That brake pad looks like a 'waffer thin mint' 
New brakes will be good Sam; you know I rate those pads highly
Yeah, fair to say they’d seen better days. God knows what they’d have looked like if I’d listened to the CBS. New brakes will be good Sam; you know I rate those pads highly
They’re great pads; I’ve been running them in the front for a few years (had them on the 125i and they’re on the 330i too). Definitely worth the extra to reduce brake dust.

Fair play for cracking on and sorting. Serious question. Having never done my own discs and pads, how easy is the job, talking as an utter amateur? Any special tools needed, does it involve much swearing, etc etc? Not that I'll need them doing for sometime mind. Got the guy refurbing the alloys to have a gander around them with wheels off, he said discs barely worn in, and about 8mm all round on the pads.
The fronts are a piece of cake, the rears can be a bit more of a sod if there is a deep groove from the handbrake shoes. Luckily my rear brakes had been removed on September when the rear bearings were done so it was dead easy. The ones on my wife’s old 1258 were sods and I had to fiddle with the adjusters which are a bit awkward to access through the wheel bolt holes. A piston wind back tool makes it a bit easier (mine was cheap from Amazon). Other than that it’s a 7mm Allen key and a socket set.

Cheers matey. I was recently wondering which thread I asked you that, as I couldn't remember where I asked. Next time I need the fronts doing I may well give it a stab.
No worries, fronts should be dead easy really.This is the piston wind back tool I bought

Been having a good read through this thread recently, so thanks for all the detailed updates, OP, I've really enjoyed following through the story so far.
I have an E89 with the N54, which has unfortunately just succumbed to the (inevitable?) injector failure, so while the prodigious bill for fitting a set of index 12s is in the offing, I'm strongly considering taking advantage of knowing that it's dealt with as an opportunity to turn the wick up a bit.
How did you get on with the Masata intercooler? It looks like a reasonable price compared to some, and seems like it'll fit the Z4 (though I don't think I can have the hardpipe upgrade you fitted at the same time).
And the P Torque tune, I know there was a hiccup you had with an engine light a little while after having it done, but IIRC that wasn't specific to the tuning at all? How have you found it overall? I like the idea of going to someone with a good reputation who will give me a very solid, reliable remap, I'm not interested in getting the biggest number, I want to have something I don't have to worry about, and to not push my luck with what the DCT gearbox in my car would be happy with (will be getting this serviced before I do anything, too).
Current "best" options I can see are P Torque, BW Chiptune, Evolve, and DMS, does that sound right? Anyone I should add/remove from that shortlist? P Torque wouldn't be at all bad for me as I'm in the midlands, but I've got no issue with a bit of a trek to have the work done by the right person.
It's not something I'll be doing immediately either way, partly because I want to get the injectors fixed before committing, (in case I'm told it also needs a HPFP or something to get it totally A1), but also I don't think my current insurers like remaps, so may be best to wait until renewal in a few months and see if I can get a sensible price elsewhere.
Also, when you went to 265 rears, you had a bit of rub, but I don't think your offset is standard, do you know what your rear ET is? I'm currently on some 18s with CrossClimate 2s while the weather was miserable, but come summer I was thinking of putting 265s on the 19s I got with the car, as the rears are 9.5 wide and the 255 looked a little narrow on that to my eyes, which I think was the same logic you had to your choice to up the width a hair. I know we're talking about different cars, but with my rear offset being ET35, I'm thinking it'll probably work ok.
Probably not going to get close to the level of regular detailing you manage on your E92, but I'll still try to make sure mine's tidy, it's been looked after pretty well by the previous owner, but I think more just kept washed rather than properly dug into.

A set of Index 12 injectors is a bag day out. I think the best I’ve seen is from a midlands based specialist who will supply, fit and code them for £2.7k. The impact of Covid on supply chains has really pushed the price up - I found an on ML Performance web page when they were £147 each - much more reasonable than £367 that they’re now charging.
The Masatta intercooler seems really good especially for the cash, it’s substantially bigger than the OE one but fits easily and it seems to do its job of keeping the intake temps down. With the stock intercooler, they rise very quickly. Is the N54 layout on the E89 a bit different to the other platforms, hence the metal charge pipe not fitting? I never experienced any issues with the stock plastic one despite the internet telling me that it’ll definitely split.
When my car last experienced limo mode (the day of the map and once driving back from North Wakes) it had a K&N panel filter fitted. I’ve since swapped back to a stock paper one and it’s been fine. For whatever reason, my engine really doesn’t like aftermarket filters. The dual cone intakes upset it, as dud the K&N.
I’d definitely recommend the map; it was a drive in a mapped E89 35i that convinced me. The difference in performance was really quite stark. In stock format, my 335i didn’t feel massively more powerful than a 330i (more torque for sure but not hugely faster). There is now a massive difference between my wife’s mapped 330i and this; I often forget because it’s largely driven quite sedately, it’s only when I’m in the mood to be silly that I realise that it’s actually quite a quick car.
All of the guys are in your list are well known and have a good reputation. I chose P Torque because he’s pretty local and I used him for mapping my wife’s old 125i as did two friends. We were all happy with those, so it seemed logical to go back to him. He uses a dyno to set the cars up too which was a selling point. I don’t think he pushes the bkundsroes too far - my car made 380bhp / 572nm of torque as a stage one plus (map plus intercooler). This seems quite conservative compared to some figures you see banded around (it was on the money for what he was expecting).
My rear wheels are ET27, which is pretty aggressive. They won’t fit the face lifted cars which has a slightly wider track. I agree that 255’s on a 9.5j wheel look too stretched.
Good luck getting it sorted.

If you have some time to spare here's a link to a 35is owners' build thread, although his final iteration is running over 500bhp! https://z4-forum.com/forum/viewtopic.php?t=131886 But he may be able to give you some feedback on your plans.I'd agree a 255 tyre looks stretched on an 9.5J rim. I had 265s on my CSL Reps and would have preferred wider still, but I sold them and went back to 18s.

Yes, I think I know the people you mean, the company I've gone with are a bit higher, but I was able to get the car limped over to them without the cost of transporting it etc, and it's genuine parts with a decent warranty fitted by someone with a positive reputation, so ah well.A set of Index 12 injectors is a bag day out.

It was going to be somewhat punchy on price no matter what, but I knew that was a risk buying an N54, so while I would have preferred to have got a bit further along my ownership before taking this hit, I have had the car long enough to know that I like it and want to sort it.
I'm capable of doing the job myself, but the thing is, with the parts being so expensive, it's proportionately not quite so painful to have someone else do the work, and the price they gave for doing the DCT service was reasonable, so there's that.

You know, I'm not sure on the layout, I just saw the pipe didn't seem to be listed for the E89. I may just ask them if it fits.Court_S said:

Aha, hopefully I'll be safe, then, I'm quite content/intending to keep the standard intake and filter.Court_S said:

That's quite a chunk of torque over standard! More than I thought a simple remap would kick out. I may need to take care over what my gearbox can cope with, I believe it's somewhere in the 500s Nm-wise.All of the guys are in your list are well known and have a good reputation.

Ah, yes, that is a bit of poke. The E89 is staggered for width and offset as standard, my factory 18s are 8.5" and ET40 at the back and 8" and ET29 up front, while the alloys the car came with are 9.5" rear and 8.5" front and ET35 both ends. It drove fine on them, runflats excepted (they are off and not going back on!), so I'm happy to keep them. Clearly just a relatively cheap set fitted to replace the cracked ones flagged up at the last MOT, and not the last word in lightness, but I quite like them, they're a gunmetal replica of the 789Ms that the F90 Comp has, only sized down to 19".Court_S said:
Good luck getting it sorted.
Thank you! I'm sure it'll all be right soon enough, albeit at a cost, but that's the deal with these cars/engines.I just tell myself I'm probably still coming out ahead of the smashing my wallet would've taken from the comedy option of a cheap DB9 which briefly crossed my mind!

Ah, thanks, I'll have a read of that.I have my Z4 back, and had a nice startup this morning with no misfire etc, so at least the thorough kicking my wallet has taken appears to have achieved the right result.
They misquoted the DCT service as a regular auto one, so I had to dig into my pockets a little further to cover that, but ah well! There is a slight weep from the side cover apparently, but dropping the box to rectify that would've doubled the already noticeable service cost (but still cheaper than BMW wanted), so that's been filed under "monitor for later".
Next challenge! Masata do make a chargepipe for the E89, yay!
But Masata also say their N54 intercooler won't fit the E89, boo!
This seems very odd given that the E9x 335i and E89 35i have identical part numbers according to Sytner,
but having asked them, it seems it's just they've never tried it in an E89.
I think what I may well do is order one as listed for the E90 335i, and see how I get on, I can't see any logical reason why it won't work if the original parts are identical.

Z4 doesn't need a charge pipe upgrade, they are bulletproof already. It was only the 335i that had a weak charge pipe. You can save a little cash on that.

The Masata intercooler will fit the Z4. My recommendation would be on a CSF intercooler though, they are an overall better bit of kit.

Good to hear the injectors have solved the issue. Sounds like your dead injectors were quite bad; mine was only slightly leaking so the car started fine, there was just a very slight pop when it idled.

The DCT is notorious for weeping slightly from what I can tell from my M3 research.
If the part numbers are the same, I don’t see why it wouldn’t fit. I’d be tempted to give a go as well.
No worries about posting on my thread.

Ah, good info, thanks, they're out of stock right now anyway, so I might swerve that for the time being, can always fit one later if it lets go.car user said:

They are, however, more than double the price!While I'm generally a firm proponent of the "buy cheap = buy twice" maxim, Court_S seems to have had success with his Masata unit, and like the CSF it's also a factory fit design rather than needing to change to hoses and clamps.
I think in this case I'm willing to take a punt on the Masata, I can always move it on if I feel it's not right.

It wasn't too bad initially, but went downhill significantly over the last few weeks. Apparently #6 was really terrible, but none of the others were particularly wonderful either.I've got the old index 9s, might send them off for testing/cleaning and see if any are considered still serviceable in case another owner just needs one of two to match the rest of a bank.
Court_S said:

Yes, it does seem to be a bit of a thing with them, I believe they usually replace the sump by default when servicing them thanks to their proclivity for slight incontinence, but I didn't think it was serious enough on my side cover to justify the expense.But I am an ancient Land Rover owner, so take my opinions on an oil leak not being serious with a pinch of salt. And possibly a bucket of something more absorbent.

If the part numbers are the same, I don’t see why it wouldn’t fit. I’d be tempted to give a go as well.

Z4 doesn't need a charge pipe upgrade, they are bulletproof already. It was only the 335i that had a weak charge pipe. You can save a little cash on that.
Ah, good info, thanks, they're out of stock right now anyway, so I might swerve that for the time being, can always fit one later if it lets go.car user said:
The Masata intercooler will fit the Z4. My recommendation would be on a CSF intercooler though, they are an overall better bit of kit.
They are, however, more than double the price!While I'm generally a firm proponent of the "buy cheap = buy twice" maxim, Court_S seems to have had success with his Masata unit, and like the CSF it's also a factory fit design rather than needing to change to hoses and clamps.
I think in this case I'm willing to take a punt on the Masata, I can always move it on if I feel it's not right.

Good to hear the injectors have solved the issue. Sounds like your dead injectors were quite bad; mine was only slightly leaking so the car started fine, there was just a very slight pop when it idled.
It wasn't too bad initially, but went downhill significantly over the last few weeks. Apparently #6 was really terrible, but none of the others were particularly wonderful either.I've got the old index 9s, might send them off for testing/cleaning and see if any are considered still serviceable in case another owner just needs one of two to match the rest of a bank.

The DCT is notorious for weeping slightly from what I can tell from my M3 research.

Sounds like your injectors were bad; the only physical evidence for me was a slightly damp plug in cylinder six. I’ve got a spare set of good index nines to fall back on for now.
As for oil leaks, they usually go hand in hand with BMW ownership too.

Is it even a proper BMW if it’s not leaking oil from somewhere?
But my Z4M can't be a BMW because it went 2 years between services, albeit only 6,000 miles, without needing a top up - amazing.
Maybe that's why the E90 takes another litre of oil.

The N52 wanted 1 litre of oil for every 2k miles that I covered, and the the N62 V8 4.8 just wanted to piss it out everywhere it could to be fair!

I all fairness this is pretty good; it seems to go 8k between changes with not more than 250ml needed at some point which I can live with. The 330i gets through 250ml every 1,200 miles or so.

N52s do seem to get through some oil. My 330i needed 2 litres for 5,500 miles between services so it's much worse than yours despite having new cam-cover and filter housing gaskets. 
Which only really leaves the sump gasket as the likely culprit, but it's cheaper to just keep topping up than get that replaced!
