Mk5 General Area / Re: Potential fault - GFB DV+

Will do!  I hope this hasn't come across too dramatic and alarmist.  If it's happened to me, it's sure to happen to someone else...unless I am the unluckiest man in the world and got the one and only dud  :grin:

Besides the silicon pad thing, I didn't find it to be fit and forget.  Occasionally the piston would start binding, causing part throttle surging.  I had to strip it down, clean it and reoil it and then it was good again.  Had to do that every 6 months or so, or when I could feel the part throttle getting funny on me.

"Defo not fit and forget.  The vulcanized bond to the piston is a bit weak.  It may not affect everybody but as mine is a daily, problems surface sooner for me."

I appreciate we shouldn't be having to fettle this , rather it should be down to GFB but, if they're not willing to rectify the fault @Pudding has identified, then would a dab of appropriate glue (not sure if super glue/araldite or something else designed to mate the two together) be a fix for this rather than it going through the engine. Suppose it's that or back to the OEM DV.

I tried 3 different glues.  Super glue, Evostik contact adhesive and Gorilla 'fix anything' type glue.  None of them worked.  Super Glue just won't stick to Silicon - at all!
The contact adhesive worked, but I could peel it off again relatively easily.  That won't hold up to 25psi of boost blasting past it.  Ditto the Gorilla glue.

One thing I didn't try was silicon itself as a glue.  That might work, but to get an effective bond I would have to peel the pad off completely, rough up the piston surface and hope to realign the pad squarely again.

I love the design of the DV+.  It's clever and effective.  The piston just needs more work to last a bit longer.  I think GFB Australia will be quite interested in this.  Haven't heard back from them yet.

Hi Pudding

Thanks for the heads up. I had a GFB Diverter Valve+ fitted by AMD Tuning just over a year ago as the OEM part was shot. Therefore will get my garage in Leighton Buzzard to check it every service.

Can you keep us updated with any response? Maybe a bit of pressure on social media from a few of us might do the trick if it's stone walled.

Crikey, the last thing I need is that part failing and causing futher 'issues'. I've spent over £3k so far in 2 years of ownership getting my car up to scratch....  :slap:

Mk5 General Area / Re: Powerbank With Jumpstart UPBS 8000 A1 - Any Good?

Don’t have that specific one, but have a similar one for up to i think 6 litre, depending on quality they can be either good or bad had one blow up in the car put it like that.

Unless you put cars away for the winter there’s no real point as if you ever need it for your own it’ll probably go flat just sitting in your boot (electronics with batteries are best stored at 50% battery btw)

Thanks  :happy2:   These absolutely transform a GTI as a road car  :laugh:  Comfortable but still very capable.  Could probably do with a bit more spring for the track, but otherwise epic  :happy2:  I hope you love your ASTs too!

Yeah DSG..... I think I need to do it.  I'm getting bored of changing gears myself!

@Shoduchi - Man, seems that my KNC gearbox which should be the same age as yours has 25T parking brake. I was about the sent the diff back to Darkside Developments, but they said it is better to wait and look. My mechanic opened the gearbox today and said it has 25T. :jumping: :jumping: :jumping: 
I'm very happy about this because shipping to and back from Bucharest is expensive and takes at least 10 days.

Unfortunately all my brake pads for next year are 25mm thick:



Need to find out where to machine them to 18mm now.   :thinking:

Yeah probably!

I know I come across a bit man against the world sometimes.  I just don't like seeing consumers being ripped off with shoddy goods at premium prices.   £500 isn't throw away money for anyone.  You kind of expect a certain quality at that price.  Not even a brand new OEM airbox costs anywhere near that much, but it's 10x the quality!

Mine move as in wobble over bumps, but I can't see the auto levelling working during driving.   That is only noticeable when you switch them on and it runs the test cycle.

Wobbling over bumps appears to be normal for some xenons.  I saw a Jaguar in my rear view doing that recently.  I feel his pain as it's bloody irritating!!

Mk5 General Area / Re: injector cleaning
« Last post by Pudding on Today at 03:54:08 PM Started by mayesj86  »
A cleaner won't do anything unfortunately.  You can get them ultrasonically cleaned in a chemical bath, but personally I believe replacement is the proper fix.  The solenoids inside them can get a bit lazy on top of the usual pintle clogging issues, so best to start afresh.

It may not be the injectors.  Mine were replaced ~40K with new ones from the dealer, and it was walnut blasted in the summer and it's not the smoothest of starters either.

I don't think these engines like the cold very much when they have some miles on them.
