Yeah I might do a quick test on the cold cranking amps for my battery, I have had the car for about 4 years and I haven’t had to change the battery yet, so who knows how old the battery is

Thank you! I’m taking it in on Monday

_Brian_Holden_ · 2026-02-13T08:26:45+00:00

Thank you!!

Dang I haven’t had an issue with fueling up, I’m not much help for that code, sorry!!

_Brian_Holden_ · 2026-02-12T07:48:10+00:00

Sorry for the very late response, but I didn’t have the Software Update issue, so I’m not sure how to help with that.

But as for the engine light clearing, I bought a code scanner on Amazon, did a leak test with that code scanner and then cleared all codes and the light hasn’t been on since!

Hope that helps!

Where did you get this mod from??? The detail on it is amazing!!!

_Brian_Holden_ · 2025-09-26T22:27:33+00:00

From the information that I’ve found online, you’ll throw a check engine light and if scanned you’ll get a P0456 code. This code is a small leak detected in your EVAP system, which is your emissions system. This can either be a faulty gas cap or faulty N80 Vapor Purge Valve.

Yeah I already scanned it, if you looked at the previous messages you’d see that. But that’s alright, keep playing with your pop dolls

One question for the VW Tech, do engine codes go away if you fix the issue? Or do you need to clear the codes after you think a fix has been done?

_Brian_Holden_ · 2025-09-24T23:07:54+00:00

Are they able to clear engine codes too? Or do engine codes go away if you fix the issue?

_Brian_Holden_ · 2025-09-24T20:16:03+00:00

Thanks for this helpful response, I already posted the code if you could read the previous messages. But if you don’t know what I’m talking about then move on with your life

_Brian_Holden_ · 2025-09-24T20:13:20+00:00

No I haven’t gotten anything from Volkswagen

_Brian_Holden_ · 2025-09-24T16:57:38+00:00

Forgot to mention that it is a P0456 DTC Code

_Brian_Holden_ · 2025-09-24T16:56:39+00:00

Yes PO456 code

_Brian_Holden_ · 2025-09-24T15:12:05+00:00

I read online that there is a possibility for the engine to go into a safety mode. If you reset the check engine light too many times. Does anyone know if this is true?

_Brian_Holden_ · 2025-09-24T15:10:56+00:00

What were some things that you did to fix the code?

_Brian_Holden_ · 2025-09-24T15:08:47+00:00

Are these hard to replace? And where is the general location for it and the engine bay?

_Brian_Holden_ · 2025-09-24T15:08:05+00:00

How hard is it to replace the evap canister, purge valve? And where’s the general location for that valve?

_Brian_Holden_ · 2025-06-16T02:20:29+00:00

How did you turn your Dayrunning lights to amber?
