Problems and Complications with O2 Sensors on 96 D1

[pavel]

OK Adam - you've got her fixed and running OK - well done! Up here in the wilds of Canada we almost never see a cop....excuse me....a Mountie. The only audience I get during home repairs is my long suffering Mrs. or a porcupine or coyote. Wonder why your ECU took so long to cooperate? On the Volvo I told you about, the oxygen sensor light did take over a week post repair to go out on its own. Maybe these ECUs have to go through a large number of cycles before there is somekind of internal reset...? Think I'll get one of those Carchips that RoverX mentioned.

Adam I believe I can help you.

First off the pump that was replaced is supposed to replaced for free under recall. LR understands the pump will blow when its rusted up.

Go to LR and get your money back. Seriously. They screwed you.

I did one last week that took me four hours. Every bolt broke and two hoses and the fuel pump all broke. It was all warranteed.. Manhatten was screwing you. Trust me.

And also about the four o2 sensors. Go to that shop and get your money back or threaten to take them to the bbb. Its your right. They screwed you. Demand your money back or better yet they pay for the damage they caused.

oh and we have had problems with the dealers in Manhatten and Paramus as well.

Scott's a good friend of mine. He really is a rare find....The true Honest mechanic. Highly recommended

Hello again and time to beat a dead horse with a stick.

A quick go-around: I was replacing an oxygen sensor at an non-LR repair shop and when it was replaced, all my oxygen sensors went dead. They are all new.

Between the time of the last posts and now (about mid-March 2006), I was able to get some second-hand ECUs for the D1, all from eBay and nowhere near one price of $2500. (Addeum: One outfit actually sent me a dead unit and then stated that I did not know what I was doing. Only after I wrote extensively with no replies, did I contact Paypal, who promptly returned the money after I forwarded them all the emails.)

When I swapped out the old ECU for the replacement, the D1 started without problems. Installed my ACTRON OBD2 codereader and the oxygen sensors were working. Had access to an Autologic reader and before the swap thought the computer thought the car was pre-1995 with no sensors. It hung on the cat convertor diagnostic.

After the swap, the Autologic reader saw the sensors and completed the cat convertor diagnostic. The car drove as if it lost several hundred pounds.Got to try one of the ECUs I bought and the car ran fine until I parked it some 9 miles away. Then I turned off the car and tried to restart it. The car Check Light would not turn on and the car would crank but not start. I Had to be rescued and then put the old ECU back in.

Looks like someone messing with the old ECU blew something inside of my old ECU. Now, I have two strategies to think about here:

I have three ECUs. One is damaged and not reading the oxygen sensors.

I also have another ECU from 1998 or 1999 which I have not had the time to try out.

I could spend some time trying to find which ECU would work. I could also just send out the old ECU and have it repaired.

Anyone else have had this expierence?

How do I reset the replacement ECU so I can keep it for my truck? It almost sounds like copy protection, except the truck is ten years old.

Nothing quite like having a 30 hour day either. I woke up early to get this resolved to then get stranded for three hours to then go do my night shift until 6 am then to go back home and recharge my old bones.

Huh.

Adam - have a look at this UK site: www.carelect.demon.co.uk/index.html
They say they only need 2 days to repair your original ecu, but how long it would take for shipping is another question. They show Range Rover but do not list Discos. I have no experience whatsoever with these guys. All the best.

From the US, you would have to add a week each way. There are plenty of ECU repair guys out there in the United States (my locale) . Just Google them.

I have a local guy who can send it out as soon as I can one of the others to cooperate. I wish I had access to a Rovacomm rather than a Autologic.

I also have to figure it out to properly do a ECU swap without getting stranded.

I have two more ECUs (one Discovery 1, and 1 Range Rover).
