Thread: Show us your ECU faults

None.

The only engine ECU codes I've had were due to the previous LPG installer's wiring the car without injector emulators. Since I rewired that section of the car, those faults have been cleared and not returned.

P0135
and
P0155

on a 99 Discovery Series II V8 auto
using a Scangauge II OBDII scanner

Caused by brand new aftermarket O2 sensors fitted by an independent LR workshop.

Going to get them to replace these dodgy O2 sensors with LR genuine ones, albeit at $255 each!

Thanks Tempest
Wanting to keep this an "ELECTRONIC LANDY" database.
Your input is appreciated!!!

ecu- topside switch failed pre injection/ingition,

car lost power an then shutdown---- would not start agen, after a wiel i got it started, it would idle fine but if it went over 2500rpm it would intently shutdown, or if you drove it an keped it under 2500 it was fine lik normal for about 1k an then shutdown,

fix-- new ECU,

this is about the worse fault code to get, if you get this its going to get expencive,

other things you will see are open circit on all 5 injectors, , this is all so saying ur ecu is buggerd,

topside switch is 99.99999999% the ECU is buggerd,

hope this helps some one, cos i was asking everywere for info about it an no one had eny, so this is a good start,

ecu- topside switch failed pre injection/ignition,
Would not start, turned over freely, but no start
got this error,then noticed the temperature guage was showing in the red
so naturally would not start!!!, then started, ran ok, then oil warning light came on, idel became rough, then oil light went out, normal idle.
stared next two times, then would not start again, started, then rough idle again and so on
Saw on a forum, clean your earth wireconnection where it joins the chassis and run another earth wire to a seperate part of the chassis, no problems for three months!!!

Yes I Was lucky but I had ordered another ECU because we thought the first was toast so now have a reflashable one that my friend mapped for me and it drives so much better than the old one Cost 250 british pounds, best insurance for that price so now have a spare(which has been used in another TD5 since and worked OK
