Hello, my 2004 x5 3.0d runs lumby on idle (not always). Went to the dealer for reading out. All the 6 injectors runs instable, he told me to replace the 6 injectors after he putted injectorcleaner in my fueltank. I can't believe that the 6 injectors are broken at the same time. What do i have to chek? greetings

I apologize, I didn't realize you have a euro version. What I would do is check tappet lash. On Mercedes, it can cause lack of power, poor fuel economy, and a poor idle. Let me know what you find and I will advise further. I apologize, I didn't realize you have a euro version. What I would do is check tappet lash.

well is it a diesel or petrol?? either way it seems odd that all six injectors have played up at once regardless.i would look at the ECU?? or at least think about it well is it a diesel or petrol?? either way it seems odd that all six injectors have played up at once regardless.i would look at the ECU?? or at least think about it

if this vehicle is built for the europeon market then you cannot read the software ,its encrypted and will not pass the american emmision test as the OBDII cannot be read by the testers ,now as for the fault then all six injectors duff -- i dont think so ,look at them and one of them is the master that leads the others ,iam sure its number 6 but it could be no 5 ,bit out of my league here as i havent worked on one as YET but if i could get my nose under the bonnet i would soon work in out.I think this garage you went too the mechanic is only used to working on oversize gas guzzling CO2 poluting petrol engines and doesnt have any idea on how a proper machine thats built by my teutonic cousins across the non existant border should perform,.Still think the ECU is playing up or a sensor thats controling it ,try the bosch diesel specialist and see what they say ,well you do know what they say about the ideal car ,italian body design,froggy interior design , german engineering and english mechanics then you have a world beater if this vehicle is built for the europeon market then you cannot read the software ,its encrypted and will not pass the american emmision test as the OBDII cannot be read by the testers ,now as for the fault then all six injectors duff -- i dont think so ,look at them and one of them is the master that leads the others ,iam sure its number 6 but it could be no 5 ,bit out of my league here as i havent worked on one as YET but if i could get my nose under the bonnet i would soon work in out.I think this garage you went too the mechanic is only used to working on oversize gas guzzling CO2 poluting petrol engines and doesnt have any idea on how a proper machine thats built by my teutonic cousins across the non existant border should perform,.Still think the ECU is playing up or a sensor thats controling it ,try the bosch diesel specialist and see what they say ,well you do know what they say about the ideal car ,italian body design,froggy interior design , german engineering and english mechanics then you have a world beater
