IIRC there's a date on the battery somewhere.

CTek: I use the MXS 5.0

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. smile


ETA: There's a week and year stamped on the negative battery terminal.

Will check part nos later against realoem but fairly sure this is original



Anyone got a view on which ctek? MXS5 or CT5?
Yes. It’s the original one as it has the date stamped on the -ve terminal.

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 think it’s all of them. Though if you’ve not had a problem with yours I wouldn’t worry too much. I’ve just seen a few used ones come loose after repairs, but maybe they weren’t torqued up correctly.

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. hehe
As have i.. hehe

JakeT said:
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.
Would explain why the dpf was removed and cleaned just before I bought it.. scratchchin

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.
helix402 said:
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.
Thanks! Ill have a look at getting some syntrax on order, reckon i'll go for quantum ll04 for engine as theres a tps outlet near the partridge dealer, and will look into the gearbox oil.

Currently attached to the Z4 in the garage which hasn't been driven for many months.

In actual fact, the battery on the 330i feels a bit on the way out. Takes a second longer than I'd expect to crank. Might chuck the CTEK on it overnight.

Chucked the CTEK on it...illumination only up to 3 (bit odd given wife has been driving car today). We'll see how much charge it retains until tomorrow morning.

Mine always light up half way even when I connect up after a three hour drive (on various different cars, too).

Was up to 4 this morning (i.e. 'ready to start car'). Started with no issue (as expected). I'll probably try and have it plugged in over the weekend.

I'm having an issue where my car creaks like a boat when I turn the wheel when it is stationary, left and right.

As I have some down time I may tackle it myself but don't know where to start.

Any idea what it could be?

Its an e93 335i.

We'll look over the fact it's an E93 winkwinkwink


Front suspension top mounts are classic for that, as are balljoints on the front suspension that have gone dry, or any steering column joints. Is it all the time? Or only certain conditions?


If you can, have someone steer the car with the bonnet open, and have a listen out for where the noise is coming from. Putting your hand on top of the shock towers can help too. Just don't get your hands caught up in any moving parts.

Very good point, I must read thread titles with more carefully!

But appreciate the response, it happens pretty much all the time less so in warm weather or when the car has warmed up.

Let us know how that goes, I have a really odd squeak that I can't find or suppress. As for the gate trim issue, BMW actually redesigned the plastic trim which I found an article for when I was pushing for warranty repair on my old one. What age is the car?
Anyone know the difference between the two? My intention was to shave a bit off the plastic and apply a polyurethane anti chafe tape over the repaired area
Just revisiting this to post a link: https://www.newtis.info/tisv2/a/en/e91-320d_tou/re...

It's unavailable at the moment but fortunately I have the print out from when I argued with BMW about it. I've scanned it in in case it is of any use to you:





Here's how bad it was on my old E91...

There's another aspect to the issue of rust in that area, I've recently found. Those covers appear to also form a drainage route arouund the tailgate frame, intentionally or not I don't know. But the lower clip for the cover, which has a gap behind it which would allow water to drain through, isn't that large and so gets clogged up with grime.

This then builds up and you end up with a massive wet clot of muck sat against the metal frame of the tailgate, which is also being chafed by the cover. I gave mine a good clearing out recently - something I'd advise others checking, especially it's it's only a 5min job.

Good shout, I'll get that done ASAP as still trying to clear random areas of crap that is causing water ingress.

Is there a thread-recommended roof bar/box combo for a raised-rail e91? Preferably that comes in black.

Raised rail E91? What does that mean?

I've got a pair of whispbars that mount between the rails (pre-lci) with a low profile Calix box

I have a pic somewhere -will have to go digging

Pre-LCI, yes. The later rails were flush right? Whispbars are on my list so keen to see what they look like, thanks.

Another vote for Whispbars – I have a set that lives permanently on my car. As the name implies, they're quiet.

Can't comment on roofboxes as I've never used one.

This morning, battery flat as a flat thing. 8.6V according to my voltmeter!

Really surprised as I had it on the CTEK last week for a 24hr period and got it up to Level 6.

Current spec is 540CCA and 70Ah.

Makes sense to get something a bit beefier, but if I get something with different specs, does it mean it'll need coding?

2006 model E91 330i. No stop start. (if that makes any difference)
