Power Loss AUY 85 kW: Causes & Solutions

Hi,


I'm having a problem with my AUY. It's been giving me trouble with intermittent performance issues. It sometimes runs well, but then it doesn't work shortly after. The maximum speed is usually reached, but sometimes it's hesitant, and sometimes it's faster.
The LMM (mass airflow sensor) was replaced at approximately 25,000 km. During the 35,000 km service, the air filter, diesel filter, turbocharger boost valve, and a vacuum hose were replaced.
The loader is making scraping noises during load changes, specifically in the range of approximately 1500 RPM.
Currently, it vibrates when it makes that noise (difficult to describe). Measuring it is easy. Seat apparently has a modification available to fix this issue. Unfortunately, Ford does not.

'Things have been pretty slow since yesterday. Top speed, even with a good run-up, is only 170. And not much more going downhill either.'
Logged in today. My suspicion is the mass airflow sensor (MAF), but I can't quite believe it, as it's only done about 15,000 km.
Please take a look at the logs.

It is a Galaxy, PD 85 kW, AUY 10/01.

Before I buy an LMM.
Or it could possibly be something else.

Thank you very much.

Hi, if there's a conversion kit available for that, why don't you go check with Seat?
They can probably help you.
