I have owned the car 6 months and it was on its second oil service and mechanic said he thought there was a leak coming from the rear crankshaft seal. There is a little oil in the tray but not liquid but still a tiny bit moist. Doing about 300 miles per week. I know the RMScan be a problem but it’s not losing any oil and I was thinking about using an additive to try and hydrate the seal to see if it stops. Any recommendations on additive or indeed the leak and if I am not losing any oil is it an issue? TIA

Lots of info on the web regarding Cayenne oil leaks , just off to try and address the issue(s)  on mine.

 

There seems to be a couple of places it leaks from , sump plug / oil pan to crankcase joint and from the housing around the flywheel (bellhousing in old terms)

 

Mine is leaking from the sump washer due to it not being replaced at the previous  service and also from one area around the sump.

 

Bad news is that if  it needs the sump resealed properly or the bellhousing leak repaired properly then it is an engine / gearbox / subframe out job that runs into many ££££.

 

If you are doing 1200 miles a month and the undertray is just a little "moist" and no dripping oil present then just live with it as it would be an expensive repair for all that is leaking.

It is always helpful if you tell us the exact model and year of the car.

Sorry, I am new here and thought it pulled the model through from the profile. It’s a 3L Diesel MY11.

Thanks for this. My plan is to keep an eye on it and see if it gets worse. Any thoughts on additives to restore any seals that may have perished?

Never considered seal restorers , dont think it would have helped with my leaks as the sump is sealed with gasket silicon and the drain plug needed a new crush washer.

 

From what i have read the leak from the bellhousing is caused by a fault during engine assembly , so no amount of leak stopper will cure that one.

 

Funny how in certain parts of the world this is repaired under VW Dieselgate extended drivetrain warranty but here in the UK we are left to fork out the £5 -> £9k ourselves ??

Sure, they are worthless band aides.
