Good morning, I have had a long standing saga with my 607 with problem after problem which have just seemed to be unsolveable. Finally found a really good Pug mechanic with the full on Diag 2000 kit who had a look at clearing my ECU down for me. To his surprise I had many many perminent errors (many of which should now be historical and he is surprised the car moves), on trying to clear them down he was getting a communications error every time and could not do anything with it.
He said that he has never seen this before and it could be the ECU that is a fault, on the other hand he has never seen a bosch ECU go wrong like this before so it is more likley to be a wiring problem. The really odd thing is when he checked the mileage my car has done the ECU is reporting a meer 87,000,000 km (I haven't added extra zeros, it is eighty seven million kilometers). Now I'm no expert but I think that would make my car a record breaker as it's over a million a year.
Has anyone experienced a similar issue? I think this is the ECU rather than wiring, can anyone recommend a good recon ECU supplier?
Many Thanks
Adrian

A Diag 2000 is totally obselete and won't have the late EDC's program; I'm not surprised it's throwing-up garbage - HDi's do that if there's a software mis-match with the scanner. ["Engine coolant temp is 255C" is a common one...]
Get it read with something with current updates and the right protocol; a new ECU for one of these is over a grand, fitted and coded. [Very, very, rarely needed. Pug fit 100 new fuseboxes to every 1 ECU.]

ECU's don't often go wrong;in most cases,it turns out to be one of the connectors-either to the ECU or one or more of the sensors.

A Diag 2000 is totally obselete
Was this obsolete in 2000 when my car was made? He did check that my car was old enough for his kit to support before I took it and when he plugged me in my chassis number details etc. were on the list on his device to choose from, this would suggest to me that the diag 2000 kit should work fine with my car?
The guys who have tried to work on it before and couldn't clear anything down had the newer laptop based system but I wasn't with them when they did it so didn't get as good an overview of the issues as I did this time.
The kit can read the errors fine, he could even reset my fluid counters (which the last place couldn't) he just gets a communications error come up every time he tries to reset the fault codes.
I have however managed to dig out the main ECU (which is a pig to get out) and take the plug off (as I needed to get the model number off to see if I can get it tested), I noticed that the plastic on the plug where the bottom pin on the hinged side goes in was damaged and pushed into the hole. I have no idea what this pin does but theres a fair chance it had a bad or non existent connection.
Have cleaned this up and will see if this helps before resorting to sending the ECU off for testing.
Thanks for the addresses adverse camber, I have contacted both for a quote on a test and possible rebuild.

The Diag goes back to the mid-90s; but if it's lists your car it should give sensible readings. The fact that it doesn't makes me think that it's not to be relied upon.
You have the one-piece plug? Any [tiny] number on that loose pin hole? Might be significant and I'll try and ID it's function with the pin number. Is it a big terminal or a small one and is it offset outwards from the "top" row?
