F1r3walk Posted July 23, 2016 Share Posted July 23, 2016 I have a recurring leak from my power steering pump on Audi 80 Cabriolet 2.6 1989 it comes from a blanking plug on top that contains a small spring below.The plug has a large posidrive x on top for tightening it back in to the pump,I have had the car just over 1 month and it has had 2 O rings and yesterday dumped all fluid again so I've fitted another one.I did notice on doing this that an O ring on another part of the pump was a red colour and wonder if normal black ones are affected by the fluid,any ideas people?

Trevor Posted July 26, 2016 Share Posted July 26, 2016 You could try wrapping some PTFE tape around the thread of the blanking plug before refitting. I'm also wondering if it could be because it has two o rings and it maybe should only have 1 o ring fitted? Red o'ring usually signifies it is suitable for higher temperatures (Viton material) Let us know how you get on with it Quote Link to comment Share on other sites More sharing options...
F1r3walk Posted July 27, 2016 Author Share Posted July 27, 2016 Getting really frustrated now,Audi don't even have this pump on their system anymore,the pump is a tandem pump which does brakes as well,decided to have it removed and refurbished,fingers crossed the guy doing it says he's done them before,replacement from Europarts nearly £600,gulp.

Nick H Posted January 2, 2017 Share Posted January 2, 2017 Mine just went 3 times. Fluid every where all times. Even said to bloke at parts counter the oring was small profile but no he only shows me the fuel type oring after 3 ring splits. All good now x fingers been 3 days now. All sweet. Replacing fluids was expensive part. Not cheap fluid from petrol station 1 Quote Link to comment Share on other sites More sharing options...
