Does anyone know how many times this code will get thrown before the SES light comes on?
I ask because I just had Eric(Helix) install a 15% and a CAI, and when he started it up that code had been thrown twice. (Never had an SES before). He cleared the codes and then I drove the Dragon like a bat out of hell and also drove 712 miles home to WI and never got the SES again.
I'm due for my first inspection in <1000 miles, should I mention this to the dealer or was this just some weird fluke?

The dealer may say or do nothing because the code has been cleared, and they can't confirm it.
FWIW, it's the age of the computer controlled car. Get you own code scanner. It's a good investment.

P1229
But why? My car was running awesome! Although this morning the car did the usual cold start issue. But it has only done it twice in the last 10 months. Although only twice on the new motor.
This morning I went to crank the car and it just cranked and cranked. I then shut it off and then cranked and it turned right over.
So I drive to catch the train and noticed a SES light. Oh crap..
Well ever since my troubles with the last engine I have carried around a Actron 9215 Code reader. I popped off my OBD2 cover and checked the code, P1229. I then cleared the code so I could get rid of the light. Which for a VW means Injector Circuit Cylinder 5 Short To Ground according to obd-codes.com. I did a quick search on NAM and found @MSFIT had the same code recently, throttle potentiometer adaption fault.
Now that I know some what the cause I feel like an idiot for clearing the code. Now I have to wait for the problem to rear its ugly head 2 times more to be able to take it to the dealer. Also my exhaust sounds throttier…not totally a bad thing. But I wonder if my code came out wrong and my car is trying to tell me my CAT is totaly dead and my exhaust note is part of it.
