Erratic Idle

Lol- I'm not the one coming across as a total cock

Huh - how can I be the one who is a 'cock' when I am actually posting factually correct info!  Oh, sorry, because I have shown up two major errors in some yank originated document, then that makes me one?

Seriously, I think you'd best look in the mirror, because you havn't actually inputed anything worthwhile into this thread, apart from taking a cheap jibe . . . hey ho . . . . 

listen T-T, there's no doubting your valuable input into this site but lighten up. Just because there are a great many users who don't have your wealth of knowledge nor experience doesn't excuse the level of arrogance you seem to demonstrating.

So what about the extreme level of arrogance by the certain other poster.  I have proven time and time again on this forum - I generally know what the fcuk I am talking about - and on the rare occasion when I do get things wrong, I'm happy to own up.

Maybe instead of getting out your big wooden spoon, go and read Hillers, and then explain how a crankcase can work on a vacuum!!!

T-T you told people to go read that Self study to see how the PCV system works. 

Then you basically say that what VW have written is wrong and your right. Make your mind up.

Yup, I did.  But then I honestly did NOT expect to find two major and fundamental errors in it.  But I have a whole stack of official SSPs, most from Audi AG in Germany - and none of them support what the yankie one states. 

Or do you also think that the oil pump is driven from the inlet camshaft too? 

You will be telling us next that you know more about the Space Shuttle than NASA does.

Erm . . . no!

Its the remap go and get your money back!!!!


Opps!  Be reading too much on certian Seat owners forum...lol

LOL !

Yeah, I was thinking that in the back of my head. Dodgy northerns

LOL T-T. I'm perfectly entitled to input into ANY posting on this forum - it's a public forum.

I'm not actually disputing your knowledge - quite frankly I don't know if you're right or it's total BS. I have limited knowledge in the field of engineering and automotive mechanics - something I had hoped to gain a little from frequenting this forum.

The issue may or may not be regarding the content - I'm not in a position to comment, hence I haven't. BUT I can take issue with the attitude that you have portrayed in this topic.
There is an elevated level of arrogance and intolerance from yourself with a hint of bully-boy tactics akin to that of "I don't care what the official documentation states, I'm still right, and you'd better f'kin believe me!!" - this is the impression being given

I personally haven't witnessed arrogance from anybody else in this thread - I noticed an elevated irritation aimed towards Sambo when the nature of advice was called into question...... this was then reacted to with further "i'm right, everybody else is wrong".....

Feel free to read back the thread - this is how it reads to a 3rd party

As for your last childish remark, c'mon mate, act your age.

Right back on topic. Luckily I have the print off which my VW tech mate gave me when a number of error codes were logged. I had all of them so the PCV valve was changed as a matter of course. This is from 'Elsapro technical service handbook'

Technical product infomation

Erratic idle speed, entry 08583, 04759 or 08825.

Customer statement/ workshop findings

Erratic idle speed. The following entries are logged in the engine control unit.

08583 P2187 bank 1, fuel measuring system too lean at idle speed

04759 P1297 turbocarger- throttle valve connection, pressure loss

08825 P2279 air leaks in intake system

Technical background

Leaking non-return valve in the pressure control valve.

There's also a picture of the PCV which is circled as part of an exploded diagram.

Any use? 

Like I say this didn't fix my irradic idle, but there was a fair bit of oil in the DV (which was then replaced and fixed the problem, multiple rip's in the rubber diapragm) which apparently is an indication of a knackered PCV valve. My car is an early 54 plate and the PCV I took off had a 2004 date on, so it was replaced with a modified version that VW strted to use later on in production due to the failure rate of the originals like I had.

Thanks for posting this up

This seems to be the cause of all our arguments.  Do I presume correct that Elsa are using the above term 'pressure control valve' for the valve which is bolted to the turbo housing (on the standard 200PS GTI)?  And then abbreviating it to 'PCV'?  Because the correct technical and 'textbook' term for PCV is actually 'Positive Crankcase Ventilation' - and this is very different to the valve which regulates the turbo boost, and is why I have been quite vherment on this issue (even beligerant, some might say).  And on the GTI engine, the 'Positive Crankcase Ventilation' valve is bolted at the top of the engine, on the front face of the black plastic camshaft cover - hidden under the engine cover.

There's also a picture of the PCV which is circled as part of an exploded diagram.

Any use? 

Can you post the pic here?

I fully agree with the oil in the DV, and the torn diaphragm (and this might be a good idea to replace it with the 'piston' valve from the newer TSI engine) - but I'm struggling to see how this can affect the crankcase PCV - because the PCV is basically just a glorified oil separator.  When SWMBO next lets me have her GTI, I'll pull off the covers again, and have a proper look at the hose routings and related stuff.

My car is an early 54 plate and the PCV I took off had a 2004 date on, so it was replaced with a modified version that VW strted to use later on in production due to the failure rate of the originals like I had.

So is yours an AXX engine, or the later BWA?  And do you happen to know the part number of the item which was replaced? 

[sambo]

I can't get the picture onto the computer as I don't have a scanner sorry. The pressure control valve which they talk about is 100% definatly the PCV valve which is also the positive crankcase ventilation valve  . It clearly shows the the PCV being the black plastic 'strip' which is held onto the rocker cover? under the engine cover by self tapping screws. I changed this part myself so I know the part. My engine code is an AXX as it's early.

As per the VW bulletin, the problem seems to be a failing non return valve in the PCV valve itself. Maybe this is the pressure control valve, so effectively a PCV  inside the PCV valve? 

The part I fitted has the part number 06F129101L. I can possibly get the part number of the part that was replaced tomorrow, depending on wether or not it is still in the garage, or binned!

Brought the wrong lead so couldnt get it VAGCOMed

Im away for a week or so next week so looks like it will have to wait till when I get back. Its nothing major anyways

lol dammit! Just realised I REALLY shouldnt have said that l
