Since this is the first turbo charged engine I have driven, I am not too familar with the throttle response. I called the service advisor at my dealer and asked if there should be a delay between pushing on the accelerator and starting to move. He said there would be less than a half second for the response. I think there is a much longer time, it seems that unless I give it a lot of throttle, it is slow to respond. Should the trubo need to kick in before the car moves. When I get into my Subaru and touch the accelerator, it moves right now, instant response. I asked the dealer to check my computer and see if everything was okay and he told me that the computer is so sophisticated that it would tell me if something is wrong. I just think that when I want to move, I should be able to go without so much delay and without calling on the turbo to get going.

i'd say give it until your are done with the break in.. i drove an eos with 5k on the ODO and it felt different compared to my new one that hasn;t been broken in yet....

..then panic.

 

[eismeerblue]

Well, it has over 6K and it seems to be getting worse. The dealer did tell me that, at this altitude I should use 85 octane and I have for the last three tanks, but I am going to go back to 91 octane and see if that helps. I have never been happy with the response (until the turbo kicks in), even with the higher octane fuel.

I think the half second response that he meant was the DSG engaging...

I think what happenes is that your press on the gass.. the accelerates but slowly until it hits like 2000 RPM.. then two things happen.. you get max torque and the turbo might start kicking in.. so while the gas pedal may be depressed at the same pressure, your engine goes through a logrithmic-like change in power... so you get a lurch.. or as we perceive a delay in acceleration...

I noticed that after driving the eos for a while, when i get in my 300HP v8 car, I nearly snap my neck off because I got used to sanpping the eos pedal to get to that 2000 RPM line... I guess that was my unconscious reponse to the Eos odd lag..

but perhaps yorus is a different problem...

I had the 2.0T in Audi form before and I have to agree that there appears to be a slight turbo lag in the Eos version compared to before - it's small but noticeable - it definitely loosens as the miles go on though - I've had my Eos a month now and knocked up 3400 miles in that time - the engine is loosened up nicely now and accelerates much better. Otherwise I adopt the 'heavy right foot' approach that Arch mentions, which also seems to work quite well too!!. If you've got that sort of lag, I reckon you should get the dealer to check it out - altitude and turbo sounds like an obvious tuning issue!

I think I know the answer to this...

There is a component in the engine called a DV (Diverter Valve) that's responsible for recirculating the air/exhaust gases around the turbo system.

This valve is made by Bosch and they are notorious for failing as they are a plastic diaphragm type which often sticks/ceases. This causes the problems that you are experiencing.

You have two options: you can either ask the dealer to replace the DV with another but risk that this may too fail or you can buy an aftermarket one...

When I had the TT, almost all members of the club changed their DV for an aftermarket one such as Forge or Bailey which are metal and have a spring inside and are therefore much more efficient.

I have read on other forums that this is also a problem on the 2.0T FSi engine and those people that change to an aftermarket DV are much happier.

Please take a look at this link as it explains alot better than I can:

Thanks guys, I checked out the link for the diverter valve, but it doesn't say there is one available for the Eos or any 2.0t nor could I find a price. I will look futher into this issue, there is a distributer in AZ I can call.

My Eos is the first turbocharged car I have had, always subscribing to the "There's no substitute for cubic inches" school of thought.

They always used to suffer from 'Turbo lag' which could seem quite lengthy if you go by what motoring journos wrote, but modern ones are much quicker to respond and don't have the lag they used to have.

I must say I have been very pleased indeed with the engine in my Eos; it has no discernable lag at all and if you didn't know it was turbocharged you would never guess it.

So I reckon the villain of the piece must be that valve!

 

[Gavster]

Believe me, changing that valve will definitely improve throttle response, even if there is nothing wrong with the factory fitted one. I will definitely consider changing ours soon after the car arrives. Only problem is that it's much harder to change on the EOS than on the TT.

Gavster,

I have followed the link that you have kindly shared with the community but the EOS does not seem to be listed...

 

[Gavster]

Hi Tintin,

That's just a general link that I found for Diverter Valve info, there are a number available that will fit the 2.0T FSi - and a few that are the atmospheric blow off type that dump to atmosphere with a rather loud whooshing sound - not that any of us respectable EOS owners (or future owners) would want that on our cars

 

[Gavster]

Here you go, take a look at this link - this is what I was talking about. Makes for very intersting reading, even if you do not buy one.

If there is enough interest, perhaps we could arrange a group buy to get a discount although not very easy to fit.

I have an Eos 2.00 TD auto with DSG gearbox, sometimes, when slowing, down/decelerating, especially to about 30-40mph, or slower seems to throttle back, almost like a flat spot. The dealer says that their plug in computer shows no fault, and there are no instrument warning lights appearing. Could this be connected to the Diverter valve situation, or does anyone else have thoughts on this?

 

[tortoise]

throttle response is good if u engage the DSG in shifts, not in natural e D gear. a competent driver capable of driving well with the paddle shifts will enjoy the process, with minimal lag in gear changes and response.

that said, boring the throttle body and doing the 2.5" DP helps alot, and if u r into mid-high end pull, try Volker Iridium 8ZR spark plugs, bang for bucks!!

yea Steve , I know exactly what you are talking about , I have the same problem with my new EOS . I thought mabe it was because the engine was cold but it also happens after it is hot . It almost got me in a serious accident , i was entering a main road from a stop sign on a slight downgrade and i let go of the brake and throddled it slightly , no response , throddled it more , still no response , I ended up slamming the throddle to the floor to get the engine to respond and get me out of the way of oncoming traffic !!
It feels like it has something to do with the accelerator pedal sesor or throddle position sensor because the engine dosent stall , it just stays idiling while you depress the accelerator .
If anyone figures this one out please post your results , this could result in a serious accident !!

cheers

How did they fix this problem? My 2009 Eos did the same thing & almost caused a serious accident. They ahve had my car for 5 days now trying to figure out what is wrong. I have had to have my Eos towed 3 times in 2 months. I have less than 10,000 miles on it. Very disgusted at this point. I have never owned a VW before & I can tell you this will be the last time too.

 

[cappers]

I test drove the eos about 3 times (different dealers different vehicles each time) before i bought mine. I have had the vehicle about 6 weeks and found the lag to be very annoying but common to all of the vehicles i drove. I dont have the lag anymore because i did 3 things after much discussion with this forum, the dealer and APR
1) fitted an APR ECU 98 octane upgrade
2) fitted a carbonio air intake (they tell me this is the most important change for lag)
3) run it on 98 octane only
no lag (well maybe a little) awesome performance difference and goes how it should

 

[UnfadedSprkl]

I've recently been having the same type of issue. I have the 6 speed manual, 4.0 Turbo transmission and recently noticed during my daily Nascar Beltway driving that my Turbo is no longer kicking in the way it used to. It hesitates and then just the other day, it sputtered and smog shot out my tailpipes. I plan on taking it to have it checked out, but has anyone else had this issue? I am well over my 50,000 mile warranty and would really like to avoid the shell shock of a mega-repair. At least a warning from someone here that has already had this issue will make it easier to face!

Thanks!

I have followed and believed with you and my problem has been fixed. Thanks

Got my recalled dsg transmission letter

Replaced the metronic unit or something like that, and vw extended my warranty on transmission to 100k warranty. I went ahead and told them to replace trans filter to save on service next time.
