Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

It also turned out that the rod is about 5mm shorter than the OE one, to the extent it won't be fully 'open' without modifications.

I initially ordered an OE 997 actuator as it was half the price of the 996 one (but looked identical) but the delivery date was uncertain, so I ran with the Designtek one from Design911 for only £39.
Leading evidence: 'rod is about 5mm shorter than the oe one' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'rod is about 5mm shorter than the oe one' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Run with the designtek one' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I noticed the other night that the PSE has become a bit slow to shut up on one side.
I assume either a problem with the vacuum pipe or the valve on the silencer.
Is either bit home-servicable, or is it another one for the list for the annual service?
If the actuators are actually moving, then I doubt there is a vacuum leak as they wouldn`t work at all if there was, I would give the moving parts a douse in WD40 to start off with and then keep operating them to work the oil in, don`t forget both ends of the flap hinge pins.
One of mine was seized when I first got it. You can just about reach up and touch the actuators to see if they are moveable.... try the good side first to get a point of reference and see how much effort it takes to operate one, it's not much effort.
I got mine working by heat shrinking several WD40 straws together to make them long enough to reach, then a sparing application of gt85 where they actuate.
Usual rules around spraying anything near hot exhausts apply :thumb:
To give a conclusion to this, I got under the car and tried wiggling the actuators about. The fault (perhaps unsurprisingly) was that the O/S actuator would not move.
The reason is that the mounting bolts on the actuator had rusted through, so it was rattling about in the bracket. Unless the rod/actuator is correctly aligned, it won't move. Hence sometimes, if it happened to be in the right place, it would work.
Now I just need to find a way of bodging a repair to hold it in place until I work out how on earth to get the actuator out of the bracket and replace it.
And finally...
Fixed this weekend with a new vacuum actuator.
I initially ordered an OE 997 actuator as it was half the price of the 996 one (but looked identical) but the delivery date was uncertain, so I ran with the Designtek one from Design911 for only £39. This is fine, but comes with no fasteners nor a ball joint. It also turned out that the rod is about 5mm shorter than the OE one, to the extent it won't be fully 'open' without modifications.
When we removed the old actuator the ball joint crumbled as it was corroded, and goodness knows where you'd get one of those separately. Luckily, a genius friend managed to weld up what remained of the ball joint to some nuts to not only repair it but also extend it sufficiently that it fitted.
Anyway, happy days, now all working perfectly
