Title: Performance issues...resolved!
Post by: Boothy on March 14, 2010, 10:50:25 am
Downloaded Bluefin stage 1 onto my car yesterday and to be honest I'm not that impressed really. Seemed to have better pick up on the motorway but thats about it. My mate was in his standard Type-R with a total of 3 people in and I was in the mine with just 1 other person yet he was still pulling away from me from a standing start!
 This gets me round to the engine cover issues. I don't believe the air filter has been changed for at least 15k as I was going to buy a decent one at the last service and change it my self. I never got round to this so the filter will presumably be past its best. So I've bought a Pipercross panel filter to fit but after reading up on how to remove it I have only succeeded in snapping me my bloody cover!
 I read this (  http://www.swankmonkey.com/vw/jetta/2006/remove_engine_cover/  ) but I still failed miserably. Now I have a nice crack running from near the MAF to the middle of the cover. The link I read shows the rubber thingys in certain positions but the one in the bottom left (which came free when it snapped) doesn't appear to be where the diagram says it should be? Are all the covers the same or have they been revised on later models etc because it ain't coming free when I pull where it says and I don't wanna snap it again.

I'm pretty sure all TFSI covers are the same just with different dressing.

Stealthwolf did a reasonable guide to cover removal on here but the most important thing is that the engine is warm.
Sorry you broke your cover, they are very dear from a dealers but sometimes show up on ebay for sensible money.  :smiley:

a type r pulled away from you and it had 3people in? wouldn't this suggest more of a problem than just an air filter?

i might think my car is quicker than it really is but with 60 lb-ft more torque at standard and less people in your car id expect yours to at minimum keep up in standard form.

has your car been on a rr?

Go check your dump valve for a tear. Mine runs Bluefin stage one and would eat a type R withou too much problem.

Tackled the cover again when the engine was warm and it came away quite easy this time thankfully. I appreciate that it may be something bigger than the air filter thats causing the problem but the old one was black as coal! Put the new one in and it seems to be a bit better but I'm still not sure. For fifty pound I might just replace the DV with the latest VW one (revision D is it?).

Are there any tell tale signs that I  could look/listen for that might suggest the DV is cracked other than not keeping up with a Type-R?   And when I say not keep up I mean just ever so slighly pulling away from me but never the less, pulling away from me. The lad in the Type-R was also managing to keep pace with a 270bhp Megane with out too much hassle too! Surely this can't be right :confused:

were u at newmillerdam today??

sure i saw this car today or if not a very very similar one. I've got bluefin stage1 and have never had any problems with type r's

Aye lad that was me! I was parked near the ticket machine.
 
Looks like its a rolling run to check its pushing out about what it should.

Boothmeister, If it makes you feel any better (which it won't) I did exactly the same thing with my cover last weekend, cracked to bu$$ery and really pissed off, and I have removed it a few times in the past without too many problems, they key has to be a hot engine (mine was cold).

I have a stage one on both my wifes GTI which has done 83k miles and it made a big difference, and also on my ed30 which makes a Massive difference. If it hasn't made a really noticeable difference, especialy in mid range acceleration you have other issues, would def look at the DV.

Cheers

John

Rather than just get a new cover I am going down the ITG group buy route, might as well get more power if I have to but a new inlet system which I do now :-(

Cheers John. Gonna try get it on the RR at Well Lane Turbo Centre near where I live at least if I know its around what it should be I can relax (which currently I can't).

where abouts are you from mate??

how much will it cost you to get it rr'd and where abouts is that place?

I live in Ossett, not far Newmiller Dam. How about you? Are you local?

I can't remember how much it cost last time I went about 4 year but I think it was £50 for the RR and a tune up? Gonna give them a ring tomorrow to find out and hopefully get it booked it. If you 2moro you could try book it in for a similar time and we could have natter whilst its on there  :drinking:. Anyway mate here's the link:

Ideally if you have access to VCDS you could diagnose things easier.

No worries mate, I'll keep my eyes open for you when I'm out and about.

I assume you have an edition 30 ?
Given what youve described, I would be checking to see if you have uploaded the new map.
Sounds like you may have reloaded stock ..

Its just the normal GTi mate, not the ED30. I checked the bluefin device at the time and it defo said it had installed it.

Tried to get on a rolling road today but when I rang the local place they said they no longer had it so its not been possible. I have driven the car a bit more today on normal roads and was initially still unimpressed but then all off a sudden it seemed to have more UMPH and was pulling well right through the revs. It did that for a while and then stopped again, only really pulling up to around 4500rpm. It did the same again later on and I remember the same thing at one point when I first fitted the Bluefin. Its flat as a fart after about 4500rpm but when it changed you could definitely feel a huge difference.

Having zero technical knowledge does this sound like a likely side effect of a knackered DV? I've ordered a replacement anyway just in case and I've also spoke to Superchips who were very helpfull. They are going to have a look at the map and get back to me.

Sounds like a strong case of finding someone near to you to log your car with vcds to narrow down possibilities.
Title: Re: Engine cover woes....
Post by: NEWEY on March 15, 2010, 01:45:48 pm
i would look into this a bit deeper as i never had a problem with a type r even when it was in standard form my mate couldnt get away

Firstly thanks to MortyGTTDI who is meeting me tomorrow to have a look at my car with VCDS thing. Very much appreciated.
Secondly, I have bough a revision D recirculation valve as a precaution but I'm not sure how to fit it. I know I've seen something on here somewhere but I can't for the life in me find it? Has anyone fitted one that can talk me through it or can find the original post about it?

Cheers.

Its apparently on the turbo on the K03 standard GTi's

What you describing sounds like it could be your MAF thats dodgy.
Title: Re: Performance issues...
Post by: liver on March 22, 2010, 12:31:46 pm
here is a diagram showing where its located mate

(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fdaz.co%2Fmedia%2FLiver89%2Frandom_crap%2Fturbo.jpg&hash=2c78c6f1bd6fd7f196360ec44b0abc1e3b1cd38a)

you will have to jack car up, put on stands then get under to do it. I tried to get mine off when i had a spare 15mins but due to location i found it hard

its held on by 3 bolts, not sure if its a torx or what size mate

so 3 bolts and undo the plug for the wire and its off

hope this helps

I presume when Darren hooks the car up to the VCDS it will highlight any MAF faults etc so will wait and see what he says when I meet him tomorrow. Regardless of the outcome I'm going to fit the updated DV simply as a precaution and that they allegedly a much better unit. Thats for the assistance, especially the in depth walk through that Luke (Snapey) sent me. Wish me luck! :laugh:

Ive just sorted a boost leak on my car, it doesnt show up any faults via VCDS only when data logging will it show there is a problem. SteveP did some data logs for me when we were up at UD's and from the results it suggested it was the DV at fault. My DV was ripped and when on boost it whistled alot louder than normal. All fixed now and running very strong again. :happy2:

Did some mapping on VAG COM on my uncles A4 TDI. Was no errors thrown up for the MAF and it was still registering values. However the car was running like treacle. Wouldnt rev past 3k and had no grunt below that either. I spoke to the head tech at the SEAT garage i use and he says the MAF wont throw an error unless it fails compleatly which is unusual and that when they are faulty they do still register values - just the wrong ones. So we got a new MAF for it fitted it and it now "Pulls like a train again" according to him.

I got the new MAF for much cheapness from these lots shop on the bay of many bargains

Firstly, HUGE thanks to Darren (MortyGTTDI) for meeting me today and offering his assistance with VAGCOM to help diagnose any issues with the car. Muchas Gracias mate, very much appreciated indeed :notworthy:.

Anyway it didn't long to see that a couple of fault codes had been logged, one of which was the boost regulation valve aka, DV. I've already bought one of the revision 'D' units so gonna fit this on Thursday. Hopefully this will rectify my lack of performance and hopefully let me get rid of that pesky Type-R once and for all! :signLOL:

The second fault was related to my headlight washer system not working which has been like that since the ice age we had at the beginning of the year. Turned out it was a blown fuse which Darren kindly replaced for me whilst he was there. How goods that!!  :smiley:

Got around to changing the DV today which was causing the lack of 'umph' from the car. From the look of the old one I'm not surprised. Its shag*ed!

The car is powering away like a dream though now. I can't believe the difference the DV has made and I can finally draw the issue to a close and enjoy driving it again. :happy2:

I couldn't get hold of an axle stand in time to do it myself and I didn't want to be under the car on just the jack so I popped to the local garage I use. He only charged me £20 to fit it so I thought I might as well. He did say it was a pain to get out though.
