Hi everyone, I've been bringing a 2010 2.0t Passat back from the dead, and the whole thing is just about sorted. There is a nagging issue with a cold start misfire, and I'm hoping that the folks who are more knowledgeable about what to look for, and when, can lend a hand. This is cross posted from the Vortex forum, and here is the original post below:
The issue first presented itself the morning after a longer than usual drive. Upon starting from dead cold, the engine would not stay running on it's own initially, would stutter, and then stall. If I proceeded to open up the throttle a bit, it would run (somewhat unhappily, but it would run). The odd behavior is that it would only do this for a short time, less than a few minutes, and then basically flatten right out into a happy idle. It would not gradually improve, it was as if there was an on/off switch to the issue. One second it would not idle, the next, fine.
Ambient temps in the high 50's Fahrenheit, and the issue seems to cease when the coolant temp reaches 50 Celsius, but I don't know the delay on the sampling.
The issue only happens when the engine is completely cold, and only for those first few minutes. No CEL present.
In my time of ownership, I've done what I can to take care of the usual 2.0tsi issues. Here is what I have done/replaced:
In my time of ownership, as I do with most cars, I've gone through the engine bay for the details;
This morning, the engine idled fine from cold (1200 rpm), but then when settling down to ~700 or so, the engine began logging tons of misfires, with a flashing CEL, but again, as above, after a short time, calmed down and drove as normal during and after several shut downs/restarts.
I'm fairly mechanically inclined, and can typically troubleshoot my own issues. I know that one of the big three (fuel, air, spark) is not happening in the right quantity, or at the right time. Without a more descriptive diagnostic code, I'm a little lost. It nearly seems as if there is a component that doesn't know that it has failed, so the system isn't seeing the trigger for the CEL.
Any inputs on where I should start? I realize I have this incredible tool in VCDS, but at this point, having looked at some of my logs, I very honestly don't know what to be tracking to hunt this down.
Some of the measuring blocks I've been logging (not all inclusive):
Any assistance would be appreciated, I am a VCDS rookie, but love the tool. I also very much enjoy this car and would like to sort it out completely. The diagnostic on this is specifically difficult as it only happens at dead cold, and that is only in the morning while I am trying to get my kiddo to daycare.
I am wondering if there is a block to view if the injectors are drowning the cylinders in fuel due to leakage, but I am not sure how to verify short of replacing the injectors. I am sure there is a better way to measure air/fuel ratio, but again, not sure which block to use. Fuel mileage does not seem to be suffering, 25-29 average depending on amount of highway trips. So leaky injectors seem unlikely.
Present me:
I had a user suggest that the MAF could be the issue, so I did a bit of digging to see how I could best test this with VCDS, and my follow up post was this:
Bringing some data back to this, I logged a cold start this morning coupled with a short drive around the block, and I noticed something interesting with the idle adaptation (or lack there of):
As I understand it, there should be some short term fuel trimming happening in group 32.
You can also see that when the O2 sensor comes online into closed loop, the lambda control is pegged at 25%. Eventually, the mapping calms down:
But something does seem odd with the start up behavior.
I logged a WOT run (short one) to see about MAF behavior, and here is the readout:
Seems like this is within normal spec, but any input is appreciated on that front.
With no adaption happening at idle, it would seem that the MAF could be the culprit, but there is certainly a challenge here with information overload.
Present me again:
Here is the autoscan:
Any help would be greatly appreciated. I believe I understand what the data is telling me, but what I don't really have a great grasp on, is why it is behaving the way it is.
Logically, if I get the gist of what I've read, is that if the lambda control is pegged at 25%, it is essentially telling me that it is seeing the leanest possible condition and doing what it can to compensate to the limit of its threshold (25%). But what I don't think I know what to look at is the corresponding values to see why, or if it is even effectively changing the map.
I do understand that air flow meters, MAF/AFM/etc, have a habit of going bad without them really knowing that they are broken. But they are not inexpensive, and it would be helpful to see if I can trouble shoot a bit further to gain some confidence.
I've also done the O2 sensor test (block 34?) and VCDS calls the sensor OK.
Long first post, but if I've learned anything by lurking on here, y'all would much rather have as much information as possible!
Really appreciate any help!

In my time of ownership, I've done what I can to take care of the usual 2.0tsi issues. Here is what I have done/replaced:
- Carbon cleaning (walnut shells)
- Coils (OEM)
- Plugs (OEM)
- Oil change
- Injector cleaner (not my magic bullet, but I had some laying around)
- MAF cleaned
In my time of ownership, as I do with most cars, I've gone through the engine bay for the details;
- Checked/repaired any vacuum lines
- Replaced air filter
- Checked all host clamps/fitments
- Verified all electrical connections are solid

- Coolant temp
- Ambient temp
- Fuel trim (block 32? I can't recall, but it's a percentage value)

End----------(Elapsed Time: 02:08, VBatt start/end: 14.4V/14.3V)-----------Any help would be greatly appreciated. I believe I understand what the data is telling me, but what I don't really have a great grasp on, is why it is behaving the way it is.
Logically, if I get the gist of what I've read, is that if the lambda control is pegged at 25%, it is essentially telling me that it is seeing the leanest possible condition and doing what it can to compensate to the limit of its threshold (25%). But what I don't think I know what to look at is the corresponding values to see why, or if it is even effectively changing the map.
I do understand that air flow meters, MAF/AFM/etc, have a habit of going bad without them really knowing that they are broken. But they are not inexpensive, and it would be helpful to see if I can trouble shoot a bit further to gain some confidence.
I've also done the O2 sensor test (block 34?) and VCDS calls the sensor OK.
Long first post, but if I've learned anything by lurking on here, y'all would much rather have as much information as possible!
Really appreciate any help!
