OK, my 2000 2.5 TD engine ECU is fried, when I get a replacement, is it just "plug & play?" OR do I need the transponder & key chips? I just need a definitive answer before I look for stuff I may not need. :-\
-
think you need a tec 2 to sync with alarm and imobliser and key fob.
-
You need immobiliser and key chips.
How was it fried as they are pretty bullet proof!
-
Hmmm, not looking as easy as I was first told then. Any Tech 2s in my area? The ECU was fried by a loose live wire.
-
Long shot I know but are they any internal fuses in the ecu case ?
-
Hello Tigers, you never know, I may as well open mine up & have a look. Anyone ever had one apart? :-\
-
Yeh, is there not a guide (as pr chipping the 2.5).
Simply put, two boards but not seen any fuses.
-
Yes, I have seen the guide, but no fuses. I thought there may have been a simple anti-surge fuse at least. :-\
-
There may be some zero ohm fuseable resistors on board....check the tracks also!

Good point, however, some of us have no idea what you are talking about. :-[

Pull the cover off and have a look at the front and back of the circuit board.
The tracks are the metal strips that conect the various components together.
What your looking for is any sign of burning, different colours on the board or signs of over heating :y

Thanks Tigers, I will have a go at it as soon as I get chance. I think I am sorter with a replacement now, just hope it gets here soon with the Bank Holiday etc.

Latest - I now have a replacement ECU, plus transponder, and key chip, all fitted. Tried sync-ing the lot together by locking/unlocking in pos 2. EML still flashing, engine will not start (actually it will but won't run for more than half a second). What am I missing? Does this need a Tech 2 after all?

Experts will no doubt be able to answer you better, but the 're-sync' just syncronises the fob back to the central locking after battery removal etc. It sounds to me as though the imobiliser isn't reading the chip :-\ :-\ :-\
-
Right, yes I agree. The connections are all fine, and the chip is fitted (even tried it taped to the immobiliser/transponder). I just don't know what to look at next.

Andy, you are a star, you fixed it! :y
No idea what happened, perhaps it took a while to think about things, but it's running now. I am one happy bunny. :D

Excellent!! :y :y :y
-
Excellent news! Are we to assume Andy laid his hands on it, or did he just send positive thoughts?
-
......, or did he just send positive thoughts?
Just the thoughts ................... I try not to get my hands dirty when not at work. ;) ;)
-
Mmm. This telekinetic on-board-diagnosis could catch on... ;)
-
Whatever it was, it works :y ECU ESP ::)
It looks like year 2000 TDs need tranponders & key chips with replacement ECUs. Unless you are lucky. :-\
Thanks to "dieseld4" for the spares. :y
-
Just to add, I did not need Tech 2 in my case. :y

Thanks to Marks DTM Calib for the right info, and dieseld4 for the spares. :y
