Product Description

​​​​​​This valve is a replacement for the OEM valves under the part numbers; 06A145710N, 06A145710P, 0-280-142-114 , 4441895 (Saab) .

  • Quicker throttle response
  • Reduced turbo lag
  • World leading springs for more precise operation and consistency
  • All internal and external components have been made in the UK
  • Replaces the weaker plastic valve 
  • Pistons use heat stabilised Viton O-rings
  • Lubricated with high temperature Mobil1 grease
  • Fully serviceable and rebuildable in minutes
  • Unlike other valves on the market, ours produce no check engine lights (EML)
  • Covered by the unique Forge Lifetime Warranty*

The standard factory fitted Bosch valve was and still is prone to failure of the rubber diaphragm inside, leading to a boost leak.

20 years ago, Forge Motorsport recognised this common failing and developed an aluminum two piece replacement recirculation valve, utilising an aluminum piston as a replacement for Bosch plastic valve, (originally the FMCL007P). This valve soon became the most copied and imitated in the valve marketplace.

The FMDV008 turbo recirculation valve is the result of 25 years of continued experience and engineering expertise. With the reputation for innovating and manufacturing the best automotive valves in the world, you can be certain that there is currently no better replacement valve available. Forge's recirculation valve features a greater flow rate than the OEM Bosch valve, as well as a faster response time, due to its revised design.

⭐ 10/10, replacement for my stock 1.8t mk4 Golf DV, build quality is over the top ⭐

⭐ Great bit of kit, well made, easy to service ⭐

⭐ I bought the FMDV008 and the quality is outstanding from the packaging to the product itself, really is a piece of quality kit, easily fitted with the simple instructions included.... and it really does improve the performance ⭐

By using the associated service kit (FMDVSK), as seen below, the life of the valve can be extended, and the performance can be maintained. With a lifetime guarantee, you can be sure the valve is reliable for your car. 

It is fully customisable to fit your application with two uprated springs provided in the kit. Forge Motorsport's improvement on the original valve has a compact design, meaning easy fitment under the engine cover. The valve is assembled with a 25mm side pipe, and the vacuum port on the top of the valve is 6mm in size

This is a superb product. I have a mk.1 Audi TT roadster, 150 version, which I have had remapped to 190(ish!). Following this, mid-range power delivery was lumpy, and there was a flat spot at 3500rpm. Before removing the new map I decided to give this replacement diverter valve a try. This was a great decision.
Straight from the box the Forge Motorsport diverter valve feels quality. Nicely machined, well packaged, with two additional springs, and the required fittings. Fitting it was straightforward, the instructions are fine, and there are Youtube videos if you need them. It slotted into the space perfectly, and all hoses fit snugly without drama.
The results are incredible. The lumpiness gone, the flat-spot gone, acceleration crisper, and overall throttle response massively improved. Quite simply a wonderful bit of kit, and should be included with every remap. Genius. Oh, and it looks great too!
As a side note, I didn't know what boost pressure my turbo was running at, so I fitted the DV initially with the green spring. Some of the lumpy throttle remained (although much improved), so I installed the supplied yellow spring instead. The result was remarkable, as I have described. A proper pressure gauge would undoubtedly be advisable for an accurate assessment, but some trial and error achieved a great result.

Really quality product easy to fit and the sound is great still subtle on a standard 225LCR but i imagine it gets louder with more boost

Got one for christmas with intake pressure comp valve, fitted this two weeks ago, and immediately noticed better boost.

Well packaged and includes everything in the box that may be needed.

Bought this valve for replacing a blow off on a Punto Gt, Forge does not have this valve listed for being compatible with the Punto Gt, but is being sold as a replacment for the original valve, so I have decided to give it a try, worked straight out of the box, after being installed the idle got back to normal like factory and car does not fail anymore, dont know if there are any advantages for the PGT by updating the spring but I guess for stock pressure there is not need. Awesome product works amazingly I could not be more satisfied.

Excellent first class service from Forge, delivered next day, packaged well can't complain.
As for the DV it's a quality made item supplied with everything needed for a direct fit without any modifications required.
Coupled with an open air filter it's worth baring in mind it's quite loud but certainly not as loud as a BOV.

I'm always happy to receive Forge purchases as the quality is excellent for the cost of their products.
I purchased a FMDV008 for a customers car and I know they'll be very impressed with how it performs.
Thank you Forge for a speedy delivery.

Great customer service and great communication and very fast delivery.
As for the product, I've not yet fitted the item but fantastic quality and great how they send you EVERYTHING you need
from on Feb 26th 2016
I purchased the Recirculation valve and Intake pressure compensation valve together. Delivery only took a couple of days and all was as dicribed and seemed to be of a very high quality. Fitting of the Recirculation valve was very straight forward. Not that I know it the diafram type valve (original fit) that I removed was not working so the throttle response was more crisp, slightly improved performance and less induction noise. The Intake compensation valve was not quite as straight forward to fit but after sorting the mounting of the valve plumbing it up was quickly done with the supplied fitting kit. Can't comment on reliability yet but with the guarantee I'm sure there will no problems.
I am very happy with this product and service and would recommend it. With the discount on buying both products together it is a must for any future engine power mods. :-)

Speaking of service, from order to delivery, all very fast and with amazing quality care!
in relation to the dump valve and after installation in my car, I am speechless, I am very satisfied with the final result!

Hi I'm Looking for a diverter valve for my Mini r56 1.6 N46, advice please? cheers.

Hi Monti, 

from what i gather the N46 engine does not have a turbo so you would not require a valve of any sort 

Hi i'm looking for a turbo recirculation valve for a renault clio mk4 2013 0.9 tce. would you be able to advise me on which one would fit my car. Thanks, Lewis


The product you need for your vehicle is FMDV15.

Hi, I have a mk1 Audi TT and about 10 yrs ago I bought the Forge diverter valve (007p) from yourselves which had always performed excellently; last year i bought the service kit again as i thought id treat it to a second service! ever since refitting though i have had flutter from the dv when taking my foot off the accelerator at low speed/ including when just blipping the accelerator pedal, but the car holds boost well at full throttle - the dv has always had the yellow spring fitted (with no additional spacers) as it’s stage 1 remapped and I wonder if there could have been a problem with the replacement piston/seals I received? Or if there is something else I can try to resolve this. Cheers Mr Nelson

N75 failure at point of service is an unlikely coincidence and, by the process of elimination, would have a look at the vacuum/pressure hose connected between the FMCL007P and N75 to see if if the seal and/or flow integrity of this hose is in order. Otherwise it will be worth opening the valve to see if one of the O rings (piston and lid) have been broken or pinched upon reassembly and closure of the valve.

Reference your quality of the service kit question the o rings are not checked as part of Forge Motorsport QC processes (sourced externally where ISO 9001 QC processes have been applied) but you will have likely noticed a size problem upon fitting these to their respective recesses, and the piston is QC checked against machined tolerances and assembly quality before packing and despatch.

hello . is ok for audi rs2 ? regards,

Please enquire by email to with an image of the stock diverter valve (the stock diverter valve might be the very similar 25mm ported Bosch type but some of them have an electronic solenoid incorporated into the body).

What is the OD and ID of the black pipe for the top which is supplied with the kit?

6mm OD / 3.5mm ID, typically connected to 4mm ID vacuum hose.

It's not really a question but more an FYI I'd like to provide you. I can tell you it fits perfectly on Clio mk4 2012-> 1.2 tce 120 and I'm really happy with your beautiful diverter valve. No additionnal noise, so it's really stealthy, and the throttle response is sharper, love it.

Thank you for the feedback. much appreciated !

Hello which colour spring is best for a 2001 Saab 95 2.3 SE? Thanks

If the vehicle is standard ( no ecu tune )  I would go with the green spring which is installed in the valve from new 

I dont understand why you need to change the spring. If it fit like the instruction, the spring only "fight" with the boost when gas is out, so only fight to vacuum, and this do not change after stage 1. If it fit reverse, on gas, boost is up and down of the BOV, but without gas, boost is under and vacuum over the BOV, so it may have more sense, itsnt it? I install yellow spring on stage 1 s3 8l, (240hp) and it does not sound like is discharging. Great product!!

you are correct 

Hello I drive an 1.8T (8N) running 1.3 bar of boost pressure and experiencing pressure loss; which spring would be best? Hallo ich fahre 1.8t mit 1.3 bar Ladedruck, welche Feder wäre am besten? Da manchmal Ladedruck entweichen tut?!

For 1.3 bar of boost pressure please fit the yellow spring. Please also see the full range of springs below for this valve specification and their related boost pressure range. 

Green - 5-15 PSI (0.35-1.03 Bar)

Yellow - 15-23 PSI (1.03-1.59 Bar)

Blue - 23-30 PSI (1.59-2.07 Bar)

Red - 30 + PSI (2.07 Bar +) – not included in the FMDV008 tuning kit.

Für 1,3 bar Ladedruck bitte die gelbe Feder montieren. Bitte sehen Sie sich unten auch das vollständige Angebot an Federn für diese Ventilspezifikation und den entsprechenden Ladedruckbereich an.

Grün - 5-15 PSI (0,35-1,03 Bar)

Gelb - 15-23 PSI (1,03-1,59 Bar)

Blau - 23-30 PSI (1,59-2,07 Bar)

Rot - 30 + PSI (2,07 Bar +) – nicht im Tuning-Kit FMDV008 enthalten.


Hi. I ordered this valve and service kit. I am going to mount it on my Audi a4 b6 1.8t 163 hp. ECU is remapped and generates around 1 bar. Am I supposed to use the standard equivalent spring (green)? Your faithfully Maciej Morawiec

Thank you for the order - please fit the yellow spring included with the FMDV008 valve kit as this is the appropriate spring for 1 bar of pressure.
