    Hey Chooch,

    Are you up for soldering the new ones on the PCB?

    lol I hope so, so far, I've managed to fix the PCB on the boiler at home, and done a few other bits and bobs, been soldering since I've been a kid, so this should be a doddle! But then again too much confidence can be a bad thing! I think I just need to make a trip up to Maplins to get hold of some non-tin based solder... Will let you know how I get on, when it comes around to doing it!

    Hats off to you Chooch, you're a braver man than me, good luck with the fix

    BTW if you take some photos maybe you could post up a "How To" guide so as other forum members could also benefit from your experience?

    Hey guys, just to let you know, I've installed the relays.............. and they work perfectly!

    One thing I would mention though, it's not as easy as it first looks. Taking the GM5 module out and taking the PCB out of the case was simple enough, but removing the solder from the relays is another thing! especially to the average Joe. The hardest part is trying to free the relays without damaging the holes for the joints, or the PCB.

    You need plenty of patience, a steady hand, also you need a soldering iron which heats up to around 500⁰C. Then you also need something to help you desolder the joints, such as a desoldering pump. also its a wise move to purchase a soldering aid kit. I would highly recommend purchasing a conductive pen, for when you're putting the solder back on the joints. Oh yeah, and I used silver solder for the joints. All in all the cost of putting this kit together was just short of £100. In total its cost me roughly £125 to sort this out myself. It would have cost me considerably less if my gas powered old soldering iron reached those temperatures. Oh well, I just gained another toy!

    So if you don't have any of these tools, I would suggest you find a "friend" who has all of the above, or an automotive electrician! I would have made a step by step guide, but the amount of time I took doing those relays was the only issue , as half way through the process I realised that my old soldering iron wasn't up to the job, and I had to go shopping at Maplins for the new one , plus the damn camera battery decided it would die.

    On saying that, Scott Johnson's website http://www.bmwgm5.com/ should definitely be looked over with patience. He has everything from; how to locate and remove the GM5 module, to what a bad removal of the relays look like. Take your time following his guides and you shouldn't have a problem. It's not as scary as first thought, but If anyone does get stuck I'll be more than happy to give you tips on how to DIY!

    I have the same problem on my 2001 330d, the problem may be the hazard/CL switch in the centre console. I disconnected it and the central locking is now working perfectly, you can get new switches for about a tenner and it isnt hard to replace. hope this helps!!
