Kristianskaffe's MK7, 2.4 TDCI, RWD

[Kristianskaffe]

As you see, the actuator does some small movements but falls back.
After I turn the ignition off, I have a high pitched electrical sound and as you can hear, also some funny electrical noise at some point.. Could some like a loose connection.
The ground wires under the ECU I have moved and made new. The one under the coolant I have also done. In the diagram there is suppose to be one more, but if that's the fuse box, I guess I'm all clear.

As all the wires beep, then what..

Well... I have a local car shop around the corner and I have now given up.
They say, that they have a guy he who is an expert in the electrical stuff.
I think I'll give it a shot as this is not fun any more

[Kristianskaffe]

oh my... Never ending story...

Now I have visited the car shop... They said to come back when their electrician returned, but one of the guys could not resist to give it a try.
He said that he did some old school "investigations" and that in his best opinion the turbo works, and also the electrics ...and by hand, he could feel the pressure in the turbo pipes...

The gave it a lot of throttle and it made lots of black smoke but also a BIG BIG black stain on the ground, which to him indicated that the EGR is bad... maybe the MAP sensor too...
He said, that if he was to fix it, he would change the EGR and maybe the MAP-sensor...

After he did all this... acutally he also turned the ignition on and off while the engine was running, and then he could tell the the turbo was working... But afterwards I had error codes relating to the EGR, which I never had before! I also went into limp mode, and my ABS and a whole lot of things went bad... I could not clear the codes, so only thing that helped was a PCM-update...
Damn, 3 hours lost again... or 3 hours went by anyway..

Could it be the EGR?
If so, can I test it by inserting the plate for blinding the EGR, before I just buy a new one... I have the plate somewhere, but did not install it, as I wanted to be sure that everything was running with no errors before remap and all..

Please...

You're not having a lot of fun are you..??

You can blank the EGR...but you'll get MAF and MAP fault codes.... possibly along with overboost/underboost fault codes and due to incorrect EGR air flows etc..

You think!

Screw the fault codes at first, if just the bloody van would start running properly!

I know I can blank it, but will it also be a way of telling if that's what's causing it.. I remember something about that the EGR should be OK before blank, but can't remember why or where I read it.

Thanks

Knobby will hate me for saying this but.......

Why don't you both do a data set recording of the pcm.
Maf
Map
Turbo
Egr
Revs
Temp
Etc.

Do warmups, Rev sweep, 1k, 2k, 3k, 4k, etc.
And compare.

I hate you... Not really...!

It's actually a fair idea...!

Compare before and after blanking the EGR?

Yeah...but I've only just started work here in Sydney...and I'm on me motorcycle today..!

It's 11 pm here and I have to work tomorrow... I dont know when I come around to it..

But thanks!

I seem to have lost the blanking plate in all of my stuff that's lying around. I'm normally quite a happy person, but the weather these days are killing me.
Nice and sunny for 5 min. and suddenly almost storm and horisontal rain the next minute... Meaning I'm packing this up in a not so organised manner So I hope I'll find it, as I'm going on a 400 km. drive on Thursday and my mechanic is right along the route. I'm thinking about installing the plate and see how it goes, as I don't have the time (at that time) to test everything.
I'm going back the 400 km. again on Friday and could stop at the mechanic to take it out if it's totally shite.
I'm found a new EGR at around 100 pounds which seems as a good bargain.. Just don't want to put in a new, if I can just blank it and call Martyn for his help and magic... Doing that anyway..

I really hope I´m over this soon...

[Kristianskaffe]

Then problem with overboost seem to have disappeared... As I think I just blew a turbo pipe on my 400 km. drive..

[Kristianskaffe]

Hi boys,

Nothing really new from here really.. I´ve bought a new EGR, and the SCV and PRV. I have not had the time to do anything about it since last update.
I still drives like shite (and now with a hose/pipe-leak from the turbo)
Acutally it drives quite well @ 100 km/h, but driving a lot around Copenhagen, I spent most of the time under 50

So next week and in the easter holidays I hope to change the things mentioned above. Question: I the MAF and MAP-sensors are bad, will the IDS tell/show it? That´s almost the only things I have not changed. I´ve managed to neogotiate with the breaker, so that I can try the actuator from the 2.2 that he has... if these fixes also have no effect... I´m really not looking forward to the time, where EGR, PRV and SCV is done... and nothing is changed I sure hope it´s not the case.

Well, I have bought this http://xtrons.com/pf70fsfs-b-7-hd-digit ... focus.html - found it second hand, close the motorway where I went with the coffeebars last thursday. I have bought reversing camera too. It acutally works quite well apart from the sat nav. I have tried the screen mirroring, but thats is not something I´m going to use I think. It plays DVD, takes a SD-card with MP3-files and the bluetooth works both with the phonecalls and music. Quite nice and a nice upgrade
Now I have to find a decent sat nav software, that is not pre 1990 It´s and old Win CE version and I have downloaded this version http://www.desnav.com/europe/112-wester ... obile.html but it takes 10 minutes for it to start, and the screen when navigating can´t keep up. It comes with standard with the KUDOS and the download in their page has not been working for a week now..... writing this, I can suddenly download the trial for Western Europe So I´ll see how that plays out.. The original map on the SD-card was corrupt.... and again, it´s just a backup, as the maps are outdated.

Last question! I still suffer from very poor power steering. Driving along I don´t notice it, but a low speeds it really makes some noise as like it´s struggling to turn the wheels... I´ve filled it up with fluid which hasn´t done anything... New power steering pump?

Have a nice day!!

[Kristianskaffe]

New power steering pump?

We´ll see.. just bought a used one

[Airthies]

Crap.. Or what to say..
All 5 wires test OK. Suppose, that's a good sign.
Everything is beeping as it should.. So now I'm in the dark again.

Any good suggestions on what to do now?

Only thing I may suggest is that when testing each wire for beep tone. Shake the bunch of wires going from body to engine to make sure it's not partly broken and made worse with movement?
Also if when testing (depending on your meter) it may give you a reading or change to check for resistance (like that symbol but without bottom line). They should all read roughly same (next to nothing) but if for example maybe the one sending signal to pcm is higher than rest it may cause pcm to think unit is in a position different to where it should be and so the readings pcm is getting are out of it's range so it says it doesn't know where it is?
But if you can get an actuator that would help eliminate any doubt there hopefully before going back into the wiring.

Your doing yourself proud with what your dealing with. Keep at it mate. I'm glad I never gave up on mine when it was causing trouble it's been worth it for us.
