Re: 16618 - Boost Pressure Regulation: Limit Exceeded (Overboost Condition) –
Sorry to hear of your troubles. I have a Transporter T5 doing exactly as you describe, power loss, no warning lights. It just feels like the turbo stops spinning.
However since then, the problem has quickly (i.e. within days) got worse and now it feels like the turbo is pulsing.
I am awaiting support from Eshrules as to how to get the drivers for the VAG-COM cable he provided seen as I'm running a new laptop, but I expect to see an Overboost code like yours.
Would you mind letting us know how you go on?
