      Several Citroens, Ibiza ST (6J8)
      05-31-2012 06:29 AM #1
      I have an Ibiza 6J ST, MY2011. Last evening the glow plug light started to flash while drive about 100 km/h on CC. The car was stopped and the engine turned off. When the engine was started again the light didn't flash anymore.
      This morning I hooked up the car to VCDS and this error showed up, even with aggressive-mode turned off. I went to the dealer who checked the engine with their VAS software. It did not recognize the code either!!! The only thing they could do was clearing the error-log.

      We're going on holiday with the car this Saturday. Has anyone seen this error before? Can I expect trouble with the car or can I sleep without worries?

      Just an update for those who wonder:
      I've driven 3000km since the error occurred and the problem has not returned (yet). Nor does the car seem to drive any different. The ride to and from France (about 900km in one stretch, 10 hour drive...) went smooth as well.
      So the error can probably be safely ignored

      I've never seen a 15604 error code before either.

      I went to the dealer who checked the engine with their VAS software. It did not recognize the code either!!!
      Then I don't feel so bad about VCDS not knowing what it means.

      What you have to understand with these newer ECUs that use the UDS/ODX protocols is that the "raw" fault code coming from the ECU cannot be interpreted without looking it up in an ECU-specific "dictionary" first, and if the ECU manufacturer doesn't include it in the dictionary they give to VW for that ECU, no scan tool will be able to tell you what it means.

      @Uwe: don't get me wrong. It wasn't meant as criticism on VCDS. Just tried to inform readers as complete as possible and hoped someone had seen the error before and knew where it came from.

      Hey, I have a 2011 6J Ibiza ST too, same fault code has come up for me, did you ever find out what it might be?
      How many km on average would you get from a full tank of fuel?
      Cheers,

      Still no idea what it was. The car has performed without error since...
      On average it consumes 1 liter for every 24,something kilometers.

      Today the glow plug light started to flash again, just when I turned into the street where I live. The displayed said 'STOP ERROR' (blinking to and only for a short time). Parked the car, shutdown the engine, removed the key, waited a few seconds and started the engine again. Flashing light was gone.
      Just hooked it up to VCDS, same error... Guess I'll visit the dealer sometime this week. Maybe their database has had an update. (Didn't clear the code).

      To be continued...

      Hi, This Start Stop Error also happened to me, I believe the ECU doesn't allow the start stop system to operate under certain fault conditions, I think it only happened when I had the engine check light on for me.

      *Edit* - The more I think about it, it was actually the flashing coil light that caused the error message.

      Along with the unknown error code (which as you can see occured twice)
      15604 - ROD - Unknown Error Code
      - F4 [008]
      Intermittent - Confirmed - Tested Since Memory Clear
      Freeze Frame:
      Fault Status: 00000001
      Fault Priority: 2
      Fault Frequency: 2
      Mileage: 0 km

      I also had the following.
      16396 - EGR Valve (N18)
      P0403 00 [175] - Malfunction
      MIL ON - Confirmed - Tested Since Memory Clear
      Freeze Frame:
      Fault Status: 00000001
      Fault Priority: 4
      Fault Frequency: 24
      Mileage: 69062 km
      16395 - EGR Valve (N18)
      P0403 00 [175] - Malfunction
      MIL ON - Confirmed - Tested Since Memory Clear
      Freeze Frame:
      Fault Status: 00000001
      Fault Priority: 3
      Fault Frequency: 21
      Mileage: 69070 km
      The EGR valve was replaced by my Seat Dealer, however they seemed to ignore the following fault, which has not happened again for me since the EGR valve replacement, also I haven't had any further coil or check lights since.

      15886 - Fuel Injector #3 (N32)
      P0269 00 [008] - Contribution/Balance Fault
      Intermittent - Confirmed - Tested Since Memory Clear
      Freeze Frame:
      Fault Status: 00000001
      Fault Priority: 4
      Fault Frequency: 2
      Mileage: 69721 km

      I do however have a concern that I am not getting the fuel economy that I would like.
      I have roof bars attached an a small set of ladders on them most of the time, I also have a reasonably full boot continuously as I use my car for work and carry my tools around.

      I had asked my dealer if there was a software update for my ecu but they weren't terribly helpful, only to say that if there was one it would be listed in a recall notice for my VIN, which there supposedly wasn't.

      I believe the software version is 7639, I think I have seen revisions in the 8XXX on other forums for the same engine, both Seat and VW cars.
      I thought maybe an update could help fuel economy, but I might just have to do some further tests with an empty car to see what the difference is without the weight/air drag.

      Ok, So I spoke too soon.
      The unknown fault has happened again, literally minutes after I posted here the coil light started flashing and when checked with vcds I got:
      15604 - ROD - Unknown Error Code
      - F4 [063]
      Confirmed - Not Tested Since Memory Clear
      Freeze Frame:
      Fault Status: 00000001
      Fault Priority: 2
      Fault Frequency: 2
      Mileage: 0 km

      Readiness: 0000 0000

      Unfortunately my dealer can't take a look at the car until Thursday, and when restarting the car the coil lights gone out.

      I haven't check but I suspect "limp mode" is still active from the original scan with the light on.
      BAHH!
      Such a pain!

      Well at least with the 1639x and 15886 error you know what's wrong
      Odd the 15604 occurred just after you posted, does your car read you forum posts

      It was not so much as a 'Start/Stop' error but more that the display said 'STOP ERROR'. My engine did not go into limp-mode though and it ran fine again today.

      Tomorrow I'll pay my dealer a visit, keep you posted.

      Hmmm,
      Thats starting to make me wonder what was actually shown on my display.
      I could've sworn it said "Start Stop Error".

      I had attempted to set cruise control just as I noticed the coil light start to flash, this could have been totally coincidental.

      I don't hold too much hope in my dealer resolving this as I believe this unknown error had also occurred within several weeks of my purchase of the new car.
      When checked at that time they told me it was a "Body control unit/module" and couldn't really tell me what was wrong so other than clean a few connectors and hope for the best didn't do much.

      cheers.

      The dealer has sent the error code to the importer (is that a valid English phrase?). Maybe they know something their VAS-system doesn't.
      The dealers mechanics guess is that it's a software glitch and that the ECU sw should probably be updated. (which takes about an hour...) It still has the original sw, version 7638. Rev 9512 was available this February.

      The Ibi is quiet sensitive to head wind, the ladders on top probably don't do the fuel consumption any good.

      Got my car back tonight from the dealer.
      I pretty much asked for the software update and thankfully they obliged.

      Version 9522 - Sounds pretty new if 9512 was from Feb.

      Lets hope it fixes the unknown fault.
      What I find interesting is the software update didn't reset anything, trip computer or my long adaption adjustment increasing lane change indication from 3 flashes to 4.

      Hopefully it might help the fuel economy too, just about to fill up tomorrow morning so we'll see.
      It's a pity there isn't a change log for software updates.

      Do you have Roof Bars on your Ibiza?

      One of the sw updates fixes cold engine noise by injecting a bit more fuel. (pre-inject?) So in theory it would use more fuel
      I guess the engine has to get used to your driving style again so you can't say anything about fuel consumption the first, say 1500km.

      The settings you mention aren't in the Engine BCM so they should stick.

      And no, I don't have Roof bars.
      Tire pressure has some influence as well. Front tires at 2.9 or 3.0 PSI, rear at 2.8/2.9 (depending on the load).

      Word from the importer was a sw update for me aswell. Hope it fixes this. (Get back on this in a year or so )

      Today the ECU sw was update to 9521 (odd they didn't have 9522 available). Hope this helps.
      (wasn't free of charge BTW)

      FYI
      I haven't had the 15604 error since the sw update. Full consumption was worse the first few months but got better since then. Engine runs more silent as a plus. Last visit at the pump it ran 25km/liter (58.8 mpg). Not bad IMHO.
