    w245 CDI euro5 won't start

    rail pressure in not triggering fault code during a start, but it might give a hint there is something fishy in pressure... fuel quantity valve is most common, unless it is injector excessive leak.

    C229 Fault Code

    whats description of the code? Any symptoms?

    Injector figures

    Do a leak test, number 4 shows bad on idle. It means it has to increase opening time (usually due to leak) to keep running smooth, Of course you can try calibration like xentry suggest. Negative values are compensating that one which needs more fueling. I would change only #4 at first, then...

    Fuel temp sensor

    maybe, if it shows too low temp... in may even prevent engine to tart is showing too high value. Of course temp is ambient temp when start engine, some higher when running.

    Hi from Sweden!

    I have imported my W212 and C219 both from Sweden :) I think Swedish started to get rid of big diesels about 5 years ago, so got them much cheaper than in Finland, of course currency exchange rate played a some small role too.

    651 C220 cdi Pressure regulating valve

    SDS is giving values usually by PWM %... Your battery voltage is also very low...

    HOLD inoperative - See Owner's Manual

    that was fastest discovery - discard I have seen :) Like above, it is usually problem in gear selector.

    651 C220 cdi Pressure regulating valve

    well you has no pressure on rail and no sync on cam/crank sensor... both preventing engine to start... BUT, when that fault code triggered? Before even attempt to start?

    651 C220 cdi Pressure regulating valve

    injector stuck open?

    Anyone northeast with STAR or similar - MAF Adaptation

    SDS can cross test MAFs, I think too one or both MAFS are bad.

    Anyone northeast with STAR or similar - MAF Adaptation

    ALL. Ignition on but engine not running.

    W211 om629 reliability

    I think you should swap propulsion too, parts are probably different in car with V8 than I4. EPC will tell for sure. Brakes are bigger etc.

    W211 om629 reliability

    cylinder liner is a design fault, I can't remember did they fix it at some point. But like said it is not happening on every unit or even very often.

    Anyone northeast with STAR or similar - MAF Adaptation

    Its enough you have some implausibility between your pressure sensors and MAF. Are all pressure sensors reading same at ATM? Intake manifold flaps working? EGR clean?

    W211 om629 reliability

    Cylinder liners are drifting, oil leaks between transmission and engine block, exhaust manifold cracking. Not very often though.

    2005 ML 270cdi cut out and warm start issue

    Engine will be shut down if crank sensor data is not received. So yes. I would believe EPC needs rpm info too. Usually sensor problems start when warm, escalating to cold. But fault codes will tell for 100%.

    Abs sensor or ring ?

    of course they have a ring, laminated to rubber ring. 90% its ring fault, not sensor. Also bearing gap may cause misreadings.

    320cdi om642 bad cold start

    Ok... so basics; your fuel system is not getting enough fuel pressure at start, because primer pump is not able to deliver enough flow to hp pump. This leads to situation where you need to crank longer time, to get enough pressure to rail, because ECU does not allow injection until certain...
