I fitted new MAF but...

[ian_jobson]

im still having problems

Fitted it, cleared the errors with vagcom.

took it for a spin after letting it warm up i boosted for the first time and as i slowed to a stop it cut out! it did boost to 8 like it should do (where as its only been 6 for those who haent read my other thread.) it started up fine again and boosted up to 8 again fine... then... it started stopping at 6 again.... cut out once more. left it off, started it again a bit after and its running ok (not cutting out) but still only raising to 6psi...

help...

What codes are you getting? DId you fit the new Temp sensor?

 

[ian_jobson]

fitted new temp sender not had a chance to ag com it yet but i noticed tht 1st boost after car warmed up it gets to 7/8 but the cuts back to 6 and never goes back again until car turned off and on again then does it once and so on.... n e ideas? when it hits 7/8 it immediatly drops to 6 as if teh cars thinking "sod tht" and dropping

n75 valve would be worth a go?

 

[ian_jobson]

how would i know which N75 i have? c or f?

 

[Copra]

there is a whole host of info on it on scn. do a search, but be warned, there are LOTS of posts to read through

 

[ian_jobson]

tonight it started boosting properly to 8 for a bit then for no apparent reason stopped and went back 2 6???

 

[Copra]

try the n75 matey. its a boost control valve

 

[ian_jobson]

tried resetting ecu earlier, left battery off for 10 mins but when reconnected the radio worked fine (didnt ask for a code) and primed ignition and got a buzzing (thought it was the TB re alligning) but it went on for at least 20 mins till i figured it might be the water pump and started her up. once warm gave her sum welly and it boosted fine.... for about 3 mins then reerted back down to 6 again... did i actually reset anything?

 

[Copra]

all you will have done is reset the ecu, if there is a mechanical fault (ie a faulty component) you wont have fixed it! have you read the fault codes?

 

[Martyn]

Standard N75 for the mk3 ibiza is a 'C'.

 

[ian_jobson]

mine states F on it.... its grubby enough to be the original part too.... gonna vag com it again in a bit but no idea how to do logs etc lol

 

[Copra]

thing is with n75 is it wont show faults.
they are cheap, im sure someone on here has a spare one, its a 2sec job to change it and are quite common to fail. its worth a go

 

[ian_jobson]

im sure some one with more knowledge can point you in the right direction there. did you clear the codes? if so, did they come back, and again, if so, how did the car drive with the codes clear? i wonder if your car has the revo software on it, and is in stock mode? worth trying to see if a sps device works? just a thought.

 

[ian_jobson]

martyn translated for me its overboosting and sending into soft limp, cos its fine just after a reset and clear codes but then goes back and the positie boost deveation comes back

 

[Copra]

i guess there is a chance the actuator has been fiddled with. how long has it been doing this, what is the story behind it?
did i mention you should try n75 valve?!
