Warning Lights come on!

Recommended Posts

Okay, I fitted a induction kit, a while ago, no problem, Ive now fitted a HKS SQV BOV in place of the stock item a couple of days ago, and the car feels faster/quicker, this could have been because the old stock bov pipes where leaking, anyway, i have had the red Triangle and red circle warning lights come on a couple of times, under hard acceleration or quick squirts of power, the car dosent cut out or stall, but after 3 secs or so the lights go out! (its an 93 auto mkiv TT by the way)

 

any idea's what will be causing this, the only thing i noticed was that the small pipe ontop of the bov came off, i replaced it last night and again the lights came on, this time the pipe was still on, i have replaced the pipe again today with one more like the thing i took off incase the new one was more restritive, than the old.

 

Anyway is this likly to be related to the HKS BOV, or has the increse in boost (from no more leaks) caused the ecu to cut power (or something like that), any advise or ideas .......... failing that i think ill stick it back to stock!!!! rather have a happy car that a moaning one!!! or is it completely unrelated and i should look else where1

 

Cheers

Do an ecu error code read, short a piece of wire between terminals TE1 and E1 in the diagnostic port under dash or in engine bay with ignition turned on then read the engine check light and post the code.

exactly the same happend to me when i did my HKS BOV, its still like it now but i am 99.9% shure it is slightly low brake fluid, dont rule it out as mine looks like the level is good but it still flickers on with the little red brake light in the right hand round fuel/temp gauge. (i know i should top it up but i have nice new racing fluid to put in when get time :D )

lovatt,

 

Doh!

 

Im such a F$%^ing idiot, ive just taken the car out for a run to see if the new pipe worked on my BOV, and no! lights still came on, this time i noticed it alot more, and YES its the brake light warning light, i never had a chance to see it before cause i was looking ahead!, doh DOh and fugging Doh!, fuliud was on MIN, toped up fluid and Ta Da, no more lights!!!!!!, I feel a right plank, oh well at least its not my HKS BOV! Phew,

 

I didnt think it would be the brake light as i just had the UK brake conversion done with 5.1 Fluid so thought it was full, Obviously NOT..........

 

I think i should be the only member today to honestly say.... :stupid:
