1.6TDI Engine Misfires and Stalls when Idle

airbus · May 22, 2014

Hi All,

I have a 2010 1.6TDI VW Golf Bluemotion, engine CAYC with 99K miles on the clock. I have had an issue with this car engine recently and hope someone can assist please.
Until today, the car engine (when cold) started and then the idle revs fluctuated occasionally between 800-1200rpm until the engine has warmed up a little (2 minutes or so). Here's what I did today whilst investigating the issue...

All the output tests were completed successfully in 01-Engine module with Passes where appropriate.

I then went into Basic Settings and cycled through the various options and ran them.

Unfortunately by doing this I have made the problem a whole lot worse. The car now starts, shoots up to 1200rpm, down to around 600rpm, up and down and often stalls at idle when cold before attempting a restart. Oh dear.

No fault codes are present before or after my messing.

I am wondering what I have done wrong and if there is any way to back-track on what I did. One of the things I clicked on was 'adapting injector minimum deviation quantity'. This just revved the engine constantly between approx 2000-3200rpm for 10 minutes or so before I gave up on this and went to the next option. Would I mess up settings for injection deviation by doing this? The measuring values show negligible deviations on all 4 cylinders but I am looking for anything right now before I go down the mechanical route

My engine ECU software is up to date at version 9970. I have also checked with the dealer whether there are any outstanding workshop campaigns on my engine part number (03L 906 023 DQ) and VIN including TPI 23F7 and the dealer said that TPI doesn't affect my vehicle. This TPI addresses misfires and juddering at idle and I believe it involves changing the ECU which to me would cost plenty of $$$. Before I become committed to going down this route (and since the dealer says my VIN is not part of the recall), I am trying to figure out if it's something else I have done to make it worse...

Any help would be great. Thanks.

Hi, I will do thanks.

MAF & EGR Specified/Actual consistent, I will check up on fuel temp/coolant sensor. Can simply going into Basic settings mess things up...? I read that Min. Qty adaptation of injection valves (MFMA) must be done after successful adaptation of new ECU software version. Can this be done through VCDS for UDS protocol engines? Thanks.

Jack@European_Parts · May 22, 2014

It should I imagine....did you set the adp for the injector calibrations in new controller?

Couldn't see a setting for that in VCDS? In the meantime, I have been to the dealer and paid for this to be done.

Any noticeable changes since the alleged calibration. I had pinking upon acceleration before, I don't since this calibration was done. Is there any way I can check that the dealer has actually done this through VCDS? I think they have done something because of the less 'pinking'.

Unfortunately, I now get the revs still fluctuating wildly when the revs are set to around 800-900rpm, they then fluctuate between 600 and 1200rpm constantly. It is more pronounced when the engine is cold. Nearly disappears when engine hot with very slight fluctuation.

Coolant temperature whilst at operating spec is between 88-90C. Fuel temperature is 31C and Outside air temperature is 17C.

Any advice would be great, thanks.

airbus · May 25, 2014

OK, a little but significant update. I took a few more logs and was looking some more through them. At above 1400rpm, the Injection amount deviation is 0.0002 mg/stroke on all 4 cylinders. At idle, this is what I am getting...

Would anyone with access be able to find out what is the specification for deviation allowed on the 4 cylinders for my engine code CAYC, part number 03L 906 023 DQ ?

This brings a whole new complexion to the issue, I am guessing there is a fault on injector 3, perhaps it's all coked up? Is there anything I can try in VCDS to help this? I am wondering whether injection calibration has been done correctly by the dealer and whether any software correction can be made by me. If not, then at least I know where this is heading...cylinder 3 injector clean up or replacement.

Thanks.

Jack@European_Parts · May 25, 2014

Each injector has a calibration # on it.
It should still be very close if not exact to what is on the injector in ADP channels to be observed since it was just performed.
I will have a look at an 03L we have here and see if I see anything for deviations after inducing some issues.

Calibration number on each injector matches that for the each cylinder in adaptation. My concern is that there is another calibration done for minimum quantity that I am not familiar with, that the dealer may have completed incorrectly.

If there is no other calibration that can be done other than checking the number on the injector matches that in adaptation, then I think I may have an injector problem.

Any added information would be great... Thanks.

Have you done the block 200 count down test?

0x01-04-200 ON/Go Brake and gas pedal depressed.

Uwe · May 26, 2014

Since the ECU uses the UDS/ODX protocol, as evidenced by:

ASAM Dataset: EV_ECM16TDI02103L906023DQ 003011
ROD: EV_ECM16TDI02103L906023DQ.rod

there are not going to be a Block 200 in the traditional sense. I expect the equivalent in this ECU would be Basic Settings -> Automatic test sequence.

-Uwe-

Jack@European_Parts · May 26, 2014

Does this car have any carbon build up in intake ports?

Yeah slipped by me this was UDS................ automatic test sequence sounds correct to me.......did you do this yet?

You can also swap the injector to see if the deviation moves......its not that hard just need new gaskets afterward for sealing the nozzles and some say new lines but I say baaaa reuse with fine polish and lube for testing.

I did cycle through the various options available to me in Basic Settings, I also did the Automatic Test Sequence again just to be sure and it went through that fine. Under Readiness I see all items passed. I noted that when I had taken it from the dealer after they claimed to have adapted injector minimum deviation quantity, most of the items there were fail. Running the automatic test sequence solved this.

I am trying to figure out whether the dealer did indeed Perform Min. Qty Adaptation (adapting injector minimum deviation quantity), they claimed they did but I am looking to definitely confirm this. If there is a way for me to do it myself with VCDS, even better? All 4 adaptation channels showing 7 digit number on injectors check out, I am unsure whether Min. Qty Adaptation is different to this though, anyone know ??

The article which brought this all about is HERE, not my engine granted, but similar and I have most of those symptoms.

Yes, done twice for good measure along with every other option in that list HERE that the system would take

Good idea, I will probably do this as a last resort.

Action plan I have at the moment in this order.
1. Confirm I know it's not software adaptation (or lack of) causing the problem.
If VCDS can do this on the CR engines, all the better! I tried the option 'Adapting Injection Minimum Deviation Quantity' in Basic Settings, the engine revved up and down constantly (brake pedal and accelerator pressed) for 10 minutes before I gave up on that and went to the dealer...

2. I will move on to diesel purge to see if that releases any sticking injector.

3. Inspecting and getting new injectors as a last resort.

Thank you.

airbus · Jun 2, 2014

OK since no response to my last message I went ahead and did a diesel purge on the injector system, unfortunately it didn't make the cylinder 3 injector any better, still the same deviations, although they look to be more
sporadic in their fluctuations now.

I am going to try it some more but was wondering whether vcds can allow revving of the engine past 2500rpm whilst the car is stationary? I think this may help while feeding the diesel
Purge clean into the system. Thanks.

I would swap the injectors to see if the value moves...........

OK thanks, just trying to gain the courage to do this. Is there anything I should be wary of when removing them apart from making sure I don't strip the threads :rolleyes:

Did you manage to check any of the 03L engines in your workshop to see what values constitute as 'normal' ?

Jack@European_Parts · Jun 2, 2014

Bahhh

You can do it.......its real easy.....valve cover splits...... without the need to remove to access.
Pretty straight forward.

I will have some logs I believe in the morning to compare now that I was able role a Scirocco out of the bay I been working on.

OK that would be great thanks.

Okay this is what I have.....

I believe the spec. should be @ IDLE -2.8 to........ + 2.8 Mg/H Deviation permitted.

Actual logs of deviation in car I have here at Idle.

ZYL #1 + .09 to fluctuating + .12
ZYL #2 - .16 to fluctuating - .14
ZYL #3 - .19 to fluctuating - .16
ZYL #4 + .24 to fluctuating + .16

It seems to me that looking at cars with no errors.
There seems to be a common of positive or negative deviation based on 1 & 4 being shared like 2 & 3 being shared stroke placements of piston.
They can be inverse but it is something to note since 1&4 are at TDC while 2&3 would be at BDC.....

So yeah......... I would swap an injector to see if it moves, because even though it is within spec it is far from in correlation with others.

That correlation is not being shared in yours though.......so I might try to split the positive ones with 1 & 4 and negative with 2 & 3 just to see if it changes the balance of seat of the pants operation.

Jack, thanks for this info. Yes strange how spec has such a wide tolerance, perhaps that's why it isn't throwing a fault code on the ECU.

I think the swapping of the injectors is the only way to go now. Do you have much problems with seized injectors on the CR engines? I have done some research and it seems the injectors or not actually screwed into the head, instead held on on pairs via a clamp. Is a special pulling device needed to lift them out of the cylinder or is it simply a case of wiggling and pulling providing they're not seized?

Thanks.

Jack@European_Parts · Jun 3, 2014

Correct sir.........no DTC because within the threshold of operation.

I use the factory pulling tool, which attaches to the threads of the injector......... as per the repair manual.

Yeah they seem to come right out in my experience......... so far pretty easy compared to the VE ALH which get corroded.

Good luck.....
