no power at first gear (sometimes)


Recommended Posts

Sometimes when in first gear (moving onto a roundabout etc, where a good start is essential) When i put my foot to the floor to get on the roundabout quick etc for example the revs will go to the top but there is no movement, a bit like wheel spinning except the wheels aren't, all revs and no actual power to the wheels? Is it clutch slippage or the belt?? All other gears are fine but I'm having to get straight into second to avoid being shunted as i don't trust first gear. As stated sometimes it's fine and then sometimes it does nothing.

any ideas

could be a linkage problem? dont sound like its engaging properly? or could be clutch or flywheel or release bearing hanging up, if it was the clutch you would notice it in other gears too usually,slipping etc, also check nothing has come adrift below your gear shift in the consul could be some worn component as first and second are the most used gears

the gears are engaging it just has no power? strange how it is only in first gear? It also loses power on full throttle in first (it will give full power then suddenly lose it (almost like reving it in neutral. I can liken it to stalling but the engine is still running. Strange problem.

do the revs shoot up mate? coz that prob clutch slip,easy way to tell,rev about 4k at a stand still,then drop the clutch in 3rd gear,if she stalls clutch is prob fine,if it revs down slow then stalls the clutch is slipping

could be the elec diff lock,if i dont pull off from a stand still hard the power can cut to stop eccessive wheel spin?

clutch down (engine running) , into third , hold revs at 4k , drop the clutch . and then see what happens - as above ^ .sounds like either very smooth wheel spin or clutch slip :)

Thats completely wrong. Well done.

All the "traction control" does is apply the brakes to the wheel that is spinning to get the diff to push power to the other side.

I still don't get it ... is this done without moving the car? basically rev engine at 4k put it into third gear and then take foot off the clutch. Sorry i don't understand what you mean by 'drop'

if u spend the time to read the post and not reply sarcasticly,u would know that vw offically called it EDL . i know its not a proper diff,i was trying to explain if he had a loss of power in 1st gear only,then that could be the t/c cutting in as u said to stop any chance of wheel spin

And if you bother to read my reply you will see that the traction control or EDL as you like to refer to it DOES NOT CAUSE POWER TO BE CUT. It simply applies a small braking force to the spinning wheel.

Also, just for your reference, it only comes in under 20mph and does sod all to aid traction.

Just explain to me, how is a diff not a proper diff??? A diff is a diff, is it not????

does nothing to aid traction? so whats it for then? display perpose? not once did i say it caused power to be cut,yes it applys the brake to stop wheel spin,i agree there,and i was implying it isnt a proper lsd or a subsitue for one,i didnt type that properly,i didnt mean it didnt have any diff at all,i meant not a locked diff so sorry for not writing it right

i dont want to get into a slagging match mate,i just was a bit peeved that u came bk sarcasticly,why not just say u dissagree?

If you know it doesn't cut power, then explain to us why you think it can be the cause of a loss of power in first gear, because I can't see how you come to that conclusion.

It does nothing to aid traction because it only works under 20mph and it doesn't cut the power, if it cut the power it would be worth having. Its one of the many reasons I opted for an LSD.

because loss of power can be mistaken for alot of things mate so i was mearly suggesting that that could be it if u didnt know the vr's had edl,i mean il be honest i didnt realise mine had it till i read up in the book,first time i pulled out a juction i wondered what it was lol

i know it doesnt really do much for traction but that is what it is for,thats why i stated it,yea it doesnt do a great job but its there to help traction it says so in the book,and as iv said i realise it doesnt do much but it could explain the loss of power only in 1st coz when it cuts in on mine(listen carefully for the abs clicking lol) then u could take it as a loss of power.although as u have quite rightly stated is doesnt effect power directly,it does slow ur wheels down by applying the brakes,hence the effect of loss of power.

anyway have u tried the clutch thing yet mate?

no mate because i still don#t understand it LOL so i sit at o mph with the engine running in neutral ...revit to 4k revs in neutral. put it into third then take foot off the clutch straight away? sorry but if i do thiws do i keep the brake on??? Surely if i put it into third the car will move???

Ok so what you are looking to achieve is a noticable difference in sound compared to speed. Remember as a youth - variable volume constant speed cars? Well same concept! You are physically looking to see if the rev counter increases and the speed remains almost the same (obviously it will climb/go faster and I am quoting worst case to ensure the point is made).

The best way to spot it (imo) is to drive up a hill and see if the effect is there. Place in a gear and accelerate and the sound should increase and not the speed. It is a noticable effect!

Do it in first as that is the gear you are familiar with and vary the amount of strain you place the engine under. I.e just tickle the throttle and steps down to see if it always pulls or only in cetain positions that it does not!

The guys are asking you to put it into a gear where it would normally stall. If the cluch is slipping then the slippage of the cluch will mean the car may not stall!

If you imagine you deliberatly make the cluch slip by movement of your left (clutch) leg when start off from standstill. We are trying to see if the cluch is excesively worn and that creates the same effect.

If the cluch is slipping you should notice it getting worse to the point of it sliping in all gears as soon as the engine is put under strain at any speed.

If that is not happening then we may all be scratching our heads a little as your notes are a typical early sign!

Sorry with the egg sucking and I hope it helps ;)
