    How do you know when it's doing a regen.

    An acrid smell and the exhaust note changes slightly, more of a burble tone.

    Though the manual says a green light should come on once a regen has completed but never seen one on either car.

    Where does the manual talk about Regen? I searched my app and "regeneration" doesn't appear once, nor are there any dash lights listed showing anything related to emissions function aside from the glow plug icon.

    You do get a bit of a burnt smell, different from the paraffin smell at startup. I only notice it in my garage when I pull in, and it's pretty rare. That likely indicates a regen cycle that's been interrupted by the completion of a journey.

    The iGUIDE mentions th e green warning light in the section on warning and information lights. DPF is mentioned three time red ! Amber and green.

    These descriptions do not appear to be in the stand alone section on warning lights

    Ah, now I see. It states, "The Diesel Particulate Filter (DPF) lamp illuminates briefly when a successful DPF regeneration process has been carried out."

    I can honestly say I have NEVER seen this lamp lit...it must be very brief indeed.

    There's also an amber DPF lamp that "illuminates when the DPF has failed to regenerate and is starting to become full. The lamp is accompanied by a message in the message center. Follow on-screen messages, if it is safe to do so."

    Presumably, this is the indication to tell you to go for a drive at higher engine speed to force a passive regeneration.

    I have also never seen this lamp lit.

    In other news, the search function in the iGuide is apparently useless...zero hits on "regeneration".

    I have not seen the Gen lights either, more likely to see northern lights maybe

    Just had a service. All the paperwork on completion of the service says I must return in 1 year or 16k miles which ever is the sooner. Not even left the forecourt, just checked the vehicle info and it's saying next service 12150 miles. Must be my style of driving.

    How many times did the stop/start activate on your way out? Whistle

    Resetting the service counter clearly doesn't erase any memory that's used to estimate the distance to next service. Otherwise one would expect the counter to read 16,000 miles immediately after reset.

    It's an estimation only...one reason why I plan to test my oil. If the actual dilution is well under 6% then the service counter could have a problem. Which would be good news, I think.

    Maybe I'll test it before I take it in, and if it indicates the dilution is well under 6%, I'll drive it for a while longer, test it again, and then take it in once it gets near 6%.

    This after an update to my iGuide:

    Thats just very disco exagerating everything to the max as usual. Take his info with a large pinch of salt. Or read it in a salt mine.

    So my next question do you think it would be better WRT oil dilution if you could kick off a regen manually whenever you feel you can satisfy the conditions on possibly more occasions than strictly necessary as opposed to it doing it automatically and not completing a number of them. Is more better?

    That iguide text looks to be identical to the DS handbook: just the standard boilerplate advice for DPFs. The problem for the DS and D5, though, is that in the real-world active regenerations take much longer than expected which is why we are all saddled with excessive post-injection, oil dilution and early service requests. JLR would like you to believe this is caused by your driving style. Or the fairies. Anything but a design fault.

    Perhaps internally they know full well what the problem is but they can't ever change the documentation as that would be an admission that a general fault exists. However, in an unguarded moment, an executive office manager sent me a letter quoting advice that had presumably come straight from engineering without first being checked by the politburo. In a propaganda war this is the sort of thing that gives people the opportunity to judge for themselves whether the company always tells the whole truth. Read alongside JLRP00100, it looks very much as though like there is a consistent, rational explanation exists for the issue.



    I stress that this was written in relation to the L550 - not the L462. But when the end-users of both vehicles are experiencing the same problem, both also included in JLRP00100 - worse on the D5 from what I have read - what else to conclude?
