You maybe better off to go for a ECU&BSI kit from eBay or similar. Other than that you need the same part no BSI and then need to read or remove the eeprom chip and swap/write to the replacement BSI.

Are you 100% BSI is damaged and it has just not got corrupted and lost key codes

 

Thanks for your response, yes it was checked by a peugeot rewire expert and he told me the BSI is damaged due to the water that got into it because water use to be in my car after it rain and he also told me the water enter the car through the wind screen side and he said I will need to seal the edges of my windscreen to avoid the rain water getting into the car. So he said the BSI got damage due to the water that got into it

 

If it is wet you could try drying it out on a radiator for a day or two. It worked for me.

 

Is not even wet, but the rewire told me it is damaged after scanning the car with his computer and said is due to the water that got into it

 

As suggested remove the bsi and place it on a radiator for a day or two to dry it out unless you live in a hot climate and if so just let the sun do its job! Try that first before getting into the next stage which can be very complicated.

 

I'm a Nigerian and the sun comes out every day here for this period, may be I will try that but the car was abandoned since it got the issue and is been yrs now

 

A lot of the fuses look damaged and a good clean with a air line might help it for starters.

 

Even some of the fuses metal looks broken which makes me think it can't work anymore

 

As madbadandold says, change all of the fuses and give the plug sockets a good clean. It certainly will not work the way it is.

 

Thanks for the reply. The rewire has refused to do anything and keep telling me the BSI is damaged so I needed to get another complete brain box but the problem now is that I can't even find my car type of brain box in the market at the moment.

The car only role when I tried to ignite it then but doesn't start before the peugeot expert came to scan the car and told me is the BSI that is damaged and is been over 4yrs now cause the car has been abandoned since then.
Thanks

 

Even if you could find a new BSI it's not simply a case of installing it. If it's from another car is needs to have its memory cleared and reprogrammed. As Windy suggested it would be better to replace the BSI and ECU with a matched pair. You will also need new keys which will also require programming.

I agree with patspiercing it's worth trying to clean the existing BSI.

 

Clean the BSI that you have got. You have nothing to lose!

 

The rewire did that already when he discovered that is the problem with the car refusing to start and have asked him to come and try it again but he insist it won't work cause it is damage

 

It seems he does not fully understand our advice or he has already "cleaned" it!

 

He did the cleaning some years ago when he discovered the BSI is the problem after scanning it and I told him to come and try it again but he said it won't work that is a new complete brain box I will get

 

What engine is in the car some citroen ECU & BSI kits are interchangeable you just need to match ECU and BSI part numbers

 

Thanks for the information, will see what I can do cause I'm getting fed up of the whole situation already and thinking of selling the car as scrap. Thanks

 

My concern is that you may other issues with your car so before you go any further with this can you give us a bit more information? In particular when you say the car would not start was the starter motor able to crank the engine?

Is the BSI installed in the car at the moment?

The 307 has two fuse boxes. The main fuse box is in the engine compartment. The second fuse box is part of the BSI. The BSI is powered by three fuses in the engine compartment fuse box if one of those fuses is blown it is highly likely the diagnostics will report a faulty BSI.

Do you have any automotive locksmiths in your area? They usually have a good understanding of BSIs so may be able to help you.

 

Yes, it was able to crank the engine and the BSI has been removed and no expert in my area which made me wasted 70k naira on it before I latter got the peugeot expert that discovered it was the BSI that was damaged.

Since then the car has been abandoned for like 4 yrs or so now

 

Have you seen this Dutch website:
https://bartebben.com/parts/peugeot/307/electrical-system/ecu.html This BSI for this ECU kit looks like yours:
Peugeot 307 Ecu second hand | large used car part stock However, I am not sure it is the correct kit for your car because this is for a 1.6l and you said your engine was a E10 which I presume is actually a EW10 (EW10J4) which is 2.0l. I think you need to look at your ECU to find the manufacture and part number. The BSI should also have a part number on the back. If you can get both part numbers it would be worth emailing this company to see if they can help.

I had a closer look at your photos of the BSI and I am a bit surprised your Peugeot rewirer was able to run a diagnostic test. Most of the fuses in the BSI are the wrong size and several are blown. Most importantly the fuses (fuses 10 and 18) that supply power to the diagnostic connector appear to be blown. I think someone has had trouble with various accessories in the past and has been swapping the fuses around. If these fuses are difficult to get in your country someone may have soldered some fuse wire onto the pins under the fuse body.

If you look closely at your BSI photos you will see there is a number on the case below each fuse. The fuses are number from left to right as follows: 15 1 9 18 14 2 5 17 16 4 24 10 23 11 gap 12 7. You can find the fuse details at
Fuse box Peugeot 307 both the engine and the passenger compartment (BSI) fuse boxes are shown see - passenger compartment fuse box type 1.

Wao! Thanks for the information, I really appreciate your observation. I think with all that you have mentioned the best option is to get a complete brain box only if I can find one.
I will look into all you have said and get back to you with anything I got.
Thanks

Good day everyone, please I want to asked for help, I have this Peugeot 307 2002 old model. When ever am driving, as soon as I remove my leg from the acceleration. The car keep shorting, and the sounds come up very loud. Just like someone short somebody. Making people to get afreid .. please what could be the problem. Thanks Paul from Nigeria.

 

Hi Paulow47,
Sounds like an interesting problem but I am concerned it might not be seen by the right people. This thread is on a BSI problem so it might be worth you starting a new thread. It also might be worth mentioning if the noise still occurs when the car is parked and the gears in neutral.

 

Yes. You are right. I have those part number is just that I'm not where the car is right now but will get it in like an our time or so but I have a picture for you to confirm we are on the same track

 

Yes that looks like the ECU. I hope there is a manufacture's label with the part number on the side

 

Yes, there is

 

Dont know which is the part number but that is the number pictures on it

 

Ok, I will do all that. Thanks a lot

 

Let me know how you get on.

The Magneti Marelli IAW48P2.37 (often written IAW48P237) seems to be an unusual ECU. There are a few around on places like eBay but not with a BSI. A Magneti Marelli catalogue I found on the Internet suggests that the 307 with the 2 litre EW10J4 engine normally has a IWA48P2.36.

 

Everything looks correct except the one under the IAW, it doesn't correspond with mine which I sent you in my previous message.

Thanks

 

That number is not not important. I think it's a number unique to each unit e.g. manufacture date code, serial number etc. The IWA number is important number. The two HW and two SW numbers are often quoted as well but the IWA number important one.

 

Ok, thanks a lot. I really appreciate

 

if the BSI will power up you could try and find someone with a OBDSTAR F108 to read BSI and then copy to a replacement unit to clone it then you can keep the existing engine ecu and keys

 

Thanks Windy, I agree the best thing would be to clone the BSI. Apparently Wachocilla1 can’t find anyone in Nigeria who can do this so I gave him a couple of links to some UK companies that might help.

The problem is the BSI is no longer installed in the car and his technician “Peugeot Rewirer” refuses to return until a new ECU Kit (what he calls a “brain box”) is available.

While water appears to have got into one BSI connector I am not convinced it got inside. The fuse that connects 12V to the Pin 16 of the diagnostic connector appears to be blown so I am a bit surprised the technician was able to run a diagnostics.

 

What Windy is suggesting is there is a good possibility that your BSI is not completely dead in which case it may be possible to read the data stored in its microprocessor’s memory and copy it to a new BSI. Unfortunately, I don’t think the tool (ODSTAR F108) he suggested will work with your car (see note below).

While there may be other solutions I think you should still email the Dutch company as we discussed earlier.

While you are waiting for a reply from the Dutch company I think it would be worth doing some more checks on your BSI. I have three questions:
1. Would you be able to reinstall the BSI yourself? You can tell where most of the plugs go by their size and they are colour coded. The labels on the BSI are abbreviations for French colours:
GRIS - grey
NOIR - black
VERT - green
2. Many of the fuses in the BSI appear to be blown. Can you check them? Going by your photos of the BSI if you look at the first two fuses No15 and No 1 there is a wire linking the two pins but if you look at the third fuse No 9 there is no wire which means it's blown and several others are the same (has someone wrapped some wire around the pins underneath?).
3. Is your car’s battery fully charged?

Note
I had a look at the ODSTAR F108 tool and it looks interesting but the description says that it doesn’t support car made before 2008. There is another unit ODSTAR H108 for older cars but I don’t think it will work on a 2002 Peugeot 307. The 2002 Peugeot 307 uses VAN diagnostics and as far as I can tell the ODSTAR tools only work on the newer CAN diagnostics.

If I can get directives, I can try fixing it back to test it but I will need to call on my mechanic to do some work on it cause the car has been packed ffoThanksu

Thanks

 

The 108+ (clone i think) I have says it does BS1 (K-Line) which i thought covered the VAN vehicles (as also list 206 etc).

I have used it on 2003 307 to find PIN but only ever used BSI/Dash dump on later CAN vehicles

Hi Windy,

Thanks for the reply. When I use Diagbox on my 2002 307 I have select the VAN option and it looks like CAN was introduced in 2005 when Peugeot did the face lit on the 307. This was the site I looked at for the ODSTAR F108. It clearly states it can not support cars before 2008 and refers you to another version. However, it also says it can read the PIN of both versions of the 307. If you follow the link to the H108 it lists the BSIs it can handle and all the VELO BSI listed are CAN. The VELO BSI in the 307 we are looking has a HC05 MCU which has its own data storage. The ODSTAR needs to be able to read this data to get the PIN so you would expect it could read everything.

 

I'm sure your right all i can think is on the 307 it may have packet sniffed engine ecu data for pin as I was using existing key routine to obtain pin not BSI read

I suppose the only other option if he can't find ecu kit is to find a virginised unit and program from scratch but the pin is needed to do it

Thanks Windy,

I did a bit more research on the OBDSTAR F108 and I think this review is interesting OBDSTAR F108 Review on Read Pin Code & Make Key for Peugeot Citroen DS – UOBDII Official Blog. I get the impression that it’s the sellers rather than the manufacturer who have reached the conclusion that the F108 is unlikely to work on cars manufactured before 2008. The reviewer tried to read the PIN on two different 307s and it failed. Your experience with a 307 suggest it works on some 307s which is not surprising as there are many variations of BSIs and ECUs in the 307 range.

It still may be possible to clone Wakochia1's existing BSI. LM Auto Repairs has a YouTube video where he extracts the data for the same BSI and clones it. This clearly requires that the microprocessor in original BSI to still work. In which case, I would have thought there was a good chance the original BSI was repairable. The problem is that Wakochia1 has not been able to find anyone in Nigera with the suitable expertise to repair the BSI or even program a verganised unit.

 

Good one, I will look into it and ask my mechanic to help and install it back to see if it will work

 

Once you get the BSI installed please test things such as: the lights, the radio, central locking, electric windows, windscreen wipers etc. The BSI controls all these.

If the car will not start do the beep test by putting the key in the ignition (off position) and open the drivers door and listen for an alarm (continuous beep).
