I have the GDE tune and just put in the weeks mod. My code reader says "turbo underboost" but the manual says "throttle position sensor" I have very little power after 30MPH. But it does accelerate, albiet, slowly. I put in new Samco hoses and checked everything, no leaks. So is it a problem in the TPS sensor circuit or is the tubo not boosting. I checked the vacuum and have 28 at the modulator.??? |

TPS sensor failure invokes 'limp-mode' - likely you bumped some wiring in the weeks elbow area - several sensors are on each +5v source - thus, a pinched wire can disable several sensors - recheck wiring in that area |

Tks But I pulled all the plugs on that side when I did the head gasket job and the weeks mob. Is there a chance that there is something I did not reconnect on the intake side after the weeks mod? |

Don't remember the code I had, but once I forgot to tie the clamp for the turbo hose. Could that be in your case? |

P0229 is a TPS malfunction. P0299 is turbo underboost. There is a conflict between your subject header and what you say your code reader is telling you the diagnosis is. |

Yep - KJ APS is up around 2120-2125, called Accelerator Position Sensor, since we don' need no steenkin' throttles............ - think his reader is using the TPS gasser version |

I was in error, it was 299/turbo under boost. I was putting up Xmas decorations and geiswig put in the seed of doubt. So I drove 40 minutes RT to check the code reader and as another suggested, the hose clamps. I did not have the clamp on the weeks manifold square/ offset so it is probable that there is my boost leak. I thought it more politically correct to get back to the Xmas decorations. Without these forums for my two older tdi s and my two crd s I would be in trouble. I would just buy a new car and join the crowd. |
