Is there any point in getting one if you already have a Gen3? Not that I've checked yet, just curious :)
Nope - If you've got a Gen3 receiver then the filter won't do anything extra for you.
To clarify a bit of the door latch situation - yes they are listed on my website that I don't do them anymore. This is mostly because I have pretty much run out of some of the parts to build them - mostly the Central Locking motors which are known to burn out on earlier vehicles at times. Between that and people not returning their old latches once I'd send a refurb one out has left me low on stock.
I do have about 6 of them that have trickled back in, but most of these are LH latches, with only a couple of RH ones - and at least one of these already has someone after it.
I will still do door latches - but they won't be listed up on the website again until I have a decent stock of them which are refurbed and ready to send. Also part of my lack of enthusiasm towards them is that it is a pretty laborious process to rebuild them, and given that I try to make them affordable vs second hand units and the fact that I'm most likely not going to get units back honestly means I can't be bothered a lot of the time! Especially as I've been away working a lot more this year - to then spend a large chunk of the little time I've had at home pulling manky old latches apart isn't really my idea of fun! As/when I get time and inclination I will obviously continue to process the ones I have - but as such not advertising them anymore.
I've scaled back a lot of what I'm doing now, most around the fact I've been busier with work - but also that I have my own things I want to do when I am at home. I've also had a few cases where people seem to take the piss a bit when it comes to my knowledge/expertise. I had one customer who I'd fixed an ABS ECU for him back at the beginning of the year email me to ask about the warranty on it (which is stated at one month - but I'll obviously try and help out prior customers as much as I can) - because he suspected it was faulty again - but with a DIFFERENT fault to the one I claim to fix, and had actually repaired on his ECU. Because I was about to head away for work, I said I would send him a spare ECU I had that was tested, so he could try it and let me know if it made any difference - as it would be quicker all round than him waiting for me to be back home and then sending his ECU back to me for testing etc. I told him to let me know the outcome, and if the replacement ECU fixed it, to send the faulty one to me so I could check and see what the issue was etc. To this day I haven't even received a message to say the other one arrived (it did as I checked RM website), nor whether it fixed the problem, even a thank you for sorting something out - which technically wasn't even in warranty, but I did to try and help someone out. I chased the customer up a couple of weeks ago with an email (as it had been over a month by this point) and still haven't had any form of response. So that's £100 worth of ECU/postage which I won't see again, because I'm trying to do the right thing by a customer, who if they'd originally paid more for a replacement ECU from a breaker would have been told to go buy another one...
Between things like that and not getting core items returned (yes I keep the core charge, but that doesn't actually cover buying a load more faulty parts to then strip/rebuild) and being busier with work, means that I'm a lot less inclined to bother with a lot of parts these days. I know it's a case of a few people ruining it for everyone - but unfortunately when you're doing it for yourself and it's not a main business, then things have to be prioritised..
Another example before my rant is over... I tested a BECM for a customer as his local Land Rover expert had traced an ABS fault to the BECM. He brought the BECM and ABS ECU to me for testing (I was under the assumption the vehicle wasn't driveable long distance because of said ABS fault, but found out later the whole vehicle could have come to me which in hindsight would have saved a lot of headache). I tested the BECM and ABS ECU on the bench, and found nothing wrong with them - I tried a second BECM with the ABS ECU to check if it reacted the same, and after a few hours, found that they did both work as I would expect for a bench test, and I found nothing wrong. "What do I owe you" I was asked... "Don't worry about it" I said, "You've driven 3 hours to bring it to me and have a drive back now - and in reality I've only spent a couple of hours going over things on the bench, and I haven't even fixed anything as to me it looks fine". A few weeks later I'm then getting emails and calls to say that the BECM has now been refitted and the vehicle doesn't start at all, and can I call the Land Rover expert to help him figure out why. I tried calling, to get it ringing out, not even to an answerphone. I'm then away for work for a few weeks, and get a call whilst I'm in Canada at what's 4am here with the time difference. I woke up and missed the call and had a voicemail which came across as being a bit peeved off that I hadn't contacted HIS Land Rover expert to try and help fix his vehicle. I ended up calling back and then a few phone calls and a couple of days later get in touch with the garage to find that it isn't turning over (GEMS petrol) but the Check Engine light is on, but the engine ECU says it has "incorrect settings" when he tries to get it to relearn a security code, but yet can read that there are no faults, and see live data?!? And that he hasn't done any other form of troubleshooting as he's been waiting to hear from me (though never tried contacting me directly either). After going through a few things to check over the phone, he said he's try them and then if I called back when I was home he would update me... I got an email a couple of days later from the owner saying it hadn't started from the key but by jumping the start relay it started... so the BECM isn't outputting to the starter relay, or there's an issue with the wiring between BECM and starter... so I've spent another hour or so compiling information, connectors, wiring colours etc from RAVE for the expert (who's actually being paid to fix this) to check. I know that it will still ultimately end up being "my" issue to solve when I get home if it isn't already sorted... but all this now because I did something for nothing in testing the BECM, when even before then I was fairly confident it wasn't a BECM issue - though I was assured the fault had to be there as it had been traced to it.
Rant over - but I just thought I would share a bit of some of the things which seem expected of me trying to help out - on top of working a full-time job! - I don't mind it most of the time - but sometimes when things aren't sent back, I'm expected to solve issues or give ideas/information freely where 'experts' are being paid to fix these things - or people taking my generosity of trying to get an issue sorted and work the details/financials out later to the point of not even returning emails now... some days it makes me wonder why I bother!
Definite rant over.... but if you are still requiring a door latch when I get home... I might just have one in pieces ready for reassembly, that I am aiming to get sorted after I've kicked the jet lag. If you have already sorted a replacement and feel like donating the dead one to the 'cause' then I'll happily pay for the postage!
