Doing the 80K mile service and have run into a problem. The oil is changed, all filters refreshed, motor mounts replaced, brake fluid flushed, but plugs need to be replaced. Never pulled mufflers with PSE, and am at a loss on how to remove the stainless braided vacuum hoses that are crimped onto the valves. The heat shield (driver's side) is off, but without removing the muffler can only get to two of the three plugs. Hoping for help and thanks in advance. FWIW ... 2012 GTS. The subject of another post on center locks.
Hi all, This will be my first post, thanks for a great forum ! I've recently purchased a exhaust system from Design911 in the UK which has the valvetronic function on. This is said to replicate the PSE which my car does not have factory installed. Wired it up and put the vacuum hoses, tested the system and it works fine. Over to the issue for my car: When starting up the car, the neutral positon of the valves is open, which means a lot of noice from the exhaust. When switching this by the solenoid, sending vacuum into the system and the valves closes. This means less sound. But when the valves is closed the car wont run properly at the RPM range of 5500-7000 RPM's there is also fault codes for misfire on cylinder 2. The strange thing is that this works perfectly when the valves is open. I've tried two differnet vacuum sources, into the ressonator and also for the left hand side cooling system vacuum solenoids. Without any differnce. I tried to run vacuum directly to the vacuum actuators on the exhaust without any difference and also tried manually applying vacuum and using a one way check valve to keep the vacuum while not connected to the cars vacuum line. No vacuum leaks, no fault codes when driving with the valves open. Same result every time. So have anyone had some similar issues to their car ? Thanks in advance for any help !
HI all, My first post here , beeing hiden reader for long time .. :) Im about to change my original PSE on 996 2003 Carrera to non PSE mufflers. Several reasons , first , original ones are done , open on the bottom edges , cost of new ones in Germany are "insane" and noise PSE is making .. So bought EISENMANN Sport Mufflers without valves , Now , questioon is not about how to remove mufflers , lots of articles around , good ones for sure but i could not find article explaining what you should do with original wiring and vacum lines if you instal normal mufflers withut vacum valve ... Im bit worried with electric part , do I need to change relay , reprogram DME , Also what to do with vacum lines. On the other hand, would like to keep original setup of wires and lines, for the future potentialy, kids are growing fast . So preffered option is minimal whats needed .. I Have parts manual for EU cars also WManual for cars till 2001 I think, but could not find any detail related to PSE vacum and wiring .. maybe searching wrong page .. :( Thank`s for support ..
