Hello everyone.
I had a high idle (ca1300) on my xjs MY95.25. I installed JDS 118.5 (thanks to motorcarman). Unfortunately, after connecting the car and entering VIN, the adaptation option was inactive. When I typed VIN from the same car, but MY96 - I made the adaptations. Idle - great, but after driving about 10 km - Check Engine - error P0411. Do you have any idea?

 

What is the VIN for your car, last six digits?

The code seems to refer to the air pump. Could be coincidental.

 

That seems to relate to the secondary air injection.pump fitted to US cars.

Lots of threads here and in x300 saloon area. Just Google P0411 and you'll find plenty.

Cheers

Paul

 

I know what the code means. Check activated after throttle adaptation. Is it a coincidence? Maybe the adaptation with no my VIN is a problem?
My: 199738
My96: 222758
