I cna find no reference to Code 11..... it may be a Omnitech only code with no reference to a LR specific code.

I would suggest starting at the beginning and making sure the compressor is making good pressure....follow Wammers guide in the technical archive and go from there.
 
just thought , yeh i know, lol

would the codes change if it’s pre or post being obd2 compliant
 
No P38 was OBDII for anything other than the Petrol engine ECU - all other ECUs and the Diesels Bosch Engine ECU are proprietary only and no OBDII codes were standardised for their use., hence why we always advocate the use of a LR specific code reader or diagnostics device for code reading - else the results you get could be spurious and tail-chasing.

I have heard of Code 11 referred to, but I'll be damned if I know what it means....this is not the first time it has come up I am sure of it....but damned if I can find anything about it!
 
Pressure constantly high or low is usually a problem with the driver pack feeding back into the ECU
 
He maybe better getting some proper dedicated diag on it before jumping to conclusions.

u saying that i was also wondering , shouldn’t there be a letter in front of the codes

ie ,

B- body codes
C- chassis codes
P- power codes (engine)

or do non compliant obd2 generic readers show different codes according to the make etc plse

where as i assume the compliant obd2 readers have the same group codes

thks and yeh i know , i need to get out more ;)

Other than on the petrol engines where OBDII codes apply. Nothing else on a P38 is OBDII compliant and needs dedicated diagnostics to read and work with. I know more than most about EAS and i have never heard of code 11. It may just mean that the diag used could not access the ECU.

I thought I had read that somewhere on this thread before - oh wait a minute I did in an earlier post :D:D:D:D:D:D:D:D:D:D:p

i think i may get something thrown at me for asking a really daft question ;):D

if this is the correct EAS module could a failure at number 11 cause the issues reported by the op

or a case of waiting to hear back from the op for further details
