I’ve posted this question before but I could use some more help in figuring it out. After traveling a good distance at freeway speeds, meaning 75 mph, my Jetta runs fine until I reduce cruse speed to 65 mph. While traveling on a section of hiway described as rolling hills, the car has a hesitation or misfire while transitioning from downhill to uphill. The hesitation doesn’t happen all the time but, when it does it is brought on by the same conditions.

I’ve posted my most recent Auto Scan for those interested.

I’m planning a trip over the same route that this event happens in a couple of days. I’m wondering if I were to sit in the passenger seat with my laptop connected to the car and running the VCDS could I catch a real time recording of events as they happen? If so, how can I do this? What measuring blocks should I watch? Is there a tutorial showing me how to do this?

I know, a lot of questions but, I am so impressed with how this vehicle runs it seems such and uncomfortable mystery having this misfire or stumble to happen for no apparent reason.

Thank You for any help.
Steve

Given that this is a fairly old-school diesel that doesn't appear to have any measuring values for misfire recognition, I'm not sure what to suggest looking at. I guess I'd start with MVB 011 to see if perhaps actual charge pressure isn't keeping up with specified charge pressure during the transition from downhill to uphill, which might be indicative of a slightly sticky turbo actuator, but that's really just a WAG on my part.

At 200k on ODO, you may have common problem that exhaust side on turbo is closed to much .
Now question, when you start from dead end and give full throttle does the car bug down till 2000 rmp and at 2100 pulls like rocket?

Also you can test this on Besaic settings group 011, When you do this between low and high numbers you should not have difference more then 150, ideal is 90-120.

From a dead start and full throttle the car will try and put you in the back seat. No hesitation, just haul a**! :eek:

I will try and make a Log tomorrow on our way back from Tucson. Which is when it happens, after a long day’s running. I will collect a CSV file to cover 011 but I’m thinking of including 007 and 013. I did a test this morning and noticed that the number one cylinder showed a negative Injection Quantity Deviation as a minus (-) number where the other cylinders showed positive numbers. I have no idea if this means anything but I’ll map it in the Log.

I think that the 007 block will show fuel temperature and cooling status. At one time someone had asked me to consider the fuel temperature because of my living in southeast Arizona, aka, HOT!

Anyway, the VCDS has room for 3 blocks at one time so I figured, why not?

Thank you for your help.

Steve.

I made the test run from Tucson to home. I made a CSV log of the event recording measuring blocks 011, 007 and 013. If I can get the log to load to the message board you will see a lot of stop and resumes to the log. I used the “Marker” feature to be able to add some notes.

The first set of data shown as: (some of the Markers were not noteworthy).

Marker 0, (no mark number) is a baseline. It was recorded while heading eastward on I10 thru Willcox, Arizona with the cruise control set to 75mph. This area is mostly flat with no noticeable inclines.

Marker 1: is the first downhill and incline after entering Hiway 191 headed north towards Safford, Arizona. The cruise control is set at 65mph and the roadway is made up of rolling hills.

Marker 3: there is a slight hesitation.

Marker 5: had a noticeable hesitation.

Marker 7 & 15: had a strong hesitation.

I couldn’t get the report to load using the Code tags. The system must think it’s too large. Maybe someone can tell me how to share it?

Things that I noted from the test:

All 4 of the fuel injectors showed within limits readings.

The IAT was 38.7°C (101.7°F) This was about right because the instrument cluster showed 97°F.

The Coolant Temperature was within spec’s. 87.3°C (189°F)

What got my attention was this:

The Fuel Temperature which was 86.4°C (187.5°F) BUT, from what I can see the spec’s say that the Fuel Temperature should be about Ambient Air Temperature.

Also, the Fuel Cooling Status never changed from 0.0% (meaning OFF).

So, if any of the above means anything, what is too hot for fuel temperature and when should the fuel cooling come ON? If I’m right, what is wrong and how do I fix it?

I am planning another trip to Tucson again this Thursday. If there are other blocks you folks think should be looked at please let me know.

Sorry for the long post but, I really do thank your indulgence.

Steve.

Pump Douche engines need lots of flow through the fuel filter, replace it before wasting time with data unless you are an engineer.

Also easy to pull the valve cover and check the camshaft and followers for wear.

You can use the BEW camshaft and lifters, they use less of an aggressive profile and will last much longer than the BRM grind.

The fuel filter was changed about 1,500 miles ago.

I bought the vehicle in 2019, about 10,000 miles ago. One of the first things I did was to inspect the cam, lifters and timing belt. I’m only a licensed airframe and power plant mechanic but to me everything looked very good. The lifters were still all black, the cam and followers showed little wear. The timing belt looked good and was very close to correct adjustment.

That is a great piece of information about the BEW cam and lifters. I will keep that in mind. Thank you.

At this point I’m still wondering about the fuel temperature. Should it be as hot as the coolant? And if so, how hot is too hot and when does the cooling system kick in? OR, turn on as indicated by the 0.0% vs. 100% indication. I know there is a fuel cooler under the body pan on the passenger side of the car. I can’t find any information as to its plumbing and if it has some sort of control for how much fuel gets run thru it.

Maybe I’m just being anal but, the last thing I want is to break down half way between Gila Bend and Yuma, Arizona in the summer. :facepalm:

Again, Thank You for the information. Steve

If they weren't expecting the fuel to warm up, why would they have a fuel temperature sensor? I'm not that familiar with your particular engine, but I'd expect a lot more fuel to come into the engine bay than is needed, and what isn't needed to be circulated out again. But by all means, check the fuel temperature when the engine is cold (right after sitting overnight); at that point, yes, it should read close to ambient.

Not really do you know where is your injectors and where fuel goes in , inside cylinder head?
Like was suggested chnage Fuel filter and see what happens. Fuel filter needs to be chnage every 15000 on those cars after Diesel got chnage to low sulfur.

I changed the fuel filter about 2,000 miles ago for this reason. Noticed no change. BUT, do have a question. My 2006 has the “early” model fuel filter. What was the issue that made VW change the fuel filter design in the middle of the year model? Unlike my Dodge Diesel, there is no physical water drain system in the filter. Just wondering.

You did check to see that the in tank fuel pump is pushing fuel to the filter? I've seen plenty that failed yet the engine still ran until the next guy changed the fuel filter and couldn't prime it.

Interesting and I will check it.

When I first got the car I did a complete service. Engine oil & filter, fuel filter and DSG service including a new DMF (that was a fun project). I’ve changed the fuel filter twice in the past year, about 5,000 miles, thinking that maybe there was something in the system messing with the filter. But, each time I change the filter and inspect it I find nothing but diesel. However, I’ve had this problem ever since I bought the vehicle. I can drive across an Arizona desert freeway at 75mph all day long. Uphill, downhill with never a miss. But, when I reduce cruse to 65mph and drive over rolling hills, it will sometimes stumble when it first tries to increase power for the next incline. Not enough to make you want to pull over to the side of the road but, it does wake you UP!

It won’t stumble at 75mph or 55mph just, 65mph. And, like I noted before, from a standing start it wants to put you in the back seat. At idle it’s so smooth you can put a glass of water on the valve cover.

Mostly it’s annoying. Every time it happens I hear from the passenger seat (the wife) “Whys it doing that”? :facepalm:
I'll keep picking at it.
Thanks for the help.

Also you can test this on Basic settings group 011, When you do this between low and high numbers you should not have difference more then 150, ideal is 90-120.
Did you ever did this ????
Basic Setting 011

Yes I did.

During normal cruse the 011 boost pressures were:
Specified: 1601.4, Actual: 1652.4, % Boost: 71.8%

At the time of one of the hesitations the 011 boost pressures were:
Specified: 1703.4, Actual: 1448.4, % Boost: 73.4%
Specified: 1734, Actual: 1275, % Boost: 66.7%.
The engine RPM was 2205 and the two above readings were less than 1 second from each other (if that’s how the “Time Stamp” works).

Other than when the hesitations happened the boost numbers fell within the 90-120 you mentioned.

Not when you driving, You need to do this at Idle not moving.
You go to Basic Settings , Goop 011 and hit GO, then Record it , and see difference between lower and higher numbers , It can not be more then 150 , ideal is 90-120.
BRM is know for Back Pressure problem. If you have fuel problem , you would have more problems at 75mph then at 65 mph. But if you have back pressure turbo problem then at 65 you will have problem because it is lower boost then at 75 and trying to get up and go with more boost.

Did that too as a base line. Here is what I recorded the day before when I was trying to figure out how to do it.

At idle, 840 rpm, Specified pressure was: 1009.8, Actual pressure was: 887.4 at 82.9% boost.

At 1050 rpm, Specified pressure was 1009.8, Actual pressure was: 897.6 at 82.5% boost.

My oldest son mentioned that it might be a fuel problem from foaming in the tank. If there is bio-diesel, which some of the stations around here mix with their no. 2 diesel, it could foam. Because this problem mostly happens on the way home after being driven all day, he suggested I stop at a fuel station and top the tank off before I get to the area where we have the issue. I usually have a little more than ½ a tank when returning from Tucson. I’m going back to Tucson this coming Monday and will give that a try. It’s just a theory, like you said, such a problem should happen at other rpm's, but I’ll see what happens.

You mentioned a back pressure problem. Could that be caused by a dirty intake manifold? Meaning, oily soot build up in the manifold behind the shutter valve?

The numbers above are not good,at 1050 rpm you should have much more and prcent need to chnage . I will do later my car and post results .
Maybe you have turbo Actuator going bad. Can you check with Vacuum pump is your VNT Actuator working ?

After I look at my car I do not think you did this correct , look at pictures , like I mention above you need to do this on Idle in BASIC SETTINGS , not MBV, Difference at my car is 112.
You will need to turn On Basic Setting on top, they will be OFF.

OK, did like you said (I think I did it right?) and used Basic Settings group 011. I took pictures and copied a CSV log.

Here are the basics of what I saw without trying to upload the log.
Code:
RPM:        Charge Pressure     Boost Pressure        Charge Pressure Control
             Control Status        (Actual)                Duty Cycle. %

1407            OFF                856.8                   9.9%
1407            ON                969.0                  90.3%

This is what it looks like throughout the log. When the Status was OFF the pressures mostly stayed at 856.8. When the Status was ON the pressures varied a bit. 887.4 to 969.0. But the Charge Pressure Control Duty Cycle % stayed the same. 90.3% (I don't know if it matters but I live at 3,200 feet above MSL).

Are these the numbers you are looking for?
Again, Thanks for your help.

Yes , that what I was looking for .
Difference number looks good but your numbers are very low on boost pressure , never seen this much low , Possible someone was messing with VNT Actuator or closing point of turbo exhaust side and that could make problem what you experiencing .
Numbers needs to be close what I have in my post .
Do you have Vacuum pump ?
If you do , can you please do this , Put Vacuum pump on VNT Turbo Actuator, apply vacuum very slowly and tell me when rod start moving what number you have on gauge and when stop?
They need to be when start moving 4-5 when stop 17-19. This can be difficult to see it at first time so may do it few times , you need to catch it soon as that rod move .
