I've a few problems with the car I wonder could anyone give me their views on them!

I've less than a quarter of a tank of fuel left and I've only done 160 miles - all of which are 3 mile each way trips in to work in the morning and home in the evening. Overfueling?

The last few mornings I've had to turn the key two or three times to get her started. Cold Start Valve, it's not been that cold to be honest?

Twice in the last week while driving down the road the radio sounds like its about to st itself and the car seems to want to conk out, the dash board lights fade right down. If I can stop I give the car a good rev turn the radio off and everything is back to normal. When it has happened the exhaust is popping away / misfiring at idle?



Last bloke replace these in June:

Fuel filter
Battery
Coil
Ignition module
Distributor Cap
Rotor arm
Air flow meter

Thanks

Alternator. Common fault apparently.

Won't start at all now, lots of clicking.

Alternator fan turns for a second or two but nothing happens, just a lot of noise.

Would it be a combination of the starter motor and alternator?

confused

Your battery is shot. Either because of the three mile trips each way when its been on its last anyway or the alternator is shot.

Did the battery light on the dash work properly before the stoppage. i.e. on with the ignition but off when the engine was running?

Get a new battery and put a volt meter accross it with the engine running. Should be in the region of 14 volts give or take a bit. If its less than 13 or much more than 14.4 volts suspect the alternator.

All the lights radio etc still work.

The battery light isn't on now, can't remember what it did before to be honest - I don't think it was on.

Strange.

Sounds like it could be a few issues.

If it bump starts and runs OK it could be the wiring to the starter. They are known to be poor. Its pretty easy to fix if you know what you are doing.

If it doesn't bump start or does but doesn't run cleanly then suspect the alternator.

No battery light on the dash indicates that it may have been removed to mask an alternator fault.

Good luck.

Thanks, will try and get it bump started over the weekend.

Hi, have had a similar issue with my 205. If the battery light is off with the ignition on and engine off the most likley cause is a broken exciter cable ( the exciter cable doubles as the warning lamp supply) the most likley place for this to fail is at the brown multi connector above the gearbox.

Hope this helps

Mechanic replaced the alternator this morning, everything working well.

Just need to sort out the mpg issue now.

Thanks everyone.

3 miles at a time journeys aren't going to be helping it. Walk or get a bike.

205 GTIs can be tempramental, they need to be warmed up slowly.

All sorted now, got a new battery and it was brought round to an auto electrician who found a broken wire.

Now back to normal for a while!

If your mpg is bad it is quite common for the ECU temp sensor to fail, more noticeable this time of year. It's colder now so the ECU will be told it's cold all the time even when its warmed up.

They are about £12 from GSF.

Ha! Another problem.

Car wouldn't start for me this evening, turning over ok but not firing up. Would it be the starter motor?

The last few weeks it's also been running very hot - at one stage the STOP light came on. Turned the heating on full whack and went off after a minute of two. Any suggestions what that could be related to?

Cheers chaps.

How could it be turning over if the starter motor was broken?

Mine did something similar, try following the negative battery cable to where it connects to the gear box, undo the nut and clean the post and the rings on the end of the earths also connected. I also replaced the neg cable and also the positive cable from battery to starter, and the cable from starter to alternator. I also replaced the cable from the battery positive to the shunt box that is mounted near the slam panel / passengers head light. The dodgy earth was the issue on mine but thought I may as well change the cables as like you I'd already changed battery and had a confirmed dodgy alternator so seemed logical to change what connects them all.

No idea, it was just a guess - I've zero knowledge about what goes on under the bonnet I'm ashamed to say.

Will leave the car up to the mechanic today if I can and get him to check this.

Thanks

The AA came out to see if they could get it going. Bloke reckons it's something to do with the fuel pump relay. Got it started and left it with the mechanic / auto electrician.

I know it sounds obvious but when an old Peugeot tells you to STOP you really should STOP.

When they run very hot you can do serious damage to the head. By the time the warning lights start jumping up and down it is often too late. Check that you have enough water and that the fans/thermostat are working as they should.
