Yes, agree with that!

Would you be able to get any more of a definitive answer if it is the crank sensor with the Tech 2 kit (and of course your knowledge of using said software?!)  Is it relatively easy to change the crank sensor?  If I came down armed with a genuine replacement, could we fit it together?

Also, do you know the interval for the cambelt? 1.9 turbo diesel (120Bhp) engine in 2007 car?

Autodata quotes 100,000 mile or 120 months,but Mdtm may know better :y

Thanks!  Therein probably lies my answer, vehicle mileage 98k!!

I ask the question as there are a number of things that can cause cam sensor errors, one of which is a slack belt or a miss timed system.

Its a good bet that as the belt has not been touched that all is ok here.

Correct, water pump to be done at the same time to.

Does this make any difference to your diagnosis then?  Or was it just a question?  Thinking about it, are you thinking the belt may have stretched?  Be on its way out?  Hence putting timing off slightly?

EDIT: sorry must type quicker!!

Update: have the car back at home now, still doesn't start very well at all!

I have done the pedal trick:

ECN245248 means P2452 relating to Particulate Filter Pressure Sensor

ECN34028 means P0340 relating to Camshaft Position Sensor Circuit

ECN38008 means P0380 relating to Glow Device

I think I have the above correct, please let me know if not.

The P2452 doesn't always show, assume that is because the car has not been run for a LONG time, and just idled.

The P0380 maybe means failed glow plug? When you turn the ignition on, the glow plug light stays on for a bit (longer than it used to) and then it flashes. Not going to be helping the none starting I assume.

P0340 I recon is the same fault as it always was, and after Mark Calib DTM's suggestions I think it is the crank sensor as the cam sensor has already been changed.

Any suggestions what to do now? How easy is the crank sensor to change?

Cheers in advance.

Morning,

Yesterday finally got round to changing the crank sensor, done but no better, in fact worse! Car still won't start.  Did notice the crank sensor had oil all over the end, assume that is normal? Have noticed that the glow plug light does not come on at all when ignition turned on. Can just sits there and cranks over happily, no sign of life at all. Any thoughts?

Not sure if these are related but the car also has the following issues:
1 - Deadlocks not working
2 - Heater fan not working at all now, was only working on 4 , now nothing whatsoever.

These problems started after the new fuse box and cam sensor were fitted by the garage.

Look forward to any suggestions as at a complete loss now, thought the crank sensor would solve it.
