Do Leon Cupra's have an N249?

[unikarl]

Or an N18 either?

I keep reading that people change their N249's or N18's and their cars run better. My car has very uneven accelleration on part throttle and somebody told me it could be the N249 or N18 at fault.

It looks to me though that an N18 is only found on diesels and an N249 is only talked about on the Ibiza.

Can anyone shed some light on this please? Im completely lost.

I have looked on ETOS and cant find anything that says its an N249 for any car!

It has one.

 

[unikarl]

Cool,

Dont suppose you know where it is?????

I don't think the cupra has once from what I remember of robdons engine bay (unless its been removed). If you want to check for it trace the vacuum hose from DV (smallest hose normally on top) to the engine if it goes to a solenoid with an electrical connector (similar to the N75 connector) thats the N249

i thought they all had it to be honest... that was my next port of call if i had more boost problems.

 

[unikarl]

Pabs...Any chance you can get me a quik pic of yours so i can see if my engine bay looks the same?

if your car is throttle cable car, it dont have one, if it's DBW should have one, some people remove for better response

Does that really work?

Apparently was a mod on here by sim somwhere, all the n249 does is open the DV if the ecu tells it to..... more saftey crap!!!

My car is DBW and it definately does not have an N249. The engine code is APP.

Are there any other valves that adjust the boost on part throttle? When i accellerate gently, i can hear the dump valve venting slightly through the dynatwist, now im wondering if my DV is knackered but its a baileys one which is not that old.

Cars do my head in sometimes!

Just about to hit 95k now so its done a few though the problem has been there for the past 30k at least.

Looks like the turbo upgrade will have to be done
