So I get my 2008 CTT in the mail today -- okay -- by transport.

Goto get it inspected -- which you need to do to get it registered in Texas --
it fails due to a non-working horn.

So I jump on the forums and see how much a PITA it is to replace the OEM ones.

I don't mind going that route in the long run -- but I just need a working horn
for inspection -- or I get no tags.

Is there a point down stream in the harness that one could tap into
and install a quick and dirty horn.

thanks,

Mike

Ok I broke down and overnighted the darn horns -- will attack the bumper on Saturday.

Dang -- I was hoping not to have to wrench on a basically new vehicle - 18K miles

Literally just put my turbo back in my 951 Tuesday night.......

I'm tired of fixin-de-porsches.......

It's not super difficult if you're used to working on cars. After doing it once, it takes about a half hour start to finish. Remembering all the screws that hold the bumper on is the hardest part. Once the bumper is off, it's cake.

Thanks for the encouragement.

Your right, not difficult -- but quite the hunt finding all the right fasteners.
Just hate to mess with cosmetic stuff.

Took me maybe 2.5-3 hours taking my time. I'm sure I could do it in about 1.5-2 hours
the next time around.

Hopefully I won't have to -- as I put duct tape (with some perforations)
over the horn openings to keep the water out.

Muffled the sound a little -- but not much -- and certainly not enough to warrant having to
replace them again :-)

Passed inspection -- now to pay the state their taxes and get my tags.

Sorry to dig up an old thread, but I found this when my 2008 CTT horn also failed purchase inspection...I also read that the OEM horns have a high failure rate and taking off the bumper is not my Idea of fun. I upgraded them to these:





HELLA Supertone - $45 on Amazon

Fits almost perfect. I had to drill out the OEM mounting bracket a little with a 5/16" bit to get the Hellas to fit.

+1 on the Hella horns. I installed them on my 987 Cayman and Mazda 3 ( which only came with one cheesey horn ).

Did you have to install a different plug at the end of the wire for this aftermarket horn installation? Thanks!

Good idea on the Hella horns - not so good a place to mount them. They will still be susceptible to what killed the old ones - water immersion. A better location would be off the center divider support in front of the radiator.

I mounted mine behind the headlights so that if they failed again it would be a quick swap out and still plenty loud.

Just thought I'd post it here, I bought HELLA 011225841 Black 12V BX Trumpet Horn Kit (Audi) from amazon for $20 for a pair of low/high tone horns, since my left side horn was broken.

I thought I'd give it a try for $20, since I plan to upgrade the horn sometime in the future anyway. They're direct fit, looks to be pretty much the same as what was in the car and connectors are the same.



OEM horns are 420/510 Hz while these are 400/500 Hz. I replaced both sides as a precaution. Sounds decent, pretty much the same as OEM

2005 TT: Horn works when actuated via the alarm, however the horn does not work when the steering wheel pad is pressed. The 20A fuse for the horn at location 16 is intact..

Do you know if I still need to replace both horns?

deilenberger

Different horn. Replacing both horns is an expensive way to troubleshoot unless you go the Autozone route of inexpensive horns (which can't be much worse than the stock ones actually.) Mount them UP HIGH, not to the stock brackets.
