    I done the same as you and mine looks good too . One thing that did concern me was there is a piece of insulation in the engine compartment that runs from halfway down the strut tower to underneath the brake booster that butts up against the firewall near the plate. I pulled the corner of it up and it was soaked . Looks like the rain runs down between the bonnet and windscreen onto the insulation then has knowhere to go which is a bit of a worry. It might pay you to have a look under the insulation to see if any rust has taken hold.

    Given that the plate is the only part not electroplated, it gives me hope that there won't be further rust when i pull it apart.
    Holden spent a fortune on engineering and i cant believe they didnt forsee this problem.
    All the years of a labeling Holdens as rustbuckets clearly didnt make a difference.

    My wifes Hyundai is close to 10 years old and is has no signs of corrosion anywhere.

    If the corrosion in this plate has the potential to weaken the brake pedal mounting as Fu suggests, and the problem is common to VE's, imagine the number of vehicles on the road now which could be seriously at risk. Imagine too the potential for cars being knocked back at rego time once the motor trade becomes more aware of the extent of the problem.

    Imagine Holden running to the bankruptcy court following a class action from VE owners.

    350,000+ cars x their quoted $7,600 to fix.

    Just took a look at mine from under the bonnet.
    It’s perfectly dry and what I can see there is no sign of rust on that plate.

    Some VE S2 and VF have that sound insulation panel and the smaller one behind the booster omitted. (Maybe for cost more than design)

    Couldnt agree more VS5.0 or maybe it will be a safety recall.

    I intend to do nothing at this stage other than take a close look at that plate inside and outside now and then.
    Next time we are out in the rain, I shall pop the bonnet and check how wet that insulation is.
    If it's wet then I would leave the bonnet up in the garage, to dry out.

    It can be removed. Wear a mask. Also as I mentioned, it isn’t on all models after and including S2. It’s a messy job!

    I haven’t installed a new one, or the one hidden behind the brake booster, instead adding to the internal insulation.

    The part that rusts is not an expensive replacement part. It is about $180 to buy new but costs a shitload to assemble back into the car.

    I'm quite sure you'll find out if the insulation gets wet simply by giving the car a wash.
    I just had a thorough inspection of our 2011 Series II SV6 and I can see where the insulation panel that spans from the strut tower down through under the booster has been getting wet. Had to clean out a shipload of leaves first which was made easier by removing the horn & bracket.
    To my relief the panel appears as new as the day the car was built. Can even see the yellow QC paint dot still on the panel in behind the booster with my torch and inspection mirror. Times like these a good quality Borescope would be a great piece of equipment to own.

    You're right, they come in handy for many things. Just need to get a flexible one now.
