Actually come to think of it. the alarm goes off when I unlock with the key. so I’m guessing no.

I see. I will double check connivence opening and closure is activated in BCM then. I’d imagine it is but just to be sure. Earth is fine. Interestingly though the power going to the motor had continuity with earth. So to me means it is shorting out.

So the car seems to be running fine. Won’t be able to get the MOT done until later on in the week so Il hang fire on the long drive till then. i fitted a wiper motor and linkage today I found on a 12 plate breaker in a local yard. Previous one had worn out and failed. I’ve checked over the underneath whilst it was on the ramp today and all looks well. The two failures on the MOT have been rectified so should sail through. Electric windows however 🤯 Today I removed the drivers door card. Unplugged the loom from the A pillar and removed it from the car. Had a little nosey at the wiring and it looks like it has the same problem every other Roomster has. Broken wires in the harness. So I’ve repaired the best I could and still not getting anything at the switch. I checked the pins on in the A pillar and one was a bit green so I’ve rectified that. Interestingly the convenience closure with the key in the door and holding the fob does not lower the windows. Fuse 11,51 and 52 are all ok. I will try some further testing in the morning. I had a little look on VCDS the other day to see if the window module shows in however I couldn’t find it.

Yes the torsion value can be difficult to get. I find some are pains some are fine. Vw more than likely have a tool in house that allows this to be set a lot easier. what I find a pain is that VCDS doesn’t always name it as torsion value. Sometimes doesn’t even show it.

Price for a new one is nuts il be sourcing a replacement from a breaker. I’ve shut shop and packed in for today will resume over the weekend. I’ve spent 12hours a day the last 3 days in a freezing cold garage with nothing but a can of red bull and a bag of haribo. All for the sake of a blade fuse 🤮. On the plus side. Cost me £68 for crank and cam sensors. thank you for your assistance your knowledge and access to diagrams etc is massively appreciated. i shal update this thread in due course.

Torsion value corrected now starts on the button It’s a little Smokey black out the back Wonder if the cat is blocked following a period of running like this. might just need a spirited drive. going to call it a day now. and order the correct vacuum box

So……. struggles to start still I get camshaft implausible signal P0341 however all codes relating to egr etc are staying off. will need to test drive yet. il check torsion values for the camshaft code camshaft sensor was replaced yesterday. My front windows don’t work I wonder if someone has been on a fuse spree …….. appreciate the wealth of knowledge Pete

Slot 28 the fuse is missing il put this back together and test it

6 pin connector on harness: vac continuity from plug to ecu plug Pin 1 - BLANK Pin 2 - BLANK Pin 3 - blue and black wire- doesn’t appear at ECU Pin 4 - blue and black wire - doesn’t appear at ECU Pin 5 - purple and white has continuity Pin 6 - brown and white has continuity 4 pin connector EGR. Pin 1 - Brown 0v has continuity to earth Pin 2 - blue and black 0v doesn’t appear at ecu Pin 3 - red and blue wire- has continuity Pin 4 - red and violet wire- has continuity where do the blue and black wires goes. ?

Further testing on the G28 harness 3 pin plug. With ignition on Pin 1 - White 4.5v Pin 2 - Brown 4.5v Pin 3 - black 0v has continuity with earth.

Thank you Pete il send you the vin my vehicle when purchase was fitted with vacuum box number 6Q0906625C I have now damaged this beyond use attempting to see if it was the fault. After observing rust on the mesh to a port. I tried 6Q0906625 (no letter on the box) was 6 pin golf. I tried 6Q0906625A removed from a 2005 polo 1.4 TDi. Plug was different however was from a 4 pin car. I still need to find a C one to replace my C. The V157 wiring connector appears to be fine. I attempted to perform a function test earlier in VCDS however wasn’t moving nothing. im testing all earths and seems to be fine however the below is the voltage when ignition is on. 6 pin connector on harness: vac Pin 1 - BLANK Pin 2 - BLANK Pin 3 - blue and black wire 0v Pin 4 - blue and black wire 0v Pin 5 - purple and white 1.3v Pin 6 - brown and white 0v 4 pin connector EGR. Pin 1 - Brown 0v has continuity to earth Pin 2 - blue and black 0v Pin 3 - red and blue wire 0v Pin 4 - red and violet wire 4v

Hello I’ve browsed the forum for a while for Vag related issues however I’ve owned 16 Vag cars in last 10 years I’ve never owned a Skoda. Nor have I ever been faced with this issue. I’m convinced this is an electrical problem but thought I would put it out there. I have purchased a Skoda Roomster Scout 1.9Tdi BSW code. I purchased it spares repairs for what I thought was a tidy fee. The car takes a little while to turn over but fires up. Runs smooth drives flat. I’ve attached my VCDS scan. Glow plug light flashing EML illuminated. Runs in limp mode. I think this is electrical fault on the basis the codes will not clear. Even if cleared and engine not started codes shown appear on the log immediately. Irrespective if engine is started or not if codes are cleared they return. The codes are circuit specific codes so this backs my theory up. Since the issue: New battery Egr, anti shudder and intake cleaned of all carbon. (2cm thick of supermarket sludge) Turbo actuator tested holds vacuum Turbo has almost no play Intercooler flushed All boost pipes cleaned out. The vacuum pipe from servo was split this was changed out for another unsplit. New crankshaft sensor New camshaft sensor Torsion value checked and in tolerance Vacuum box replaced Earth points checked and rebrushed where required. All fuses checked in cabin and on battery. Car has had a new starter motor in the last 6 months. Car still starts and runs however in limp mode and lights flashing I’m now at the point I’m checking all the wiring for breaks and corrosion however have not found anything. One thing I will add is that I have picked up the wrong vacuum box. I picked up a mk5 golf one from the breakers so this could be an issue. Patiently waiting for Breezy_Pete to shower me with knowledge.
