Hi all. Been looking on various sites and of course YouTube as to change my transmission fluid on my e92. 

Seems to be a different train of thought as to keep the fluid as is( BMW advise this apparently) and most youtubers advise to change! 

So here I am asking the ones in the know should I go ahead and change it? Ive had the car for nearly 6 months and all the history and receipts Ive got show no record of it being done. It's just ticked over a 100k and still drives perfectly,touch wood!  Oh and one other gripe I have with it is the braking performance, I'm getting a slight wobble on steering wheel as I brake and again looking at its history it's had pads an discs renewed and to the naked eye the discs looked good. Is there any other issue to consider? Thanks in advance team 👍

I have personally never heard of anyone advising to keep automatic transmission fluid 'as is'....it is supposed to be replaced periodically, and would certainly benefit the transmission to do so. You should also replace any filters and gaskets that you encounter when replacing the fluid. The only thing I can imagine is that like Mercedes, you would have to drain and refill an exact amount of fluid and/or obtain a dipstick if there is not one present.

The braking matter....more than probable that it is warped discs but these can easily be measured for run-out by any reputable garage.

Hi Trevor. Yes I do agree with regarding changing the fluid seems to me an important part of care for car. Will organise just for peace of mind and if any member can refer me to a reputable specialist up here in freezing Scotland I would be grateful. As for the braking issue have you ever heard of new pads being "cooked" before proper running in period? I myself tend to thinks new discs would solve the problem. Cheers 

I think cheap brake pads have a tendency to 'cook' quite easily.

I recently replaced some 'brand new' Apec pads on the rear of my Honda CRV as they were crumbling slightly like they had been overheated. Replaced them with quality pads, so if you are going for new discs and you see the pads are something cheap and nasty then replace them with quality branded pads...you will notice the difference.

Yep I think that's the most prudent course of action Trevor. The last service on car was a BMW specialist and the previous one was by Arnold Clar, the rest was bmw. So good chance the cheap pads went on. I'll say to my guy when changing to check them out.
