Car is 08 1.6 diesel 90hp. Had economy mode coming up on dash so checked battery voltage which showed 11.6. Original battery so ECar parts supplied a new one. I followed the fitting instructions from this forum reset the clock and all was OK. However economy mode has started re appearing and when starting the iginition warning light flashes. Current voltage is 13.3 and over 14.00 when running. Interrogation with PP2000 shows one fault code P1351. Anyone any ideas why the car is going into economyn mode to save battery power. No problems starting and car seems to be running ok. Problem is I have a 600 mile run scheduled fro Friday and am a little concerned.

As well as Battery Voltage there is also a timer which will switch to eco mode after 20mins of sitting without engine running but ancillaries in use (even door open when cleaning etc)

P1351 is probably one of the most common faults I've come across on a 307 and could also be the same with the 207. Unless you have a DPF (which you probably haven't) or you are trying to start the car in a Siberian winter it won't really cause any issues.

The code points to either the glowplug relay, one or more glowplugs are faulty or a problem with the glowplug wiring.

After Economy mode has kicked in, once the engine has started it resets it but only by twice as long as the engine has been running up to a maximum of 30 minutes use with the engine off. It's possible you have something drawing current but the only way to tell is to put an ammeter in series with the positive supply while the car is stopped with the doors closed and everything switched off. There will be a small current draw but it will be a few milliamps to allow the remote locking receiver and central locking system to remain in standby. Any significant current drain would cause economy mode to kick in and possibly shuit down whatever is causing the drain on the battery.

Cheers both replies. Car does not have a DPF and is starting fine and running OK. I will attempt to check for a current drain and will report back. Although not in Siberia I am in Scotland and temps can drop as low as -15 in winter. I'll keep an eye on things as the weather gets colder. Again thanks for the help

Even at -15 the car would actually still start with the glowplug fault !

The weathers ok here now unless your in thurso its not going to be a problem we still have 2 days of sunshine to come for our summer :)

By chance last week a friend at work was having trouble with battery drain, he was advised to get a tester to locate the source of the drainage.

He got this 400mm Automotive Current Tester Mini Blade | Maplin

Have not seen him to ask what his problem was, but for the price it looks good to have in your toolbox.

Yeah as stated p1351 is part of the glowplug cirucit, probbably one of the elements has burnt out, but you can ignore it as they're more of a pain in the arse to change than they're worth! Plus they only pre-heat below 0 celcius and then its only 0.5 seconds

OK guys thanks for all the helpful answers. Economy mode appeared first thing this morning but it has been absent since then. I'm going to charge the battery up to max and see if that makes any difference. One again thanks for all the helpful input.

I have never come across one of these before, im interested, my question, does this thing just do a voltage drop test or does it read amperage somehow?

Well as it states that it is a current tester it will measure the current (amps) that would be flowing through the fuse it takes the place of.

Well seen him and it helped him a lot. So his solar panel fitted to motor home to keep battery charge was faulty, it was using power, but not charging.
