Sudden LP pump switch off

[Traf]

Hi everyone ! Long time no see.

I'm getting a very weird issue since i upgraded to B58 coils, while driving all of a sudden, LP shuts off and engine dies. The issue never happens when i'm flooring it, always at low to mid RPM on very light loads.
After letting the car sleep for 5-10min, she starts back like nothing happened. I know what people are going to say, EKP overheating but i am convinced the LP dying is the consequence of a more subtle problem.

Has anyeone faced such an issue before ?

Thanks !

Interesting. Why not the EKP?

Interesting. Why not the EKP?

Multiple reasons:
-It does not happen when the demand on the EKP is the highest
-It happens sometimes when the car is barely warm, so no harsh driving, EKP should not be hot
-It started happening after the B58 coils

Now, i'm a not running the inline resistance like the one you find in the stock B58 coil boot, could it be causing electrical noise ? Idk

I have another EKP so i will try swapping it, just to be 100% sure, but it's risky because the car leaves me stranded and it can be dangerous.

DIY B58 coil conversion?

DIY B58 coil conversion?

Kind of yeah, but with proper lenght boots, so it's not tracking or anything. Wiring is good quality, no apparent shorts.

Well well, after changing my EKP, issue seems to be gone... What really threw me off is that it started happening at EXACTLY the same as i started messing with the coils...
I took the occasion to add active cooling to my EKP, self contained, lets see what it does in the long run.

Same thing happened to me. EKP swap solved it. Sometimes they just die...
