I had a CEL couple days ago and I was lucky enough to spot the problem in time and cured it.
However, the CEL is still on and I was wondering if I can reset the code.

I know I can un-plug the battery to reset everything back to default
But is it gonna to clear my radio code or my ECU mapping??

 

Vag com or a liquidTT.

 

If you fixed the problem, it automatically clears if the same code is not tripped within like 75 engine starts or some x amount of miles. Just give it a week and it'll go away.

 

^I used to clear mine with a hand-held like the ones from Advanced Auto Parts

 

The light is cleared today. Thx for the info guys

 

or just go to a Advanced Auto Parts store and they will read it and clear it for free....

 

Or, in the future, just disconnect your battery for about 5 minutes. Hold the brake pedal for about 5 seconds to make sure all power is out of the system, and your CEL will be gone.

 

^he didn't want to reset his radio

 

Ah. missed that. My bad. Although, kind of shady to not want to reset the radio...you'll have to enter the security code eventually...

 

Find a used liquidTT. Ive used mine about 20 or 30 times to clear codes. more than worth it.
