Audi 2.0 A4 tdi brd engine code ,,, injectors blocked????

[Steve autotorq]

Hi new here guys after some technical help please. Audi a4 2.0 tdi 2007 brd engine code. Runs ticks over perfect. But wouldn't pull skin off rice pudding. Vcds engine fault 1 code just exhaust temp probe in turbo. This obviously doesn't give lack of power. Has anyone had similar fault. Is it fuel related as turbo , egr, mass air etc etc all working fine with vcds values. Measuring blocks on injectors does show odd readings but not sure what they should be. The only way it can get driven with some normality is if map sensor is unplugged but then I believe it just runs in basic settings. Any input would be greatly recieved. Are injectors blocked or fuel pressure an issue??? Thanks in advance

Not 1 reply ,,,, cool

thanks for reply tame technician i was hoping u would after reading some of your other threads u seem a good guy.

items replaced so far
new ecu and latest software
egr valve
mass air meter
map sensor
dpf has been raped (ie cut open and emptied) b4 i got involved ( i also believe a bad remap was the cause of ecu dying)
new turbo charger
all pipe work correct
swirl flap acctuator diapragm replaced
apparently according to audi mofified injectors replaced on 2012 recall
electric pump in tank replaced
new fuel filter / air filter
the only code im getting now electrically is the exhaut temp sensor (g235) the one in the turbo charger short circuit. Ive ordered from audi today £113.00 ish
The only other thing i havent checked is tandem pump for pressure can this be checked with vcds i dont think so , unless u know different i think a bar gauge needs to be plumbed to it about 7bar i think it should run at.
The strange thing is i left it parked outside workshop all day yesterday as i was busy. without working on it as i started it to drive inside for overnight safety it revved crisp as the day it was from the showroom, i took it up road and it drove perfect with all power and boost. then 5 minutes later back to how it has been lack of throttle response and no power.
wierd eh??
Any input greatly recieved , Kind Regards steve

Hi chap thanks for reply as u say alot of work has gone into this audi. I have rectified the ecu issue as b4 vcds code was p00000 corrupt software. At least now I have a working ecu. Before u could unplug any sensor on car and still showed no dtc codes. Im fitting the temp sensor in the turbo tomorrow and hopefully then will have a clear code free ecu. The thing that really puzzles me is the fact yesterday eve it ran perfect for 5 mins and again today. But then goes back gutless. The onky other code stored when it ran fine was a dpf fault because as u rightly say tge dpf is missing so once I get it running a1 I need to get the dpf element remapped out the ecu. Could I email u regarding this also.

Another though would it be possible for an electrical component ie mass or boost pressure solenoid to fail but not record a dtc ,, just thinking out the box as I am running out of ideas slowly. Kind regards Steve

Oh well thanks for trying
