Diverter/Recirc Valves part#'s

Post by groupA » Mon May 13, 2019 9:26 am

Hi Gents,

Anyone have part numbers for the diverter valves? im aware they are a integrated with the lower section of the airbox. Unfortunately my indie only seems to be able to find a price for a full airbox replacement which is 400 pounds per side


Thanks

hi - if recir valve is indeed an issue, this would be your best option - https://www.forgemotorsport.co.uk/Turbo ... --756.html. Note you'd need two valves (one for each side). A job requires some DIY as OEM ones are integrated in the air box lower assembly. There is a really good thread on this forum that talks about How to.

Hope that helps.

As above. Your indie is correct, all part of the lower box on these cars. I replaced mine with the Forge items.

Thanks for the responses guy's. Does look like forge items made to fit is the best option

Reason im looking at replacing the valves is due to a code thrown in relation to the N249 valve. Have already replaced the N249 so figured DV's was the the next troubleshooting step. Any ideas?

Where did you get the N249 valve from, I was led to believe they were on back order? Have you checked for vacuum leaks before replacing the BOV's? Its not a simply job and most garages won't want to do it as its a 'modification'.

Im in NZ but the N249 came from the fatherland (was early Feb so must have still been available at that point). Will start working through the vacuum lines thanks for the advice
