Aye, your MAFM theory may be bourne out yet if it turns out the valve timing is out...

Got some time to look at the camshaft dowel pin issue today, and the reluctor issue on saturday. Both perfectly fine, pin has been replaced but its in no way unservicable.
Nodule on camshaft is also fine.
Have spoken to the original garage regards getting injectors bench tested. They might be able to borrow another santa fe.
Fingers crossed..

Just to follow up,

Car was returned to the original garage, I wanted a proper injector test doing by an injector specialist. All has gone quiet, the last time I spoke to them, the injectors had not yet been tested. Owner was wanting to sell the car.

I also heard second hand that the first time it was rebuilt, the headgasket supplied was incorrect, and starved the head of oil. Apparently an overheat and seizure followed. Another something I wasn't made aware of.

Hello, it´s an old topic, but it can help somebody. I had similar problem (maybe the same) on D4EA engine. It is the same as 2.2CRDi just 2.0CRDi. Realy excessive black smoke from idle, poor power when driving. Previous car owner had done some cylinder head repair. Compared to an another car when idle: Injection amount 11cubic mm istead of 5, exhaust gas temp 290 celsius instead 210, engine load 44 instead 27, lambda 2.5 instead 1.1. The timing side is okay, but scope shows that cam sensor is two teeth offside. Dissasembled and removed the head: the first camshaft bearing siezed and a new valve rocker fitted. I decided that there was a bad damage not repaired properly. Ordered new camshaft and compared to old one: the old one was 10 degrees twisted. Sent the head to specialized company for repair. After repaired head and the new camshaft fitted all values from ECU are good,black smoke disappeared and engine runs well.

Hello,

Did you find out what was wrong?
Is MAFM readin of approx 450ml/stroke in idle OK??
Do you remember value of opening of EGR valve?

BR, Urban

Hi guys, got a problematic hyundai santa fe' in at the moment. Its come from another garage that removed the head to drill out a stud. Once it had been rebuilt it has always had a problem with excessive smoke. The previous garage have been trying to sort it for 2 months, in which time the head was removed again to check for problems, and when non found the head was refitted. EGR valve has also been changed by them.

Engine is 2.2 crdi, D4EB, Euro 4 with DPF, bosch EDC 16 C 39 management.
I've covered alot of stuff already, verified correct reading of MAFM, verified timing correct (cambelt engine), injector leak back comparison. Operation of VGT - not actually seen vanes but the linkage is free, and boost pressure responds to manual adjustment of vacuum.
EGR side of things is fine, good offset between EGR and MAFM, no leaks neither on EGR nor on turbo pipework.

Fuel quantity of 9-11ml at idle with MAFM readin of approx 450ml/stroke. Thought that seemed a little excessive myself?

On a drive its very smokey under accel, with no smoke what so ever on the over-run (confident its excess diesel rather than oil leak into exhaust, smoke is jet black and very sooty).
Aside from the smoke it runs ok up until the DPF gets unhappy. At the moment I'm getting P0473 - Exhaust pressure circuit high input, and P2002 DPF below efficency. My guess is the former is the detection stratergy of the latter. I have tested the differential pressure sensor and it responds fine to syringe pressure, with a tee to pressure gauage - figure on livedata corresponds to pressure provided.
Starting to look at injector timing now, and hence the need for a good waveform - hopefully one showing injector timing too.

Thanks

Fuel quantity 9-11 is really excessive (it was the same in my engine before fixed), there should be about 4-5. My engine smoked realy heavy black. Timing gear side looked good but on scope printscreens there you can see the cam signal is two teeth misaligned. Finally there was twisted camshaft, just about 8 degrees.
