mis-shifting = CEL?

[rasosina]

Hey,

This may sound stupid to some (if not all) of you, but last night as i was driving to the mall, i tried to learn 'double clutching', and i mis shifted twice (i let go of the clutch before the shifter was in the right gear so it made that weird shifting noise). So anyway, on my way back, i realized that the check engine light is on.

I just wanted to know if that's what actually caused the CEL to go off... or could it be something else... and if it is from the mis-shifting, how serious do you think the problem is? is it something that you just reset and get on with your life, or could something be broken or worn out and be in need of replacement.

I've read about this vag com thing, and wanted to know if i could buy it from somewhere? if so, how much would it cost? cuz the auto shops charge like 80-120 bux just to diagnose the problem.


and any help/input is appreciated.

Thanks

why ar u double clutching, learn to drive

[Mike02A4]

Have autozone scan the code for free, report back and some of the knowledgeable guys will help diagnose.

I knew it was gonna be one of those threads after it began with "I was driving to the mall"

meh, nothing wrong with double-clutching, to each his/her own. but yeah you need to hit up the 'Zone.

[Molotov]

get in the zone

I seriously doubt a mis-shift would cause a CEL.

If all else fails, grind it till it fits!








(not really)

rofl... "hey man, i was driving to the mall last night and i decided to learn some double clutching" wtf is this the fast and furious forum now.... ? learn to drive!

[NiveK1970]

double clutching an A4 wow, get a dodge with a cummins :) LOL j/k

[vdubstreets]

yea really we have synco's for a reason.

[JustinCase]

What were you driving an 18 wheeler? Theres really no need to double clutch when you have synchros.

[n7plus1]

a mis-shift could def. cause a CEL....did you over-rev it? Do a compression test.

[A4Shizl]

I hope you did not over rev your car an void your warranty...

[n7plus1]

plus theres no way to clear it, its permanently burned into the ecu

Who uses a clutch to upshift?

What????

Icthink the problem fellas wasnt so much the double clutching, its the fact that this person was granny shifting that caused a CEL

And he forgot to live his life a quarter mile at a time...

[n7plus1]

What????

at least there isnt with acura/honda...i dont see why audi/vw would be any different. If the engine was over-revved and you try to say you dont know what happened, etc. they can pull up logs on the ecu and see that it was over-revved and theres no way to get to that part of memory...you can clear the CEL, but the over-rev will still be burned into unaccessible memory

out of curiosity, what code would the car throw because you grind the gears?
not being an ass, just can't think of why the CEL would come on.

he never stated he was grinding gears...i was under the impression he miss shifting like hauling ass from 3rd to 4th and accidentally put it in 2nd and over-revved the engine...its been done a lot

ok, i figured the rev-limiter would prevent this, unless he was chipped but judging from the post i doubt it.

And he said he was "making that weird shifting noise." Grinding? IDK

[n7plus1]

in these cases, rev-limiters dont do shit....your forcing the engine to run faster than its supposed to by down shifting to a low gear at a higher rate of speed.

[quat]

good point.

[n7plus1]

haha, thanks

[rasosina]

no i didn't over-rev the engine...

reason why i tried it was cuz a guy at work was talkin about it, so i thought i'd give it a try...

i was in 4th at like 2500rpm, and tried to goto third, but I didn't fully get the gear in 3rd so it made the grinding noise..

anyway, i guess i'll take it to a shop near by to see what the problem is. I just wanted to know how serious the problem is to know if it's ok to drive it around for a while before getting it checked out.

[rasosina]

it turns out the problem was 'system is running too lean'...

how bad is that?

the mechanic that i took it to said pay me 150 bux and i'll look at it today, otherwise i'll give u an appointment for next week


he told me that it could have a leak somewhere relating to the mass air flow.

so i'm thinking it's just some pipe that needs to be replaced... or could it be other things?

[FromS60toB61.8t]

maybe a new maf is in line for you

[quat]

Check the vacuum line for the intake manifold. It gets hard and cracks sometimes. I had the same problem, (system too lean) and this is what was wrong, replaced the hose and all was good.

how can i do this myself?

as i recall the mechanic was like we have to 'smoke' it to see where the leak is. is there a way for me to just do this myself without having to pay the guy $$?
