*As much as I hate to recommend it, have you taken it to the dealer, in particular with respect to clutch slippage?
*Window regulator should also be covered under warranty.
*TPMS - you can reset. Have you done that at a low enough temp to keep it from alarming again?
*Radio - no idea. Do you use bluetooth for your phone? Does it function the same whether or not your phone is BT enabled?

Best wishes for the new year.

Radio going back to static is the "87.7 radio station bug". Talked about more than once here.
Torn CV boots - wow! Not sure what you're driving over, but that does seem bad.
Clutch slippage - that's not good. Take that in for sure.
Back-up camera in my car is the best of probably 20 different cars I've driven in - only time it doesn't work is if I put it in R, then go out of R to another gear, then back into R again.

I have been rather disappointed with the MK7 quality overall. My mk6 JSW with triple the miles was a more solid driving vehicle. I like the Ea288 engine more but the car itself feels inferior overall. Perhaps are I replace parts with non-OE pieces they will be superior quality but I have my doubts.
Does this happen to be the red one purchased from Hall VW this summer/fall? I was very interested, but when they started showing me pictures of it at the junkyard it came from... Its sad how some of these buybacks were treated.
Many of your gremlins could be cause by water damage/dry rot. My '15 GSW 6spd with 33k has only a squeak behind the dash to complain about. (had the peeling shift boot trim replaced the week after I bought it)
Best of luck to you. Do you have any kind of buy-back guarantee on it?

It would not surprise me if the clutch delay valve (restrictor) that's built into the bleeder unit could cause a slipping clutch after some miles.

FWIW, my MK7 has 75k miles and no crazy issues that weren't self inflicted.

It is a platinum grey originally from Michigan that was purchased in Minneapolis in sept 2017. It sat for a little while, 2 months, while it was in limbo being fixed but the CarFax shows a pretty quick turn around from VW buying it, fixing it and then selling it at auction.



None my issue are life ending, just very annoying.

I find I need to hold the window switch way longer than I should to initiate the auto up/down feature (1-2 seconds, where our previous MK5 and NMS it's instant), almost like there's lag in the canbus for it to register.

Default 2015 GSW with 6-sp DSG and push-button start: Spontaneously Dies

My 2015 GSW with DSG transmission and push-button start was "new" in 2017 when we bought it from the dealer after having part 1 of the settlement modifications complete. Still under original warranty. Car has about 18K miles on it.
The car has spontaneously died while driving 5 times in the past 1.8 years. The first couple times, I thought it was just a fluke, but the 3rd, 4th, and now 5th time I've taken it to the dealer.
Behavior: Driving steadily along with no issues. Suddenly the engine stops running. Cost to side of road. Car is still "on", but engine is not running. Glow plug indicator is on. Pressing the brake pedal and the start button, the car cranks quickly, but will not start even after 20 seconds of cranking. Foot off brake and push the "start" button so car is completely off. Depress brake and then the start button again and car starts immediately as if there were no issue.
No fault codes are set when this happens.
Repeat this behavior for failures 2, 3, and 4 over a period of about a year. Months and thousands of miles go by between occurrences. Dealer could find no issue after 3rd time. Dealer (at VW recommendation) re-downloaded the ECU firmware (same version) to see if that would remedy the issue.
5th occurrence happened 2-16-19 at highway speed and car coasted to side of freeway. After turning car off, the car started again immediately. Upon putting car in Drive, engine dies. Wait 1 minute. Car starts again, appears normal, but dies again after putting transmission back into drive. Car towed to dealer.
At dealer, car would not start at all. Dealer found the starting battery failed the performance test and replaced the battery under warranty. I think this is probably unrelated.
Dealer's has had the car for 3 days now attempting to reproduce the issue. It continues to behave normally since replacing the battery. Planning to speak to the VW rep tomorrow.
Anyone else had a MK7 TDI spontaneously die like this and leave no codes?
Jim

These cars do seem to be sensitive to good voltages from my reading. The battery and/or charging system may very well be the issue. Do you know if the battery was replaced with a new one when you bought it after being "stored". What kind of driving do you do? Lots of short trips or longer drives? Do you have access to VCDS to scan for codes yourself or are you taking the dealers word? Have you measured and/or tested the battery yourself at all?

Default 2015 GSW with 6-sp DSG and push-button start: Spontaneously Dies

Thanks for engaging LightFlyer.
Issue: 2015 GSW with 6-sp DSG and push-button start: Spontaneously Dies
Q: Do you know if the battery was replaced?
A: The battery was NOT originally replaced and was nearly 2 years old when we bought it.
Q: What kind of driving do you do?
A: Commuting. Mostly 45-60 minutes each morning and 45-60 minutes each evening. Should be more than enough tine for a battery to come back up to full capacity after starting.
Q: Do you have access to VCDS to scan for codes yourself
A: Yes, but have not used it related to this issue yet.
Q: are you taking the dealers word?
A: Yes, so far I have. They appear to be earnestly searching to diagnoose.
Q: Have you measured and/or tested the battery yourself at all?
A: No. I never suspected the battery. The dealer did replace the battery with a new one this week and they are hoping this solves it. However, this happened first about a year and a half ago when the battery was much younger and several times in between then and now. Until this latest time, the battery had enough power to crank quickly and immediately start the car.
Thanks again.
Jim

Maybe your battery was sulphated from the storage causing intermittent issues.

What Is Battery Sulfation?
Battery sulfation is the process of lead sulfate crystals building up on a battery cell. Sulfation will occur to some degree in every battery throughout its lifetime. However, rapid sulfation can occur with extended storage, overcharging, or undercharging of a battery. As more sulfate builds up on a battery cell, the less effective the battery becomes. Sulfation is the number one cause of early failures in lead-acid batteries, and can lead to any of the following: loss of cranking power, longer charging times, excessive heat build-up of your vehicle’s electrical system, shorter running times between charges, and ultimately shortening your battery’s life.

https://no.co/blog/diagnose-and-treat-battery-sulfation

Hopefully the new battery will fix this. I would suspect your car did have some codes and just not revealed to you for some reason. I thought replacing the battery was a requirement before sale of these cars. I scan my car every so often just to see if anything shows up. Sometimes intermittent issues will give you some warning before a complete failure happens.

Thank you for helping.

On a couple cars I have that sit for long periods, I keep them trickle-charged with BatteryMINDer chargers that tout their desulfator capabilities.

You think that the battery sulfation issue could cause a car that's driving along fine, with overall voltage controlled by the alternator/regulator to spontaneously die? Then start up again as if there were no issue?

I personally have no idea, but that site seems point that it might be a possible issue. Especially if swapping the battery out fixes it. Probably a possible reason why they were all supposed to get new batteries before being sold.

Maybe the battery hit a dead area and therefore transferred no charge. I don't know if these cars will run without the battery hooked up. I've heard that the older diesels could keep running if you disconnected the battery.
