Picked up my new black ED30 last week, and been running it in since then. After 1000k finally tried to open her up a bit, and have to say was totally underwhelmed. I am pretty sure the turbo is not working ! :angry:
4th, 5th & 6th feel slow, and no turbo surge, no turbo sound, nothing. Having had 2 petrol turbo cars before, I know what I was expecting.
So much for their pre-delivery inspection. :angry:
It's booked in on Monday at local stealers - fingers crossed.
Apart from that, the ED30 is great.
-
Bizarre :huh:
Keep us posted.
-
Not heard of that kind of fault before. I wonder if the DV has aprematurely blown :undecided:
-
There is vitualy no lag on the ED30 and the power is very progressive. I've had turbo cars and this one is very different.
Having said that it's pretty obvious if the turbo isn't working as the car will be brick slow with no pick up above 2000 rpm. I'm surprised you didnt notice this when running in.
-
Sounds like you're losing boost pressure somewhere in the system. I'd get it looked at before you do any damage.
-
On a similar issue, recently I have noticed that my standard GTI appears to have lost some power when accelerating, and could not hear the turbo whistle sound in the cabin.
I took it is for my first service and mentioned this, and they told me that they had upgraded the engine management software which seemed to slightly improve this - however I still cannot hear the turbo whistle which was very evident when I first had the car? Should I still be able to hear this sound clearly on higher revs - the car is just over a year old and has done 14K miles?

Still sounds like a blown DV
-
If this is a blown DV, will this mean that you would not hear the turbo whistle in the cabin?
-
A blown dv reduces power and leaks air from the system, which in turn would reduce power and the ability of the turbo to spool up as fast and so would then reduce the whistle sound too :nerd:
-
!!!! :sad: thats not good...
I'm at 350 miles still running in and its 'very' obvious this is a turbo car even on partial throttle
No noticeable whistle (unless you have the windows down)
But the 'push' is cert very obvious esp on the ED30 comp to the GTI
unless you came from a FQ300 :wink:
so somethings wrong Im afraid , and a major air leak seems an obvious choice either by a loose pipe or a dodgy valve that never closes.
keep us informed

I Sense one of these is in your future: http://www.forgemotorsport.co.uk/content.asp?inc=product&cat=0006&product=FMFSITVR
I highly recommend it, and its pretty simple to fit with easy instructions. You'll spend a bit of time on your back though, unless you get a garage to do it.
-
Will they work with a remapped ed 30 out of the box?
-
Yep
It's still controlled by the ECU so no setup is required. Turn the key and its working.

This post has me slightly worried. I get no turbo sound/whistle inside the cabin when the windows are closed - only a hiss sound when i let go of the accelerator. I do however get a slight whistle as i accelerate if my window is open. Car has done 8700 miles or so. Could my car be suffering as well? First time i've owned a turbo car so not 100% what i should be looking out for. The car has recently come back from a "tiptronic ecu" replacement as there was a fault whenever I put the car in full manual mode. They did a full diagnostic test after and there were no error logs.
Also, are there any warranty issues if i fit the forge dv?

You can't really hear the turbo on the GTI that much. If you really press it then you do get a noticeable whistle but under normal circs, no :sad:
-
Forge DV shouldn't affect your warranty as all it does is divert the air. It doesn't boost any pressure or up the power, or put the engine under any extra stress at all. In fact the Forge DV is a higher spec and if anything should help the cars reliability. :nerd:

I wouldn't worry mate. If the diverter valve is doing its job you shouldn't hear anything, except maybe a slight hiss when you back off the throttle. Even then you would have to have the radio off to even slightly hear it.
You'll know straight away if its losing pressure. Look out for the revs lagging when you apply the throttle and a drop in acceleration. If you really are worried then ask the stealer to take the valve off and check it. It takes 5 minutes.

Thanks for the replies so far. I thought the car seemed less agile than expected from the word go, but I didn't want to hold the accelerater flat to check. Anyways, I get no hiss on lift-off, no whistle on full gas, no nothing. The big giveaway is the crap power above 2500 in 4th, 5th, or 6th - so something is definitely wrong. I had a 2litre 16v astra a number of years ago, and it feels just like that in terms of power. i.e. non-turbo. Stealers said 'these things happen with modern cars'. WTF ?!?? After shelling out that kind of money I expect the car to have been checked - PDI anyone ??
Oh well, she goes in on Monday to get 'looked at' by stealers. I will report back after that. After all those months of waiting, the whole thing feels like a bit of a let-down now.
-
Pretty shocking but in my case the last few cars i've had must have consisted of the guys in the garage ragging the car for a few miles 1st before handover. All the new performance cars I have had were delivered about 8 miles on the clock and an average MPG in the low teens. How else can that be explained??
Maybe that's what blew your turbo???
-
I know its real shame to have it happen , but hopefully it will be and easy fix.
Have you tried getting someone to rev it with the bonnet up , to see if you can hear an obvious leak?
Have you had anything fitted recently that may have disturbed something e.g. an electrical connector or a hose?
obv you want a dealer to fix it , but id be too curious and have to look under the bonnet for the obvious stuff :smiley:
I' new to this car , but isnt there the air con trick that shows boost ?
re: mpg from new , I dont think that value is really much of an indicator , but yes it is down to chance!
Good luck and remember to report back
-
Stealers fixed turbo. :grin: Now she flies!!
Stealers said there was an error on the ECU, so they 'reset the ECU', and bingo, the turbo started working. Was told as it's not been used yet, it'll be a bit of time till it's running at full tilt. Does the turbo need 'run-in' like the engine ??
Anyways, massive difference, and experiencing what I'd payed for.
-
Excellent result, but no less than I would have expected.
I'm glad it wasn't the DV then. :smiley:
-
Bet It feels much better now.................... :shocked:
-
superb news :smiley:
Maybe someone with more GTI specific engine knowledge could let us know if this is true?
ECU fault = limp home mode , which I assume was leaving the wastegate etc open?
Turbo would still be spinning though as afaik the exhaust gases still go by it no matter what
, so I guess its already run in.
Id still go easy to bed it in for a few miles under boost conditions.
cant see how the turbo hasnt been spinning at all , any mkv gurus care to explain?
anyways , enjoy your new found torque mountain ........

Hmm, interesting. I've been following this thread and been thinking the exact same about my standard GTi but was a little hesitant to contact the dealer as I thought I'd be done for time wasting, especially as I've only covered 1,000 miles or so. :undecided:
To me, (like your description) the car feels more or less like a N/A 2.0 - there seems to be reasonable grunt up to about 3,500/4,000rpm, at which point, I'd expect it to fly but it doesn't - in fact at times it almost feels a bit asthmatic. I had a Golf Gt 170 (1.4 TSi) before this and it felt more raw at higher RPM for some reason, don't get me wrong the GTi is fast (as the speedo testifies!) but perhaps not so much as I'd have expected - there's also no discernible turbo sounds bar a VERY quiet tish from the turbo when lifting off (I'd have expected it to be slightly more pronounced/more of a spool up sound).
Perhaps I'll get the dealer to have a quick look to be sure.
PS. Sorry to make my first post a moan! :laugh:
