel, but to mix gas that has low oxygen content with the inlet air to cause delayed combustion so as to reduce noxious exhaust gases and to reduce combustion noise at idle and very low revs.

I also understood the EGRs to kick in on any trailing throttle - as you said when air intake is low. I must admit that I thought the ECU would cut back fuel irrespective of throttle to keep the fuel mix optimal to that EGRs would not be necessary - but obviously not.

My recent experience with Egr faults showed that the issue may not actually be the EGR - in my case it was a dodgy electrical connector which stopped the EGR from working - a play around with the connector had it working again with no faults (so far). It does pay to look at the easy things first.

No, don't seem to be burning any oil. It's quite strange, it only happens every so often, and when I actually try to make it smoke, nothing happens. Yet it'll happen of its own accord intermittently. Weird.
