2015 Passat TDI sudden loss of power (engine control malfunction)

Smashed Ixnay said:

Got my loaner. It’s a 2018 passat SE. I haven’t driven it much less, but it feels snappier than my wife’s old 2017 Passat SE that we had. I actually am kind of liking it. I tried finding the option to look at the mpg’s and I can’t find anything. It’s miles to empty, mph, and a few other things, but no mpg trip meter.

MPG is on the first screen when you go to car menu from what I remember.

Found it. Someone before me had the option turned off in the settings

Unless I missed it upstream, are you being billed for all this carnage, or is VW covering it under the "dieselgate" extended warranty?

Everything is being covered by VWoA. I looked at the paperwork when I sign for them and see the charges on the bill, which is what I assume VWoA is paying the dealer.

Good to hear. Supposedly unless it's a clear case of misuse, the settlement states that VW will step up to the plate and fix most all engine/emissions issues.
.
I've been very satisfied with the way VW has handled this fiasco. My '15 Passat is running fine after P2.

After the latest fix (04-06-2019) the car still isn't fixed! Same fault coming up. So almost 4 weeks now my car has been at the dealer.

It seems like they should pull out the entire power unit (engine, harnesses, control units, etc.), and give you a rebuilt/crated unit. Or, they need to put you in a new TDi.

The complexity of modern engines does not create unsolvable issues...but the solutions are limited by time and cost. After a month of troubleshooting and replacement work, with the problem still present, it is obvious that this one is beyond their troubleshooting capabilities.

Or, just keep driving the loaner and try to talk them into an extended warranty on the vehicle they've been working on. Something that'll take you well beyond the Dieselgate warranty.

I love VW TDI’s, but this car is a waste of money for VWOA, IMO. I mean, how much money are they going to keep dumping into this car before they realize it’s cheaper to make it go away? A new crate engine and the installation must be a fortune, but that would be nice to have.


I honestly prefer a buy back or new TDI. I think that would be the cheaper option long term.


Whether I keep this car or not, I’d still buy another TDI after this one. I just haven’t found another car that can give me great mpg’s, while enjoying driving it.

A new engine and installation would cost a fortune for us, but not VW.

New crate engine is not that expensive...for the manufacturer.

The install is pretty straightforward and would take far fewer hours than they've spent troubleshooting and attempting piecemeal (guess) fixes.

I'd ask for that...or a new vehicle.

Not any real update other than they still don’t know what is wrong with it. I’m trying to get VWoA to buy it back. I don’t trust the car at this point.

Wow..... unbelievable.

Supposedly it was a wire going to one of those DPF sensors, so when the replaced some wiring the second time, they apparently didn't go far enough.

Got the car back today and made it home without any issues. I will not celebrate until about a week of having the car, because I've had it before after they fixed it and issues popped back up.

I really hope my car is fixed, because driving this everyday is a pleasure compared to all the gassers I've driven since my vehicle has been down.

Your last post was a few months ago? How is the car now? Is it fixed? Still doing it? Was it covered under warranty?

Answered in your thread. Car has been working fine since they did this last fix.

Glad to hear that!
