wasting time and fuel to cooldown turbo in winter?

[phlfly]

So with my wife driving the passat 2012 TDI I am gong to have to get a gauge so she can monitor the temp of the turbo and train her to wait to shut down the car until its turbo temp has gone down to a safe number of degrees?
Not saying she can't do that but I can see her parked at work being on time but haveing to wait in her just about new car for the turbo to cool down and ends up being 5 minutes late because her new car was going through a regeneration when she got to work.

Maybe this is why our 2012 tdi passat with 9,000 miles is in the shop now waiting for a turbo to come from overseas? Not real excited about replacing turbos on a regular basis.
I am starting to think I should have kept the old TDI's as we had virtually no trouble with them and had high miles on them when we sold them.

I think you are going to crazy, scientific, it's much more robust now days, I had VW 1.8 T and sold to friend with 120000 and he drove another 50,000 miles and never had problem with turbo.

Very very unlikely that this is why your car is in the shop. As I've already mentioned in the turbo thread, I think your turbo problems are due to a failed sensor or another component that is tied into the turbocharger system.

It's really not that much of an inconvenience to monitor EGTs - the cars only regen every few hundred miles and chances are that it will do it on the highway. If you have a short commute and that's about all you do with the car, then yes, you will likely find yourself in the situation of the vehicle doing a regen when you arrive at the destination - that's just the way it is.

Of course nobody is forcing you to do any of this. Feel free to operate your machinery as you see fit. I think that frequently interrupted regens could reduce the overall life of the turbocharger by at least 50%... if you search the Sportwagen forum, it seems that there are quite a few turbo failures around the 100,000 mile mark (genuine turbo failures, not sensor issues).

A commonrail TDI is not your buddy's 1.8T. Feel free to operate your vehicle however you see fit, but don't spread misinformation and conjecture by comparing apples to oranges.

This bears repeating. Misinformation is very confusing to newbies and aggravates the oldtimers who have to clean up the aftermath.

So in order to monitor the regeneration she would need that scan gauge like in your video? or does the car tell you when the regeneration is going on?
My wife is driver of the car 99% of the time and she has done very good with the other TDI's We have had running them 200,000 miles without any major problems. I am sure if she has to she could monitor a add on gauge, let the regeneration complete and allow the turbo cool down.

 

[VeeDubTDI]

Unfortunately the car doesn't tell you - you will need a ScanGauge or other OBD monitoring device to read the EGT sensor.

We just need to hire us a TDI engineer for about 7 days... that way we can have all of these darn trivia questions answered once and for all!

After a week... wow. My set-up was $21 total (eBay+download).

 

[VeeDubTDI]

Yeah those are pretty sweet as long as you don't mind having a smartphone hooked up in your car all the time.

Tomo's setup in his Sportwagen is really sweet - EGT display in the driver's side air vent.

 

[JaredC01]

I do love the P3 gauge, but very much dislike only having one parameter at a time. I went with an UltraGauge probably a year ago now, and have been very happy with my purchase ever since... The only thing I dislike is that it doesn't read boost from the TDI, but it does read engine load in percent which gives me a decent indicator of what the turbo is doing.

Pretty much any OBDII reading setup you go with can read the "cat" temperature probe, which will let you know when there is a regen in process.

Well I spent like 5 years combine between bimmerfest, M3forum and 5series, and I tell you over maintenance is not good thing either. Also people come to forum to complain about the problem, and at least 50% of this people are laying, what did it lead to this problem for difference reasons. All these stuff is nonsense since VW/Audi/Porsche engineers spent years before released this car to production and if they could make it better with less warranty claims they would done it. Come one people be real. I'm aerospace engineer, and I tell you it could be problem along the time anyway, but the thousands engineers are trying make product better every year and be on reasonable price range. My advice just drive and enjoy, replace oil much often then recommended and you will be fine.

Just to reiterate what others have said, after 3-weeks of ownership and a week of running Torque Pro my experiences have been that EGT generally tends to be in safe range at time of parking, usually 400 or below. I do let it get to 375 or lower before shutting off, but that doesn't take long at all.

Yesterday, however, I had my first "active" regen take place when I parked at home after a relatively short drive. Temps were maintained between 850-900, so just left the car running. Took about 3-4 minutes before it finished and EGT quickly dropped to 450 and then below 400 within 30-seconds. Being a newbie to TDI it quickly became apparent HOW important it is to have an OBD2 gauge of some sort and to monitor the EGT temps before shutting down. Can't say I ever would have known a regen was taking place by the sounds prior to shutting down. Obviously, the typical diesel odor was far more apparent during the regen so perhaps if I was trained well enough to sense this to know a regen was happening a gauge would not be "necessary", but quite frankly it seems elementary to monitor temps. Almost so much so that VW should consider making these types of gauges a standard included option, but I'm sure that has been discussed ad nauseam on this forum in the past.

 

[VeeDubTDI]

Is love to see and EGT gauge from the factory. I'm sure VW has had plenty of meeting about these topics and they decided that too much information would scare some buyers away. A lot of people out there don't want to know anything about their cars and more information just confuses them.

 

[Papachristou]

you can tell if it is running a regen cycle by the idle. If it is running a regen, idle is about 1k instead of 900, i just circle the block and it is usually done.

 

[bhtooefr]

Really, VW should've somehow done a turbo timer.

It would've been easy to show on the cluster, "Engine will automatically shut down in x minutes" when the key goes off during a regen.

 

[Papachristou]

^ yeah i wondered why it doesnt show on the MFA when a regen cycle starts and then its estimated time to completion. Although we as TDI dorks would want that info, it may be too much for the average consumer. It could have at least been made an option in the MFA just like average or instant MPG tho.

Turbo timer is a waste since these itty bitty turbos dont get "that" hot. I used to a have a GT30 series turbo on my audi and it would get toasty. but even on that thing, as long as i drove easy on my last few miles before getting home, i would only have to let it idle about 30 seconds for it to get to normal EGTs

 

[bhtooefr]

Well, the "itty bitty turbo" is getting quite hot during a regen, and the ECU is holding it that hot, when you're sitting there idling, even.

So, the turbo timer wouldn't be so much to allow the turbo to cool down, but rather to keep the engine idling during regen and then allow some cool down.

 

[Papachristou]

i understand that it gets hot during a regen but a turbo timer isnt the solution unless it was linked to the regen cycle specifically. it really wouldnt be a turbo timer, just a factory setting then.

But you know in this attorney filled world, there is no way they could have a car that runs after the operator has left the car. you can just imagine all the lawsuits....

anyway, in 5k miles, ive only had two regens running when i got home, the first one, the fan ran and the other i learned to identify the regen cycle by the higher idle and just looped back around the block till it was done.

 

[bhtooefr]

Then lock the doors and the seat belt until the regen cycle is complete.

 

[Papachristou]

come on, people sue mcd's because they are fat. too big of a risk. i wouldnt do it if i was a big company.

 

[VeeDubTDI]

Not your conventional turbo timer that runs the engine for a pre-set amount of time after shutdown no matter what... that would be stupid and wasteful.

What tooef is proposing would be a turbo timer based on EGT that would continue to run the engine until the EGT is below a certain setpoint. This would take care of allowing a regen to complete as well as allowing the turbo to cool down if you happen to attempt a shut-down immediately after a spirited run on the highway.

You're never going to get a factory turbo timer out of Volkswagen, so you may as well wake up from that pipe dream now. You'll either need to pay attention to what your car is doing and take the appropriate steps yourself, install a turbo timer that will function based on EGT readings, or ignore it and take your chances.

I wonder if you could use the autostart so you would not have to baby sit the passat while the turbo is cooling off during a regeneration? you would need a gauge to monitor the temps. I know with my astrostart on my ford pickup when I need to leave the pickup running but want to get out and take the keys with me I hit the autostart while it is running and it will run for a pre programed time then shut down.

 

[Papachristou]

yeah i understand what he is saying but name one turbo car that comes with a timer of any kind installed from the factory? there isnt one i know of and probably for some liability or legal reason. It would be nice to at least know when a regen cycle is starting and its estimated time to completion on the dash.
