Porsche Cayenne 2012 v8 coolant leak from rear of engine

[@naki0x]

My 2011 Cayenne TT (958) just start leaking coolant from the back of the engine on the right (passenger side). I took her apart today... intake manifold and all but couldn't see the leak. I even popped off a few hoses just to make sure there was no corrosion. All was good. I'll do some further inspection from underneath behind the engine. I know if I accelerate quickly it exacerbates the problem... Update: I was able to visualize the leak. It's under the right rear of the engine (passenger side) just above an exhaust cat. It appears that 1 screw vibrated out of the coolant distributor and the pipe it holds is sitting 2mm to 3mm loose. I believe this is a feeding pipe of coolant, possible directly from the filler reservoir. The part# 9A7-001-821-00. I think It's an easy fix. It's within arms reach from the chassis while under the car. Thanks for your video!

Thank you for your detailed reply. I don't have the same issue, but when it does occur I will be able to make more sense of it because of you, so thank you.

Dealer wanted $4800 + tax to do engine out to fix this exact issue on my 09 GTS. Weissach Vancouver quoted me $1500 + tax to fix it this way but using a rivet instead of the set screw. Imagine paying the dealer all that money to replace the coolant bridge only for the part to completely fail again. The guys on rennlist say that you aren't in the cayenne brotherhood until this happens to you and some sort of major coolant failure will happen on 100 out of 100 cayenne's. Porsche should have honestly just replaced the low coolant warning with a picture of $ signs.

great advice :)

[@vacbmw]

Yes. Perfect. As planned.

[@EdwardRichb52]

May I ask what type of epoxy you used?

[@vacbmw]

Edward Rich any brand is good. As long as it’s for metal.

Did this work for you guys as i think i have the same issues with my 2010 Panamera S same engine.

[@vacbmw]

Mark Brooks it’s been many months still perfect

[@Drumheros]

Did you have to remove the fuel pump to get access?

[@vacbmw]

Sorry too long ago to remember that detail

[@jblthree]

He removed the high pressure pump, but you don’t have to. I did have to remove the crash plate between the pump and the firewall, and the lower stud that supports the crash plate where the common rail inlet fuel line is secured to.

[@rickslick730]

How much do cost to have that done?

[@vacbmw]

Rick Smooth I don’t remember. Are you local?

@@vacbmw I live in Pleasantville NJ just out side of Atlantic City and just recently purchased a 2012 Cayenne Turbo with 83,000 miles so fare all go. But every time I pull off I feel something in the drive tran but clear up as I'm driving

[@vacbmw]

Rick Smooth I can’t help you unless you make the drive up to Philadelphia but that has nothing to do with the coolant leak this video is only for coolant leak issues

[@2568316]

Had to do the same at 27k miles. Now at 88k and no issues. Getting the electronics out of the way was a pita. Porsche should have addressed the issue!

@@vacbmw I found out what it was,the previous owner never change the Transfercase fluid I changed the fluid three times to c Flush it good and now the noise is gone and it's smoother and a little quicker

[@tolishel]

Yep, same thing happened to mine. I'm in in the process to do the repair. The wiring harness is in they way.. Need to move that on the side also :(

[@jblthree]

You only have to move the coil pack harness for that bank

[@luchio6675]

I think that just happened to me

[@E39M5SPEED]

Won’t hold. Long term.

[@Oldguynotbald]

I was going to say the same thing, but the set screw should hold it long term.
