Today I have replaced the gearbox and diferential oils. My car is a 6 speed manual 30iSDrive with 63k miles. The tech said that the differential oil's colour was ok but the gear box's was quite dark already. The difference is so noticeable: less noisy operation and the gear changes are much...

Thanks for the reply. I had seen that on eBay and for a while I was considering it as an option. However, I enjoyed learning how to do it by myself. Now that I know how it's done, if I need to do it again I'll be able to do it much quicker and for much less, since I have all the tools and...

My car came with two key fobs. The one I have always been using and a spare one, which looked brand new (it had the BMW stamp at the back). With it, once I gained access to the car with the good keyfob, I could start the car but could not lock/unlock it. Owners of E89's with comfort access can...

In the end I bought the oil and it's actually SP spec, not SN+. I might have either misread or read the wrong oil 's specs, as I had many tabs opened in my browser at the same time while doing the research. Luckily I also got a Bluelight discount so I got 7 LTRs for £70 which is not too bad, I...

Thanks for the reply. Indeed, both my user manual and oil filler cap have a reference to Castrol oils. It's a shame that the user manual's references to fluids are either non-existent or very vague, compared to other car brands. I think that I'll get it tomorrow. The car has done around 4k+...

As per the post's subject. Has anyone tried this oil (Edge 5w30 M)? BMW Longlife-04, ACEA C3, API SN PLUS. I have never used Castrol before. I have almost always used Shell Helix Ultra in most of the cars I have had but it's on offer now at Halfords and cheaper than at Autodoc and eBay. My car...

If we're talking about the same person, I believe he's an admin in the Facebook East Anglia BMW Z4 Owners Group, of which I am a member. I have only chatted with him once, very briefly, regarding a question about E89 roofs. He seems very friendly so certainly worth a message/call inthe future...

BMW LC-87 coolant is the (correct) one they've now used on mine. It's really annoying that in any other car I have had, I could find the coolant and other fluids' specs in the user's manual but nothing in the Z4's manual. Hope this post has helped you.

Thanks for the link! Yep, the one in Suffolk is the one I went to... Cambridgeshire is an option or even Norfolk. Worth a try, I guess.

I received confirmation this morning that they used the BMW's OEM coolant: LT Coolant 87 G84 spec. BMW part Number 83515A6CDD7 Well, it seems that now it's all good... But I have been left thinking that had I been a person with 0% knowledge of cars (most people) and with a black coolant...

I think exactly the same! I did not want to mix coolants inadvertently and reduce the corrosion-inhibiting properties of the coolant. I don't skimp on anything related to car maintenance and always use either OEM or with OEM specs. You told me in a previous post what the correct coolant spec...

In the end they flushed it again and they replaced the coolant. They assured me that it was G48 but I am getting paranoid paranoid and am thinking that they could have put G11, which is also blue... Is there any way of telling? Does it matter if I mix G11 with G48? At least the slimy residue...

Thanks for the info. I'm going to get the oil filter tool. I am just waiting to do a few more miles with the existing oil, which has only 3k miles on it. Around mid-July I am aiming to do the oil change, air and polen filters.

Thanks for the info! :)

I think it's mainly to flush the radiator.
