i am just a bit confused because my general understanding is the Cayenne and Touareg pumps are the same.

now when searching for parts a read the Touareg pumps have 4 bar and the Cayennne have 6 bar

I mean 6 bar. Sorry

Will you replace all this other stuff too?

Thats a good price, about the specs i am wondering. Checking the VDO it says 6 PSI.

Lewis how much you pay for your pump? AS i remember the Touareg is using the same. Its about 85 Eur.

By the way, somebody knew how much pressure / bar they deliver and how much Liter per hour? Thank you

The thing that had me fooled was my PIG would drive fine for about an hour until the pump warmed up then it was start acting crazy upon accel cutting in and out and such so it can appear as If your pump is running correctly when it's not 

Thats why experts say we have to avoid driving on high RPM with a low fuel level. Fuel is cooling the pumps. Low fuel level, higher temps and stress for the pumps.

Lewis cant tell you for shure. I took the car and same day my wife took it to drive to prague. I will have some testdrive when she will be back

on the way home from the shop i couldnt feel any problems. Strange . But i was so used to this vibration that i dont even remember how this  car usually is driving.

So was the damaged flex disk changed when you had the shaft replaced recently?

Here's a video of my own engine - currently being rebuilt after 130K. you'll notice that after the SAI pumps shut off the light knock becomes audible. From inside the car you don't hear it at all. Ambient temps were mid to high 30's at the time. What precipitated this finding was a low oil light following which I opened the hood to find oil everywhere and oil some oil in the coolant - looks like it just happened. Seems the oil cooler failed and the fan was spraying oil everywhere & I had no idea until the light came on. Add insult to injury, further tear down revealed the Y-pipe had not just cracked but was broken so major leak there and also the check valve adjacent to the AOS on the left bank was also cracked. Mind you now check engine light during any of this. At this point I told the tech to just change all the breather lines and vacuum lines while he was in there. Before doing this though he did pull the valve covers (I seem to change the gaskets every 2-years anyway) and no damage to the top end was found so definitely a bottom end issue. My tech advised he doubts it's a bearing issue because the engine still runs strong and compression was good all around when he checked, just the knock. I'll keep ya posted.

Sound like my engine. I would say very clear to hear the piston slap.

My engine started with a very light ticking. Everybody thought a lifter noise or from injectors. Over time it developed to a very loud knocking. Sounds not nice. Like a loud old diesel engine

Here is this little bastard

Just took my car from the shop. Take it there because i had vibration and was thinking the new cardan shaft from last year could be the reason.  It was only the flex disc. Thanks god. Drove now 25 km home. Feels good. 

I will bite my *** if all my searching in the engine compartment looking for the vibration was not the engine, was the cardan. We will see

I got my car back. I was told by my shop the cardsn shaft is ok, the flex disc was destroyed.

This is how the plug from the damaged cylinder looks like after several hundred kilometers. 

They will do tomorrow

Good business

This is about 80 EUR. Cant believe thats true. The original part from Porsche is something like 635 EUR

Shop called me today. Only the flex disc is gone. Rest is good. Service guy told me he changed and testdrive feels very good

Bosch 212 is the best offer i found. Delivery 3 / 4 days

Bosch 260 EUR i found 

Lewis i will check now

Audi looks not good. Strong hit. Be happy nothing serious happend.

Actually i cant tell you exactly. I believe it was in there for some thousands. I dont now if it became so bad over the time or just in the last couple of weeks.   I will check the new one which i put in these days.  You will see how a plug looks after just some kilometers

Check the plugs. Here you have one.

i have a first generation cayenne s which has a scored cylinder no. 6. i just replaced the plug because it wasnt working anymore. No wonder
