It looks like one of those grey areas that is advised due to the fact if the car doesn’t start you are injecting fuel into the Cat that won’t be burnt off. I think in my case as the is a spark is present and effectively ignition it should be ok...?
It makes you think though, if you have a good battery but your car won’t start, constant cranking will cause as much if not more damage to the Cat than a short attempt at bump starting..?

It is ok if the car starts but if it fails to start the unburnt fuel is expelled into the exhaust. It also depends if fuel system is operational or not. The AA man was obviously confident it was a starter problem.

Yes I think you’re right. I’m hoping to bump start the car (quickly I hope!) and drive it to a friend who has ramps etc to get underneath and locate the starter motor..

Bit of an update..

 

The starter has been removed after it was pinpointed as the issue. This is not an easy job as the starter can barely be seen from looking under the bonnet. So much has been taken off including hoses, inlet manifold etc

 

Ive taken the starter to a local specialist rebuilder who tested it and confirmed it being faulty, no parts appeared to be available unfortunately so it looks like a replacement exchange unit.

The repairer had mentioned that with the start/stop function he has come across damaged starters caused by faulty ignition switches or start/stop switches that can send power to the starter while it is being driven engaging the starter motor into the spinning flywheel. Not specifically to this make and model but he advised changing the ignition at the same time.He mentioned that even testing the ignition doesn't alway flag up a fault, it may be many starts later or driving over a bump in the road that causes it.

 

Unfortunately this has made me a bit dubious of the car going forward and think i will be turning the start/stop function off every time i get in the car which obviously negates the point of having it...

There have indeed been reports of a faulty ignition switch causing the starter motor to burn out as you describe.

Ive spoken to Dacia uk and they have told me my model (by reg No) is not affected by any ignition recall..

 

Im picking up a new starter motor later today, not sure how much confidence i will have in the car going forward which is a shame as its been a great car until now.

So I now have the replacement starter motor the repairer had to source a replacement unit from a supplier.

 

He showed me my starter which had failed and he said it had been spinning with the engine to cause the damage that is present. I took some pictures which i will try to upload later, its quite amazing how much damaged is caused.

 

He thinks the fault may lie within the stop/start system which has engaged the starter while the engine is already running.

 

Now thinking about it i remember driving the car on occasions when the stop/start has killed the engine at a junction or traffic lights and maybe a minute or so later starts the engine without the clutch depressed. Not thinking much of it at the time but im now wondering if the stop/start has been kicking on when the engine is running? would you hear it?

 

From what i can gather re the recall on some models for the ignition switch is that there is a danger of the key getting stuck in the cranking position and again burning the starter motor out....but not my model apparently.

 

I will without doubt be turning the start/stop off every time i start the car from now on..

It's been reported that in cars with start/stop there is a cable that goes to a bonnet catch microswitch that stops it operating if the bonnet is open. If you disconnect the cable and insert a link the bonnet is always open and the start stop disabled.

Can't see how the reg.no. would give the build date. As an extreme example, I remember when BL had cars sitting in a field for months before they were sold.

It was Dacia GB that asked for the reg No.. maybe through the dealer they can check.

 

Mind you if you put the Reg No into Europarts website it gives you vehicle year and model. Maybe thats what they did..laugh.png
