2008 e93 325i sport issues/ e92 m3 for sale
Discussion
Hi guys got a 2008 325i (3litre version) I believe that’s makes my car the horrid n53? Having a few issues with the running of vehicle just wondering if anyone had similar probs and what the issues turned out to be. The car is currently on a bmw comprehensive warranty so hopefully I’m covered, finger crossed.
Symptoms-
Excessive smoke from exhaust esp on idle, but once warmed up and on the move the car still persists, I’ve read on here some people experience similar so maybe not a big deal
Sluggish at times, and really lazy, have to really give it some to move
Rough idle on cold start up, takes a good middle to settle to 600rpm mark, very rough idle when I try reversing when the car is cold
Oil dropped 1 bar on the computer this week, I only had a rocker cover gastket replaced in October, so lost a slight amount of oil in 3 months
Recently had a diagnostic carried out by a friend has my local dealer wanted me to wait 6 weeks for a diagnostic check (ridiculous)
Error codes found where as follows
30e9-nitrogen oxide catalysator, ageing
2b07-nitrogen oxide sensor electrical
2b06-nitrogen oxide sensor lambada
2afb- nitrogen oxide sensor lambada
To me this looks like a sensor issue, possibly the cat, but my mechanic reckons it’s a lot more to it and needs investigating properly, obviously because I have a bmw warranty i want them to look at it rather then paying someone else, just wondering what everyone’s thoughts where?
I was also hoping to part ex this vehicle once the work was carried out has I wouldn’t sell anyone a car with faults, I’m in the market for a e92/e93 m3 now, if anyone knows any good ones knocking about please do point me in the right direction. I spotted a 2008 dct white e93 yesterday up for 17k with 55 on the clock, do you guys think that’s abit too much? I would happily pay that for a lci model but seems abit much for a 11 year vehicle, I’d obviously want to sell it after 2/3 years (don’t hang on to cars for that long) so I’d at least want 10-12k back in resale, can’t see that happening in a 2008 car, thinking to maybe just pay that bit extra and get a 140i, or even do the dreaded thing and ditch bmw all together ( die hard bmw fan here) and maybe get a golf r or Audi s5 but to me it’sjusy not as special as the v8 m3, I only really found myself in my 325 has I couldn’t afford a m3 at the time, but I do actually love the 325 the 25% it decides to run right
Any input appreciated
Cheers guys

+1 on noxem although if the OP is flipping it I'd not bother. Probably needs injectors too. Though I doubt its smoking, is just the cold weather.
Just partex it as it is, the only running symptom seems to be cold start misfire which is likely an injector (or six) leaking when it's sat overnight.

Cheers for input guys, I’ve googled the emulator you suggested, looks interesting but at 300 odd quid for a car I’m not looking to keep for much longer I’m not so sure, as I said the car is under warranty so I’d ideally like a fix which is covered through that, if not I’ll just have to get it sorted, is the emulator worth it, it won’t upset the car and throw out any other faults? A mate of mine has a e93 320i and experienced a nox error code turned out to be leaking injectors as you suggested but I thought maybe my 6 cylinder engine would be different to his 4. And also mine seems to state intermittent and ageing so that kind of had me thinking otherwise. Where injectors ever recalled for the n53? I know ignition coils a HPFP were and my vehicle had them replaced in 2012 according to Bmw, I have no paperwork documenting this from previous owner.
Does anyone know if a recall was announced for injectors on the n53? Model in question 08 325i(3.0L) I’ve rang bmw and it seems every recall has been done but they didn’t mention anything about injectors as they only mentioned what was showing as completed and outstanding. Having a mare atm rang my local dealer yesterday stating problems and diagnostic results, they now need to carry out there own diagnostic check and given me a month wait grrr!
M3 related question- where rod bearings ever recalled? If not would warranty cover then?
Cheers

If it's got a rough idle, have you left it running for a while to see if you get a yellow engine light on the dashboard?
When I got my N53 330i, it soon turned out to be obviously knackered (rough idle, and misfires while driving), but the dealer fobbed me off with a "no engine light = it's fine" type of comment, and I couldn't argue with that because I had indeed had no engine light. But eventually I discovered that after leaving it idling for a while, wobbling away roughly, after a while it would become super rough, like a washing machine with a brick in it, and after a bit longer the engine light would finally come on.
Once I'd made this happen a couple of times, I took it to my local BMW franchised dealer, and they seemed to have no trouble quickly determining that there was an injector fault that required at least the replacement of all 6 injectors. I didn't have a warranty, so their incentives were a bit different in my case - I was just trying to marshal evidence for rejecting the car - but clearly they can in principle figure it out...
In the end, the dealer I bought mine from paid for a full set of replacement engine bits (injectors, coil packs, spark plugs, fuel sensor, NOx sensor, something like that...), and the car has been fine since. So if you can get all this done, and you otherwise like the car, I wouldn't automatically dismiss having it repaired. There's apparently a 2 year warranty on this stuff, so if you're going to change car in that period, then no problem.
Mine still uses some oil (1 iDrive notch per 1500-2000 miles), but this just seems to be inevitable.

Cheers for the helpful reply mate, the car does actually settle down after a minute or 2 because I’ve let it idle on start up since we’ve had snow recently, so typically let the car warm up for 5-10mins, no warnings on dash or anything, if however I do attempt to drive within the first couple of mins it’s very rough, even whilst shifting gears it really struggles almost as if it going up hill. I guess it’s just the really cold weather? I did change from a Castro’s edge 5w30 to a Castro’s edge 0w 40 since last service which was back in June 2018, and problems have happened since then, but surely a 0w40 would perform better as its thinner? Cars on 82k miles now so maybe a thicker oil is better, what do you guys think? But yeah it’s seems as if I do lose a notch every 2-3k miles, it did previously also do this but I had the valve cover gasket changed and assumed it was fixed, it’s now done it again so who knows, maybe it’s just in the cars nature.
Good on you for getting the garage you bought the vehicle from to pay for all your repairs, I take it problems occurred shorty after purchase? I’m haveing same problems with my local dealer they seem to fob me off a lot because I’m turning up with a old 2008 car, all they seem to be interested in is finance deals and flogging brand new cars. I actually dread going in, just a horrible snotty nosed environment but hey. I’ve read on a forum somewhere recalls were sent out for checking and replacing if Nessacasry the injectors I just don’t know if it was for the n53. Someone mentioned a breather or something other for the smoking of exhaust?

Just had a light bulb moment when I mentioned my last service!!
1 of the spark plugs wells had oil present, in turn making making 1 of the plugs black, sure sign of a failing valve cover gasket! Thing is plugs where changed in June 2008, and gasket in Oct 2008. Therefore the new set of plugs may have been affected since change. A bad plug can cause misfires and poorer fuel consumption right? Thing is I haven’t checked since and bmw upon changing gasket didn’t mention anything either, could this be my problem? Could it also upset the nox etc?
Cheers, what a palava I want a new car and all this grief grrr

Oil in spark plug well was from your cracked cam cover. And yes, it would F up your coilpack and plug for that cylinder. Presumably whomever got the cam cover replaced also had the sense to replace the coilpack and plug at least for that cylinder.
These engines really need someone who knows what they are doing and in my experience that is not necessarily a BMW dealer. If they are fobbing you off find another dealer!?!?! The warranty - once again, assuming it's mondial - is very good but it requires access to a dealer which is helpful. A rare beast indeed.

A very rare beast! No naming and shaming but it’s a dealer in the west London area! There literally on their hands and knees with you when there chasing a sale, warranty work I guess is costing them money so perhaps that’s why there keen to see the back of me, who knows! The gasket was replaced by same dealer, no mention of replacing coil or plug so I highly doubt it. Have a few highly respected Indy’s within my reach but not really established any real relationship with either has I’ve always gone bmw (on my 5th bmw) and not really had any major probs, touch wood! Would you say 5w 30 is more suited to a moderate mileage n53? Or you think it don’t matter? It’s all within spec! Just thinking though the car sounds a lot more tappity since going 0w40, maybe some thicker oil with stop that
Just a a quick follow up, car went into dealer last wheel, they diagnosed the nox sensor as failing, replaced (luckily under warranty) car still runs abit iffy? I’m baffled! Noticed a pause/delay in 3rd or 4th as I kicked down the vehicle the other morning, never happened before. And weirdly the car is now running close to empty tank (60/70 odd miles left according to computer) low warning fuel alert comes on at 50ish. But anyhow the car is running sweet. I’ve noticed this in the past also but ignored it, but car seems to run really nicely when fuel is low. Got me thinking. When sufficiently filled up the cars hit and miss, seems like it struggles upon acceleration, hard to explain but it’s almost like I put my medal on the metal and it’s like I’m driving with a flat. Baffled can’t really do anything has no error codes are present. Dealer also found a slight leak to gearbox (sweating apparently) cleaned up and told to return in a month or 2 to see how it’s getting on. But at this moment in time I’m thinking of runniing the car on 5 pound between fuelling haha. Maybe premium fuel would help, as I’m guilty of using the cheap unleaded at supermarkets
