Hi guys, i'm struggling with this car ... somehow ecu requests around 450bar rail pressure at idle and car injects around 26 mg fuel ... what can cause such problems

Is the car stock? or someone has played with it?

Is it idling smooth or is the idle jerky?

Did you check if the DPF is clogged? Check the differential pressure of the DPF filter. Should be 5-10mbar in idle.

dpf is removed ... car ran fine for a year or more according to owner and just started smoking few days ago
from cold engine starts fine - no jerking, no visual problems, just LOTS of smoke and when getting warm starts jerking and eventually cuts off from too much fuel
here is file ...

egr checked ... rail pressure regulator checked ... injectors tested ... and no errors on diagnostics

i know file is not good ... car came this way and customer said car ran fine for more than a year ... now for some reason car requests over 400 bar rail pressure and injects around 26mg at idle
MAF also checked and it is OK .. tried original soft - dpf error is on but car behaves the same way

black is fuel to much....regeneration is holded by dpf off
you have one file with dpf ok,and one with off...first use the normall dpf

Your work is very bad ..
egr off, no ok
fap off, no ok " filter clogging original no 0%"
tuned, no ok "many errors"
I recommend reviewing all the work this is very simple and very good results if you know work

FIRST OF ALL...,IF THE REMAP THAT IS INTO ECU IS A BAD REMAP,IS NO SENSE TO TRY OTHER THINGS LIKE THAT YOU SUGGESTED....FIRST,IT NEED AN ORI FILE ,OR A GOOD REMAP WITH EGR AND FAP-DPF OFF......there are two sollutions mod files posted....regards

i just return from work .... betrescudan i tested your files out of courtesy and guess what ... the same story but i said it many times i already figured that this is not problem with software and plz stop with the annoying comments
tiuken thanks for pic ... this one requests 460 bar at idle and injects 26-30mg of fuel .... and can't see the buildings across from the smoke :)
betrescudan i REALLY THANK YOU for your help :)

hi friend,
first of all make a full live scan for strange "numbers"
from what i have read as now i suppose some possible "fake" info from engine to ecu,
too much smoke at idle some times is not much more fuel but can be from less Air :trytofly:
as betrescudan (http://www.digital-kaos.co.uk/forums/members/342950-betrescudan/) say,,
bad mod file can work for a long time but now you have too much stuck inlet system.
post here some hopeful live scan and i'm sure some of us we can help you :shakehands:
at idle ,live scan Maf quantity-Different Pressure-Injectors quantity..
all this try to scan again with 2000rpm ;-)

car run well on the road or have poor power?

this is the last....i promisse....controll your turbo...and your intercooler..and change MAF sensor...you have not air here...the pressure on your mod file was too high for turbo.can be detroyed....GOOD BYE

i had similar problems with opel mjd in the past,
(fake numbers from brand new gas temp sensor).
i wonder if all troubles was come from bad hardware.
