Hi Dave,

I did not do anything about the problem when you first replied, as it always started the second crank.

But it is now worse so I think I had better sort it out.

I did come across a good explanation, I will attach the file.

Many thanks for all your advice.

Best wishes
Peter

Hi Peter,

My 2005 Ducato has also developed this fault of late. 'Your' explanation is an excellent one given that it is thoroughly researched, evidence based and provides a ready solution. Slightly puzzled as to why it has taken 5 years to manifest the glitch though.

Thanks,

Kevin

Hi guys I have had this issue with my camper. I found on auto data there is a service bulletin for this issue. I have made a video on YouTube to show fix.

Link is safe, such a simple fix if correct, just added washers to raise the pulley sensor. Only took 10 years to respond to thread.

Why do we actually need a crank sensor? RPM.?

Probably linked to a plethora of diagnostic elements for the ECU.

You got me thinking Ray.......Got this from Google

A crank sensor is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters.

Thanks Terry. But it still seems an unnecessary complication to me. Like immobilisers that fail just when you need to go somewhere urgently.
