Interesting suggestion - how does that work?
The cat or post cat lambda sensor gets a bit tired. The spacer moves the sensor away from the gases so the sensor thinks the post cat emissions are ok. It’s a slight bodge-but-it often works and it’s cheap. Also post cat emissions don’t really affect the engines operation. (I’ve done it before and it worked).
Wife drove car Sunday pm and the EML came on again.

Front hoses normally seize to the hard pipes, care is needed to remove them. Rear brake pipes are often rusty.
Cheers. I'm hoping there isn't too much drama since the callipers look in great nick with it being a Japanese import but I always like to lean on the experience of others so I can be prepared for the silly little things that can go wrong but turn it into a mission. Since this thread is the Oracle and in case anyone needs the details here at part no. and prices for 2 x front and 4 x rear brake pipe hoses on the pre-lci 325i:
BMW Edinburgh
1. 2 x 34306790550 £32.99+vat each
2. 2 x 34306798523 £21.36+vat each
3. 2 x 34306792253 £23.98+vat each
Total = £187.96 (prices with discount)
Pentland Components
1. 2 x 34306790550 £11.30+vat each
2. 2 x 34306798523 £10.94+vat each
3. 2 x 34306792253 £11.11+vat each
Total = £80.04
Gone with the latter. Didn't go for braided as I've seen a few people describing them as tough to work with and needing a bit of rotational force to get them into position. Didn't want to make a bigger job of it than it needs to be.

I don't think the early ones have IBS.
I'd have to look again but I don't think mine does (I think it's a late 05 build).I bought an Exide battery of similar, if not same, capacity and swapped it in. No issues a couple of years down the line.
I'd be inclined to throw the battery on the CTEK and see what happens. It's also got really cold quite quickly - and when I "broke down" and got recovered in the Lakes, I actually worked out it was just some moisture had managed to get between the battery terminals and the connectors - a quick clean up and all has been well since.

HEL hoses aren't much more than the standard BMW rubber ones. Fitted some a while ago, no bother at all.Since this thread is the Oracle and in case anyone needs the details here at part no. and prices for 2 x front and 4 x rear brake pipe hoses on the pre-lci 325i:

Bit late but I've always found them much easier to fit, especially if you spec them with the swivel end fittings. Plus, I reckon they would've been the same price if not a smidge cheaper.EDIT - I've just realised I've posted twice in this thread now. Hope the straight six 335 diesel is still welcomed.
Lets talk service items
Car just clocked over 100k this morning, the next service is due so what should I be doing / looking out for?
Plan to do the following:
pollen filter
air filter
oil & filter
manual gearbox fluid
diff fluid
I have heard the thermostat & egr thermostat, water pump and egr can cause issues around this mileage?
Checking the crank case breather (not sure if I have one being 07?) Cleaning EGR and inlet manifold has also been suggested.
What else should I pay close attention to.
What do you guys run between oil changes? In my Ti it was every 10k.
Cheers
Side note- what oil do you recommend for the various driveline components?

I'd probably look at the breather in the valve cover too. Maybe inspect some of the vacuum hoses, since they can cause funny issues on the M57.Also, The air filter is a TOTAL PAIN. Otherwise, I think you're spot on with it all.
I also do every 10k, because it normalises out nicely. Every round number is time for a service.

Remove strut bar to get the filter out? madness. This time I will be keeping stock of consumables, including the stretch bolts attaching the strut bar! I also do every 10k, because it normalises out nicely. Every round number is time for a service.

New to E91 ownership (current car is E38). Got a 325i touring and I would like to do the valve cover gasket. Anything else I should consider "whilst I'm there" valvetronic seal comes to mind.
I did this last month. May as well do the oil filter housing and oil cooler gaskets whilst you're poking around in there. A lot of guides out there but would remove the coolant expansion tank and disconnect various other items to give yourself as much room as possible, removing the cover can be fiddly so you want to give yourself as much clearance as possible.eezeh said:

I'll be honest, mine have come off a few times and I haven't replaced them. It's the same as the the E46 where the bolts holding the chassis brace underneath were supposed to be single use. I also re-used them. 
On your recommendations of oils, I'm sure you know but any LL-04 5w30 would be my go to for an M57. For diff oil, a good 75-140 should do the trick. I couldn't comment on gearbox oil though, as mine was done before I bought it.
As also mentioned, I'd do the pair of thermostats. The temps you're seeing isn't enough, my E46 330d did similar temps too and needed thermostats. There's one for the engine and one for the EGR cooler. Replacing them made a difference in fuel economy, and in your case will keep the DPF happy, as these cars won't trigger a DPF regen if the temps aren't right.
Otherwise you should be sorted. Maybe a scan of the DDE if you've got INPA/Carly/other diag kit and stick some miles on it.

The diff oil is Castrol Syntrax, 75w90, the 140 is for LSDs. The brace bolts on the E91 do tend to come loose if not replaced.
That's good to know, thanks Helix. I've not replaced mine but also not noticed that they've loosened off when removing. I'll look into some new ones though. Is it just the outer ones, or does the one in the middle also need replacing?
I've got an MXS5.0 and it's dead fine. It will 'recondition' batteries, and works with AGM and sealed lead acid batteries too. it will also do smaller batteries, like motorbike ones.
ETA: There's a week and year stamped on the negative battery terminal.
