1.8t persistent p1137 bank 1 additive too rich, lots of steps already taken now stuck

[sonic_vi]

Fair enough - might be worth getting that done anyway then.

I'm not saying that shes perfect with no leaks i just meant as its pressurising to the right boost it would be unlikely to throw out the adaptions by more than the 10%......although i could be wrong. Every day is a school day as they say lol. Thanks for the help.

Good shout on running with the maf disconnected.

Thanks Bill, and sorry Sonic for the duff info on the boost meeting request thing. I'd have thought if it was leaking boost enough to throw fuelling out then it must be unable to meet request. Boost leak test always worth doing from time to time anyway, I've found a couple of small leaks on occasion that I never knew were there...

EDIT - my money is also still on the MAF

Yeah I was kind of thinking the same thing - I have had a boost leak on my old cupra, pancake pipe popped off a bit) and even that didn't throw things out to the extent of an EML and that was down on boost

Bill is the guru though !

I am gonna get stuff mapped today and then I am gonna pilfer the MAF off the aforementioned VRS and then log again and see if things change.

Would also in theory throw the CEL on the octavia too if my MAF is fecked

Cheers again guys

yes indeed you could be wrong dude... sorry. Not trying to be an arse, but I do these cars every day and 90% of them have leaks completely unknown to the owners


Unfortunately you just cant use its holds boost request as it not having significant leak.. It just is'nt how it is.

usual suspects are associated under inlet manifold and PCV piipes. rot and split.
Tell tale is look for pipes which look "oily and smeggy" as that smeg came out of somewhere.. It should be bone dry and at worst a little dusty, never shiney and oil damp.

 

[ibizacupra]

limits for throwing MIL are quite high...
032 adaption will show its "need" to adjust for something much earlier.. and only when +/- 25% limit reached will it go MIL

 

[sonic_vi]

Haha thats fine. Nothing like a bit of misguided logic built on unfounded assumptions lol

Regardless i'll get a leak test done but if i can at least get shot of the eml for now i'll be happy(ish)

I am going for a remap at somepoint so will need it checked before then anyway

OK EML came on again today after clearing yesterday so definately something consistently out

[sonic_vi]

Btw i cleared the fault code before the run. Just the standard too rich. Nothing else

 

[sonic_vi]

also have unhooked the MAF now and am convinced its that as poo off a shovel doesn't quite cover how much quicker it is. Also indicated fuel economy shot up a bit too - there are certain sections of road that I cover every day and I know what it normally does at what speed and it was up.

i wondered if the extra speed was due to the ESP being switched off so i plugged the MAF back in, cleared the codes and tried again with ESP off and its not as good as with the MAF unplugged.

PLEASE GOD let it just be the MAF and does anyone know what ECP are like about taking stuff back without a reciept? I have the order number they should be able to track as it was a click and collect.

[will130787]

I have only skimmed through because I am short on time today so apologies if this is already covered. I have the same problem and it is down the a split hose under the inlet mani causing an air leak. Is it that?

I have a LCR btw

 

[sonic_vi]

Not that i could see. I was firing wd 40 around that area to see if the engine note changed and i didnt notice anything.

 

[sonic_vi]

Also would a pcv leak not cause a lean condition rather than rich?

 

[traumapat]

Just to mention I tried carb cleaner around the pipework and engine ignored it... smoke test revealed 1xboost and 3xvac leaks. I don't think these leaks are apparent at idle. Only seem to appear when theres pressure/load applied.

I'd smoke test it just to rule it out before chasing sensors.

Fingers crossed it will become obvious.

Yeah hopefully. Its not gonna cost me to try another MAF as I can borrow a known working one.

 

[sonic_vi]

Ok need some more help.

Been running round with the MAF unplugged for 3 days. Ran codes yesterday and had too rich intermittent. Figured i hadnt cleared the codes since unplugging the MAF. Cleared codes, Run round rest of yesterday and all today (about 140 miles) and i have too rich code again when i ran the codes 5 mins ago. Any ideas?

Did the logs posted give any pointers?

 

[8bit]

Logs say the ECU is pulling out as much fuel as it can but it's reaching its' adjustment limit of 25% and giving up. MAF readings look ok if a little low to me, peak airflow on your 4th gear run of 139.39 which is enough for about 174bhp. I'd suggest as Bill says, likely you have some boost leak somewhere. Need to get it properly tested, ideally smoke tested.

 

[sonic_vi]

Cool i'll get it checked

Get it booked in at awesome
