[mulletman]

ok, any advice would be great please guys, just had my 007p dv, miltek turbo back forge tip and re map done and have been happy up till now, the car keeps going into limp mode and was wondering why this might be happening, please dont ignore this as im starting to get annoyed with the bloody thing!!! thanks all, daz

You need VAG com dude.... come over this way and ill be more than happy to plug you up.

 

[helms]

Russ, where do you get Vag com from? How does it work?

 

[cupra_matt]

When does it go into gimp mode? Under load? possible overboost fault.

 

[mulletman]

yeah under load! for example i was booting it up hill and it did it, what could this be, russ thanks for the offer mate i might take you up on that

 

[Russ_20vt]

Underload could be either your car achevining to much boost or to little boost.

To much is the N75 vavle playing up

To little is a boost leak or the turbo not being able to produce enough boost.

or

It could be a intermittent fault with the maf.

 

[Russ_20vt]

oh and we can always meet half way.

 

[mulletman]

your a star mate, ill let you know, it would be good to see the car again, i miss her a lot, and youve made all the right improvements to it too,

 

[mulletman]

btw ive just replaced the n75 when the rest of the work was carried out, theres two valves on top of the head that the guy said were faulty, what are they and could this be it? cheers guys

 

[Molehill_Mike]

Is N75 replaced correctly?

Hooch had this problem, N75 was incorrectly fitted when replaced...

...Just an idea

Mike

 

[ian_jobson]

yeh which n75 was fitted?

If its teh C then it fits the same way as the one that came off (if that was original)

If its an F its opposit way round on mine, also what map have you had done as some maps dont like other n75 valves?

F is the opposite way round?

Done a change over a few times on another Ibiza between an F and a C... fitted both the same way??



True tho, REVO is def written for use with the F valve.

[ian_jobson]

hmmm thts strange both myself and sum1 else on here found tht changing the F around solved our limp problems... worth a try worst tht'l happen is itl still go into limp mode as far as im aware

 

[mulletman]

the re map i had was a generic one, thats all i know really. but the guy is good, no botch job, and i did have an f n75 valva fitted so i will try this, thanks guys, daz

Hello Mate,


It may be worth a shot just reseting the ecu.

Disconnect the -ve battery terminal and leav it off for 15mins.

Re-connect and turn the key so that the key is in the on position but engine off for two mins. Then start the engine.

Do this with the engine stone cold.

This will do two things. It will A reset the ECU so any adaption made before the engine changes can be re-learnt.

B, this will also do a throttle body alignment which will will always help pedal response.

Good Luck.

 

[mulletman]

thanks mate, the stuff was fitted by a professional guy though, and he did say that the two valves located on top of the head were faulty, could it be these valves

 

[TBCupraT]

N75 Valve + dump Valve.

We pretty much diagnosed these were faulty when you came over.

 

[mulletman]

ive had them both done though mate, within a few hundred miles,

 

[TBCupraT]

Might need to measure you M.A.F to see what it's flowing.

If it's not reading low it will send it into limp. Been there mate. Twice.

 

[mulletman]

these cars are great always keeping you busy, ive got a good mind to sell it because of its little probs, i mite get a leon instead,
