Shift light???



Does this also act as a warning light for any reason? I ask because mine keeps flickering on under medium/harder acceleration. Don't know whether it's just typical Renault wiring/electricals though. Any help much appreciated.

Please type 'shift light' into the search, it's not a shift light at all. Your thrashing your car as it's an over rev light.

I think the lad means during acceleration but well before he gets to the limiter. Surely noone is that stupid to ask if it was happening whilst bouncing off the limmiter!

It is cliosport after all...

I'd at a guess say it's a dodgy electrical bit somewhere. You don't buy a sportscar to sit and w**k over, you drive it.
 
It lights up green when you're approaching the limiter to warn you you're over revving the engine.

If it's flickering or flashing, when you're not near the limiter you may have a problem somewhere?
 
Thanks for the bashing about over revving people but it is flickering at as little as 2k revs, no wheelspin, no moronic driving, just accelerating normally.

As for the 'shift light' comment who really cares what you call it, you all understood what I was refering to.

Thanks Sam Clio16v, AstoN and xzibit for the helpful/constructive comments. I think it's dodgy wiring too just wanted somebody else to back that up for me and that it wasn't a known problem.
 
I would also like to point out that 'over rev light' is also wrong cat 171. If you get your Renault spec sheet or price guide out it is actually an 'Optimum Gear Change Indicator'. I think Shift Light is closer to the mark. ;-)

Any useful suggestions as to what could be causing the problem anyone?

Yeah the 182 handbook says it's an over revving warning light and that you should change gear. I think they changed the description somewhen.

Yeah i dont take my car to the 'light' however it has a good few hundred revs aftert he light before it hits the limiter, therefore this would indicate it to be a shift light. Otherwise if it was an over rev i would think it would be set at the limiter, the limiter is set at the limit for a reason - its the safe limit.

I may be wrong but thats my $2:eek:

Briefly - if you have the car re-mapped and the rev limit raised, does this raise the light with it, if not and thats the over rev then there would be no point raising the limiter??

I think you lose the cold 6500 limiter and the shift light doesnt change

I think peak power is made at about 6600? ussualy rev to 7000 myself

Im sure the fastchip map moves the limit out to 7800rm?? i think mine would rattle itself to bits at that lol
 
My info is coming from the 1st Jan 2004 Price Guide and it is listed under the 172 Cup and 182 as an 'Optimum Gear Change Indicator' but I really couldn't care what it's called it doesn't really change what it does.

The problem in all truth hasn't happened since starting this thread, so I'm just gonna push the little niggly thing to the back of my mind, pretend it never happened and ignore it if it does come back. Lol.
 
I have no idea what the light is connected to, other than it must have a connection to the ecu. Nothing stupid like flashing if gearbox oil is low or something like that?

Or maybe just a dodgy connection?
 
What colour is the light when it flashes orange or green?

When your overrevving it is green (no problem) if its green i suspect a electronid fault

If its orange it may well be a gearbox fault

Check and let us know

I'd ring Renault and ask but being an ex employee I know that my dog would know more about what it could be and he would be better at making up an excuse to do 20hrs worth of diagnostic work.

Not sure about the 182's but the mk1 172's are down as having a 'Optimum Gear Change Indicator' which to me sounds more like Renault saying its a shift light than a over reving light.

In anycase as already said, depending on what you use your car for, usually when mapped the cars rev limit is raised well above factory set figures so the light works on what you want it to be ......

Lol @ Renault describing it as an optimum gear change indicator. :D

What do you mean please elaborate?

Optimum gear change should indicate the best time to change gear for better fuel efficiency. BMW use it in their Efficient Dynamics, you pull through the revs, when it reaches suitable mpg for the next gear at say 2,500 revs it brings up a light to indicate a shift up/down is required to get better fuel efficiency. Some how i cant see shifting my 182 at 7,000rpm in every gear will be very efficient. Completely wrong use of wording. Gear change warning light would be more apt.

Unless the ph1 172 does indeed indicate the best time to change gears like the bmw efficient dynamics of course, unless its describing the same function of the 182 in which case it certainly isnt an optimum gear change inducicator by any means.
 
  Clio 182 & Saxo VTR
Well its obviously not going to be for fuel economy its for performance

Well obviously its not for fuel economy no, hence the point of my post in them calling it "optimum gear change" when blatently its not. Its not much in way of performance either, cant see hitting the rev limiter in every gear helping performance much.
 
if you shift when the light comes on then you wont hit the limiter ;) think thats the point they are trying to get across...

It depends what you class as optimum its quite vague but in the this case i believe they are relating to performance.

Even so taking it to the edge of the rev range doesnt always conclude to maximum performance does it? The point im getting across is however they have worded it, its blatently wrong.

Also in my 182 when the gear change light comes on im usually well into bouncing off the limiter so i dont know where you get that the light comes on before from.
 
Yeah its a waste of time i know and its in the stupidest place - i was thinking of wiring mine upto some bright red leds to get your attention more - would be useful on track i reckon!

Mine comes on approx 300rpm before the limiter - thats on a 172 may be different on a 182
