Hurra! Neither Brake Booster failure nor CEL anymore, brakes precisely and the beast roars as it should be  . Took several weekends to deal with the  aftermath from winter driving (fun, but somehow regret...) .  Now washed & waxed, and happy wife for life...:drive1:Thanks once more to the folks here for the guidance.  

In turn - let me share my fix with  illustrations: 1. drill hole in old tube close to firewall to keep the substance but arrest the crack growth; 2. Pull rubber tubing (1mm wall thickness (some old Nissin brake hose seath from my motorcyle used-spares box (Typically collecting and I don't throw stuff like this away as there will be a re-use someday...)) over 1.5 in and the old spigot on the counter part ; 3. I also re-did the joint on the Tee below motor mount using a 8/12 mm ID/OD rubber tubing. To connect  this tube with the old plastic line I found some 1/2 in ID PEX tubing (Sharkbite...some residue form my last plumbing project on the house). This was a light interference fit by hand, and instantly perfectly sealed (some metal clamps maybe for safety , but I will leave it for the case the joint fails...).  That's it. After a few minutes drive around the block the BB failure msg was gone, and the CEL a further 15 miles down the road. Attaching few pix   


Nice looking repair job done right there. Description of Fix and pictures, top man.

      what causes fuel pump fuse to keep blowing FS 13 it is for right side fuel pump, I changed the fuse but its blowing again.
    • By R88STER
      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

      First time post... hope to start contributing to the forum now!
      09 GTS with 93k and excellent maintenance history, recently getting long cranking times and sometimes rough idle at startup.  Starter is working properly so we can rule that out - not sure what to tackle first, coils?  fuel pumps?  HPFP?
      Durametric codes:
      1023 Ignition Coil D Primary/Secondary circuit - upper limit value exceeded
      1026 Fuel high pressure implausible - value below lower limit value
      The 1023 keeps coming back when cleared but never throws a CEL, the 1026 has been very intermittent but will throw a CEL.
      I swapped coils 3 and 4 (assuming D is coil 4 and coil 4 is rear-passenger side of engine?) and still get the 1023 code for "D" but no misfire codes.
      I tried pulling fuses 13 and 14, independently, and truck starts on both fuel pumps (with long crank).
      Logged with Durametric the fuel setpoint vs. actual pressure and I get 40bar at idle and it seems to keep up OK while driving up to 120bar at WOT.
      Plugs were changed at 80k but I believe to be on original coils and fuel pumps.
      So before I start throwing parts at this, any advice on what to troubleshoot next?  Still fairly new to the Durametric so anythink I'm missing there with respect to data logging?

      Hi Everyone,
      So recently had a fuel pump go out on my C4. Conveniently way far from home. Got a local shop to repair, and they put the fuel pump in from the C2. The car runs, but doesn't feel quite right. Does anyone know the difference between the two pumps, apart from the part number of course? Wondering how far to push this.

      My left fuel (primary) pump went out on my 2004 Cayenne S, when I went to order the parts from www.sonnenporscheoemparts.com they said Porsche updated the fuel pumps and I would have to replace both because the old fittings will not fit to the new pumps. Is anyone aware of this update, have they installed a old fuel pump with a new one... or is it just best off to replace both at the same time anyway as if one goes out the other will be going soon also? Also I pulled fuse number 14 so I can drive with just the right fuel pump, does anyone know how long I can drive like this, parts wont come in for a few days. Thanks!
