Make your S3/S4 bonnet release work better
Posted: Thu Jul 02, 2020 2:33 am
For those of you blessed with a single-handle, dual latch bonnet release I implemented two improvements that transformed its operation. This started with a brand new bonnet release cable assembly from SJ Sportscars, needed because the one in the car, which had never worked on both latches, finally disintegrated when I pulled hard on the handle and it came off in my hand. The PO had tried to graft a new cable to the handle with epoxy.
On initial installation the new cable had two problems:
The fix involved three steps:
With that done releasing the bonnet requires only a light and buttery-smooth pull on the release handle.
On initial installation the new cable had two problems:
- Even with the adjuster fully extended the cable was too long, causing the latch plates to descend forward of the latches
Even with ample lubrication under load the inner cable bound horribly against the outer cable with even the slightest bend in the cable.
The fix involved three steps:
- Cut the cable stop off the passenger-side end of the cable.
Slide onto the inner cable a length equal to the inner cable of Jagwire Slip Lube Liner (https://www.amazon.com/s?k=Jagwire&ref=bl_dp_s_web_0
Crimp or solder onto the cable end about 1/2" further down a new 1/16" cable stop. I did this with this tool: https://www.amazon.com/IWISS-Crimping-Aluminum-Sleeves-Ferrules/dp/B0195XJI6Y/ref=sr_1_2?dchild=1&keywords=iwiss+cable+stop+tool&qid=1593656903&sr=8-2
With that done releasing the bonnet requires only a light and buttery-smooth pull on the release handle.
