this seems like a different issue now isn't it? More like a bad connection with the battery terminals? At least that's what I'm interpreting the "8521278 Battery terminal recognition" to be. But I could be wrong.

Same symptom as before? Heavy steering and is fine after a restart?
Low low voltage error for steering rack?

I would think that a battery terminal error would cause more problems than just steering.

I could only find one reference to the error online. Has both of your errors in the scans. But he is actually talking about the intake manifold.

Lucky that was an easy fix.

Unless it came back, 2 posts above yours he said it was corrosion on the battery terminals.

Hey guys, sorry to wake this from the dead but I have a "15 GTI and I am having a similar issue. My steering gets heavy after driving for a bit, can be 20 minutes, can be an hour +, seems like the more steering I have to do, the sooner it happens. I have only one fault code - --1048836 Blower Output Reduction due to Energy Management B10CE 00 [009] - It seems to happen more often if I am running a lot of electrical load like fog lights, seat heater, rear defrost etc. I have noticed that my A/C fan will decrease speed to 3 regardless of a higher setting if the steering is heavy, sometimes it even slows down before the steering gets heavy. I had the dealer look at it in October right before my CPO ran out as it started acting up in August/September but was very intermittent. They found the battery was not completely bad but needed to be replaced. The battery was about 2 years old. It was fine for a couple weeks after the new battery but now I can make it happen almost every time I drive the car if I want. Another thing that is curious to me is that I had my alternator go bad about a year ago so that has been replaced. Is this an issue with the EPS, either bad CU or the motor drawing too many amps, or is it a power supply issue? Power supply seems like it would be okay as I have 1 year old alternator and a 2 month old battery but I have seen new parts fail right out of the box. I have never seen a warning light and everything works fine after an ignition cycle. I am going back to the dealership next week so they can look at. I will update this with any new information I have.

The gent above had the same issue and it was corrosion of battery terminals. So your could be similar.
Did you do the scan before shutting the engine off? That was the only way i would see the low voltage error as it cleared after a restart.
Who replaced the alternator? Just wondering if there is a special procedure to follow after replacing. You don't have a BEM do you? As that would need resetting if you did.

Always surprised to learn about all of the dumb issues a failing/ failed battery can cause in these cars.

Battery terminals are fine, failed to mention that. All work was done by a VW dealership, never had any issues with their work so I would think repair procedures were followed. I have worked in the car business with German(Porsche, Audi, and MB) for almost 13 years so I know what’s needed for repairs as far as reprogramming and the like. I’m not a technician but I know my way around under the hood.

When I have scanned for codes, I haven’t cleared anything just because I don’t want to erase any data like time stamps in case it can help the dealer. I can’t see when the fault was set so I don’t know if it’s current.

Merry Christmas and Happy New Year's to all. So the dealership found the alternator was not producing enough power, especially when hot. It was fine right after startup but after about 20-30 minutes, as the temp in the engine bay rose, the voltage level started dropping. It was a year and 2 months old. The CPO warranty expired at the end of October as well. My advisor contacted VW and got the bill mostly covered by goodwill. I have been driving it back and forth an hour at a time for a work jobsite for almost 2 weeks now and no issues. Hopefully this alternator lasts for a bit longer than the others.

I too am still haunted by this. I got an AGM battery recently just because the Varta in my car was over 2 years old but I still have the steering issue randomly. I also have a random issue with the A/C blower speed where it will only go to 3 even if it set higher. I am really wondering if it is the rack but I can be on the highway cruising for 40 minutes not using the power assist much at all and the fan speed will lower all of a sudden. It seems to be random but will only happen after 10-15 minutes of driving. Sometimes both steering and A/C blower will act up and or it is one or the other. I can live with it but it don't really want to but I also don't want to spend a lot of money trying to figure out the problem.

Pulled codes?

Pulled codes?

The only code I've ever seen was this - 1048836 - Blower Output Reduction due to Energy Management B10CE 00 [008] - . My issues returned a couple weeks after the alternator was replaced for the 2nd time. No steering warning light or any other warning lights ever. Car runs fine otherwise.
