TURBO: 2012-2014 Passat turbo failures [discussion thread]

[wdb]

Thanks for the quick response. I'll check the ODB forum for a Mac-compatible scanner. Of note: Engine light is back on; hope that the ECU flash update would correct it dashed.

 

[EfinTDI]

A couple more failures showing in October, one in Canada.

I can't speak to the ECU flash as I haven't had one done on my 13. After my turbo blew the other week I ordered the ODBLink LX ( http://www.amazon.com/gp/product/B00H9S71LW/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 ) and I paid for Torque Pro (I think it was $4 on the play store). If you have an iPhone you will have to find a similar product to Torque. I set alarms for the entrance to the DPF (I think in Torque they call it Cat B1S1, but my VagCom calls it B1S2) and I can now tell when it goes into regen. I upgraded my VAGCom to the latest CAN bus version so I can do some stuff like take the hill hold off and reset the service light reminder.
If you do end up with Torque I can help you setup the parameters and alarms you'd like watch. I also have most of the Tasker programs to start and stop Torque when you get in the car and when you leave it. I am still adding some finishing touches but for the most part have it working pretty well.
As an aside, has anyone with torque noticed the stock "boost" reading in torque does not agree with the VW specific PID ( the one reported on 0x70h)?

You do know about the setting levels of hill hold, right? And other than a 2014 why do you need VCDS to reset service lights?

I like VCDS, but agree a laptop is a bit big and clunky for everyday use. Though some people post with big android tablets stuck on their dash. I think this will be a good idea to revisit my car computer idea.

No, I didn't know about that. I need to research it. I asked Ross-Tech about where the procedure is and they couldn't help me. If you have a link you can send me I would appreciate it.

Resetting the Service reminder is the immediate need. but also being able to calculate how much DEF is needed during regular services. I haven't researched it too much, but on my Jetta I needed it to do the timing belt, I am not sure if it's still needed for that with the Common Rail engines, so maybe I spent money I didn't need to, but I can also use it for my neighbors audi that has those electric rear brake calipers.

I still need to put my failure in the Database. Been almost 1500 miles since the turbo failed and was replaced.

NYTDIBoy: Good to hear that your turbo was replaced and after 1500 miles, all is well.
Did you get the entire exhaust system replaced at the same time? (I don't recall seeing an update to your original post...if you did, sorry I missed it...)

No, the DPF/CAT was replaced (as it's one unit) but nothing after that. I did notice that the first regen after I picked it back up had oil fumes coming out the tailpipe, it is also stained with burnt oil, but before the tailpipe still was nice and shiny. The intercooler and 2 glow plugs were replaced as well.

It actually came up in discussion here on TDIClub. I remember it because first thing I thought of was adjusting my wife's Beetle hill hold.

FWIW the level sensor in the AdBlue tank is not like a fuel level sensor. The ones I have looked at work much like a RV tank level gauge - IE:1/3 full, 2/3 full, full.

The CR TDI pump timing is not that critical. You basically just line up the pump pulses with injection events, so the pressure oscillations match up better with injector opening.

Its been a while so I'll confirm on the next Audi, but I never use a scan tool to retract the parking brake motors on Passats or Tiguans. Our instructor showed us a quick trick -unbolt the motor, push the piston back like a regular caliper(turn the drive lug while pressing the piston in), bolt the motor back on, cycle the parking brake.

Jason: "...parking brake motors..."? NMS Passats don't have them.

Correct. However, he is talking about NYTDIBoy's neighbor's Audi, which does have them.

Well crap! Had a customer's car towed in for "no crank, no start". Yup, starter is burnt up. Odd as I can count on one hand how many starters I have replaced in 10 years. Replaced the starter and it rattled to life for maybe 10 seconds then died. No crank/no start again and the starter is hot. Check the oil - nothing on the stick and smells burnt. Remove intake pipe -EUREKA! turbo shaft flopping like a wet noodle.

Customer called in (after we replaced the starter, but before we had a chance to contact them) to complain remote start has not worked in months. Soooo.... You drove the car, with a blown turbo, until it consumed all of its oil, then continued until the engine seized up. After that you cranked (attempted to crank) the engine until the starter failed.

Hmmm... Yup VW FOM authorized the full repair with new (not rebuilt) long block.

Oh boy....

It probably had a CEL and a flashing GPL... just like 99% of the other turbo failures out there. But, you know... warning lights are there to be ignored.

TURBO: 2012+ Passat turbo failures [discussion thread]

No MIL, DTC stored was starter mechanical blockage or electrical fault. The old starter felt rough when you tried to turn it.

So I guess this is a first for most people? She's naked!!

Sure does make the job of replacing a DPF and turbo easy.

Thanks for the pics!

 

[Herkguy]

Wow if I new I could have had a new engine I would have let the turbo blow and drive the heck out of it...lol

Yes thanks for the pics! How long does it take to pull the motor?

What a great time to upgrade the sway bar and sound proof the fire wall.

 

[SilverGhost]

Uh, we got lucky on the new engine. 99.99999% of the time it's all reman and in pieces that have to be assembled. There just happened to be new engine in our depot, no used available, and a field rep in the store that was able to authorize the job(and new vs reman parts).

We were expecting some push back from VW because the engine is damaged as well. But can't complain too much, as it pays decent.

Here is the new engine from "the fatherland"

It comes double bagged, absorbent mats and laying on its side. Now the fun begins transferring parts.

Don't install it in that Passat. Let me have it to put in my 07 Canyon! Just tell them that the engine "ran" away.

 

[c-wagen]

Well, the engines are made in Poland, but what the heck, is a new one! +1 to kjclow, that will improve the Canyon a lot!

 

[SilverGhost]

True, the security tape did say "Volkswagen Motors Polska"

I think I know why this engine stopped trying to run;

There is a tall shot worth of oil sitting on the valves of #2&#3 and #4 is wet. I would say 1-2 quarts drained out of the inter cooler.

I think I would want a simpler (ALH, AHU, etc.) for it to end up in my truck. This thing is like the engineers went drinking with Italians and threw several bowls of spaghetti at it.

Can't put an engine older than my truck in NC. Since the ruck is an 07, then I'm kind of stuck with a CR, if I insisted on putting in a VW motor.

 

[SilverGhost]

That sounds like the same smog rules as California.

...... This thing is like the engineers went drinking with Italians and threw several bowls of spaghetti at it.

That's the funniest analogy I've heard in a while

 

[SilverGhost]

It's not quite as funny when you're the one trying to remember where it all goes. But the other guys are having a good laugh.

So if someone hadn't told me to look, I probably wouldn't have found this right away. See how normal and un-damaged the turbine and compressor wheels look;

Bonus is both wheels were jammed at first so they didn't wobble. It took a little fiddling before the compressor wheel flopped over to one side. Then both slide in and out - broken shaft.

Jason

PS, it's taking longer to transfer parts between engines than to pull it out of the car.

Looks like a V500 -0005. What's the new one?

 

[jrm]

Hope the EA288 has less a few less plates of spaghetti

The EA288 is a giant vat of spaghetti.

 

[SilverGhost]

And they decided to throw in the pot as well. From what I have seen the EA288 will need to be removed or at least "loosen & fasten" for some of the jobs that are done in the car on current engines.

I saw 0020 on the new one. I'll try to remember to snap a picture before the engine goes back in today.

[oilhammer]

Got a BW turbo in here with the compressor rotor broke right in half, each one pulled neatly away from the shaft and wedged tightly into the housing.

Why is Volkswagen still using these things???

 

[SilverGhost]

Good question.…contracts maybe? Last I heard they wanted to quit making Routans but Fiat was holding them to their contract signed with Chrysler. Right now they are sold to corporate/fleet only.

This is extreme service position

It would start like this, but obviously the open cooling and Freon systems would be a concern.

Another thought crossed our minds while staring at this mess. The front HO2 sensor was wet, but the EGT was dry. There was little to no debris anywhere (just oil). I almost think we could have replaced just the turbo and cleaned the rest. The main arguing point was whether the rods were damaged?

It's a moot point now because the new stuff is all in there.
