    2017 Discovery Td6 First Edition Farallon Black

    Update:
    It was the low pressure (in tank) fuel pump. Apparently the fault shown was a short circuit but they replaced the pump (took weeks to get one) and that problem has gone away.

    I hadn't updated here as I threatened to reject the car as it had so many other faults, but the dealer agreed to repair everything:
    Front lower suspension arm (bad tracking)
    Front stabiliser bars x 2 (rattling over bumps)
    New battery (would not hold charge)
    2 x wheel bearings (left side) - terrible road noise
    New aux belt and tensioner - rumbling
    New front discs and pads - vibrating

    I still needs a wheel bearing on the right side, there is a strange grumbling when coming off the throttle from the air intake in the wing, the GPS aerial is dead (no Sat Nav and it's 2016 apparently) and the wheel alignment is off. But I'm a bit bored now. Anyone want to swap for a D4? Smile

    Also - the ride is terrible - side to side rocking - never a problem on the D4.
    Very Happy to prevent depression!

    2018 Discovery TDV6 HSE Fuji White

    Hello folks,

    New to this forum and new (to me) discovery owner. 2 months ago I purchased a 2018 HSE 3.0L TDV6 Auto from an independent dealership. I had spent considerable time looking and found this one with full Land Rover service history and timing belt replacement at 70,000miles last November. I purchased it at 75,000 miles and have driven 4,000 miles.

    Two Fridays ago my wife was driving and like Scwede, just lost power and died. Recovery ensued and now sitting at a local independent garage (we live at the opposite end of the country to where I purchased it).

    Photo attached shows catastrophic failure of the RH camshaft pulley spoke and reading on a disco 3 forum is quite a common occurrence!? I am now in the midst of assessing my options as to whether I pursue the dealership I bought from or Land Rover who performed the timing belt replacement in the hope of re-cooping the considerable expense I am going to be hit with...

    The disco 3 thread also said that incorrect belt tensioning leads to more stress on the RH pulley than left that can lead to this type of failure.

    The local independent garage have already stated they wouldn't entertain a repair and are just recommending I go straight for replacement.

    Any advice would be greatly appreciated.

    I would not automatically jump to a full engine replacement, not all pulley failures are catastrophic for the engine , often they can and are rebuilt at a fraction of the costs of a full replacement engine.

    In terms of come backs if its within 90 days you may have some come back on the seller if it was a trader, Landover will not provide any cover at all, especially if the work was done outside of your ownership.

    Good luck its a difficult place to be..

    First of all, I feel your pain. I bought mine last November, exactly the same mileage and also from deepest Englandshire. No cam belts done on mine though, I did them myself when I got it home.

    Whoever fitted that timing belt would have to have overtightened (or incorrectly fitted it) by some degree if it's shattered the spokes on the camshaft pulley. Either that or the pulley has previously developed stress fractures leading to the failure of the spokes after the belt replacement. The increase in tension from a new belt will put extra stress on the pulley, especially if it's incorrectly tensioned.

    Although the belt itself hasn't snapped under tension, it's been split lengthways in a couple of places from what I can see.

    Looking at your photo...to me...the camshaft pulley adjustment looks a bit weird... judging purely on the adjustment gaps behind the pulley bolts. The belt should be fitted with the slack going anti-clockwise from the crankshaft pulley by loosening the bolts and rotating the camshaft pulleys anti-clockwise against the camshaft locking pins when running the new belt on so that the final belt tension is taken up by the tensioner pulley (the brown one at the bottom). That would usually put the gaps behind the pulley bolts at the opposite side of the bolt heads from where they appear in your photo... Unless those bolts have been loosened before taking the photo of course.

    The above is merely my limited opinion of course...I'm judging purely from a photo.

    It used to be good practice by experienced fitters when replacing a timing belt to do a 'ding' test on the camshaft pulleys (removing them and tapping them with a spanner) before refitting them along with the new belt. A simple trick...but like a cracked teacup... a cast pulley won't 'ding' if it has stress fractures.

    Personally...and if it was my vehicle...I'd lay blame squarely on whoever replaced the belt. The dealer who sold you it will no doubt be as exasperated with the failure as you are and may offer a replacement vehicle (if anything) rather than tackle the repair, probably as they'd have to have the repair done externally through a Land Rover specialist rather than them repairing it in their own workshop...if they have one. They may pay for you to have it repaired locally (to you)...but I honestly wouldn't bank on that.

    Again...if it was mine...I would possibly do the job myself after further inspection and seeking reparations from either the dealer or the Land Rover centre where the belt was fitted as the chances are, besides the pulley itself, the damage may very well be limited, as Trantorman pointed out in the post above.

    It's a difficult one...and I certainly wish you all the luck in sorting it out.

    Jeez, did I make the right decision to also change the pulleys when my belts were changed, JAS advised me to have it done as they were aware that it was a known issue. I think they fit proven quality items rather than Landrovers own. I can't understand why they're not changed as a matter of course at belt change as there is practically no extra labour charge just the cost of the pulleys. IIRC extra cost was £120, looks like fantastic value for money now!

    Aye, I changed both of my camshaft pulleys (and tensioners and all the free-wheel pulleys) when I did the belts...just in case. I'm about as geographically challenged as it gets so it was a prudent replacement.
