Tune Reliability

[davek2787]

Hey All,

So I have a 2016 s3 prestige. I have a little over 3k miles on it at this point. Getting bored with the performance. I know the risks involved with tuning. That being said, i wanted to know if you guys have had any reliability issues after tune. Have any of you put a lot of miles on since 15k plus. Trying to weigh out all my options. Im leaning towards eurodyne but still not quite sure. So any help is very much appreciated.

I think this platform has proven to be fairly stout so far (knocks on wood) - aside from some early turbo manufacturing defects (which likely would have surfaced by now if you're at 3K), there aren't many tales of catastrophic failure with any tune or major increase in output that I can recall...if anyone driving a tuned S3 has had a major engine failure, they haven't announced it on this or any other forum that I've seen. (I say S3 because there are significant mechanical engine differences between it and the A3/GTi)

APR beat the crap out of their S3 torture testing the stage 3 kit, pushing as high as 550HP on the stock engine, something like 25+ dyno runs at that power level without a failure.

I've been tuned since 2K miles, APR stage 1 initially, went APR stage 2 around 7K miles I think? Almost a year ago exactly that I went stage 2. I'm at 17K miles now and have had the car a year and a half. It only gets driven on the weekends but I give it a good flogging probably once every time I'm in it, so far no problems, not a single unscheduled service visit; just regular maintenance. (vigorously knocking on wood)

Depending on how far you push the car, you'll see an increase in wear on the DSG and clutch packs for sure. I flushed and replaced my DSG fluid at 16K miles as it was starting to smell burnt after a hard drive and the factory "crispness" wasn't there, after the flush it was like new again. Meaning around 400lb/tq+, you're probably best flushing the DSG every 15-20K miles instead of every 35K, a lot of that depends on climate and driving style too. Outside of that, no downsides so far for me.

The cars that actually have problems are far and few between. Those that usually have issues after being tuned are likely speeding up a failure that was going to happen anyways. With that being said, the majority of the cars we have tunes have on average had under 1,000 miles when tuned. We have cars with only 7k miles on them stage 3+. If you are aware of the risks than I say you have yourself a good time and buy the tune of your choice. We highly recommend APR because the amount of development time put into this platform and their customer service and out of the box performance is pretty hard to beat.

Let us know if you have any questions.

Thanks,

Greg
