"Check Engine Light" Not Lighting!

Im having such a weird problem. Recently, I noticed that my CEL light is not coming at all. I mean when the ignition is on without starting the engine I don't see the damn CEL light!


Any help is well appreciated. Its not the bulb because I had 6WB cluster retrofitted and I just tested with the original cluster, didn't work. I also checked the cluster fuses... :

It's designed to show CEL (and some other lights) when ignition is on, it should turn off as soon as you start. But to be safe check for codes with OBD-II scanner.

May want to check with MHD.
But usually the CEL will turn on momentarily before you start the car.

I can normally see all the lights come on when I hit the start button once, without pressing the breaks." Accessory Mode"

Except the "CEL" that never comes on and its quite worrying because I have all those mods and if something went wrong I would have no Idea..

I believe the CEL didn't come long before I had the MHD installed. But I will contact them, thanks for the tip.

Before that I had a JB Stage One, do you think that had anything to do with this?

Don't guess, just scan it for codes. MHB also has logging feature.
Better question, how do you like MHD? Also, how does it compare to JB?

JB Stage One doesn't alter the ECU. So, it doesn't have anything to do with this.

Okay. I will hook up my laptop and code the whole Dkombi again!

If that didn't work I will try hooking up ista+ and see what comes up.

It's simply amazing. I keep an old android phone inside the car and you really can't beat the feeling of remapping the whole engine with a few clicks on your phone.

The power delivery is super smooth and can't be compared to the JB unrefined turbo power surge! Also the features like "cold start noise reduction, max speed unlock and of course the infamous Burble settings comes quite handy"

VRSF but I wouldn't recommend it. Because I had fitment issues.

Spend a little more and get ER, AR Catless or even better the catted one. Here are your options!

I am still waiting for you opinion on HiFlo Catted downpipe. Have you test it in your car yet? I am worry about CEL which you say hit and miss. Am I sacrifice low and mid torque for gaining high end power?
Thanks.

Don't worry any significant warnings will come up on your dash monitor. But yeah that engine light is hilarious.
