SAI fault code

[SidewaysCupra]

Giving the car some welly in the snow today and the "check engine" light came up on the dash.

Put the car on vag-com when I got home and it came up with:

16795 P0411 Secondary Air Injection System: Incorrect Flow Detected

I have done a search and found that this is a pretty common problem. Most of the threads i've read suggest a split hose as the likely culprit. Problem is I have no idea where to begin looking.

I know that the best thing to do would be to replace all the hoses but given the weather outside i'd rather leave it for a sunnier day.

If someone could show me the hoses that are connected to the SAI I would be gratefull.

clear it sometimes these faults crop up, if it it comes back have a look under the bonnet!!!

I had this a while back, cleared it a few times but kept coming back. Turned out to be a split vac hose

 

[SidewaysCupra]

Can you remember whreabouts the split hose was?

Around the turbo intake pipe or on top of the engine?

 

[cupramillo]

Got a garage to fix it as it was in for a service at the time. But i think its along the top of the engine, near where you do the n249 bypass. Not 100% so will need some one else to confirm.

Looking at your sig, we have nearly identicle mods

had this twice now in about half a year.

yesterday was second time. Its because I didn't remove the SAI, I merely blocked off the vac pipe. 2 codes in half a year isn't too bad I guess.

Even people with the SAI totally removed and with resistors n place still get this code sometimes.

Yep. I have removed the lot and still get the code every other week

clear it and dont worry about it

 

[Damoegan]

clear it and dont worry about it

I do and dont

 

[mr_D]

i know you do. just on about to the thread starter lol

Ha ha, get you now lol

 

[mr_D]

lol

all the time

the code is starting to become a part of my life now lol

 

[mr_D]

have you used a resistor on it?

 

[pj1985]

Its just crappy Ibiza ecu.

 

[cupramillo]

lol i know, supposed to be a clever adaptive ECU then it gets stung by the same code time after time!

 

[pj1985]

Thing is what detects the SAI flow as being incorrect? There is no sensor for it so it must be calculated by the ecu from some tables somehow but what ones!

 

[p34ch3y]

have you used a resistor on it?

yes

Thanks for the replies everybody.

I guess i'll leave it as it is for now. Change all the tubing for silicone jobbies when we get some decent weather.

Cleared the fault code last night and it didn't come back on during the drive to work today.

I guess that's part of the "charm" of Ibiza's. Another irritation to add to the list.
