2019 SE with 6500 miles throwing codes for the turbo.. help (attached log from obd11)

[Blindeye_03]

My EPC light illuminates on the gauge cluster and my infotainment says the start/stop isnt working right. Then I see on the performance page that I have 0 boost pressure and the car is slow as hell.. I managed to reset the codes tonight but if i take it to VW with no EPC light can they still pull the codes and fix my car? Or do I need to drive it in limping with no boost?

I am COMPLETELY stock aside from some obd11 tweaks like my fogs/drls staying on for 30seconds after turning the car off and my soundaktor being disabled.

[Diggs24]

Reverse OBD11 tweaks ASAP.

 

[Blindeye_03]

Do I need to wait for the codes to reappear before going to the dealer?

 

[Diggs24]

Reverse all coding before doing anything else

 

[Blindeye_03]

Ok well my question still stands.... I get that.

When I Google these codes it's my wastegate or turbo. I'm pretty sure my soundaktor or headlights wouldn't cause the wastegate to be stuck open.

Nothing new has been coded aside from start/stop which I did re-enable 4 days ago now. And the code reappeared.

So again. Do I take my car in reversing every thing? Do they need to see the epc light or can they pull codes after I've cleared them?

 

[Diggs24]

Take it in with codes.

 

[Blindeye_03]

Take it in with codes.

So drive It for a week with the EPC light on and limp around? Is that safe? I have no other option unless I clear them.

 

[Diggs24]

If you've been resetting it and it comes back then keep resetting it but make sure it comes back before your trip in. Why do you have to wait a week? Are they that busy?

 

[norsairius]

Do the OBD11 tweaks really lead to concerns with warranty or something? I could see maybe if the tweaks impacted the engine somehow like maybe the engine response app or even the throttle response one, but the ones OP did seem fairly harmless.

I’m interested because I ordered an OBD11 but I also want to make sure that I don’t do anything that could void my warranty.

Otherwise, OP: as Diggs24 said, just make sure the warning light is on When you take the car in. No need to wait a week if it comes on sooner. Good luck, keep us posted!

 

[Blindeye_03]

Yeah I'm confused about that too. I turned my hazard light down too. Like these are silly mods. I'll revert them but yeah the first appointment I could make was for next Monday.

I've reset it twice now.

 

[Diggs24]

It's a MK7.5. They do weird shit when you mess with the coding.

 

[Blindeye_03]

Nevermind. It won't clear now. This will be fun driving for a week.

This is the worst possible timing that this could have ever happened. I'm hoping another vw dealer will get me in sooner but my schedule also sucks ass.

 

[norsairius]

It's a MK7.5. They do weird shit when you mess with the coding.

Well, dang. I was hoping to at least be able to use the key fob to lock the car while the engine is running and maybe a couple other tweaks, but I'm too paranoid about voiding the warranty with any of the electronics or the powertrain. Maybe I'll just stick to cosmetics for now. Too bad I already ordered an OBD11 from ShopDAP. I guess I can keep it just in case I need to read codes and whatnot (though I hopefully won't need it for that either, knock on wood). Maybe I'll ask my dealer and see what they say.

Sorry I took your thread a bit off topic, OP. Hope the issue is easily resolved! Let us know how it goes and if your dealer mentions anything about the OBD11 tweaks (or not). I wonder if they can tell anything's been done even if you reverted the changes?

 

[Blindeye_03]

Other dealers have even worse times for service so Ill be driving this car limping around for a week.. I need to sell the car anyways for budget reasons (divorce)..

 

[Blindeye_03]

Just a quick update.. No more light and I have boost. For now... I'm keeping my vw appointment though.

I'd they scan my car, can they see that I had the codes before I cleared them? I'm guessing no?
