Unhappy Peugeot 307 2.0 HDI alternator belt change confusion, Antipollutant fault

I have a peugeot 307 2.0 HDI 2003, I've owned it for the past 6 months and in that time it's built up a list of faults: it currently has Antipollutant Fault, diesel additive minimum level, passenger airbag deactivated and I'm currently in the middle of changing the alternator belt that slipped of yesterday.

Alternator belt- this has totally confused me and my father as the belt slipped of yesterday and caused the battery charger fault sign to come up. So we decided to get a brand new belt and fit it today, however there are 2 different types of belt, 1 for the models with aircon and 1 for the ones without. My car has an aircon and so we bought that belt type, we compared it to the old belt and they are the same size. However when we have tried to fit it the set up of cogs is that of the model without an aircon, the belt is too big but we cannot work out how as it is the same size as the one that has come off. We have checked for missing cogs and there are none missing. The aircon has never worked since having the car so we think it may not actually have one and that's why the belt we have is too big and the 2 exta cogs are not there... But then why is the belt we bought the exact same size as the one old one!?
We now have the other type of belt for the model that does not have aircon and it fits perfectly... We are still not happy tho as something cannot be rite as the belt that come off is the other type. No cogs are missing. Very confused can anyone explain what has happened?! We have the 2 installation diagrams and checked everything we can think off!

Passenger airbag deactivated- the airbag has been checked and its all there but displaying this message. Iv bought a new switch but this has nothing to do with it.. Switching between on and off does nothing it just stays off. No idea why.

Diesel additive minimum level- the diesel additive was filled up but the counters were not reset this caused the anti pollutant fault to come up and now the car is in limp mode. Any suggestions on cheapest route to fixing this?

With regards to the belt, I would suggest that if it's the same size as the one that you took off, then it could only be the belt position that is wrong.

Passenger airbag, can't really comment on whats wrong, and the anti pollutant fault is a message that is quite common to 307 HDI owners

You may need a diagnostics on it with PP2000 to check the faults. You will definitely need it to reset the counters for the additive.

PM me if you need PP2000.

Well that's what we thought, we've tried everything.. The belt is definitely the correct one as all the manufacturers supply for this model. It's exactly the same size as the one that came off. We've put it on the same way as it came off which is the same as all guides suggest. We've tried adjusting the tensioner there is nothing else we can possibly do.

Also I have pm you about the diagnostic thanks for the help.

If the belt is the same size as the one that came off, then logic would imply that you are trying to put it back on in the wrong order. Perhaps the diagrams you have are incorrect, where did you get them from?

Passenger airbag: The GF occasionally gets this, she switches the car off, turns the passenger airbag off then on again and the light goes out just fine.

Smile Alternator belt

Had the same problem with my belt coming off, it caused warning lights for Passenger air bag to come on and an A.B.S warning light fault.
However back to the belt being to big, This is exactly what happened to me and i had the old belt un-damaged but just slipped off (as i thought)
but after checking a diagram on-line i attempted to re-fit and found it to be to big.
After closer inspection i realised there was a small roller missing below the Alternator.
The stud that should secure the roller to the bottom left of the Alternator was sheared.
My model is the 307 sw hdi 2002 with Air Con. Thus the belt should have 5 different Pulleys//Rollers//adjuster to fit around for the car to be Perfect.
So far i have got a new stud//bolt and a new roller//idler.


Went out today after my weetabix and attempted to remove the Alternator.
Disconnect Battery 1st then i removed the two connections on the Alternator and then the two top bolts all within 10mins. An hour later i have gave in as the Alternator wont come off and my body is in agony from health problems.
Back to the Google Board and after a bit of looking and reading here and there i have found that to loosen the bottom right hand side of the Alternator is nothing to do with the bolt with the Hex head with the Oil Filter Blocking you getting an allen key on. (The through Bolt)
If i have read it correctly there is another bolt going in the direction from the front of the car towards the rear. Situated out off sight but you will feel it with your hand slipped down the front off the Alternator to the left of Oil Filter.
Will try this Tomorrow if i can move my sore bones.
Got a picture on-line off the same engine with Alternator removed and i can see another bolt (wee Bastard) looks like a Hex 6mm ?? could be an 8mm. How i wish i was able to confirm it and do it now. Hopefully this when loosened will release the Alternator and let the Dog see the Rabbit. If this removes the Alternator i am hoping to be left with a bit off broken Stud hanging out the bottom left hand hole, if not im beat.
Unless i can get the Alternator Bracket off and replace it (looks like 5x13mm bolts secure it to the front of the engine. But that will be worst case senarrio. Hope this helps someone somewhere get back on the road,cause its been 30 days since this happened to me and due to terrible weather and poor health i am only putting it all together now.
Well hopefully Tomorrow. Thanks Ian C

(PART 2) Friday 21st NOVEMBER
Well the weather was dry and i pushed my-self out the door keen to get this problem sorted.
As i said above there is a bolt 6mm Allen key, just enough room to get a couple turns and hey Presto the Alternator was as free as a bird. ok now the Alternator wont slide far enough to the left to remove it from the broken roller//idler bolt//stud.
It seem`s as though the bottom right pin the Alternator sits on is tight to the Alternator. A few chaps with my Hammer and its still holding on. Then my Back Broke (literally) Though i was going to have to crawl back into the house. I was only out there 20mins but the games a bogey. Tell you something, its a good job i decided not to video it for You Tube (pmsl)
Will try again Tomorrow.

(PART 3) Sunday 23rd November 2014
Well Troops, Today i went out and used a long 3/8 extension bar and a long flat screw-driver & Hammer and got the Alternator off, by 1st hitting the screw-driver in-between Alternator bottom left mounting point & Alternator Bracket.
I was suprised at how quickly i got the Alternator off. I was then able to see the broken bolt and to my amazement i was able to remove it with my Fingers. So perhaps this is why it snapped, if it had loosened off. It looked very newish looking and it was a clean break. Maybe done by the last owner as i only had the car since June (5mths)
So i put Alternator back on then the funny looking bolt//stud screws into bottom left of the Alternator. Please Note before doing this i should have put some lock-tight on the threads to prevent it vibrating loose. What a Fool i feel now as its all built back up. Had to borrow a 15/16 or a 24mm (both same size) spanner from my neighbour to tighten the Bolt, Best way is from below if someone can position your spanner for you. Tightened it very much i felt any more it will snap. Should have used lock-tight. :-( Place the roller//idler on and tighten the nut with 13mm spanner.
I have replaced the belt as after closer inspection the tracks had a small bit of damage about the size of 5 pence piece. (easy to miss) so worth checking all the belt tracks if using the one that came off.
Getting the belt on was a bit of a Mission,but make sure you see a Picture of how it should go. I googled diagrams and thought i knew what i was doing but could not get it on (to tight ) So i came in a had a coffee//Smoke and managed to Google a Picture of the same engine that had been taken out of a car and i was able to see it was different from the way the diagrams where showing me. (Maybe this Picture is Wrong) Can i add a Picture on here ??? Well that was easy. Picture added that helped me fit my Fan-Belt.
I Tried fitting the new belt the same way as in the Picture, I used 2 spanners to push the top adjuster back towards the Wind-screen. I was able to put another spanner through my top left engine mounting which helped hold the spanners and adjuster while i lay under the car, (had to jack up Drivers side) Safety 1st make sure Handbrakes on and its safe to go under without the car falling on you. Fiddled about with the belt and only managed to get it on 92% off the way.
I was putting it on the A/C air conditioning Pump//Pulley last. (from under the car) My son appeared and i got him to hold the spanners back on the adjuster and this helped me get belt on another few Tracks.
It was now Dark O`Clock and im as weak as water. So i deceided to connect the battery terminal up and took the spanners off the top adjuster, (get everything clear from belt area) I turned my ignition on as if to start car making sure its out of gear. This wee Trick got the last bit off the belt on-to the A/C pump pulley :-) Happy Days.
But not so fast, My Battery is to low to start the engine. Some power left but not enough.

5PM on a cold Sunday evening so i have given up again and updated this Book i am Writing lol. Yes i have got better thing`s to do but i know how frustrated i have been Trying to find this kind off information So for anyone reading this and saying Brilliant this is my situation and i know what to do what to expect then i am Happy to have helped.

A Question for any experts out there, How do i overcome a flat battery in this situation.
Do i get a couple of bodies to give the car a push (as im near a hill) and with my ignition on bump start in 2nd gear ????
Or do i get a friends car and use Jump-leads to start mine. ?????
Or should i get a mains battery charger and run an extension from my house to the car and charge the battery. IF SO HOW LONG ????

Jump leads looks like my fastest cheapest option but is there a Danger of Damaging any E.C.U units ???? If Yes can this be avoided by only connecting the Red Positive jump-lead to the Positive Terminal on my car and Put the Black Negative jump-lead on a Bolt on the Gearbox to act as an Earth ???? (seen this done a few years back with Rovers)

VERY IMPORTANT Just Read this from Somewhere else on this Peugeot site. VERY IMPORTANT


Whenever a vehicle battery has to be dis-connected, switch off all equipment,
interior lights etc, close the doors leaving the drivers window open.
Switch off the ignition and remove the key and any DIAG equipment.

Wait a full 3 minutes before disconnecting the battery.

The BSi must be allowed to go to SLEEP i.e. into "power save mode". Do not
operate any equipment on the vehicle during this time. Remember, even
opening the bonnet will wake the BSi on a vehicle fitted with alarm.

If the battery is under the bonnet, open the bonnet first and leave it up. 807
batteries can be dis-connected through the drivers window, remove floor cover
first. (note, Pics are under the passenger seat)

ALWAYS disconnect any DIAG equipment and do not operate any plips from
other vehicles during the 3 minute waiting period

Unless otherwise instructed by Product Service, you must always
carry out the following procedure, often referred to as a "soft re-boot", to
minimise the possibility of the BSi corrupting its own software when
reconnecting the vehicles battery supply.
Ensure the procedure for battery disconnection has been adhered to and
importantly all BSi functions were switched off with the drivers window left
1 Close all doors
2 Remove ignition key if left in ignition
3 Reconnect battery. DO NOT open any doors
4 Wait 10 seconds
5 Switch on headlights through the drivers window (you will hear a "bong") (note: Snap-on says Side-lights)
6 Switch on ignition then start the vehicle and check system functions

NOTE: Upon reconnection, if any vehicle function controlled by the BSi i.e .
interior light is switched on,the internal operation of the BSi has the potential
to spike or corrupt its configuration and software program......

See What I Mean Troops. We need to have the Knowledge to work on our own cars. If you can afford it let the Experts fix it but if like me you are too ill to work and you have a Family to Support on Benefits then do your Home-Work before you attempt to Do-It-Yourself. What i have Written Here is a True Account of my Experience and i have 20 yrs working in the Fast Fit Industry and my own tools etc. But i DONT want to be held Responsible for any damage Happening to Anything or Anyone due to Following my Instructions on here. Im only Trying to Help Others with the same Problem and Vehicle

He wont tell you as he wants you to buy from Peugeot!! Quite honestly, for the price, I would just get it from them, save you loads of hassle.
Just one comment on the thread. I would advise you to start a new thread yourself instead of digging up historic instances as people sometimes will just ignore the thread seeing the date, like I nearly did, and you might lose some valuable info as they do not have time to read through histories! By all means add the info in your text but start a new is my recommendation.
