#1: Problems after BSI and ECU transplant Author: Rob2859, Location: HalifaxPosted: Tue Jul 26, 2011 9:07 am ---- Firstly I will explain why I did this and show you some short clips of my car having a fit mostly for entertainment value.
Car running on 2 cylinders (fixed via mending a wire for the o2 sensor but that shouldn't have caused that anyway)
Overfueling
A number of unexplainable ECU errors
Wipers broken
Car having seizures (see videos)
Headlight coming on whenever they want
Electric windows not working
The electric windows and central locking still do not work so that is another issue.
The Airbag, stop and brake light are on all the time which did not happen before. Why are these on?
#2: Re: Problems after BSI and ECU transplant Author: Abzynthe, Posted: Tue Jul 26, 2011 9:08 am ---- The ECU might still have codes on them from when it was in the last car?
Just a guess, I dont really understand how it works lol
#3: Re: Problems after BSI and ECU transplant Author: Rob2859, Location: HalifaxPosted: Tue Jul 26, 2011 9:14 am ---- Nah as the ELM light would be on. Those lights never store a fault on the ECU
#4: Re: Problems after BSI and ECU transplant Author: Abzynthe, Posted: Tue Jul 26, 2011 9:17 am ---- ah ok then

EFA
Can't watch videos here but I'll have a look later.

Windows, have you checked to see if there is voltage going to the switches?
You made sure the airbag and ABS ECU are plugged back in?
Did you get the right ECU and BSI from the same types of car?
#7: Re: Problems after BSI and ECU transplant Author: Rob2859, Location: HalifaxPosted: Tue Jul 26, 2011 10:34 am ---- Lets forget the windows for now.
ECU and BSI are identical, everything is plugged in.
I have just found that I am still having original problems. The lights come on when the key is out and the cluster is flashing everything at me as it was doing before.
It has just decided not to start; I went to put my good battery back on and its doing what the videos show and that's it. Before changing the battery has solved this but its not any more. non-started once again.
#8: Re: Problems after BSI and ECU transplant Author: Lee, Location: EnglandPosted: Tue Jul 26, 2011 10:37 am ---- Does it have autolights?
Are all connections clean and secure?
Have you looked at the COM to see if that is faulty? [if you mux]
#9: Re: Problems after BSI and ECU transplant Author: Rob2859, Location: HalifaxPosted: Tue Jul 26, 2011 10:48 am ---- No autolights, they come on without the sidelights as well.
Plugs were all clean and a made sure they were seated properly. However it did this in the morning as well before I swapped everything over and on one occasion a while ago.
How can tell if the COM unit is faulty by inspecting it? Could that be the cause of the dial issue?
I tested the battery earth too it seems fine.
#10: Re: Problems after BSI and ECU transplant Author: Lee, Location: EnglandPosted: Tue Jul 26, 2011 10:58 am ---- Defiantly a loose wire somewhere mate. Check all the wires and connections.
#11: Re: Problems after BSI and ECU transplant Author: Rob2859, Location: HalifaxPosted: Tue Jul 26, 2011 11:06 am ---- I will start looking at the wires. Any ideas on which ones I should check?
#12: Re: Problems after BSI and ECU transplant Author: Lee, Location: EnglandPosted: Tue Jul 26, 2011 11:12 am ---- Start looking at the connector blocks on the BSI to the dashboard [cluster]
Dodgey communication. If you have a haynes, you want the canbus wires.
#13: Re: Problems after BSI and ECU transplant Author: Rob2859, Location: HalifaxPosted: Tue Jul 26, 2011 11:59 am ---- Double checked the plugs. Took the cluster out and its still making erratic beeping. I tried gentle tugging etc on that and the block plugs.
I do have a haynes but I can't find it.
The power cuts out on second ignition but there is power (lights flashing, beeping and relays clicking) when its off and the key is out.
I unplugged the plugs one at a time ether side of the comms unit but nothing changed. I have a spare ignition barrel that came with the ecu I am going to try that.
#14: Re: Problems after BSI and ECU transplant Author: Rob2859, Location: HalifaxPosted: Tue Jul 26, 2011 12:56 pm ---- Again that didn't do anything. Also it seems I have no power to anything else; the interior light, 12v plug and MFD do not work.
However I introduced a third battery (unfortunately its crap) and the headlights came on and so did all the cluster lights when I put the positive on. However it went onto ignition fine and it started.
Changing the battery seems to solve the problem but sometimes the old battery's work sometimes they don't.
Whats going on?
#15: Re: Problems after BSI and ECU transplant Author: Lee, Location: EnglandPosted: Tue Jul 26, 2011 1:00 pm ---- Still think there is a loose wire somewhere
Try checking
Black 10 pin connector on BSI. Pin 8 & 10
