Tandem pump failure would make it difficult to turn at low speeds IIRC. Also, I don't remember reading about such a large loss of oil in such a short time for this failure.

It would seem that it is an oil leak due to the loss of such a large amount of it, but there are literally so many places it could leak out of.

 

Well I have certainly noticed for the last few months a different feel from the steering at parking-lot & garage speeds. I would have previously described it as feeling the pump power pulses or a 'notchy' feeling. I had actually planned to check PS-fluid this weekend because it had gotten annoying. Color me completely unaware that a steering system might have been a leading indicator. I wonder what else is slowly going wrong. Too bad I like the truck so darn much!

Agree - there are a myriad of places that 4qts can go. Just seems goofy that none is on the garage floor nor dripping from the car. I will advise back to the forum once the dealer confirms the theory or indicates some other failure mode.

 

Well, your steering experience pretty much leads it to being a TP issue......unless of-course you are heaving separate steering and oil leak issues.

Hey

How does a fuel pump mounted on the back of the R/H bank cyl head cause you steering problems?
No doubt it is well documented to be a source of oil leaks ( i just got the gasket for mine) but to lose that much oil, and cause steering issues it would need to be basically just flopping about at the back of the engine, and it normally shows an oil leak on the ground.

Weird thing about the tandem pump.... I got into a very slow speed wreck in the snow a couple of years ago in my v-10 and slid in the ice into a curb hitting the side of the passenger side front wheel with all the weight and force of the car and busted up the front suspension and steering to the tune of $3000. But the odd part was that it caused the tandem pump to leak from that violent impact. It still occasionally drips a few drops in my garage. Safe to say i check my oil level a lot. But it seems ok as the amount of oil it leaks is minute. Its odd but somehow the jarring seamed to cause it to leak. If i do someday have to replace the tandem pump i for sure will have the intakes cleansed.

 

Well the dealer called and said "We can't find anything. There's nothing leaking and it's not smoking and it passed all inspections for the 100k service." So I told the service-writer to drive it home tonight and then back in tomorrow and see if the DPF-cycle was still excessive. If not - will chalk it up to a pure 1-off happening.

 

Well I would tend to agree that a cabin full of smoke is a cause-less event defines an implausible answer. Yes the #of qts of oil lost was documented; but they found zero evidence of where it went as described to me.

Ultimately from the warranty perspective I have done my due dilligence to document that it happened and that apparently there is no diagnosed cause. Assuming I pick it up tomorrow I will put the car on my own lift and go over with a fine tooth comb and see what I can spy with mine own eye. My expectation is that it will ultimately happen again, so I will just keep extra oil in bottles to get me out of any jamb.

 

RallyDog Racing...two things:

1) I believe we have the same issue with the oil leak.

2) It's nice to see another UrQuattro owner here!

I'm going to be in Texas for work from 07-11 JAN but don't know if it will be in the Houston area.


PM me if you'd like to meet for a beer and talk Audi Quattro and V10.....

 

Sure man - let's meet up for quattro-lies and VW-beers! If you make it down my way (North Houston suburb) we can take my 3B'd UrQ out. I'm happy to show it off, it will knock your socks off.

General Update: got the car back, dealer as stated before found zero issues. Performed the 100k full service which I annoyingly noticed does NOT include doing th air filters... So basically I had a $450 oil-change I guess. I am going to log the oil consumption to see if I can chart the change in level. I believe it is going somewhere, and previously oil-level was rock f'ing steady month after month after month.

 

How does a dealer find zero issues after your stated oil level/smoke in the cabin? Have you seen my pictures of my oil leak here?

Was the mechanic blind? Oil on a hot surface will leave evidence of a leak. I saw said evidence on my V10 at the turbo, the cat and dpf. Subframe was a mess as well....

 

I think the blind-mechanic question is rhetorical in nature. I paid for a service and was told no issues. When I see oil-level dropping again I will do my own investigation on my lift and make sure that I am happy to find the same lack of evidence.

Motor oil doesn't just go-away without reason - I've built enough engines to KNOW that is truth.

 

Been having a some sort of leak myself. Faint to medium smell of burnt oil emanating from the grill/wheelwell area after operation. Strong smell of burnt oil in the cabin after long drives >30 minutes. Seems to enter the cabin in cycles (may be related to the HVAC system pulling it in). I have noticed some notchiness in the steering - but I'm still confused how this relates to oil leaking. Anyways - subscribed.

 

Our 2007 with 52K has the same symptoms. It just had its oil changed at the dealer. Service at the dealer, Chapman, has been incredible. First they thought they were going to replace the turbo seal. I followed all the links about this subject and got great answers from the original posters. If this was out of warranty, I would get second opinions / and make sure the shop knows V10s. Seems there are several failure modes that can appear very similar.

 

this cant be the VW dealership in bellevue, wa. can it? cause they suck!

 

V10 Turbos

Chapman VW is taking great care of us. Their service writer is awesome. They replaced a pump that they suspected was the issue. They have now decided its is the turbo and their protocol is to replace both of the turbos. I was told VW is back-ordered on the turbos. They have given us a loaner Passat as well. I can't complain. I am going to have both turbo intakes removed and cleaned - they use a media blast. $500.00 bucks.. I think we should do it. Scott said most V10's should have their turbos cleaned at 100k.
I just need to get my wife to drive much faster!

Any other issues I should check before they install the turbos and replace the motor?

Update: I've put another 500 miles on the 'Tag since the first happening. I had a second bout of the same smokiness 50miles into the new tank of fuel, but 200 miles later still no 3rd happening. There's a distinct burning parafan/wax smell to the smoke which really points me at engine-oil vs. other fluids.

Note for those of you with this issue, as soon as you get your first whiff/puff - put the HVAC into full recirc mode and you'll not go full-on Jeff Spicoli hot-box on the interior of your car.

I guess now that I've added to the garage I can take the time to pull the manifolds off the 'Tag and see what's really going on in there. Definitely right-front area, and I see lots of grime/build up around what looks to be PCV hosing on the pass-side valve cover where the hose passes through it. Pardon my gratiuitous posting of a pic of my new pride & joy... At least there's a 'Tag tailight in the photo....

 

911 looks great, love the latest body style...usually take a few years for every facelift to grow on me.

 

Lovely.. Maybe it's time to sell my V10. I was at the range last night sighting in something that goes bang and got in the car to drive home. First mile no problem everything working per norm.

Then I went to set the Cruise Control and it turned on but wouldn't set no matter what I did. I wondered if one of the safety switches on the brake pedal had failed when I came to a stop sign. Stopped per normal. Put my foot back on accelerator pedal and the car took off with less vigor. Then upon continued accel-demand it was a LOT less vigor. WTF??

I confirmed all temps are good. Confirmed no idiot lights, no CEL. Couple stop signs later - I decide I've got zero boost. I wondered at a shutdown/reboot of the car but figured I would get home before trying diagnostics. It drove home with nary a chirp/complaint/indication that anything was amiss outside of feeling exactly like an old non-turbo diesel. Thank god it at least has 10cyls and 5.0L of displacement - because it will move the truck when you have no boost; just not like we're accustomed to.

I put it to bed wondering at the logic of the VW-gods to afflict my v10 with issues moments after the 911 comes home to roost. I mean VW owns Porsche so gods are truly being spiteful. Even my old Audi silently laughed from the 3rd bay and mocked me by a slow-cranking indicating a run-down battery.

I fired it up this am and put VagCom on it. Pulled all codes. I had a single-instance of Turbo Control Module failure. Occurence count 1. So finding nothing else wrong - I cleared the code and it hasn't returned yet on this AM's test drive. I can happily report the cruise-control is back to operational as well.

What is the wisdom of the V10'ers out there - is this the harbinger of new-turbos looming on the horizon? Is it time for me to trade the truck away and go F-250 or Ram-2500 before I get whacked with a major major repair?

I welcome the input.

 

Interesting. I have had the same thing happen twice now. Zero turbo boost, the indi shop I took it to also confirmed that there was a fault in the turbo controller.

Still experiencing intermittent burning oil smell. Trying to hold off service until 75k service.

 

This all sounds so terrible. I experienced the same issue just last weekend. Admittedly I've been using the manual shifting program to enjoy the big torque at low rpm. I thought maybe that over loaded the tranny or something, but after reading all this, it seems like I have the same Tandem Pump problem. Will bring it in to ismotors.com tmrw along with my 2 more years of extended warranty. Yikes!

 

Sounds like a blocked DPF to me.
