Hi All,
I am a newbie in the Cayenne world, but have been a seasoned 996 owner since 2015 and used to be extremely active on here until a house renovation robbed me of hobbies and time! Lol
So recently had the fortune to add a beautiful 2012 4.8 V8 Cayenne Turbo to the drive way… a car I have lusted after for far too long. It’s a beautiful example, 70K mileage, extremely clean and has been well loved and was spec'ed to an extremely high level when new.
Sadly I incurred an airlock in the dual Power Steering and Suspension Pump early on in ownership due to a mechanics over sight of incorrectly filling the system. This created a horrendous noise, but thankfully was easy to rectify.
However when investigations of this initial issue were underway – my Independent garage who have very limited exposure to this model Porsche V8 engine – commented on a slight tensioner rattle noise / chain rattle coming from the lower sump area between 900rpm and 1100rpm. Where the oil pump resides in the engine.
This noise is consistently repeatable, there is zero metal in oil etc. engine is smooth, powerful, smokeless etc and once driving you’d never hear it, especially with under trays on etc. – so realistically – it could be a sound that unless, under it looking for a noise, with all trays off you’d never notice it.
However my paranoia is now on overdrive and I just wanted to know does anyone know if these engine omit a chain / tensioner rattle from this area of the engine at that RPM, just as a characteristic (a trait like when a Mezger engine starts up it sounds like a bag of spanners and bolts)
Or is there something on these engines to be concerned at?
It’s a first world issue I know – but I am so frustrated, as I am now looking at the car of my dreams – which drives faultlessly, doesn’t smoke, is quiet and is extremely powerful – but can’t help worrying if this is the start of an underlying problem.
The garage (a highly respected Porsche independent) also are at a loss and have stressed that from here on out they’d be looking at changing components to see if this ‘fixes' the slight noise – but have also stated this could just be a by product / trait of the engine design.
There are zero issues I can find on here or on Google that relate to this issue either. Plus Porsche parts have never sold a lower oil pump through their parts system in the UK either on that model, so that alone tells me god forbid if this was an issue its a one off and serious bad luck.
So I am at a loss and would be grateful for any owners or experienced hands of this model to share their experiences. Just in case we’re chasing ghosts. Or even if someone knows a specialist who is well regarded in the UK for servicing these v8 Twin Turbo Cayenne engines.
Thanks to all in advance for any insights. :thumbs:
