E91 Straight Six Bearding
Discussion
I went the other way from an E46 330d to a 125i Coupé, and in the 6 years I've been back in the petrol I don't think I ever missed the old diesel. The shove in the petrol is only 1000rpm higher up than the diesel so I don't really find a huge difference in day to day driving, and when the road opens up the petrol is far more satisfying to extend.
I did something similar in 2014 when I went from a 123d to a 3.0Si Z4Coupe and it never felt sluggish to me.
But the Z4 really came alive at higher revs, whereas the 123d just died!
I've stuck to petrol 6-pots ever since and would never go back to the devil's fuel.
Especially as I don't do enough miles for diesel to make any sort of sense anyway!

yep - nothing like the legs of a wide rev range and an open road!MikeM6 said:

Absolutely, shame it's so damp and cold on the roads, trying to use all 8krpm is a little squirrelly 
Never had that problem with the 335i 
Day to day though the S65 engine drove me mad, and I much prefer the usability of a turbo in that situation to be fair. I wouldn't want to use my 370Z(it only revs to 7500rpm though) either as a daily, but I do really enjoy it on the right road though for certain.
A turbo for a daily...and a NA for occasional use works well for me.
Noticing with mine that I'm getting more transmission/diff noise as the miles go on, which I guess is to be expected with the miles now nudging 125k.
Now and again I do the frivolous "what would I replace it with?" exercise, which usually leads me back to something very similar, if not the same. Or something vastly more expensive.

Have you done the diff/gearbox oils?
Changing them with some sort of additive, like Ceratec might help quieten them down.
I don't see anything about to replace mine, short of spending a lot of cash.
I haven't, though I had been thinking about it and had added it to the list of things to do. I've got quite a lot of tyre noise, too, so I have a number of different sound frequencies coming at me. I actually suspect that a new SKF wheel bearing I fitted on the front is louder than the old one.Changing them with some sort of additive, like Ceratec might help quieten them down.

I’m almost at 1 years ownership of my E91 330d. The car has been great and completely reliable in the 15k miles I’ve done in that time, however it’s certainly not been cheap!
03-20 Service £160
06-20 2 PS4S £288
08-20 Refurbished 3 wheels and a new one from BMW plus centre caps and badges £700ish
08-20 Brake fluid, adjust handbrake, clean up a couple of oil leaks £212
10-20 New windscreen £100 ins excess plus new wiper £30
11-20 Mot, 2 rear shocks plus misc bolts, mounts etc £520
11-20 Major service, overhaul rear handbrake, new oil filter housing gasket £676
11-20 Tailgate struts £20
Needless to say I’m hoping the next year is less costly! At least the car isn’t really depreciating much which offsets the expense somewhat.

You call that ‘completely reliable’?
Blimey.
A friendly reminder for owners of the petrol variety (namely N52) owners to have a check of those DISA valves.
I replaced the starter and CCV system in mine over the past couple of days, and found...
Followed by the flap and pin inside the inlet. Fortunate it didn't cause any real damage. I checked the smaller one, and that was fine. A new one from BMW is £260, though.

I found exactly the same thing in my N52 a few months ago. I think we've both had a narrow escape...
My 330i has starship mileage so I struggle throwing big cash at it, so I replaced both DISA's with Chinese knock offs for ~£40 each.
They appear to be identical to the genuine parts just without the logos... Fingers crossed.

What made you go looking?
I've been chasing a low engine speed stumble/hesitation when going at the throttle quickly since I've had the car. It was always worst when coming out of the Peage fast lanes in France, picking up from low revs in third.When I was pulling the manifold I wanted to inspect them anyway, and that's what I found. The big valve can be removed with the manifold on, the smaller requires the manifold to come off.
From reading, the bigger of the two valves is more likely to fail and come off. They can sound rattly before they do fail. New BMW valves look to have a different shaft which should help them not fail. I bought a BMW one, as it could be in my hands in less than 24 hours.
