hi all, right my a4 has a bkd engine fitted. it did have BLB but i assume it got nuked like most of them do.
I thought id post about the bkd in the a3 section as its not in the a4s. by code anyway.
i have cold start issues, it will wind and wind and then splutter into life and run for 15 seconds fine. then will misfire and chuck white smoke out as in plumes, but if you take it for a drive it clears and only pops the odd puff.
it drives fine under load with no major issues but if you try to drive constant it lurches, not bad bad but bad enough to make any passengers think you cant drive.............
when warm it starts fine, still smokes and misfires.
its had a head so its not the coolant issue
its had a head loom
its had all 4 injectors recon'd
egr valve cleaned
tandem pump gasket - someone had used the old gasket when doing the head and had also used that gasket sealer which had gone into the diesel and oil ways but iv sorted all of that now.
turbo seems fine, no play in shaft etc
now what? injector readouts when warm where 0.71 0.31 1.32 -2.38. i then had them recond and they are fine!
im sending the ecu off to be checked tomorrow.
but could i be right in thinking that if the tandem pump gasket was the issue and the oil has mixed with the diesel and the car now has less than a quarter tank in that the fuel could be contaminated? just a thought?
any help will be very much appreciated.
