206SW HDi BSI Issues

[r11co]

This is going to be a fairly long post so bear with me

We have a 2003 model year 206SW HDi dTurbo (2.0) which when we bought it only came with one key. At the time I tried to get an automotive locksmith to program another key for me - this was a secondhand keyfob with a new blade.

If the locksmith had been competent he would have known that the secondhand keyfob would need a new transponder as (I have since discovered) a transponder once programmed into one BSI cannot be set to work with another, which he didn't do, so he failed to get the key programmed (on the plus side he did manage to reprogram in the original key I had and as a result deleted the transponder for the missing key).

A second attempt to program in a key with a new transponder a week or so later produced a strange result - this time the locksmith couldn't get any of his equipment to communicate with the BSI.

I gave up on the guy as clearly he was a bodger and instead I went to my local Peugeot dealership who gave me the bad news that they couldn't get their equipment to talk to the BSI either and I'd need a new one (£££££££!!)

My guess is that the locksmith's equipment has corrupted the software in the BSI.

Anyway, this was nearly three years ago and I've been driving the car around since knowing that (a) if the one key I have gets lost then I am stuffed and (b) if the car needs any diagnostic work I am going to have big problems, but I've been using the time to find out a more cost effective way to solve the problem.

Firstly I looked into 'cloning' my original BSI to another identical second hand unit (I am fairly competent at soldering and programming EEPROMS having done a few in the past), but I don't want to risk further damage to the original BSI as at least the car is driveable at the moment.

So I have established that I can fit and program a 'fresh' or 'virginised' BSI myself using a Lexia 3 and PP2000 but this is a tricky operation fraught with pitfalls.

So, I am looking for advice from person or persons who have experience of these tasks. I have obtained a used BSI which I know I cannot use 'as is' so I need some advice to virginise (or is there someone that can do it for me?!)

The BSI is a Siemens E01-00 9646777280 and contains a 95160 EEPROM. I have read somewhere that virginising this is as simple as writing all FFs to the EEPROM but others are saying a dump from an equivalent virign BSI is required. Can anyone give me a definitive answer?

Secondly, I intend to buy a Lexia 3 with PP2000. Before I do so is this the correct equipment to buy? Also, once I am in the position to do this would anyone be willing to talk me through the exact procedure to make sure I don't stuff up?

Many thanks in advance.

You are far better off buying a blank BSI. You can even if your not sure on the config of the bsi get them configured for the car and you just learn the immobiliser code into it to match the key. But they really aren't that hard to configure.

That's going to be expensive though! If I'm going to do that then I might as well save the cost of the Lexia kit and put it towards dealership labour to do the job for me.

Is there anyone here who has experience of 'virginising' used BSI's? There is no reason why it cannot be done and I consider it a waste that I have to obtain a new unit when I have in my possession a mechanically and electronically sound unit that simply needs expertise to reprogram it.

I`ll post you later as i don`t have time now but you a correct as far as i know , you can code a virgin BSI unit then you will need to configure it but it should work , you will also be able to plug your old BSI back in if it doesn`t .

[chrissy_406c]

I do believe a dump from you original BSI would be necessary.There is a company BBA Reman that can do it. Not sure on the charge. They can also code it with your immobiliser code as well. There was a person near me that claimed to virginise them as I was going to have one a good year ago for a berlingo but never materialised. I just think sometimes better off to buy a new one as sometimes by the time you mess around trying to find a cheaper way it either works out the same cost or more expensive.

in the end of the day, you should of acted on this straight away...proved the locksmith caused the damage and will have to cover the costs of replacing/fixing whatever he broke.

bba reman looks the real deal and i beleive they do exchange basis ecu's. ie you send in yours, they take the relevant files needed, transfer to a a refurbed unit and send it out to you. your original is then wiped, repaired, and sent to a new customer on an exchange...if that makes sense.

hope you get this sorted

@bettyswollocks - thanks for the offer of help I'm waiting to receive the kit I need to virginise the BSI (specifically an SPI serial eeprom programmer) and the Lexia 3.

@chrissy_406c - there is a way of doing it that doesn't require Lexia 3/PP2000 which is to dump the eeprom from the original BSI and then program the contents to the eeprom in the replacement, or if you don't want to mess around with eeprom programmers then simply swap chips. The problem with this though is that the actual software in my original is probably corrupt and this will simply transfer the problem to the replacement. I 'phoned BBA about it and they weren't too sure they could revive my original BSI (effectively repeating what I said above about the problem simply getting carried over to another unit) and suggested the new/virgin BSI route ie. effectively starting with a clean one as the dealer would have done.

The expense of doing this myself so far has been £30 for the S/H BSI, £12 for the eeprom programmer and about £60 for the lexia 3. Dealer quote for this job was going to be circa £500 and even if it doesn't work out the car is still driveable at the moment!

@john_h - you are absolutely right. I should have got this resolved at the time but it was only in retrospect that I realised it was probably the locksmiths actions that caused the problem and furthermore proving it would be another issue entirely.

Well I do hope it works for you fella. Cant see why it wouldn't Curious where you got your eeprom programmer from. One other thing, do you manage to get comms with the engine computer. Would hate to think you only have a comms line fault from the DLC which can occur anytime.

There's an ebay seller from Bulgaria doing them cheap. Price has gone up a few quid since I ordered mine though (probably due to the exchange rate).

I won't know until I get my own Lexia 3/PP2000 hooked up. I would have thought though that the dealer would have picked up on that when they had their go at programming a key. If it is a comms line fault how easy is that to sort (it did occur to me that there might be a simpler solution as everything in the car is behaving as it should and I would have thought that BSI software corruption would have had more pronounced symptoms....?!)

[chrissy_406c]

I was thinking the same thing about the BSI having corrupt software. Usually all the systems go crazy. The dealer would probably not look at this unless you requested. Its not difficult to check. Will be two wires on the can line that will link to the BSI module and loop around a few of the modules on the network. If you cannot get any comms on the rest of the modules then it would be likely the comms lines to the DLC is down.
