Hi guys,
Long time lurker, first time poster from down-under. Thank you all for the wealth of information so far!
My car won't start It appears my ECU has failed as I can no longer communicate with it via pp2000. I've been told that I need to replace the ECU for a ridiculous price but I'm hoping to save some money by locating one myself.
Is this just a matter of buying an old ecu and plugging it in? I've read that I might need a matching ECU/BSI/key set but most sellers in the UK are selling ONLY the ECU.
The ECU number is a XFZ Bosch MP7.0 9625552680
It's a 1999 406 v6 Manual D8
Thanks in advance!!
Gil

Re: 406 v6 XFZ ECU not working
HI Gil & welcome aboard.
Usual practice as far as I know is to buy the set - ecu/bsi/key(s). I've had a quick look and haven't found anything suitable offered for sale in the UK, but there is one advert for someone selling a complete 1999 3.0 coupe for parts - maybe this would work?

If you haven't already done so, check out the coupe forum as the 3.0 engine was more common in those vehicles and potentially more have survived.

Best of luck with your search

Thanks for your quick reply. Glad to be on board!
I should have mentioned my 406 is actually saloon SV. Does that change anything? Can a kit from a 406 coupe still work?

Hi, welcome.
There is a fuse for the obd port - worth a check...
And the ECU should be the same, the only real differences are in the BSI menu regarding window dropping, auto close windows etc - easily rectified with PP2K.

Thanks Ginger, some good advice there.
I was able to connect to the BSI and other components but not the ECU. That rules out the BSI fuse then?

Re: 406 v6 XFZ ECU not working
Probably, but not for certain. The engine ecu uses a different data connection to the other devices, (the 'K' line I believe) so its possibly also a different fuse. Fuseboard layouts vary so it's definitely worth thoroughly checking every 10A fuse in the engine bay fusebox, or all the small fuses for that matter.
May be a long shot but could save you money/embarrassment like 'someone I know'
