Hi All,

Started to experience an intermittent starting problem. Once in every 4 or 5 starts the engine just endless turns over without starting. It turns over normal speed and sounds fine in this respect. Sometimes the car starts to shudder or vibrate as if the engine is so very close to starting but doesnít make it. Other times it will start in a second no issues.

It runs fine once started.
Plenty of fuel.
New battery and alternator less than a year ago.
No warning lights.
Temperature makes no difference (itís above freezing here at the moment anyway) this morning I got to work, went out 20 minutes later so the car was still warm and it just turned over. I turned the ignition off/on a few times and after a few attempts and it kicked into life.

Iím at a bit of a loss! Any ideas?

Could it be fuel related such as starvation or faulty pump

I'm guessing the answer to this is no (given it's a 2008 vehicle) but do you have a spare key equipped with transponder chip, that you could try?

The answer is may be, sort of. The key chip remains inert until excited by the 'aerial coil' around the ignition lock.

That coil can go open CCT intermittently. Usually, display light with key symbol will flash and then go out. Means that the immobiliser  is still active and engine will not start.

The coil replacement is DIY do able.

I assume @Olympicon  that you have had advice on glow plug function and replacement.

Given that you say car runs fine doubt that it is fuel related although give the primer above the filter a pump just to check that the line from tank and tank strainer are ok

Hadnít thought of the immobiliser although again no lights out of the ordinary on the dash?

I did think glow plugs but the temperature of the engine seems to make no difference, it was 10 degrees earlier car started fine drive to work came out 20 minutes later wouldnít start for a while.
Also no glow plug related warning lights.
Iím not an expert on Diesel engines, on these do the glow plugs only kick in when cold or are they required for every start?

Fuel wise, by now Iíd have experienced running issues surely considering how often itís struggling to start now

There isnt one. Just the cct check light when first turn on ignition. Plugs come on at start and periodically during a drive for environment reasons.
If the engine is warm it can start  without glow plugs.

Re immobilisor light what do you observe. Does car symbol stay on without key symbol? = correct status.

Have you checked for codes?

Check for loose connections (electrical  and vacuum )under bonnet--take cover off motor to do this.

It is indeed very annoying especially when you are in a public area and people stare at you trying to start your car... Mine is just 4 years old.

Thereís a glow plug light that comes on briefly when I turn the ignition on, itís at the bottom of the Rev counter.

When I turn the ignition the car symbol with the black key in the middle comes on and stays on until I start the car then it goes off.

Annoyingly (?) itís not done it for a few days now, starts pretty much immediately or on the second turn.

Would poor glow plugs cause economy issues? The MPG is 36-37 round town but lots of shorter trips and itís been remapped but itís still the least Iíve seen since the remap couple years ago.

Plugging in show faults even though ECU light not come on?

Cheers for the replies guys :)

Good, Thats what you should see.  :goodjob2:

I cant comment on glow plugs because I dont know their condition, age etc. Need to be measured with meter.
