actual data from today: Air mass should be: 290. Air mass: 436

. There's definitely something wrong here, in my opinion. Otherwise, please post logs from actual operation, see the technical article on troubleshooting performance issues.

Hello Chris, However, there is the following problem: - The car is still under warranty. - The workshop only works on vehicles if Ford pays for it. - It's also not possible to do it yourself, as it's a leased car. Dieter

I understand. Unfortunately, Ford workshops with exceptional expertise regarding VW PD TDI engines are probably as rare as finding rough diamonds on the Baltic Sea coast.
Even at companies like VW or Audi, you won't necessarily find what you're looking for right away, otherwise there wouldn't be so much activity here.

Good luck.
Christian.

Yes

Dieter.

Could you please set up a self-diagnosis protocol, or at least retrieve data from the engine control unit (ECU)?

For the Sharan (which has the same construction), there are software updates available for the control unit 038 906 019 BH with data version 1587 + 1591.
An update regarding incorrect control/processing of the AGR (Abgasrückführung - Exhaust Gas Recirculation).

The new data value is 5630!

It might be a good idea to check that out.

Since you apparently have VAGCOM, it should be easy for you to check that.

Okay, let's start with the performance figures:
Block 0.
Field.
1 150 DZ
2 88 ES start
3 255 Pedal
4 180 ES Quantity
5 220 Intake manifold pressure
6 197 atm. Print.
7 68 Coolant temperature
8 170 Intake air temperature
text
9 142 Fuel temperature
10 255 intake LM

Block 4
2 14.0-16.4 Funding eligibility should be...
3 19.9 Duration of funding
4 1.1 Synchronization Angle

Block 88
2 68.5 Desired quantity (ES)
3 48-50 Torque limitation
4 50.5 Smoke barrier

Block 10
1. 945-1025 LM is...
3 2170-2340 Intake manifold pressure
4 100 Pedal

Block 11
2 2346 Charging pressure should...
3 2316 The boost pressure is...
4 56.2 Key press ratio


Self-diagnosis protocol - I'll see if I can find that, as I'm not quite familiar with it yet.

Let's start with the performance specifications.

We can't really do much with these snapshots.

"First, create a continuous log using sensors MWB 8 and 10 during a full-throttle acceleration in 3rd or 4th gear, from approximately 1500 to 4300 rpm, and then we can analyze the data further."

If you go into VAGCOM and then select '01 - Engine,' the identifier of the engine control unit (ECU) will appear at the top of the screen. It's very easy to read and write.

Sure, I will translate the text from German to English. Please provide the text you would like me to translate.

the top two fields...

In this case, the part number is 06A 906 032 E, and the data version is 2730.

The performance curve looks a bit strange, but Bosch's diagnostic power measurement systems without a brake are also only suitable to a limited extent for diagnostic measurements.
The power loss is perfectly normal (the 8 kW mentioned by Rainer is already included). On our dynamometer, cars like this typically have a power loss of 17-20%.

Hello,
In Ulf's article about the dynamometer calculation tool, I found this link regarding the (un)reliability of dynamometers and the diagrams generated by them.
http://www.hs-elektronik.com/leistungspruefstand.html
It's possible to manipulate a measurement within certain limits using various correction factors and similar methods, ultimately producing the result that the customer or client wants to see. Perhaps this argument can be used to question the diagram and encourage the workshop to think further about the issue.
Did the workshop itself commission the test? During such a phone call, you can also conveniently "order" the desired engine performance.

Regards,
Karsten.

I think we should stick to the problem at hand, regardless of the diagrams. What we need are measurement data. Without them, we can't make any progress, and it will all remain speculation.

Just checking in to see if there's been any progress on this.
