I just read the codes earlier on today for the very first time since owning this car. It has, btw, some 530 000km (330k miles).

I got the following codes, but I'm missing some details for a few:

In the order they appeared:

15
8 B11/4 Coolant sensor
9 B2/1a Intake air temp.
2 L7 Fuel rack sensor
3 B2/1 Air flow sensor
11
5

Could anyone help with 15, 11 and 5? I read 11 will always be there... right?

I do experience erratic turbo response and power loss, but I haven't hooked a boost gage yet, so I'll do my work and come back.

I still need to look at the basic timing as well and see if I have a stretched beyond limit timing chain (> 4 deg from what I've read).

I seem to be getting time from 0-62mph in the order of 16-17s when speed is read from speedometer. Fuel tank almost empty and rear seat removed.

I will install my veggie kit on this car after I have gotten it to work perfectly on diesel.

Thanks
