I thought maybe the part looked the same.

Ah well worth a try.

I had a look at this and I *think* you could disconnect the small vacuum hose (comes from the inlet manifold and goes to the N249) and use an adaptor to attach it to your DV hose, or just replace the whole thing to connect directly to the DV

I'm had mechanical malfunction show up on mine once as well, wasn't sure if it was just a glitch or not

do you find sometimes that the power seems to disappear and then come back again but not as strong, almost like you're lifting off the throttle really quick and going back on?

the n249 valve on the cupra is under a steel plate at the frount of the engine.i have taken all the pipes of it and put a T piece in instead but left it wired up the car is going fine much smother.

i always thought it was somewhere near the dipstick holder on the leon.... like ninjabadger said.
