Thread: RRS 3.0 blowing smoke (lots of it)

The I/C on mine was cleaned as part of the turbo replacement. Was your I/C also cleaned?

You mean intercooler? Yeah it was Graeme, at least that's what the service manager told me. Interesting, I was just driving home and thought I'd test some advice here on the forum to hold it in gear (3rd) and run it at 2,500 to 3,000 rpm for a stretch to see if it burnt off some of whatever is causing the smoke. It was emitting thin blue smoke while I maintained those revs.
Then I went back to drive, stopped, took from the lights at brisk acceleration, and bang on 2,900 revs, puff goes a big cloud of blue smoke. It stopped as soon as the car changed up a gear and the revs dropped.
Got me beat.
I think I'll have to take an LR technician for a drive.

Just for interest, today i followed a new D4 3.0l through town
& noticed everytime the driver took off at the lights there were large puffs of smoke from each exhaust pipe.
The smoke was black so presume fuel & normal.

Mine is the same....boot it and the smoke comes out. Not excessive, but compared to my touareg with the v6 tdi, it is excessive. Put your finger into the exhaust tailpipe on the touareg and nothing.....disco gives you very dirty sooty fingers. Definitely not a visibly clean output.

Greg, I am assuming that the remap was done by a reputable agent / mechanic?
I only know of one place in the UK and one in OZ that I would trust.

Re: The black smoke. They all blow some sort of smoke under heavy acceleration...........nature of a diesel.
I have noticed recently that the Mercedes ML diesels blow heaps of smoke, even under normal acceleration.

Wait until the new turbo is on and tested before you get rid of the re-map. I know dozens of people who have had the new turbo and have the re-map (not all from England though) and the smoke dissapeared after the replacement.
Out of curiosity did they tell you how they change the secondary turbo responsible for the smoke?!?

Does your touareg have a DPF?

Our 3td discovery 4 has had it fixed geometry turbo replaced after extensive
testing. It is the fourth that the Dealer has replaced and seems to be more of a problem with the earlier discovery 4s.
