Engine issue

[Cymro]

So when i stop engine 1.5 diesel the engine doesn’t cut out straight away. The dealership says they tried other Cx3 and they were the same. Asked them today to check injectors for leakage answer was no. Anyone else had this issue car less than 6 months old

I have a petrol model and noticed the same thing. Easily solved for me. When you stop (not in an emergency but normmal braking) it sometimes doesn't shut off. When standing still push the brake pedal a little more and it should stop the engine.

Better still, try to remember to switch the damn thing off before moving away, unless of course you don't mind it.

Cymro - can I suggest two things :-

1) Have you tried carrying out a Search on this site for the iStop phrase? The Search box is at the left hand very top of the page above the cx-3forums logo. You'll find plenty of postings about potential iStop problems and answers, including this posting :-

2) If you add your approximate location details to your profile and a summary of your car details e.g. engine type diesel, automatic or manual gearbox - to your profile signature then this will help other forum members when answering any questions or queries you post. For detials on how to do this, please read this posting :-

Good advice. Switching the i-stop off soon becomes as automatic as putting the seat belt on.

I don't think the OP is referring to the istop function

I'm reading that when he switches the engine off it doesn't immediately switch off.

If that is the case then the term used, or use to be used in my day is 'engine running on', which is not normal and shouldn't be happening, especially on today's modern engines. I would suggest if the op isn't getting anywhere with his dealer then try contacting other dealers for their opinion.

A little surprised no other deisel owners have commented. Few and far between perhaps.

Our fuel economy monitor says "i-stop has saved you 8.4 miles". Assuming this is the average figure since buying our brand new CX-3 over two years ago, we are humbled by the fact that i-stop has provided a total fuel saving of just £1.26* We're planning to celebrate soon and feel proud that we've saved the planet in our own little way!

* 4.546 litres x (ave.) £1.20 per litre = £5.46 per gallon.
£5.46 per gallon divided by (ave.) 37 mpg = 15p per mile.
i-stop saving of 8.4 miles x 15p per mile = £1.26. Whoopee Doo.

This has nothing to do with istop. It’s to do with the engine running after stop button has been depressed. It might only be a second or two but as far as I’m concerned this should not happen. My local garage had the car for about one and half hour. They said they injectors were within tolerance surely they would have had to strip them down to test? Any thoughts on this thinking of going to another Mazda garage to see if they say any different (tried other Cx3 but they are the same) this is what my local garage used as an excuse

As I said in my post Cymro.
