E91 Straight Six Bearding

It might be the end of the road for mine soon gang

Pads and caliper, fitted fine and all good. However, I took it out when testing it? Filled it with fuel, and holy Jesus we’ve got a strange engine noise. The only way I can describe it is the whining noise that an old E55 with the supercharger makes when they first start (link for your perusal)

Check the oil filter hasn’t collapsed.

It is engine speed dependant and sounds loudest at idle. Doesn’t matter whether hot or cold, it still does it. I’m hoping for it to be a bearing in one of the pulleys on the front of the engine, but it sounds farther back than that.

I’ve dropped it off at the father in laws garage for one of his lads to look at this week, but he wasn’t very happy with the sound either. We’ll have to see how it goes.

Even more disappointing is that fuel economy seemed markedly better now the thermostat and rear caliper are doing what they should be now!

Will do, Helix. It only went in there 7,000 miles ago in July. It was a MANN one too!

Should be ok, I was hoping you could have a quick easy fix!

I've somehow managed to lose the spare key to my e91. Can anyone recommend somewhere to get a replacement? I'm guessing the cost will be eye watering?

I’ve bought keys from this supplier before (£25) and my local auto locksmith cuts them and codes them for me (£60).

I paid 165 quid at BMW for a new key. Wish I'd known this at the time.

Just been quoted £190 from a local auto locksmith!

I have a March 2007 build 330i (N52) which does not have Efficient Dynamics (start/stop) and the battery is getting a little slow to crank now the mornings are getting colder.

Do I need and AGM battery?

If I don't need and AGM battery, is there any advantage to having one?

Thanks

[JakeT]

You don't NEED an AGM battery, per se, but they can last better. I'd stick a normal one in since they're cheaper. If your car has iDrive or some certain other options you need to register it to the car.

Me too! A used N52 is £1500, and I am not paying that. If it's the end of the road, it's getting sold and I'm buying another stter E46/39 to run around in while the wallet recovers. Something like a 520i.

Well, given the original has lasted 12 years, I think I'll go with a wet filled battery. No iDrive on mine, but Ill check with Carley App to see if it allows me to register a new battery.

Anyone buy the grey 330 estate from AT, plate ending WOB? I was temped by it, apparently a few issues but no margin for the seller. He seemed a decent chap and knew his stuff. I was temped as it'd have been a cheap base even if it needed a bit of love.

Kind of glad it's gone, so I can't buy it!

Aaaand the misfire is back. Just now on a quick trip up the road. Pulled over and as I tried to turn the PAS also went and then the dash lit up like it was an early Xmas. tt.

I suspect it's the potential oil leak issue - prime suspect rocker cover gasket. Haven't had chance to check it but suspect it's leaked enough to now be causing issues again. Not sure why PAS cut out, but maybe required more load than the misfiring engine could deliver, and hence cut out? Is it clutched the PAS? Just trying to think if the car is able to cut the pump in such circumstances

The PAS thing and the dash would lead me to think you should be investigating electrical gremlins too. I know you've got Carly - does that give you any codes?

Ok so a week off and first day back it decides to start missing 1mi from home. Crawl it back amd then spend 30mins finally replacing coils on 3-6 that I'd not yet done. All fine again.

Until I was almost at work and after turning a corner the PAS goes again, no throttle either. So definitely not misfire related this time as it was humming away smoothly in the background. It's going in Wed for the misfire to be looked at (suspect cam cover gasket) so I'll have to get them to see if they can trace this other issue. I'll check codes again tonight as I cleared them earlier after doing the coils

Random though, but anything odd in the airbox/inlet?

Jake - really sorry to read about this, I hope it can be fixed. I never experienced any noises similar to this during my ownership. My initial guess would have been something belt or pulley related, to my knowledge they are largely original, or perhaps the water pump, but I understand you've recently done this again.

The oil filter is an interesting suggestion, I didn't realise a faulty filter could result in this type of noise being created, after some googling, it appears it can and some owners have experienced it with 3k mile old filters.

I hope it makes it to 200k miles!

[JakeT]

Ah Chris, no worries. It's 'old car stuff' isn't it. Nothing against you as a seller or previous owner. I've really piled on the miles now, at 10k since purchase. I am also hopeful it's a pulley or belt driven ancillary. Even if the engine is toast, I might drop a lump in it. Since I don't want anything else currently. It's a very good all rounder, and I have enjoyed smashing the miles on it. The bit I'm most sad at is that I can't drive it!

It'll all pan out though, I'm sure.

Ferris, I'll take a look in the airbox when I get the chance too. Saying that, the filter was new 7,000 miles ago too. The box was hoovered out then.

[JakeT]

Don't need an engine, yay!

A/C Compressor bearing has had it. I'll most likely fit a compressor, since after almost 150k the compressor will be old and worn out. Better than a new engine.

Good news! Still a shame, but considerably cheaper than a used N52 lump! I’m chuffed it lives on, a great car.

There is a company near me who recon these units, they do a good job low price with a warranty, send off your unit and it comes back exchange or same unit, he does lots of BMW compressors (can you get it removed and send it off?). Based in Chertsey, can send contact details (they have done a 130i and 525i for me, much cheaper than getting one off ebay or local motor factor).

It's a sigh of relief really. Meant to be off to Belgium and Germany in 2 weeks time with it, so no plan changes needed. Plus it means I can keep racking up the miles as quickly as possible.

Funny you should say that, I've just ordered a new DENSO compressor, along with a tensioner and belt from Opie. Were it not for needing it back with me pretty sharpish for the above mentioned trip I'd have it rebuilt. I still might do, so that I have either a spare, or will sell it on. Compressor, belt and tensioner were a shade over £300. Is it the end of the world? Not really, no. With A/C gas and labour, I'd imagine we're looking at £500 all said and done. Could be worse.

[ferrisbueller]

Better than worst case, glad you got it diagnosed quickly.

Result!

So, back to my woes. Turned right on to the A34 dual carriageway tonight at a roundabout where you have to be "on it". Lost PAS and power again. Then realised the engine had cut out. Restart and off again. DId it again a couple of miles later when turning right into a side road. I see a pattern emerging.

I do a u-turn in a junction nearby to my house to line up better for parking on the drive. It's a u-turn to the right. And hey presto, engine cuts out. It's low speed tighter turns with no throttle that seems to be incurring the issue.

Read codes and aside from all the non-communication ones between various units, it's listing: 2E1B Firing, Cyl 4.

Specifically not misfiring. Googled and seems it could be anything - Fuel pump, spark plug, coil (replaced today so unlikely), alternator, Battery...

Now I know what triggers it hopefully I can drive around it until it goes in on Wed.

[Obison]

I'm sure i have read about momentary cut outs or low power for a second can be the fuel filter, usually shows when turning from a stop at junctions etc.
