Hi, my dealership wants to charge me $1900 to replace a leaking symposer. Is this needed, or necessary? It’s a 2015 F-Type, and I don’t care at all about the vroom-vroom aspect of this part. Please advise! Thx!
Not needed at all, plenty here including me have permanently disabled it, some have even removed it completely although that is a pig of a job.
Disabling it takes 5 minutes, just shove a suitable bung in the pipe, there is an instructional post with pics somewhere on the F-Type sub-forum.
Most who have disabled or removed it did so because we found the sound intrusive, unnecessary and just wrong.
Thank you! They are telling I really need to have it done
They are trying it on hoping you will pay for completely unnecessary work.
The symposer does nothing except pipe intake noise into the cabin, see the attached image, and disabling or removing it does not and cannot effect anything else.
Hello,
You have found your way to a collection of true Jaguar Experts, who know what's Really needed to keep your car in tip top condition and what's not, and who have no Profit Motive or other agenda, only a love for the cars.
Welcome aboard. Since your mechanic reports that the symposer is "leaking", then there is likely some repair actually needed. The symposer is basically a vacuum actuated part and "leaking" could mean that the engine is sucking unmetered air through a crack in the device which would negatively affect fuel economy, emissions, driveability, reliability and longevity. I second the motion to take to an indy for a second opinion. It could even be just one of the hoses or a loose connection.
But if the symposer is defective, I like the suggestion of just disabling it. However, in the link provided, the 5-minute job won't stop the "leak" as its still getting vacuum from the manifold. You'd basically need to disconnect the device and plug where it connected to the manifold, hose #11 in the drawings. Further down in the thread is a post showing how one user removed his symposer altogether. Since yours is supposedly defective, that's probably way to go in your case. A Jaguar dealer probably wouldn't do that, but an indy might, particularly a performance/race shop that sympathizes with the anti-symposer crowd and has some fabrication capability to make plug (rather than just stuffing a wad of foam rubber in the hole.)
However, most current F-type owners aren't thinking about future values when the F-type is as old as the E-type and they're not competing on a racetrack anymore but instead being inspected by concours judges on a lawn. If you decide to have someone remove the symposer, don't throw it away even tho its broken. Believe me, when its no longer a $300 dealer part but a $1,000, once in a decade holy grail find on ebay and the difference between a 1st or 2nd place finish at Amelia Island, somebody will be glad to have it and will figure out how to fix the leak. So don't cut anything or otherwise do any more damage to the symposer or its related parts. Just box them up, label the box clearly what it is, store it someplace safe and remember to put it in the trunk of the car when you sell it on or trade it in.
If you haven't done so already you should add your car details to your signature to help others to help you.
