    Puma Owners - Does yours do this?

    Curious if this is "Normal" or not. Apparently it's supposed to be "Normal" on the MY09 PUMA engined defenders.

    1 - Make sure engine is COLD, or has not been running for at least 2 hours.
    2 - Get in and start engine
    3 - Immediately raise the revs to 1100 or 1000 or anything just above idle and hold for 1 minute

    Does yours miss and run very roughly , and blow lots of white smoke?

    To me this sounds like a sticking or leaking injector. But apparently as the man said - they all do it

    Not Normal!!!

    I doubt that the "man" knows what he is talking about. "They all do that" is the first of the excuses/palm-offs used and has been around since the motor car was invented.

    yeah must admit mine runs a little ruff on start up...no smoke...i always give it a couple of mins to warm up...it's done just over 7K now and been that same since new (7 weeks)...feels normal to me...My TDV6 Disco before was the same...

    So IMHO the smoke is a problem not the running a little ruff when cold...

    but what do i know...

    My car is a little bit noisy when cold, but I've never got it to smoke, there is barely any smoke when I have my foot to the floor, (when its warm!). Hell, I've even started my 110 in the garage with the door shut when the engine was cold, there wasn't even a hint of smoke.

    The injectors are electronically controlled, not opened by pressure, so if they were "sticking" I'd guess they were stuffed. From the white smoke I'd say there is not enough fuel pressure, and since it only happens when its cold you could possibly have air leaking into the HP part of the system?? Something the dealer will have to figure out, I'd certainly insist that you don't think it is normal.

    I take what the dealers say with a grain of salt these days, I had a mechanic explain that the clutch noise I am hearing is from the dual mass flywheel and is completly normal, he then spent 5 min's explaining how a dual mass flywheel works. I waited till he finished before I said "thats nice, but the TDCi doesn't have a dual mass flywheel."

    Because you can feel the issue as you drive off. This is a simple way to reproduce it.

    Ok - makes sense. I hope they can sort this thing out - I think it's weird that some Pumas do , some don't.

    I guess that was my point too, Pat. I was going to say originally, "just let it idle for a while", but thought I'd get shot again...

    Question

    1000 or 1100 RPM is hardly likely to spin a bearing. It idles at 900rpm
