Adaptation reset???

[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?

 

[Martyn]

Yup, sounds like it did the full reset and the TBA. Does the car overboost then go into limp?

 

[ian_jobson]

nope, theres another thread in this section called "fitted mew maf but..." that explains in detail, any help would be appreciated!

If it reset everything how comes i didnt need a radio code?

 

[flashbsd]

because the radio isnt removeable so theres no point in a code, nobody's gonna nick it!

 

[ian_jobson]

fair comment.... god im dumb

 

[ian_jobson]

the buzzing didnt stop before i turnd it on tho, carried on when i turned ignition back off, may hae been the fan cos 20 mins is a fair ol time???

 

[Martyn]

The TBA only takes a few mins so i'm pretty sure it would of finished matey.

First thing i would do is clear all the fault codes off and see which return

 

[ian_jobson]

the 17965 - Charge Pressure Control: Positive Deviation fault means your car is overboosting, ie your actual boost is exceeding your requested boost. Maybe a faulty n75 valve?

 

[GaryM]

I believe that the only way to realign the throttle body is with vagcom, the noise you hear when reconnecting the battery whilst the drivers door and bonnet are open does come from the TB but it isn't realigning.
I've read many posts on different forums backing this up.

the 17965 - Charge Pressure Control: Positive Deviation fault means your car is overboosting, ie your actual boost is exceeding your requested boost. Maybe a faulty n75 valve?

so does tht mean itd limit it to 6psi to control the problem?

i want to get a new N75 valve, mines an F. of anyone knows where i might find one at a decent price, itd be appreciated!

 

[jambojones10]

try logging your n75 duty cycle. log block 118 on vag-com, also log block 115 , tells you your requested and actual boost. Do a run in 3rd gear from about 2000revs to redline

 

[Martyn]

Just pop to SEAT mate to get a new N75 and yes overboosting will cause limp mode (5psi).

 

[Simon L]

When i bought a new MAF off some joker company on eBay, it sent the car straight into limp with a "positive deviation" error.

 

[ian_jobson]

was doing it befor i changed the MAF too, the maf cleared one fault so thts working, i dont know how to run logs guys, my local seat it pants only has a parts desk in office hours.... i work office hours!

would limp mode not through on a light on the dash?

 

[Martyn]

Na, it's only 'soft' limp mode so no check engine light.

 

[ian_jobson]

fair enuff, really appreciate ur help fella's now to track down an N75f
