    I know its a bit chavvy but I couldn't resist ordering a Forge BOV spacer for the B7.

    The thing i need to know, it is something that can be fitted quickly from above ( I know its under the turbo somewhere) or is it a job to be done from underneath and dropping the undertray etc?

    Only asking because I might do it tonight if the rain holds off, otherwise I'll leave it till weekend.

    Alright!

    So bad timing! I had one on mine, and had it taken off on Monday so its sat waiting to go on e-bay, but we could have come to some deal.

    I had a go at doing mine but could not get access to all the bolts, i guess with the right tools you could do it, but i only had limited.

    Awesome-GTI did mine, took them about a hour to do.

    P.S - It sounds amazing.

    You have to do it from below, and remove the under tray, but then you can see and gain access.

    What did you take it off for Steve ? How does it sound as I don't want it to be chavy as I've already been there and done that when I was 20 in my Cav turbo. I won one on the Audi raffle which arrived today in the post so was unsure whether to fit it or not!

    cheers steve,

    I had a quick nosey at its location before when I was fitting my panel filter, job for tomorrow afternoon. Was gonna hang on till weekend but I'm an impatient little bleeder!

    And yeah, like speedy said, how come you took yours off? Did it make the car run badly or did it remind you of a 1989 escort rs turbo

    Mike - This is getting very spooky your car is the same colour as mine, same engine and remapped by the same guy and now you want to fit a fodge BOV !
    I have done this mate dead easy. You need to jack the car up and take the udertray off then its just 3 X 5mm allen keys to unbolt the stock DV I replaced mine with the version "d" which is much stronger while I had it off just to be on the safe side then slide the spacer in and nolt DV over it using the longer replacement bolts supplived with the spacer then refit undertray.
    Mine has been on for about 2 months car runs fine. Apart from my cold morning jerkyness but thats nothing to do with the DV.
    I dont care what some people think about it been chav its cool if you ask me and at the end of the day its my car !

    Chaviness aside, what real-world benefit is the aftermarket DV giving you?

    Sweet FA mate I am under no illusion I fitted it purely for the noise !

    However the fitting the revision D OEM Dv has imrpved driveablity as the old one was split and the car was struggling to hold boost I think so that was £30 well spent !

    :respekt:

    hey, don't get paranoid buddy, I've only been stalking you for a year, thats me in the bushes now outside your house ha ha ha...only messing, don't call the police!!!! :busted_cop:

    It seems like I've got a habit for it at the moment, I moved into a new house a couple of years ago and ended up buying a cheap BM 330ci sport which was similar to a neighbours, he then sold his car last summer and got a Black Range Rover sport, I'd been after for a 4 wheel drive for ages and ended up buying a dirt cheap blinged up new shape black Range Rover from an auction and that really got him worried.

    This guy ended up coming over one sunday afternoon jokingly asking if I was copying.... paranoya, its a bad condition, I've had people following me for years! ha ha

    Going back to the DV, I've got a feeling mine is on its way out, even though the car has only been remapped for a matter of days I'm sure the boost was stronger when I first had it done. I was going to fit the forge replacement TBH but if the audi one is only £30 I'll look into that for sure.

    Right I'm off outside get messy with my spanners, then I'll be off reliving my turbo charged youth impressing the young ladies outside pubs with my new found dump valve coolness:rockwoot:

    lol I had a feeling I was been watched but I thought it was some young ladie I had impressed with my dump valve !

    http://www.jkm.org.uk/performance/index.htm

    I have been using this place to buy bits who have been great both places know there stuff and will advise you on whats best I got the revision D dump from the was the same prices as going direct to audi cant remeber the exact price around £30 or 40 ish just be carefull though the spacer might not fit the revised dumpvalve as it is a slighlty different shape.

    Never have I been sooooooo let down, just spent an hour fitting that forge spacer blow off valve thingy and excitedly jumped into my car to listen to my new found street cred and..............pst, about as loud as a silent fart.

    I'm generally pretty clued up when wielding a spanner but disappointment doesn;t come close to how I felt, I took myself to KFC for a 3pm dinner because I hadn't eaten since 8am and to top it all off when I got home to tuck into my grub the tango tasted like rat's peess.

    Tell me I've done something wrong when fitting it and that yours sounds/sounded just like a proper bonafide dump valve from the good ole days? The car drives fine and boosts no problem but the noise is no louder than it was since I fitted the panel filter last night, just a barely audiable pst similar to the recirc on my old TT.

    Question - Could the DV be faulty or on its way out/not plugged in properly? I managed to break the wiring retainer clip on the DV whilst getting it off but it still pushed on tightly when re-fitting. I could push the piston of the DV in with ease, literally no resistance whatsoever. I'm going to have a look in another couple of hours when the car has cooled down again. Maybe I've trapped the seal when refitting, maybe the moon is made of cheese dunno....answers on a postcard

    Cheers for the link as well Marrow, that might come in handy

    I had the same problem mate you need the FMDV14T spacer if your going to fit the uprated OEM DV like the one pictured in that link. The one you have will fit your car fine if it has the stock DV so dont worry about that its only an issue if you want to uprated with the revsion D dv which in my case was worth doing as the stock one was split.
    I contacted fordge directabout it and a guy called chris told me to send it back to them and they would exchange it free of charge the service was spot on and they certainly know there stuff.

    Hmm mine is fairly loud to be honest ! Not all the time some times you can hardly hear but thats normally when you rev high then change gear and slam your foot down again guess the car is saving the boost ? Er dont know what to suggest but no its not as loud as an old skool DV but I guess thats because its controlled by the ECU ?

    Cheers mate,

    so..... just to get it right in my think head, the FMDV14T spacer that I have is whats needed when you fit the later rev D Diverter valve. I'll just order one of those DV's too if thats the case to get the desired sound/reliabilty.

    Only fretting a bit because I'm off to the west coast of scotland tomorrow visiting the outlaws for the weekend and knowing my luck the car will decide to play up in the middle of nowhere.

    As it is, I'll just go and check the connections onto the valve again later but I'm guessing if the spacer is designed for one valve and I've got the other, it isn't going to be make wooosh durst...(best impression :lmfao:) we all crave.

    This is what forge told me "The new solenoid 06H145710D is larger than previous solenoids and the FMDV14T is the spacer specifically designed for that valve. If you still have the spacer, can you check some dimensions with me ? The ‘upper’ portion of the spacer where Forge is written should be about 23mm tall, and the total valve height should be about 43mm."

    Hope this works better for you mate !

    Thanks again buddy,

    Spoke to a guy at that jkm in portsmouth and have ordered a revised and more reliable rev D DV and he double checked the spacer too so it sounds like it'll all be sorted in the none too distant future.

    Cheers for the quick repsonses today, I appreciate it.

    Mike

    p.s. whats the next mod on your car so I can copy you!!! ha ha ha

    No problem mate

    I am think about lowering it a little possible using H&R springs then eventually some 19`s but I have wedding to pay for so the chances of either happening this year are looking doubtfull !
    Got some NKG spark plugs sat waiting to be fitted to hopefully smooth the engine out a little will be intresting to see the state of the old ones.
