problem now solved .. i feel such an idiot . but i cant remember touching that fuse for the roof never mind putting it in the wrong slot . i think someone is playing silly games with me .

window calibration didn't help . have been trying all day to dry it out inside after punching holes in the rubber plugs in the floor . it was at least 3 inches deep under the carpet . next up is get a wiring diagram for the roof modules and see if i can see activity on the can lines and see if it has the correct power to it . o only have bench scopes but should do it . if all looks right there its time to chance another module and see if it appears on the gateway . on the plus side i took it for retest so its got an mot now . i think the battery is ok it looks brand new . and its not showing as a fault with vcds . it got a bit low because i had the ignition on a long time when working on it .

battery is least of my problems right now . i can use a charger for now for diagnosing . what i cant understand is why when i query the passenger door module it gives me code 00830 no comms with roof module . i had to code in the door module to get the mirror and indicator in the mirror working . its since this time the boot stopped working and screen heater and the roof . it suggests to me a break in comms that goes through the door module . oh i cant see how to change to B in coding . no idea if needed or even possible . maybe i simply need to calibrate the window ? cant do this until new mech is fitted . the door module is an earlier one suffix B instead of D . i have had the door unplugged from a pillar just before i coded new module in .it was left overnight with lots of rain getting in the car but it was plenty wet inside before . i can unlock the boot with vcds .

it measures the voltage .if it goes below 11v i will know how good or bad it is . to measure that sort of current i would need a massive resistor so i could measure volts across it and calculate the current .

might use my battery tester unit . or just my multi-meter . i can check volt drop when cranking . either way it will tell me if its bad or not

it was working fine before changing the door module and coding it in . have tried with engine running for ages then clearing codes . i wasn't getting the comms fault before so suspecting wires or roof module . tried the old door module back in and still same issues . all these things not working also lead me to the roof because its behaving as if the roof is down . no dash warning of that though . i will next fit the new window mech and calibrate the window just to rule that out . i will have it here tomorrow . i can test the battery myself and the charging .

ok replying to myself again error code found in passenger door module .. 00830 no signal/comms convertible top module j256. am guessing its a bad can wire or the roof module at fault .

looking at this some more 2 things stand out .one is the low voltage and the other the roof being as that can affect all the faults i need to fix . i will scan the roof module and look into it some more

my first post here so go gentle with me . ok here we go first thing was the passenger door wouldn't unlock plus mirror electrics not working . sorted that with replacement door module and had to code it in . that is all good and working now . now the boot lid wont unlock with the fob and the boot switch on the boot . but unlocks with the key and also with vcds making me think the wires are ok . i fixed the reverse light when fixing the bad wires in the rubber tube at the boot lid . the boot lock worked fine before also the rear screen heater stopped working it lights the switch for 2 seconds then off . interior lights also not working with the door . i can do a full scan and post it here if it helps . here are the codes in red
