Today the new XYZ switch installed. The old opened this was cork-dry. However, the pickup slider was a bit black, maybe burned and leaned a little back so that it did not hit the other side of the switch. In touch, this contact crumbled. This was clearly the problem. Unrepairable.

Thanks to all for your guidance and ideas. I could not resist to wait until the weekend and have check out the harnass and also the xyz switch under the car. I have concluded it is not a wiring problem but a water ingress problem. This is 99% conclusion based on the fact that the park/Neutral...

The M&S are not on. the last i tried this evening was removing the cover on the gear selector switch (center console), wiggled this around and than i could start the engine 3 times before it did nit again tried this once more and it worked again after this no luck. so will have to look there as...

I have the suspicion that the xyz switch is not 100% oke. It is an automatic gearbox td5 disco 2. The engine will not start due to the BCU relay not closing the starter circuit. i have checked al kind of wires and even changed the bcu. no improvement. however when i take of the cover from the...

Settings all seem to be correct. checked twice. All self test lights work no issue there. What i do know is that 4 weeks ago i had this issue 1 per week and it got progressifly and no it does not start with-out shorting pin 5 on the BCU to ground. I need to find somebody that knows the interlock...

Another lione of attack. I checked the BCU input sections for Body 1 and Body 2 and also the Engine ECU for Park Neutral positions Is it correct for the Body 1 to have the P/N constant on off where in Body 2 and on the ECU it is clearly detected when shifting the gearlever. I checked this as 2...

Oke so swapt the BCU, Set the ECU to learn code mode, waited 15 seconds etc. looked at the security state and it stated NOT IMmobelized. So i expect it to turn over. Nothing yet. I copied all the code from my old ECU to the new, went oke. MAde sure i entered the right keycode and connected the...

Oke, Thanks, A have a spare BCU form a car that is from the same year, software level is the same so should work. I will swap it ans ee if it start after learning and then do all the other bits of settign it up key's and all. I do have to find the EKA procedure as i have not looked at that yet.

Sorry for the spelling, small keys on my Phone.

I am learning al kinds of English her, what is fubar? Where do I find the Enigen ECU Utility - I expect under Engine ECU and then Utility. is it stratight forward? I have downloaded my old ECU setting soem time ago as a prepacution so i have an older file. I know all my key code so no issue...

So new morning new possebilities. I checked continuatie from the fuse 23 (ignition signal) to the fuse-box in the enigen bay, it shows 12 volt when key is turned. Then checked the other relais contact to pin number 5 of the BCU connector C0662-5 and when turning the key there was 12 volt on pin...

Thx found the connector, I have the rave. Yes I also hav a Nanocom evolution so I can enter the BCU. By programming you mean setting all the settings as in my existing BCU and programming the key code that are in the existing BCU in the new BCU and following the key sync procedure or is there...

Good thing is i have a replacement BCU if push comes to shuf.

Thx. I will check later in the week when it is not raining. Firts check c0662-5 when connected to earth and than start. I will also check continuety between this point and the fusebox in th enginebay. I need to find the C0573 connector wire 5 and 7. Thanks again for the help, hope I can return a...

Does the red white from the fusebox passenger compartment connect to 85 or 86. Also for the black orange from the bcu does it connect to 86 or 85 just to check continuety of these wires. Do i check 85 and 86 to earth when i turn the ignition switch?

So i check 85 to ground and then turn the switch and do the same for 86 correct? Shall i also check continuety between the BCU ands the relay contact which connects to the bcu 85 or 86. Also the red white from the passenger fuse box does it connect to 85 or 86?

Good we are on the right track then. If you mean by rave the electronic diagrams and connector details and all the other manuals, yes I do have a lot of manuals

I somehow get the idea that the earthpath from the relay is not made back to the BCU, or the signal form the passenger compartment fuse box does not connect to the fuseboc in the enginebay.. The BCU relay shows 11.9 volt when reading with my nanaocom Am I close or barking up a wrong tree?

U are a Hero! I have connected 30 and 87 and the starter fires. When I put the ignition in position 2 and brigde theese terminal the engine starts and keeps on running. When I turn the ignition key to postion crank the white-red cable shows 12 volt, fuse 23 shows 12 volt on both sides so in the...

I have a folow-up question. The starter has been overhauled the contacts were errode signle side to just under 1/5 a mm. so that is fine now. The engine still does not want to start. What do you mean by " the perpendicular cavities in the fusebox" it must be my english which pins of the relay do...
