iv recently noticed that there are five small leds on the underside of the dial surround on my classic. wen i start the car the leds light up 2green 2yellow and 1 bigger red. i was just wondering what this could be? is it some type of knock sensor?

it does soundlike it but shouldnt lite up unless knock isdetected,if all 5 are lit up then if it is a knock link summut aint right

they only light up wen starting the car and they light up in sucsession, once the car is running there not lit up!

Hmm, my knocklink lites up,when ragging it etc, but its not like a traffic lite, it could be green green flicker flicker amber amber amber flicker flicker etc for a while, if proper on it then a red now and a again on the limtier etc, thats how a knocklink should illuminate.

if they lite up green green amber amber red when you 1st start it like traffic lights/ a race starts etc then maybe it isnt a knock link as such, get a pic of it maybe ?


unless coincidentally you do get knock at start up ?

i would think there would probs be a bit of knock on start up. maybe its a start up sequence for it?? where do you think the actual knocklink box would be hidden?
ill try get a pic 2mro

If yo uhave LED`s in the dash area the box could be anywhere, theres 2 ways fo doing it, extending the box led`s which would mean a box is somehwere else not near the led`s or the other is just to remove the box lid and put the led`s through someholes meaning the knocklink led box would be behind the dash where the l`eds are.

if that makes sense, do they look like mine ? ( in between the 2 sets of dials)

this setup, i extended the knocklink led box, somy knocklink box is behnd my stereo.

ah i see, i would expect that the leds have been extended from the box then because mine are on the plastic cover above the dials.

i dont have 1 of these on my classic i have CEL light could it be, that its an import and it is the sti model so my clocks have a carbon sourround with a ittle sti logo on it

yep its a knocklink. At least you know someone has bothered to monitor det levels on your car webster. Its a good sign of a careful owner. Leave it fitted. if you ever see ambers or reds when driving, back off the throttle and investigate the cause of the det.

Thats if it is DET of course.

yea i tried starting the car today while watching the leds and only one green came up this time so i dunno y it lit all the lights up before
