Sports exhaust button permanently on

[Sparkatan]

The PSE button light is permanently illuminated. Is this simply a faulty switch or something else?

I would try removing the switch and either grounding it or disconnecting power to it. To diagnose whether switch is faulty. If light isn't going off my guess is faulty switch

Exact model and year of your car would be helpful...

Sorry I didn’t reply sooner. 996 C4S 2004

I’ve since started to replace both silencers and found the PSE mechanisms didn’t move, probably due to their age, they look like original silencers and both had corroded at the seams and the N/S one had a broken flexible joint.

What I thought would be a Saturday job turned into a full weekend and I still only managed to replace one! The main problems were getting the old silencer off due to all of the bolts being very badly corroded. The three nuts on the mounting bracket were impossible to get to with the car on the ground even with the bumper off. I could just about get to the rear one but it wouldn’t budge and ended up rounded off. I ended up cutting the heads off the bolts on the two mounting devices and removing it that way. The downside is I had to fit the new bolts from the bottom with the nuts at the top which isn’t ideal if a nut decides to come off. 

 

I bought a silencer kit from Design 911 with the PSE option and here’s a tip. Although they say you can no longer use the dashboard button with their kit as it comes with a wireless fob, that’s not strictly correct. All you do is refit the two existing vacuum hoses to the new silencers and it works. You don’t need the controller and wiring that they provide. If you decide to use these and the fob then indeed you won’t be able to use the dashboard button. I now have a surplus to requirement wireless fob kit.

The silencers are smaller than the original ones and I had a bit of trouble getting the end pipe to fit. The alignment was slightly different and the connecting bracket was a poor fit. Managed it in the end but it took me hours to do it.

 

I expect the O/S silencer will be a bit easier now i’ve an experienced the first one and hopefully there will be less corrosion.

 

I’ll post again when i’ve finished and let you know the results.
