Poor performance between 1000 and 2000 RPM, 2.5 TDI, 85 kW

hey guys...
Regarding the starting problem, I've also noticed that the performance between 1000 and 2000 RPM isn't great. My girlfriend has a 90 hp 1.9 TDI, and it seems to perform better in that RPM range.
Could this be related to my starting problems, or something? Or is it normal for the 2.5 TDI engine to feel sluggish in the RPM range?

I've now replaced the diesel filter, air filter, and the return lines on the diesel filter, but I still haven't had any success with the starting problem.


Best regards,
saxi.

Hello,

Have you ever recorded/had recorded the measurement data?
We might reach a conclusion faster this way.

hello!

Actually, no... he only connected the engine tester without starting the engine. Is it normal for the tester to be connected only without starting the engine, or can we only say for sure once the engine is running?

Hi,

My parents drive an Audi 100 Avant 2.5 TDI.
He has a significant performance drop below 1800 RPM.
Until then, the AFN is definitely stronger (M-curves) - but then things really take off.
For comparison: the same highway on-ramp with both cars, a slight incline - my Passat (35i) is in 5th gear when going from 50 to 80. The Gang is faster than the Audi, even though the Audi weighs about 13% less.

Conclusion - if you want the AAT to be fast, you should always keep the engine speed between 2000 and 4000 RPM.

Regards,
Munch.

PS - the sound quality above 3500 Hz in the Audi is quite something.

Hello,

In order to access the error memory, the engine does not need to be running.
Unfortunately, we can only get a clearer picture of the problem by examining the measurement data. Certain conditions must be met for this to work (see also the error database).

Hi!

It's pretty obvious that the AAT isn't really going to stay below 2000.
It's not a VTG item!
Since this is still the old turbo, you just have to live with these holes...
Same here...

Hello Michael,


Do you also have the target data for the AAT measurement blocks in the error database, just like you do for other types?

Hello,

I am currently in the process of gathering information for the AAT and ARL.
Please be patient.
