Update for anyone finding themselves in the same situation. I ordered a replacement door lock part number 3B2837015A which works fine, It is not the same as the 3B2837015AP; the difference as far as I can see is there is no red parts as outlined in the attached photo. These may be some kind of manual workaround to unlock the door - you can push the top bit of the red parts (the lowest point in the photo) by poking something through a hole in the side of the door (the highest of the smaller, grommetted holes). I can do without that (hopefully). The mounting points are the same, the shape appears to be the same (fits fine) and the door locks and unlocks and opens from both sides fine. Thanks again to WIno for his time and input

Even if I have to pay to return it it's worth a punt. And can always give the beakers a go. The front mech is now doing the same as the rear did - won't open from the outside. Opens from the inside. The cable from the handle to the unit is connected OK

Thanks Wino. I think I am going to have to ignore the eBay sellers' answers that their locks will not fit and take a risk on one. They really do all look the same as the faulty part and I can't imagine VAG bothering with loads of different designs

Agreed UrbanPanzer, but when I ask them to confirm (as I have had problems buying the correct door mech for the rear door) I am buying the correct part they have all (6 so far) replied that theirs will not fit my car and they cannot supply one that does

Hi I need a replacement door lock mechanism for my Fabia and am having trouble sourcing a cheap aftermarket unit. I won’t pay Skoda prices, will go to scrappy if needs be. All the eBay sellers tell me they can’t source a cheapy (about 20 quid). My question is: how unique are these units? Aren't they fairly interchangeable across the VAG? Surely other units / part numbers are useable? My faulty door mech is part number 3B2837015AP. I have attached some photos Vehicle details: Dec 2007 Skoda Fabia mark 2 1.6 petrol hatchback manual right hand drive BTS engine There was a shape change in 2007 and my car is the newer of the shapes - 2007 to 2014ish, the 5J shape / model I believe. I have replaced the rear passenger door lock mech in the past and found that a mark 2 unit did not fit, and that the one that did was listed (cheapy on eBay) as a mark 1 unit. That is still going strong. Thanks for your time

Thanks Robjon

Pretty sure it got the original battery. I got the car at 36000 miles, was only a few years old, unlikey it been changed. Will have a look for that part number, got multimeter at the ready.

Ah, another excellent idea, thanks. Battery has never been changed and ambient temperatures now low, so that's one to check out

Again, many thanks for your time and expertise, it is greatly appreciated. I will admit to experiencing signs (websites offering many ECU types) that not everything was dealt with by the ECU I referred to, I think there may have been a certain amount of "I hope I can just change that, get it programmed and happy days" going on in my head. It comes as no surprise that it not that easy ha ha. I have been on Briskoda before, many years ago. Dunno why it says I am new, I have posted and received excellent assistance previously. Does highlight the fact that my Fabia has been amazingly reliable, I love it. I have had an Audi and a VW, and had far more problems with them (but then they were higher performance models and may have had a hard life). I use a cable and software that I bought off eBay to access error codes. Obviously not the full VCDS, but think it offers more functions that the freeware version. Will let me access most modules individually to download codes. I am not 100% confident it is fully operational however. I may try reinstalling it. I do have a friend with a code reader device as well. You have given me further avenues for investigation and ideas for rectification, I shall crack on with those. Car still works fine in the main, but would be nice to get the niggles sorted.

Thanks Wino, have checked some fuses and none were blown. Good to know about ECU reliability. I have read about A pillar problems and was about to investigate the wiring and door lock mech when the display starting playing up. I then thought there may be a wider problem, maybe with the main brain, which I thought was the ECU under the bonnet (near firewall). But that based on very little knowledge, as I am sure is evident. I have also had problems with engine warning light showing but no fault codes being recorded and no obvious faults, and low oil warning light when oil near max and new sensor installed. All suggested a major breakdown in software. Anyway, you given me somewhere to start, thanks for your time and consideration.

Hi. Having the following intermittent (everyone’s favourite) electrical problems: 1) Clock and trip mileage reset themselves; display switched itself from mileage-left-in-tank to outside temperature 2) Interior light doesn’t always come on when the driver’s door opened 3) Relocks itself, and alarm reactivates, despite drivers door being opened following door unlock using fob 4) Boot no longer opens along with doors (used to) I was thinking it may be the ECU degrading (I have a late 2007 Mark 2 1.6 petrol manual Fabia with 113000 miles) and have been investigating getting a replacement ECU (breakers) or having the ECU flashed. Anyone have any ideas before I proceed down that route? Thanks.
