Post your VIN or at least 6, 7, and 8"th letter/digit off.
Clearing/ "reset" BSI might/ might not be solution, I'd highly recommend scanning with Lexia or equal professional scan tool for errors to narrow down where that foukd originates from. Not popping up on a screen doesn't mean there aren't any and buying a car with "minor problem" might be lot more involved, than it shows, as you haven't no knowledge of what has been done or what hasn't been done or something fitted is incorrect or something like BPGA relay or even BSM being "smoked".
My advice is to get it scanned for errors (codes off), that will be indicator or direction even on what's really happened and what to tackle next.

 

Hi,

yes, I will surely do a scan as soon as I can. My VIN is VF38BXFXA81188321. And yes - I’ve already tried to reset the BSM but with no success. I know it´s always a gamble buying a used car with problems, I could not pass this one up though - a one owner car since new, 150 000 km with a full service history (my first Peugeot, but I´m familiar with old Citroens). No rust, which is almost unheard of with the salt infested roads in Sweden.

Most likely it'll remain "mysterious" problem, unless you'd find some sort of a "specialist", but knowledgeable with those cars.
Indeed, you did the right starting steps as in checking fuses/connections on BSM, then BSI resetting procedure, but TBH, bit of a sympathy apart, I can't advise you any further.
BTW ssg.asia didn't recognise your VIN.

Hope you find this useful.

 

Thank you so much for your effort to help me out - I really appreciate it! It seems though that I have a different ABS control unit on my car. In the enclosed diagrams it refers to a 25-way connector to the ABS control unit. On my ABS unit a have a 15-way/pin connector. When a do a search on “ABS unit Peugeot 406”, most units have a 25-pin connector, so mine seems to be not so common. Could it be that my car has ESP?

 

Could it be that my car has ESP?

No more likely it has basic ABS, because ESP requires more connectors, not less.

 

Well, I think the car has ESP – at least it has a button to turn it of and a message that says “ESP/ASR not functioning” . I may be barking up the wrong tree, it is perhaps related to something specifik to the ESP/ASR system? I read somewhere that a faulty brake switch could cause these symptoms. Anyhow – I will get my car scanned for codes next week so I get more directions

 

ESP might be a separate module then or might be part of the ABS, didn't see anything on my initial look. I have a look if you can supply the DAM/RPO number.

 

I´ll really appreciate that! If I understood it correctly it should be 0872389.

So this system

Think the reference is dates
until 1998 06 01
after 1998 06 01
So appears to me 4541 44 OEM number but doesn't appear to 100% match, which is perplexing, the connector is wrong position in these drawings, matching 5.3 ABS ~imo.

So the above document attached before Type 1.
or Peugeot reference: B3GZ02K1 Schematic diagram:Anti-lock brakes

Should be the correct information, the RPO didn't help in this case as SEDRE, has no information about the system, there is not anything else I can add from Peugeot Workshop Manuals or (Sedre) Electrical wiring digrams for this.
Started searching for any ABS unit with a 15 PIN out, no luck, not something have seen before with ESP.

Come across this C1 454904 RV Bosch 0265410040 JH which appears like ESP system for 3.0 V6. This is me searching for something trying to explain, in my mind, why the ABS seems like just an ABS and why the connector, why does not match a typical Bosch ABS 5.3 or even 5.3s connector(s) (the normal ones or ones I can see).

Historically, the evolution of Bosch ABS/ESP

Not totally related, but an interesting read, was this BL BOSCH 5.3 ABS. System Description of BL ABS - online presentation

Hope this is useful.

 

Thank you again for your efforts RedSector! Yes it´s a bit of a mystery why the units doesn´t match. When I search the pump number (96 328 335 80) it seem that the pump (with the 15-pin connector on the ECU) usually origins from the 607 or the 406 coupe.

 

Update

I took my car to the workshop today and got it scanned for codes. It turned out to be a faulty steer angle sensor that was the culprit! I´m not sure witch sensor I need, but after a quick search on the interwebb it seems that it is a BOSCH 0 265 005 404 (EAN: 3165143515334) that I want. Can someone confirm that and if so, do I need to programme it? They seem difficult to find new, but they are available second hand.

Thank you for all your help!

 

Happy days – I can confirm that the steering angle sensor needs to be re-calibrated with PP2000. After re-calibration everything worked fine for a couple of days until suddenly both ABS and ESP warning lights lit up again. Fault code pointed to a faulty ABS sensor on the front right wheel. After confirming the fault, I replaced the sensor, and the warning lights stayed of for another couple of days – then the lights came back on again. Fault code this time pointed out a faulty break light switch. After replacement everything worked as it should, and after a couple of weeks, it still does. What are the odds that all the common sources for trouble with the ABS/ESP happens within a week?
