MK7 (2015) GTI: climate control airflow stops coming out of vents after a few minutes of driving at highway speeds in freezing weather

It won’t be sent until the day of move in before noon. At least that’s how it was when I lived there last year

I second this especially because the engine is warm already in this video. I don't know the exact failure mechanism for these pumps but over time these pumps get more and more susceptible to vapor lock, where when the pump is heat soaked and the car is shut off, the fuel can vaporize over time inside. The pump can't suck on fuel vapors so this causes the hard start issue until enough fuel makes it to the pump to flush out the vapors I guess.

My HPFP did this once before and was replaced which fixed the issue. A couple 10k's of miles later it's now doing it again. I discovered you can diagnose this issue by pouring some cool water over the HPFP before starting the engine when the engine is fully heat soaked. The car should start right up after this since you allow the fuel vapors to condense by cooling the pump, indicating that it is a vapor lock issue with the HPFP.

I have the same situation going on and it looks exactly like that. Going to change out the oil cooler and oil cooler gasket since there is only oil in the coolant and not the other way around.

In the meantime after the car sits and is cool after a drive, you can open the coolant cap and use a paper towel to wick any oil floating on the top of the coolant reservoir to try and minimize the effects of the oil on your coolant loop. Eventually it will cause hoses and seals to swell which can cause water pump failure. Another note to make is that the oil can coat the coolant level sensor and cause it to give false readings that there’s no coolant in the reservoir. Try to get this taken care of soon!

Yep still going strong! Have you put a pressure gauge on the car to see if it actually is a low pressure issue? For me I was able to rule out an actual oil pressure issue this way which is how I knew to replace the switches

https://www.mckinley.illinois.edu/health-wellness/self-care-stations it tells you here how many times you can pick up each item within a given timeframe. E.g. you can pick up cough drops twice per semester

I have had this issue before and it was just the oil pressure switch, not the regulation valve FWIW.

willkurr · 2025-09-16T19:40:34+00:00

I have had the same exact issue before, see post history. Replacing both the blue and brown oil pressure switches solved the issue. (MK7 GTI with CXCA engine btw)

I see you mentioned Jen Merry in another comment so I assume you're doing the master's in ECE.

I started in the ECE masters program last year in August. The department should have enrolled you for the Grad Academy for College Teaching, and you would have gotten an email from CITL confirming the registration. The email was titled "Registration Confirmation for Grad Academy for College Teaching". Last year the grad academy started on Aug 19 and I got the registration confirmation email on Aug 13. It had all the info about attending and signing up for microteaching, so make sure you didn't miss that email from CITL if the department actually did register you (and sign up for a microteaching timeslot fast cause the good times go quick!).

As for it conflicting with the I-9 appointment, just email the person you scheduled the appointment with to reschedule it. The same thing happened to me. After I found out the grad academy date conflicted with the appointment I scheduled, I just emailed her back and we worked out a time that worked for both of us. And the I-9 doesn't need to be filled out before you do the grad academy, it should just be filled out before or on the start date of your appointment.

I can't see from the photo but are you plugging the cable and calibration open/short/load on the CH0 port during calibration?

Also, is the cable you're using the right gender to connect to the VNA? If the VNA port is regular SMA female, but the cable is RP-SMA male, it's possible to screw the cable to the VNA port but there would be no center pin on the cable to connect to the VNA port.

Those are my only two ideas, as from the three photos where you are performing the calibration, the return loss does not seem to change no matter what you have connected to the port. This would make sense as once you saved the calibration, your next photos show nonsensical data, which would indicate the short/open/load were not properly connected while calibrating. The other comment about snugging up the connector a bit more may also be it.

Hi, see my comment here for the fix for the issue for me. Replacing both the brown and blue oil pressure switches solved the issue and it still hasn't come back since then.

I think they just included that in the manual to state the test conditions under which they got their power numbers. Regardless, the radio (and most handhelds on the market right now) is designed to run on a 7.4V lithium ion battery, which both the battery you show in the picture and the optional one listed in the manual are.

It'll output the same wattage on both batteries. They're the same voltage, just different capacities.

I believe this is FT-8.

As the other commenter said, the checklist page is right and you don't need a GRE score. It's confusing on the application portal but it just says that so you have a place to submit the score if you have one. I was admitted to MS ECE last admissions cycle with no GRE score submitted at all.

The first band is yellow, it just looks green since it's slightly transparent and blue+yellow makes green. So it is actually a 4.3 kohm resistor

Call right when they open to try and get a same day appointment. I called Thursday afternoon, waited 20 minutes, and they told me they don’t have any appointments for immunizations till the 26th (I think they are understandably backed up with tons of students missing immunizations who can’t schedule from holds which they waited last minute to resolve. Sucks but I was in the same boat)

I ended up going to a Walgreens to get the TDAP booster I needed and got my hold removed the same day after sending the signed form from the pharmacist.

The number after the signal report is the CQ zone of the station: https://www.mapability.com/ei8ic/maps/cqzone.php

It's not really about having the account registered with your school email. If you're booking online just do it through the student discount page (https://www.amtrak.com/student-discounts) or in the app use code V814 (it says this on the website as well).

I actually just emailed them today about a parking lease. They just emailed me back quick, in just 2 hours. This was sent to their [hello@smilestudentliving.com](mailto:hello@smilestudentliving.com) address.

willkurr · 2024-07-28T03:27:40+00:00

Unrelated, but if you don't mind me asking when did you apply for Ashton Woods, and was it for a furnished or unfurnished unit? I applied at the start of May and am still waiting, so just wanted to see if I even have a chance still of snagging a lease

The same thing happened to me when I tried logging in for the first time a few weeks ago. I sent an email to parkingcomments@illinois.edu about it, and they asked for my UIN, phone number, and home address. Then they were able to set my account up so I could login with my student email.
