ysabelle Posted March 14, 2007 Report Share Posted March 14, 2007 I posted some time ago about a noticeable drop in performance between 4-6k revs. We all agreed that it was probably the fact that the wife had used normal unleaded instead of superplus. Anyways, since then, I have : - Run though a few tanks of V-Power - Had an oil change - Had a VAG 50/51 full diagnostic check (No faults found) Yet despite the above the problem seems to persist. In addition to this I have also noticed that : - The engine sounds a lot coarser on full throttle, it has only done 3.6k miles and some people say that it SHOULD get louder with nore time/miles on her. Is that right??? - Fuel economy is woeful, average is about 22-23mpg around town. - The engine on tickover is slightly 'tappety'??? I dont get any smoke when I give her the full beans or on cold startup so am scratching my head as to how I could diagnose what and IF there is actually a problem. Heres the question..... If I took it to a rolling road and it only put out 180 horses, could I take it to VW under warranty as proof of a problem? Also, what elese could VW possibly check other than stick a VAG com on her? Any advice/recommendations? Cheers! Link to comment Share on other sites More sharing options...
RedRobin Posted March 14, 2007 Report Share Posted March 14, 2007 - The engine, exhaust, and hence sound will mature but I think it will only be marginal on a stock exhaust system. Again, this engine does 'scream' a bit when working hard but it's still quite healthy. - Fuel mpg around town will be woeful, especially on short journeys. Not surprised by 22 mpg. - The 2.0T FSI does sound 'tappety' on tickover. A drop in performance would need looking into. You might consider phoning VW UK or your dealer and asking them to recommend a rolling road near you. You could even try your luck asking them to pay for it but I wouldn't hold your breath on that one! How much is your problem "perceived" or "real"? Try getting a drive in another stock GTI to compare back to back and take the dealer with you. Hope this helps Sunny blue skies out there....I'm out for a good blast in the car Link to comment Share on other sites More sharing options...
oxfordlad Posted March 14, 2007 Report Share Posted March 14, 2007 My stock exhaust have become more raspy over time, which I will add I like very much Tick over is noisy I agree, but I dont have any of the power issues you mention? Link to comment Share on other sites More sharing options...
JoeGTI Posted March 14, 2007 Report Share Posted March 14, 2007 Here in Ireland, its next to impossible to get anything other than 95 unleaded (unless you want diesel ) , so thats what I've used in my 2 week old GTI - no noticeable performance problems. Also, most of my journeys are short stop-start trips, my economy thus far is in around 27-28mpg. I'd be expecting over 30 on a longer trip.

wantmygti Posted March 14, 2007 Report Share Posted March 14, 2007 Robin's idea of driving another one sounds like a good idea. If the dealer is unwilling, go to a different dealer and drive one as if you wish to buy one. Link to comment Share on other sites More sharing options...

I didnt drive the car for a few months because I took delivery of my new A4 170bhp Tdi. This has a a large turbo which produces a very noticeable kick in the back when it comes on song. Maybe I forgot just how progressive the Golf is (in standard form) BUT I will rolling road it for my own piece of mind. The problems start when and if it comes back short of stock. I have a feeling that the stealers may just say that its one of those things.... sigh . I need a Focus ST to play with , she used to be all over them when I felt that she was running well. (See one of my previous posts). Thanks for the replies. Link to comment Share on other sites More sharing options...
AdyGTI Posted March 14, 2007 Report Share Posted March 14, 2007 Sounds like you've been spoilt with a Torquier diesel engine, so now the Golf just doesn't 'feel' as fast. On my GTI I've noticed that until it's properly warmed up, not just to the middle of the temp gauge, I don't get a surge of power around the 3.5k-5.5k range. I've intentionally haven't really pushed it before it's warmed up but the engine seems to be more powerfull without trying in that range when properly warm.

RedRobin Posted March 14, 2007 Report Share Posted March 14, 2007 ysabelle, to make a fair comparison you need to compare apples with apples and not apples with bananas. In other words, comparing your GTI's performance with that of an ST or A4 is simply not an accurate method of assessing if your GTI's performance/power is what it should be. If the standard GTI doesn't excite you enough, perhaps an appropriate remap will possibly deliver closer to your expectations of your GTI. A remapped GTI (with the right driver) should leave an A4 or Focus ST for dead, especially if you mod the suspension and brakes - Not that you need to race around everywhere.

petsy Posted March 14, 2007 Report Share Posted March 14, 2007 talking of upgrading brakes, I wonder if anyone would be interested in this group buy for StopTech Big Brake Kit for the GTi... Link to comment Share on other sites More sharing options...
Chungster Posted March 14, 2007 Report Share Posted March 14, 2007 Just want to say I've printed off the Stoptech template a while ago (as was researching BBK's) and they will not go behind the standard 18" Monza's without a spacer. As for the main point on this thread...mine gives poo mpg around town (but expected) but performance never drops when I wind the rev counter round to the red bit! In fact...the car is still lighting my fire every time i get in it and give it some. 9k miles on the car so far, 3 Track days and service due in 3 months time according to indicator.

RedRobin Posted March 14, 2007 Report Share Posted March 14, 2007 ....Looks very similar to the AP Racing big brake kit which is just 2mm bigger disc. Ferodo DS2500 pads? 4-pot? Coincidentally I've just come back from a very spirited drive through some sharp twisties, including 90 degree corners, and drove hard in order to overtake where I could. This was the first time I have driven so hard in the dry on this particular road with the AP brakes, and both myself and my passenger (a bike rider) were gobsmacked by just how effective and smooth those AP brakes are. They are truly awesome when needed. Response inspires total confidence in them without driving beyond any brake's capability. Sorry to be repeating this yet again but combined with the modded suspension and remap, the car enters a different league when asked to. If the StopTech brakes are as good as the AP Racing kit, then it's a no-brainer for anyone who has a remap. It's possibly down to whether the plan is to keep your car for a few years or not - Not such an investment if you plan to sell after only 2 or 3 years (unless you can easily afford it and it doesn't matter).

Chungster Posted March 14, 2007 Report Share Posted March 14, 2007 Oh the Stoptech's are said to be superior to the AP Racing kits in some quarters.... But it's the caliper design and bell sizing that means it sits further out than AP's do. So it won't go behind the standard Monza's but may do on aftermarket rims. They are slightly cheaper than AP's too but not by much. Link to comment Share on other sites More sharing options...
RedRobin Posted March 14, 2007 Report Share Posted March 14, 2007 Having driven several thousand miles on the road (not track), including 2,000 fast miles in Germany, it's difficult to imagine a brake kit better (rather than as good as) the AP's. For what it's worth, the new mag "Performance Tuner" rated AP's extremely highly in their tests. Methinks I should post some stuff in the AP brake kit thread. My AP's are a fast road kit rather than out and out track (which AP Racing offer of course). Horses for courses. Link to comment Share on other sites More sharing options...
RedRobin Posted March 14, 2007 Report Share Posted March 14, 2007 I've just read all the tech spec and fully informative info on the StopTech web site and their brakes sound extremely impressive indeed. I guess that if I didn't happen to have a 'special' relationship with AP, I would have seriously considered StopTech. AP Racing are fairly typical of a British company - They have been established over 50 years at the sharp end of motor sport including F1 and NASCAR and they absolutely know what they are doing but their marketing interface is not very sophisticated in terms of product presentation and information. They trade principally on their first rate reputation. Without driving a StopTech equipped GTI back to back with my AP's, my expectation is that there's very little difference.

JoeGTI Posted March 14, 2007 Report Share Posted March 14, 2007 Hi Fresco - Yes, but I'm almost certain that this "v-Power" here is only 95. Shell make the dubious claim that its cleaner/better for the environment. So it costs several cents more, for those who want to save the ozone layer I'm pretty sure the octane rating is the same.

fresco1 Posted March 14, 2007 Report Share Posted March 14, 2007 Hmmm ... ! There was a long debate some time ago on TSN about this, and I believe the outcome was that V-Power was in Ireland (and called V-Power) before it came here (Hampshire). As mentioned, I did a good few tanks on it in Dublin and there was no difference - I believe the octane rating was the same. But I didn't taste it, so can't be sure!

If the dealers will not play ball with a test drive in another GTI try a Audi TT, Audi A3 2.0T, or skoda octavia vRS im sure you could wangle a test drive in one of them to compare the 'pull' of the 200PS 2.0T unit to the GTI.

ysabelle Posted March 16, 2007 Author Report Share Posted March 16, 2007 The problem with test driving other cars is that no 2 cars are exactly the same. It depends on how they have been run in, how loose the engine, fuel used, number of passengers (at least 2 if I test drive) PLUS some cars are simply quicker than others. I think the only real way to test is to plot the curves on a rolling road and hope that the rollers are accurate. Link to comment Share on other sites More sharing options...

I've filled up with super about 80/20 to normal and honestly, I'm not sure there is a noticable performance gain. I reckon you've got either (a) no problem, other than a paranoid one, or (b) some sort of electrical problem and you need VW to run a diagnostics on it - perhaps something related to the fuel injection, or induction, perhaps?

[/ QUOTE ] VW ran a load of diags on it (50/51) which all came up 'no fault found'. Are dealers able to proactively detect issues on air flow or fuel injection before a CEL is thrown up?
