Door Solenoid burnt Door/Window ECU?
Discussion
the door opening did not work properly since a few weeks. most times i had to use the secret entry cable.
yesterday i thought : why not trying the passenger side and see what happens:
window lowered, door popped open...so all looked fine
but when i closed the passenger door it did not "lock" inside the latch.
latching it with a screw driver doesn't get it to "lock-position"
each time i pushed the release button on the mirror you could here relais clicking in the boot.
i opened the boot to give the Window/door ECU a reset by disconneting the power-connector.
unfotunately there was a burning smell comming out this ECU...one of the condensators has burnt.
the probem with the latch could be mechanical....but why the ECU burnt or lets ask differtn: why a mechancal and an electrical problem are happening in the same time?

my ecu is on the way back from repair....it was definately burnt (damaged). the repair-shop highligted that i MUST check the passenger side door-solenoid, as this looks to be resonsible for the burnt ECU.
TVR has not built-in any safety for the ECU , in case the solenoid goes on overload.

new door solednoid fittted (the old one was definately damaged), parallel to that i sent the ECU to a UK-Specialist for repair.
they said it has been tested after repair and was declared as "ok".
now with a new passenger -solenoid, a repaied and tested ECU i was quite optimisitc that i finally can enjoy the car, now.
but no....: when i connected the ECU the first time, nothing happened...ususually you here some clicking and the ECU checks the status of the doors etc. (at least it has done this before it was damaged)
but nothing.....the doors cannot be opened, the windows cannot be moved, even not manually from the buttons in the centre console.
when me and my mate stood in front of the car , headscratching and discussing what could be the cause or if we may have done something wrong, out of a sudden the ECU developped (just for a few seconds) a low frequency buzzing noise....also some clicking of the internal relais could be heard....but thats it....still nothing works.
i interuppted multiple time the power-supply to the ECU...just to see if it may re-initialize....but nothing changed.
i´m now totally lost. for me its sure that the doors/window ECU has still a defect....

look...the ECU worked reasosnably until a damaged door-solenoid burnt the ECU.
the solenoid was replaced and for safety reasons the ECU was only re-connected, without the new door solenoid electrically connected. only later the solenoid was connected as well.
means the ECU was connected to a car which status was considered to be ok before (door switches, window position switches etc.)
i know what you mean with testing all circuits, but why should i test everthing and suddently pressume that all parts might be faulty, when the orignal cause was "only" a faulty solenoid?
i mean if for every little elelctric-problem on the car, i need to test always the complete car, i will never come to an end.....
