2.0T Class Action for Blown Engines

[rowlands57]

My 2016 2.0T Quattro engine just died due to a severe loss of compression on cylinder 4. Time for a replacement as the car is in great shape otherwise. I maintained this car extremely well and I am still stunned that the engine died with just 104K miles.

Reading up further on this I have seen that I am not alone and it's almost random as to which vehicle this happens to, lucky me.

Anyway, I also have see that there may be a class action suit on this particular engine. Does anyone here have any more info about this as I'd like to join in and try to recover some of the major loss I am about to incur.

Thanks and I'll update here on how this goes as my mechanic is looking for a gently used engine at the moment.

I googled it and came up with this:

Thank you I had also found those and I'll be following the news to see if and when that may settle. If the first one does settle I'll see about getting in a claim. To say this sucks is putting it mildly as a 'new' engine may be no guarantee that it won't happen again. Until this happened I had no clue this engine could be a ticking time bomb,

It was posted about here what causes the pistons to go bad...

My car was never even close to being 'pushed', much less tuned. I'm just a pretty normal driver who enjoys the kick the 2.0 had getting on and off highways etc.... This car should never have puked this soon. I do appreciate the info though and will keep everyone here posted as this saga plays out. I'm really wondering if there will ever be another Audi in my future. I still miss my '04 A4 1.8T Quattro with the 6-speed manual. That's the car that sold me on Audi in the first place, this one not so much.

I know what ya mean!

I had a blown motor too but I had an IE tune on it and I think that was the main culprit. The IE tune pulls back the safety measures for knock so far to make their power that it meant that a spell of bad gas or excessive LSPI could pop the motor which is exactly what happened.

Not to mention these motors are very susceptible to LSPI. Calcium content in oils is also a big contributor. I had liquimoly in the motor at the time which is a higher calcium content oil depending on the variant. I dont recall which one I was using other than it being a 5w-40. I have since switched to Motul and wont ever use another oil in the S3 and probably stick with them for all DI engines in my future. They are the oil race cars use, most race cars these days are DI and in extreme conditions where LSPI and other engine related knocking events would occur.

In racing, you often don't use street oils which have various additive packages for anti-corrosion and whatnot which are not lubricants (some do, or at least do for advertising purposes). In racing, you want all the lubricant you can get and the best high temp performance possible and don't care about low temp performance etc. I usually use Redline race oils in the race cars, and Motul on the street. ECU manages load for LSPI, and its "Lugging" the engine, but with DSG, that shouldn't be possible. If tune allows that kind of load chasing numbers, shame on them.

Turbo boosted motors require correct fueling. Its extremly important!

Especially as boost psi climbs...fueling keeps the motor alive!

All too often a fueling problem will occur and the driver doesnt notice or recognize it and continues to push boost thinking it will clear itself(?).

I read posts here of issues under boost and fueling is often never even considered the issue.

DSG wouldn't shift was my clue. I stopped pushing boost until the issue was resolved.

On my 2015 S3 the issue turned out to be two bad injectors! No CEL.

My 2015 injectors were L version. The newest AK.

Found my valves seriously carbon coated.

Cleaned valves replaced all 4 injectors and the S3 has ran wonderful ever since! Zero issues.

First update. Replacement engine found and it has less than 50K so at least that's good news. We are going over the new one prior to install to do anything now that will save $ down the road. The thermostat/water pump comes to mind. Anyway this is still looking to be about an 8 grand job once all is said and done.

Since the car is in such great shape otherwise I guess it's worth it as coming close to replacing this would be a lot more. Still not at all happy with the situation, but I'll make the best of it.

I did injectors, upgraded to the B9 2.0t PCV plate and added a catchcan when I did my motor over.

Thanks for that advice, I appreciate it.

Well got the car back. New engine with 21K miles installed and all appears to be OK after a day or two of tooling around.

The first engine sent had 56K and was 'suspect' on arrival. It had a metal oil pan and the mechanic suspected something was up and perhaps it had been hit underneath. Took the pan off and found some shavings akin to what you'd see on a transmission or diff magnetic drain plug. That one went back and the new one was located, came in nice and clean and was updated with the new injectors. A few oil flushes later, just as a precaution, and I have it back.

I'm glad it's back on the road as it's basically a sound car otherwise and I don't feel like shopping for one in the current environment. I guess I'll stretch a few more years out of it and see what I feel like once the time comes. All in it was just shy of $8,500. It hurts, but not as much as throwing this one away and starting from scratch.
