Hello everyone New member with a seemingly unsolvable problem...
Just recently decided to buy a used Audi A4 2.7 tdi 6 speed manual ( year 2006) with a problem... was a dirt cheap car due to this issue. Seller said "Slight shake at idle and gray smoke the first couple minutes after start". Suspected it will be an injector issue and went to look at the car armed with VCDS. Did a scan and checked the Injector Quantity Deviation values and sure enough Cylinder 2 and 4 were totally out of spec. Bought the car, took it home on a hour long drive. While driving the car would noticeably shake with acceleration under 1500 rpm higher rpm and its fine... was sure its going to be injector swap. Ordered 2 second hand injectors of ebay and installed them to replace Injectors 2 and 4. Coded the new injectors to the ecu all fine. But no change with the issue whatsoever! Injector 2 did actually improve but inj. 4 stayed the same maxed out.
So far I've narrowed it down to cylinder/injector 4, It's always sitting at + 4.99 - 5.09 mlg/str. but here's the problem, even if I take a known good injector from cylinder 2 and swap it out. It's still giving me the same result. Also, while the engine is running, when I unplug any of the injectors it increases the lumpy running, Except injector 4! (Also unplugging other injectors mimics the behavior of injector 4 - sitting at 4.99 mlg/str. and slightly drops when increase in rpm.... though I'm confused how do I still get a reading if the injector is disconnected from the loom??). At first I thought the wiring to the injector is bad. Tested for continuity across, no shorts. tested when running and it's getting the same voltage signal as the rest at 0.07-0.14 volts. And another odd thing which I don't understand is the Cyl. Activation Calibr. Pressure on cylinder 6 being all three numbers 6.0-2.0-6.0 ms and cyl.3 at 0.0-0.0-2.0 ms, what does it mean? So I'm well lost what's going on with this car. Want to save it, nice red Sline.
Any ideas ?
Also have a fault code for all 6 glow plugs, but the car starts with no problem every time even at -3c
And a fault code on Intake Manifold Runner Bank 2but that wouldn't result in such a terrible engine running?
