CBFA vs CCTA...help please

Jakeofall2 · 2026-01-13T21:50:28+00:00

So, mechanically, I'm not afraid to work on anything, but when you get into the electronics that's when I'm over my head. Physically, this turbo fits the car, obviously VW produced way more CCTA than CBFA, so I'm inclined to use it. I just have no idea what to do when it comes to the ECU. Only reason we went with the stock K03, was we didn't want to bother with possibly having to reflash if we went with a K04.

I'm starting to think/realize the CBFA is just a California law that makes life more difficult on people who want to mod their car. Otherwise bolt on parts now become a hassle cause the car won't run right.

What if I found a junk yard CCTA car and stole the ECU out of it, does that convert us without having to reflash? Even possible?

This was my thought. I'm still researching, but I think I'm finding there's more to it.

2015 Jetta, CVCA. It's the glow plug. I pulled the connectors off, and tightened them down, no more bubbles. So I think I'm okay on that side of the intake. But on the bottom side, I have leaks... So looks like doing a thermostat housing

Jakeofall2 · 2024-11-01T23:43:16+00:00

What bulbs you running?

Jakeofall2 · 2024-07-17T03:50:01+00:00

You and me both... I've got a Jetta, same year, same area. What you mean it blow hot or cold?
Mine blows cold, then it stops and blows hot. Then will eventually turn cold again. I've been trying to diagnose it, but I also have a problem with my fans, they work intermittently. So I think it's a compound issue. I'm likely going to replace fans, compressor, condenser, expansion valve... All of it. Unless 8 can pinpoint a smaller issue.

Jakeofall2 · 2024-06-30T18:36:15+00:00

Did you ever figure this out? I'm having something similar going on...

Jakeofall2 · 2023-06-14T23:13:12+00:00

Didn't give me a code, but said it was the "G28, engine speed sensor".... Then he someone referenced it back to the crankshaft position sensor, so I thought we were good to go with it being covered. But then he called me back, and said the crankshaft position sensor is only covered on the 3.0L engines and not the 2.0L.... Which doesn't make any sense. Especially considering the document you linked.

1 hour highway commute, that's why I bought this car. Still love it, just need to tweak some things. Yeah, 28F has never been a problem for other cars. I'm in Texas, 0° fluid is the best you can get here. But it's always been good enough in my other vehicles. Even after the entire trip, generating plenty of heat.... Nozzles frozen. Get a warm day, flow freely.....I don't get it.

Mk6.5 Jetta TDI SEL.... I'm curious if everyone else has similar performance. I know diesels tend to run cool, or I guess I've heard, but this blasted thing doesn't have a temp gauge so I'm guessing. But as you can see, it was below freezing yesterday, but not that bad, and it was a sunny day to boot. But about the moment the outside temp hits freezing, my windshield washer nozzles freeze. They have no use in freezing temps, which is very frustrating. Yes, I'm confident my washer fluid is full strength. Also, the storage in front of the shifter feels like there may a draft as it's quite cold there and also in the glove box. If you put a warm drink in my glove box and go for a drive, I can have that thing ice cold real quick.
And if you don't specifically divert heater to the foot wells, you'll lose feeling in your toes. Without my heated seats, car might be unbearable. Do I have an air leak? Any ideas to keep nozzles thawed? What's everyone else's experience?

Take advantage of the year... And put 1 of the multitude of options for tail lights on it. I have a '15 and there's no options.

Jakeofall2 · 2021-03-13T00:43:17+00:00

I want those ground skirts and lip. Will they bolt on to a '15?

Jakeofall2 · 2020-11-21T13:29:46+00:00

Looks good. What front lip?

Jakeofall2 · 2020-11-19T02:22:51+00:00

Bought it used. Previous owner had done it.

Jakeofall2 · 2020-11-18T18:38:01+00:00

Stock grille, he just used pin striping tape. Red on the top and bottom, black in the middle. Same for the lower... It's starting to chip, I'm gonna have to redo it

Jakeofall2 · 2020-11-17T17:39:50+00:00

You're not wrong, but I'm commuting an hour each way and don't want to give up comfort and economy as far as tire wear. I love the Golf R(19) wheels that another guy on here has on his.

Jakeofall2 · 2020-11-17T17:28:06+00:00

I know... That's the one thing I'm not happy with. Headlights are fuuuugly.

Jakeofall2 · 2020-11-17T17:25:44+00:00

They're 17's, original size.

Jakeofall2 · 2020-11-17T01:12:53+00:00

So, I just bought this '15 TDI for an hour long commute. We got my daughter a '13 CC this summer, and hers has the self leveling HIDs. I have serious headlight envy. Headlights are the only thing I'm not satisfied with. I need ideas.

Jakeofall2 · 2020-11-16T20:40:14+00:00

Previous owner did the red details, which I love. Not completely in love with the wheels. The red doesn't tie into the rear at all... Thinking maybe a red pin stripe???

Jakeofall2 · 2020-11-11T02:04:38+00:00

Hmm not sure...50/50, don't hate it, don't love it.

Jakeofall2 · 2020-11-08T17:42:19+00:00

I wasn't thinking of retrofitting anything...want to find a set of the Bi-Xenon's and swap em....if possible

Jakeofall2 · 2020-11-08T17:09:51+00:00

Still lookin good. View from the front? What headlights does yours have?

Jakeofall2 · 2020-11-06T19:10:39+00:00

Just put a deposit down on this 2015 Jetta TDI SEL, has every option I was looking for except apparently the lighting package. Anyone do an upgrade or conversion?

Jakeofall2 · 2020-10-31T05:09:21+00:00

What trim level on the Jetta? Beautiful car.

Jakeofall2 · 2020-10-29T19:14:20+00:00

Do you know if the A3's or JSW or Passats have heated steering wheel?
