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.
