2003 Cab bumping noise when encountering bumps with top up

Recommended Posts

Hi all. I have a problem with my 2003 996 Cab. When top is up and I experience a change in slope such as turning into an uphill driveway I hear a bumping sound from the top of the windshield. Any ideas what this might be and how I might fix it?. Thanks in advance

Check the plastic covers on the tabs that go into the windshield header. If the plastic covers are broken/gone it leaves too much clearance and they can bump/rattle depending on how loose things are.

      I jumped the curb and the roll bars deployed.
      1. Reloaded the roll bars per owners manual
      2. Connected the code reader, roll bar selection did not load, said this option not their.
      ? is there a fuse in the roll bar control module

      This just started - When you turn the key to start the vehicle, there is a noise (hum) from the sub-woofer that's stays on until the starter cranks.  When the car starts, everything related to the radio is normal, but the LED on the Rear Defroster switch stays on all of the time.  I was told the Rear Defroster relay is bad so I purchase a replacement.  I'm having a problem locating this relay.  Is it located under the dash or behind the rear seat?  Which relay is it?

      Hello Porsche experts, I recently purchased a used 911 Carerra, 2003 and had the fuel pump fail.  So I looked around in Orange County to find a Porsche mechanic and ended up taking it to Hergesheimer.  They replaced the fuel pump but a few days latter I experienced something very troubling.  The car would start but idle was somewhat rough.  Revving the engine was a challenge in the lower RPM 1000-3000 then it became a bit smoother when driving with load on the engine in the 3000-4000 RPM range.  Alarmed by this I called the shop to bring the car in, but this was the day before the Rennsport Reunion in Laguna Seca so I dropped by another mechanic who brought up these error codes on a generic diagnostics tool:   P0134 Sensor Circuit No Activity Detected (Bank I Sensor 1) P0101 Mass Airflow Sensor / Circuit range issue Performance problem P0154 O2 Sensor no activity detected (Bank 2 post CAT ) P2098 Post Catalyst Fuel Trim System Too Lean Bank 2 P2096 O2 Sensor no activity detected Post Catalyst Fuel Trim System Too Lean (Bank 1) P0156 O2 sensor circuit malfunction (Bank 2 Sensor 2 post CAT)     Initially I thought this was related to the fuel pump replacement. So I called the shop who did the work and they said bring it over.  Their analysis identified similar codes and they suggested a few hours to review the harness and sensors in order to asses the problem.  A week later i am still trying to resolve this and wondered if I should replace the O2 sensors myself.   I have done brakes and other minor maintenance.  What is the opinion of the forum here on next steps?  I can provide further detail
