 Peugeot 307 SW - 20 2.0 Starting issue - El Hombre
Recently acquired a 307 estate 2.0HDi.

It has a strange quirk. To start the car I have to wait for all of the dash warning lights to extinguish before turning the key to start.
If I turn the key straight to start the starter will spin but not engage, wait for the lights to go out and it starts first time.
This procedure is necessary if the car is left for an hour or so, shorter times and it starts without delay.
Apparently it had a new battery recently.
I can't think of any logical reason for this.
Any thoughts please?

Perhaps glow plugs drawing current, preventing starter fully engaging. It is French!

I'd forgotten the hours of fun I've previously had with French electrics

Unless these have some quirky starter motor, I can't see how a pre-engaged starter motor can spin before it's engaged.

Daughter had a Škoda that would do that, but then again, it was a Škoda!

I think the glow plug suggestion is probably the correct one.

Firstly, it’s an hdi engine, so doesn’t need the glow plugs to start . Your symptoms would suggest a problem with the starter motor drive dog or worn teeth on the flywheel.

Yes and no. Glow plugs are instrumental in reducing smoking and are used at all temperatures pre and post starting.

Can somebody remind me how a pre-engaged starter motor works?

If it some device causes the starter to engage before actually powering its motor could said device, solenoid or similar, be slow on the uptake?

The solenoid operates a fork that pushes the pinion out to engage the ring gear. At the same time, contacts in the solenoid close to supply current to the starter.

In the case of my daughter's Škoda, the contacts were closing before the pinion was far enough out in the ring gear. I improved the situation (didn't completely cure it) by fitting a thin spacer (gasket paper IIRC) between the solenoid and starter, thus, slightly, delaying the closing of the contacts until the pinion was further engaged, making sure the fork was fully operating the pinion.

You'd be best getting a Planet diagnostic - look for any fault codes to do with the glow plugs and relay (P1351) and read some live data.

It may even be a faulty fuel temperature sensor. I've had that on a 307 that caused similar issues, and that failed part didn't put on an EML. It was only when reading live data that I saw the fuel temperature was wrong.

Google "Planet owners map" to find a fellow Pug owner with the kit who will be happy to do you a scan for a beer.

Looks like a starter / connection issue. Don’t think any diagnostic test will resolve this.

Thanks.
Waiting on Planet etc and hopefully get it on a ramp to check the security of the connections.
