Cupra - VagCom faul code 08567

[redcupra07]

Hi all,

I have had the engine management light coming on in my car intermittently for a while now.

The following fault code is what appears:
08567 - Bank 1 systems too lean off idle. P2177 limit reached - intermittent.


The car is a completely standard 07 reg Leon Cupra.
It drives perfectly despite this fault code and it does not seem to be causing any issues.

However I want to sell my car and do not want to sell it with this fault code.

Has anyone had this fault code appear on their cupra and if so, what was the solution please?

Please note that I have no mechanical knowledge so any pointers will be passed on to my local garage.
It is them who ran the diagnostic for me and they said it could be any one of a number of things causing the fault code. They said as the car is driving fine, it isn't worth looking for a solution.

I am happy with their advice while I keep the car but of course I feel as though I need to resolve it before selling.


This is the RossTech page on the fault:

From my googling, this engine has a MAP sensor, not a MAF sensor. Would it potentially be wise to replace the MAP sensor? It's less than £40:

I've heard about cleaning MAF sensors etc but replacing this MAP sensor would be ideal if it solved the problem as the sensor is cheap.
Any idea how many hours this would take to replace please? Just so I can get an idea of how much the garage would charge.

Thanks in advance.

Just had a quick read of your post and the link to the ross tech site,your car has both a maf sensor and a map sensor im not so sure how common they are to go wrong on these engines though.
Personally i would get the car checked at a vag specialst i know its not ideal but it could work out cheaper in the sense you wont be replacing stuff in hope that it fixes the problem.
Looking at the solutions it could quite easily be a fuel injector not injecting the correct ammount of fuel or something like that which is why i suggest going to a vag speacialist as they will be able to do tests on the possible causes which saves chasing a fault around in circles.

Hi mate, It could be a number of things as they say.

I don't think it's worth replacing any sensors yet as all of them should give you a fault code if they had failed. When a engine is running lean and there are no other codes, then 95% of the time it's down to a split hose letting extra air into the engine. That extra air hasn't been accounted for by the MAF/MAP so it makes the mixture too lean.

Have a look at all the hoses you can see and check for splits. It will more than likely be one of the smaller hoses that carry vacuum, or the PCV hoses (Positive Crankcase Ventilation, i.e, the system that vents oily fumes around the engine) that have split and are letting extra air in.

If there are no obvious splits, then as said above, go to a garage that specialises in VAG motors and they should be easily able to find it, or if it's not a leak then easily identify the real cause of the code. That will save you a lot of cash in the long run, as the garage above should know that a lean code is usually something simple and not just start taking guesses at various expensive componants etc which will probably be their next suggestion. There are plenty of garages out there that are great for doing a cambelt or swapping suspension parts etc, but give them a engine management issue and they're lost.

Edit: if you haven't already done so then i would highly recommend changing the fuel filter. They are fairly cheap (£15ish) and easy to replace, if that is clogged then it would also cause the engine to run lean, especially as higher revs which is what that code would suggest is happening.

 

[redcupra07]

Thanks both for your replies.

Sent a couple of local VAG specialists an email so will be taking it in to one of them when they reply.

In the meantime, Matty, that sounds like a good idea to replace the fuel filter as it hasn't been done for quite a while (at least in my 26 months / 25K miles of ownership).

I can see that is something that I'll need a garage to do as I certainly don't have the knowledge!

Just out of interest though, I had a little look on eurocarparts and even when I type my reg in, some of the filters look quite different to each other. Do you recommend one in particular? I may get in touch with the chap who works for Sere as I want the correct one:

My other question is regarding looking at the hoses. I will have a look tomorrow when it's light but do you have an engine bay diagram pointing out where the PCV hoses are please? Or can you describe approx where the hoses are?

Thanks for your help so far!

 

[redcupra07]

Anyone else got any ideas on this please? Particularly regarding the two different fuel filters I have linked above. If someone can clarify why there are two different looking ones which are both recommended and which one is the one to go for, that would be ideal.
I can then get the fuel filter sorted this week and have a look at the PCV hoses and then get hooked up to a VCDS reader again.

I think this is the one you need or comparable on ecp:

Sorry for the late reply buddy, don't often read the mk2 section. I'm not sure of the correct fuel filter or pcv hose layout on the Mk2, i've only ever owned mk1's so far. If you go to the branch of eurocarparts etc, then they will get you the correct one using your chassis number etc if needed.

Edit:If you know your engine code i'll look the pcv layout up for you on elsawin

 

[vfr400racer]

You need one with 6.6bar regulator. Not 4bar or older 6.4bar. Ufi or mann wk69 is one you need. Or seat pn 1K0201051K

Cheers for your replies. Got it booked in for Wednesday so will keep you updated. Hoping it'll be something this simple!
Matty, engine code is BWJ.

No worries mate, i'm sure it will be either the fuel filter or maybe a air leak. Had a look for PCV diagram for you, but there isn't one on elsawin as far as i can see, typically it has everything but that.

 

[redcupra07]

OK so time for the update!

Took the car to a local VAG specialist for a fuel filter change and gave him details of the fault code.

He changed the filter, cleared the fault code and took the car for a drive. Fault code has remained off so this seems to have solved it! Makes me feel a little better about advertising the car now.

Thanks for all your help chaps.

No worries mate, glad to hear that it was a cheap fix for you

Sorry to be Mr Doom and gloom. but i wouldnt get too carried away untill the light stays out for a bit longer than one day.

Ive thought id fixed things in the past only for them to reappear. Hope you have fixed it tho

That's a fair point! On the plus side, I needed to have the fuel filter changed and he didn't charge anything to run the diagnostics before and after.

 

[OldManPooley]

Fingers crossed bud.

 

[redcupra07]

Sad news... OldManPooley - you knew best! Light has come back on 150 miles later.

However, on the plus side, fuel consumption has definitely improved since changing the fuel filter so that was definitely money well spent.

I'm a little confused by this VAG specialist's comments though.
A few days ago when he carried out the work, he said that he scanned the car for the fault code and stated that "it was related to the front lambda sensor". I didn't question this at the time but surely that is incorrect... This 08567 code is surely nothing to do with the lambda sensor?
He said he cleared the code, changed the fuel filter, took it for a drive and it stayed clear (as it has for 5 days).
If the light came back on, I was to come back in and we would go from there - ie replace the front lambda sensor.

I am VERY reluctant to do this seeing as when I have read the car with a Vagcom reader, this 08567 code is the only one that comes up...
Does anyone know if this has ANYTHING to do with the lambda sensor?

My next step is to locate someone with a Vagcom reader to re-read my fault code for a beer token. Then I may take it to another "specialist".

UNLESS, someone can confirm that actually fault code 08567 does have something to do with the lambda sensor?

It's a highly unlikely scenario that when he scanned the car, fault code 08567 wasn't present and instead, there was a lambda sensor related code?!

Cheers

P.S: Anyone living near SW4 with a vagcom reader, give me a shout.

 

[OldManPooley]

Bummer mate. I would have to agree that it doesnt sound like it would be the 02 sensor.

 

[vfr400racer]

I doubt o2 sensor too. Could be slight vac leak check oil cap and dipstick fully in properly as stupid as it sounds. Or pcv issue? A more comprehensive scan with vcds or carista would be good to shed some more light on it. It cant be very severe whatever it is as it doesnt affect driving at all in any situation? Just throws a cel light?

 

[mty12345]

Hi again mate. Sorry to hear that you're still having issues.

The front O2 sensor is very much related to that code in a way, as that's the sensor the engine uses to determine if the mixture is too rich/lean. IMO it COULD be the cause...............It's possible that your mixture is fine and the O2 sensor is falsely reading it as lean.

You'd usually expect to see a code for the sensor itself, but that tends to only happen if it's completely failed, or if the reading is completely unbelieveable to the ECU. If the readings are only slighty out, then the ECU could think that the O2 sensor is ok, and that the mixture is the problem instead.

 

[redcupra07]

Thanks for that reply Matty. That has been really helpful because at least it explains why the mechanic said it might be that.
I'm going to someone's house tomorrow to get a full VCDS read out.

In the mean time, I posted on pistonheads too and a chap on there agrees with you that it could be an air leak. I just want to find a competent local garage who are able to test for this!

He also suggests MAF sensor. I think I'll HAVE to message the helpful chap at Sere to give me the MAF part number as I can't find it for the life of me.
I know what a "standard" MAF sensor looks like. Does the one for this engine really look like this?!:
