    Question Discovery 2 'plenum cover' (lower windscreen trim).

    Hi All!
    Been a while but it's back to the font of all knowledge- AULRO!
    Anyone had issues with new plenum covers, the plastic trim that goes under the windscreen (wipers come up through it)?
    I replaced my cracked one last year with a new genuine one. Within a few months it warped like crazy along the top edge. Rovacraft were good and replaced it no issues. But within a month the new one has also 'chucked a wobbly'!
    Rovacraft contacted LR Aus, who replied they had only had one complaint and rejected it as 'during install, the A pillar covers had not been removed and replaced, hence the plenum cover was squashed inwards and warped' ???!! Baloney, I thought, and checked mine. 1-5 mm gaps at both ends in true LR fashion. It doesn't in any way touch the A pillar trim. Made a video showing the clearance and Rovacraft contacted LR Aus, who have now said 'oh well we'll send a new one!'.
    But why is it warping? It's not that hot here (SW WA). The new cover does look a slightly different plastic to the old (more waxy and matt than the original).
    The warping seems to occur between the two wiper spigots (visible mostly along the top rubber seal edge against - or not! - the windscreen). It's almost as if in heat it is trying to expand lengthwise and the wiper spigots stop it, so it warps. But the original never did this (it just cracked in half!).
    And ideas or experiences?

    I had the same issue with a new one I bought about 12 months ago. Massive warping along the top after only a couple of weeks.
    Led Richmond replaced it for me. I think the new one has some minor warping now. I'll check it tomorrow.

    I recently replaced mine with a second hand piece, after a couple of months it cracked straight through the middle. I have a feeling that the mechanic may have fitted it without taking the bonnet off which inturn you need to bend it upwards to get it on. I think I notice a hairline crack afetrwards which then grew.
    How much was the new one you bought?
    Did you fit it yourself?

    cheers

    my new one has been on for about 4 months,so has gone through the buildup here in Darwin as well as a few 40+ days at tennant creek,still as straight,Bought from TRS perhaps they use a different supplier,Just wondering given the comments about the wiper hole interfering are the left hand drive wipers in a different position.if so perhaps perhaps the plenum is different.

    Wipers left and right

    Hi Lewy,
    They are universal - there are blanking plugs in the Left hand drive wiper holes.
    The holes in mine are in the right place, not interfering, just it seems that the warping is 'between' them - as if when the wiper spigot nuts are re-fitted, they clamp on the plastic and stop length-wise expansion?

    Hi Singlecell,
    What were the results of your warping analysis?
    Cheers,
