    Hello all - very new to this forum and wanted to get some advice on the above car.

    I have found a 60-plate metallic black in gorgeous condition, 88,000 miles on the clock, private seller. Full BMW service history. Sat Nav, i-drive, cruise control.

    However, following on from a conversation with a mechanic friend of mine, he mentioned some worrying and well known issues about the N47 engines - namely the timing chain.

    Now before I bite the bullet and make an offer for the car, I wanted to get an idea on people's views. The guy selling says the chain has never been replaced as has never been a problem, and said it will be good until around 120,000 miles, at which point it probably would need doing. When I took it for a test drive, the engine sounded spot on - no ticking or rattling from inside at 1,500 rpm, which seems to be the benchmark test.

    However, I have been reading numerous horror stories online about these timing chains just giving up without any warning, causing thousands of £££ of damage, if not whole replacement engines. I spoke to a BMW specialist, who says he changes 100+ of these a year on the N47 engines (just as a precaution) at £1,000 a pop! Keeps him in business he says!

    So my question is, is it worth taking the risk - as I have completely fallen in love with the motor already, and as far as I can see, everything else anybody has to say about the model is all positive. I really don't want to get an A4 TDi instead or a Skoda or something, as those car just leave me utterly cold.

    So any thoughts would be much appreciated! Cheers!

    Has the private seller shown you plenty of proof of regular lower mileage oil changes? has he been the only owner?

    If the oil changes have been long intervals then walk away, BMW say 18k changes but others on here say around 10-12k miles.

    My previous E90, 320d late 2008 with the problematic N47 engine I had mine changed every 13k miles, was sweet as nut when I sold it after 5 years but mine was low mileage. My friend had the same engine similar low mileage (50k) to mine and regular oil changes, his chain snapped!
    BMW footed the repair as he had purchased the extended warranty.

    There are thousands of BMW N47 Diesel engines on the road, you maybe unlucky, and get a huge bill, but then you maybe lucky too and have a sound engine,

    My latest car is the F30 again with the later version of the N47T engine.

    Hi - thanks very much for your reply..

    No I haven't seen evidence of the regular oil change services, I guess that is something worth looking into.

    Am I right in thinking the timing chain issues were more of a problem on the earlier N47 engines, say between 2007-2009, or are they a problem right across the whole range?

    I'm just relucant to spend 6.5K on the car, only to be faced with a bill of £1000+ (which lets face it is getting on for 20% of the car's value!) in 20,000-30,000 miles time, which I will prbably do in 18 months!!!

    If I budgeted for a little more and got a newer model (F30?), are then engines updated and therefore no suffer with this common problem?

    Many thanks again for your help.

    If you're not in a rush to buy then you're better off holding out for a newer f30 - by all account they're generally a better car

    That's what I thought - quite a bit more expensive though, obviously as newer. :(

    Prefer the look of the E90 series though, not quite sure what it is... just something about it.

    Not a lot of difference to be honest, my F30 the wheelbase is slightly bigger, hence giving a better ride. Inside is slightly roomier, especially for rear passengers.
    Mine has the auto box, with an 8 speed gearbox, so it is more fuel efficient.
    There are plenty of later models available, and prices do vary, but I am sure you will find a later model, with a much lower mileage and probably not a million miles away in price.
    Having said that there are a number of late lower mileage E90's on the market too, plenty to choose from.

    I'd hold off on the N47 and possibly looking at something with the M57 if you still want an E90.

    My M47TU2D20 is still going at 214k with regular oil changes, I'm not sure I'd be saying that with an N47 engine..
    One thing to consider is there must be thousands of examples on the roads of that engine and it's still not 100% clear if the issue was fixed in 2011 or 2013.
    I did find an article that said they saw one example (320d) which has it's chain go at something daft like 28k.

    If you're willing maybe go for it and spend the cash on getting it replaced?
    I do agree with you on the E90 looks vs the F30....Then again, when the e90 first came out I didn't think it was a patch on the E46.

    I was considering an N47 320ed for a while but the timing chain issue and some reports of gearbox problems has put me off for now.

    Or just look for a similar age 325d or 330d. The extra spend on fuel will more than make up for smoothness, power and sleeping at night.
