Default Coding a replacement ABS ECU

Hello folks, my first post here on the forums...

Peugeot 207, 1.6Hdi, Sport, 2008. approx 22000 miles (annoying eh?)

I've been suffering progressive worsening of everything associated with the ABS unit (so what's new?). It started a while back with the "braking system faulty" and has progressed all the way to no speedo, no power steering, STOP light etc. You all know the routine by now. Car runs as sweet as a nut though.
I have a PP2000 & interface and was able to read the codes until recently and was getting a pretty random range of various sensors open/shorted/no repsonse/vehicle too fast etc etc. These symptoms/reports were not consistent though. I even fitted a new front left sensor in response to a specific message. It didn't make any difference. But now I have lost all diagnostic contact with the ABS. I can still see/interrogate BSI & ECU and operate lights/central locking/ horn via BSI and also EGR valve for example via engine ECU so I think my basic diagnostic access is generally OK.

I plan to get an exchange ABS ECU but I am concerned that it will need recoding in some way - even assuming I get an EXACT replacement with same part number. Since I cannot read my own ABS ECU any longer, I don't know what parameters are likely to need recoding (if any).

Please can someone advise on the likely pitfalls/requirements of having to recode the new ABS ECU with PP2000? Is it just a case of obvious things like wheel/tyre size, manual gearbox etc or will there be some parameters that I won't know the answers for?

Any advice?

Thanks

Funny(!) you should ask that.
I did contact the local dealer, especially given the lamentable history of ABS issues, but since it's now getting on for 2 years out of warranty they weren't going to co-operate.

Cheers

We had a power steering pump replaced by peugeot on a taxi and it was out of warranty by 1 year.

Some parts should last the life of the car i would stamp my feet as you say it is a known issue.

No issues with re-coding as you say just transmission and wheel size etc.

I have yet to hear of anyone near me with a 4+ yr old car getting pump changed with any help from PSA even with the well documented issues, maybe they should get rid of any doubt by adding it to service schedule like a cam belt

I bought an 07 plate HDi GT w/35k on it last month, and 600 miles of driving and I got the ESP/ABS error. Thankfully, its just the ESP light on, so was completely driveable. The warranty place have refused to pay their 'upto 1000' claim limit with me paying the remaining 400. Peugeot quoted 1400 btw for new pump and fitting. I have since fitted a new pump/ecu (for considerably less wonga) on friday morning. The mechanical side was fine, fitted in about 90 mins or so, but the bleeding took forever with the PP2000 actuator cycle. The programming is just that screen with the 5 or 6 options on. -engine, -wheels, -rear discs outside. Inititally, set it through the 'New part' menu, but it may need to be the DV4 engine first, but then go through the ECU menus and set it correctly! Job done!! I instantly had faults flying up about headlights, speed sensors, and a few others, but 10 mins of driving, and a clear of the faults solved it all. Think this was because my pump was brand new and needed to read all the wheel, speed, yaw data for a bit.

Hope it all goes well. It stinks having a nice car with faults.

Windy1603, Scoppack,

Thanks for your replies. Sounds like it shouldn't be too hard.

Scoppack,

a few questions please:

1) Did you get a brand new pump/ECU or a recon/exchange ?
2) Did you get an exact match (part number) or did you get close (in some way) and were then able to recode it to make it a perfect match.

Thanks

1) Did you get a brand new pump/ECU or a recon/exchange ?

Thankfully I managed to get a new pump. It had no values in the ECU at all. I think thats why it threw so many errors at me initially. From research, I'm unsure as to if my pump (combined ECU/Pump) can actually be separated properly. There are no screws in the back of it.

2) Did you get an exact match (part number) or did you get close (in some way) and were then able to recode it to make it a perfect match.

TBH, I could not find an answer to this, so I got an exact match.
I looked for the 966xxxxxxx number off the barcode.
It seems from Peugeot's catalogue, that there are 11 types of pump fitted to the 207 range. The Peugeot part should be along the lines of 4541.xx, and so any part matching that will work. Or matching the 966... or 956... or summat. It doesnt seem to matter about the ECU number, or the lower number, think they're batch/item number rather than actual part/type.

If anyone does know if you can fit an ABS labelled pump to an ESP car, but then 'absent' the ESP in Planet, I would be very grateful. As this may save a fortune if this happens again.
Sorry I couldnt be more help


*EDIT*

Do you know the part number you need? Do you have your VIN?

Hello,

the part number I got from a photo I took:

9662150680

10.027 - 0077.4

I don't have the VIN handy tonight.

I've been told that the following will (can be coded to) work.

9665343980
10.027 - 0159.4

Do you know?

Cheers

Those 96 numbers are only manufacturer numbers. The proper number is the actual Peugeot part no. Theres no way of telling.
