Couldnt find a write up on here on how to replace / change the n75 valve on a mk1 leon so thought id knock one up
Not able to upload pics for some reason but when it allows me to i will.
First of all ive got a mk1 leon cupra 20vt engine mods are full custom built exhaust from turbo back built by prospeed exhausts in cardiff ( cracking company btw ), pipercross panel filter ( upgrading to sports cone soon along with direnza fmic ) dump valve, stage 1 mapped by performance engineering cardiff and bypassed the n249 valve aswell.
Anyways down to business first of all engine covers need to be removed and n75 located and next to the dump valve is a small unit with 1 electrical clip and 3 hoses attached to it.
Remove the silver locking clip from the connecter and keep safe and unclip the electrical sensor.
Pull the hoses off but you MUST remember wich hose goes on which extension from the valve as there are 3 and you dont want to get them mixed up.
The long piece of the new valve goes into the big air pipe running off the filter
The other two must be put in the right way around best to colour code or mark then up somehow i just used a marker and wrote s and m on for small extension and medium extension of the valve.
At this point its a good idea to have a few jubilee clips to hand or cable ties to secure pipes onto new valves preferably jubilee clips for a stronger hold.
Putting the correct hoses on the correct extensions put it all back together and tighten all jubilee clips and replace the locking clip of the electric connector.
Job done.
Hope this helps i know its not the best without pics but its a start hopefully can get some pics up soon
