I just got this code as well. Did you ever figure out why?

I think it’s Lozic tune and EWG control don’t like eachother that is my guess.

it went away after restarting the car and have never seen it since.

What Map do you usually run in? I up my boost using EWG and got the code. Turned off EWG and so far so good.

Map 0 90% of the time

Any chance you remember if you weren’t on map0 for that time?

I just got it confirmed it is because of EWG.

I got this code last night...ugh. I was in map 6 should I just remove the EWG wires or try running it in map 0 and hope the ECU has learned to play nice?

I've noticed the exhaust definitely made a different sound whan accelerating when the light came on.

I run map6 but you have to make sure bit5 is turned on. That way it will disable EWG.

Let me know if that works.

I have the same code p259e does anyone know how to fix or what I should be looking at, I have been told to at the waste gate rod and tighten it up more, not sure if this is correct?

What mods do you have?

 

[Theo.skev]

I have a catback exhaust, air intakes and have removed the jb4

No other tune etc? And you have got code since removing JB4?

 

[Theo.skev]

No I had when having the jb4 on cleared the code but I have not boost, nothing I do seems to work

Sorry- let me make sure I follow. You got the code when the JB4 was on. You then cleared the code and removed it but the code/no boost is still happening?

 

[Theo.skev]

Yes I lost the boost with the jb4 on so I removed it thinking it was because jb4 but has not made any difference

Do you still have a check engine light? And how much boost do you get now?
