Throttle Lag

nightflight · Jan 20, 2010

Anyone know how to reduce the noticeable throttle lag on the 1.6crtdi? if i'm quick enough i can floor the throttle and get my foot off the pedal before the revs even start to rise.
At first i just put it down to turbo lag, but even when it's on boost there's maybe .3-.5 of a second delay between giving it juice and speed increasing

When it's on boost? You got a button I haven't?

Mine's the same. Definately no where near as responsive as my old petrol, but awesome once it gets going... I'm equally intrigued to know if there's any useful tips here.

same here on a 1.4 petrol sport too

Just learned to live with it...

yeah i have noticed this too.

for some of the other VAG cars which are also throttle-by-wire, there was a product called the "sprint booster" brought out to make the accelerator react faster. I am not sure if this item will work on this vehicle but may be worth looking into.

I read about that product as well. Only other option which I know some people wont be wiling to do is have a remap. I know they improve throttle response.

Apparently on the DSG models its better in Sport mode than it is in Drive.

I've discovered that if you rev beyond 1500rpm there's this thing called a turbo on the engine that gives you like a zillion more horsepower.

Apparently when this "turbo" is on it's called being "on boost"? i guess because it boosts you a bit?

Ahh, that's where I've been going wrong. I don't normally let it go over 800revs.

garethrobson · Feb 22, 2010

the turbo isnt really the problem though because i have a 1.4 petrol and i get the lag...

It is something to do with what the person said before about the cable on the accelerator pedal.

mardon · Feb 22, 2010

You even get lag on the supercharged models. Its much less lag than with a turbo though.

i have the same problem on a 16v spot arosa its a good half a second!... i am loking into the sprnt booster but i do not think its dooable on an arosa... the only other thing you can do it get another throttle body.. but there expencive and not a defnate cure.. apparently there was a bd batch of these made for the arosa but i do not know ow it stands on later cars.. i suppose as poted before you have t just live with it

Just wondering if anything ever came of this issue? Have SEAT managed to resolve the throttle lag for anyone?

I have a 2009 Ibiza 1.4 SE and the throttle lag is awful, really starting to annoy me now. I can put the foot to the floor and back before it even registers on the rev counter!!! That is not normal if you ask me.

Definitely an issue with mine too. I'm sure it's the same for everyone with a Mk5.

Whoever finds a solution for this would sure be a popular guy/gal around here...

Definitely an issue with mine too. I'm sure it's the same for everyone with a Mk5.

No trouble with my 1.2 TSI. It's a bit flat before the turbo gives full boost at around 1500 rpm but above that the response seems virtually instant.

CovMike · Mar 7, 2012

From what I have read it only appears to affect the 1.4 petrol (standard not TSI) and the 1.6 diesel engine.

It definately can't be turbo lag as my engine has no turbo.

It does appear to be a fairly common issue across the board with the above engines and I am surprised no one has had any success in either getting SEAT to resolve the issue or some of the more technically minded of us finding a fix themselves.

I have read somewhere that it is believed there is some sort of electronic interference going on somewhere between the throttle pedal and the engine that slows the process down. That is as much as I have been able to find out. Not even sure if that is true.

Any info would be greatly appreciated by all 1.4 and 1.6 drivers I am sure.

It's the same on the 1.2tdi, I was given one as a courtesy car back when my tdi fr was getting some warranty work done.

Caught me out a couple of times at junctions, luckily just roads with slow moving traffic but disconcerting none the less. I had to live with it for 2 weeks, but I wouldn't want to on a permanent basis.

I rang seat UK and they just kept fobbing me off saying there is nothing wrong with it.
I said and explained to them that it is dangerous.but they just didn't listen. Lost my patience, shouted at them and hung up lol

Nodoby has said it yet so I'll throw it out there. VAGCOM. Dunno if it helps, just nobody has brought it up on here yet...

Squirrel.

its the drive by wire.. i had my new potentiometer and it fixed it for a while but slowly its come back.. the only way u can have it fixed is ecu mapping (helps a bit) or a sprint booster.. by default the drive by wire system on alot of present seats are shiiiiiiiiiiiiii... rubbish lol

.. my arosa is still the same. its a known problem hence why seat has raised the tolerance to allow the signal longer to get from pedal to ecu.. sadly you have to live with it according to seat.. i now have a mk4 golf aum and the throttle responce on that is immence.. if youve just ran a mile n your hearts racing if you put your foot on the pedal the revs move with yor pulse lo!!
