My freind is going to view one tommorow and he wants to know what he should be looking out for please?

he said "I've looked on the internet and I can't find ANY common faults. 2000 330D SE (Top Range Mod Cons etc also It's got M-Tech Wheels, Dash and Steering Wheel) 101k miles full service history Failed one MoT on corroded brake hoses. £4,999 value"

oh and "And can you ask if it's Chain cam driven"

Can't find ANY common faults? Ha!

330d's can and do suffer from injector failures, turbo failures and if it's an auto it'll have swirl flaps that can break off and be ingested into the engine, wrecking it.

It has a cam chain, not a cambelt.

What to specifically look out for? Make sure it feels perfect is about the best advice I can say. One in good condition drives completely smoothly and is very refined. Look for odd vibrations when driving, any other than a virtually 100% smooth experience suggests there may be problems.

Common faults will be wearing upper/lower control arm bushes (You replace the whole arm at £250 an arm inc fitting to fix this), turbocharger failure, swirlflap failure on automatic models (This can write the engine off), injection failure, electrical issues with the climate control, check for rust, etc.

If it doesn't feel perfect, walk away. There is too much scope for a nightmare if you buy one thats less than mint.

He clearly hasn't looked very far then.

Brake hose thing is quite common. If it has M-tech wheels on a 2000 SE they are almost certainly cheap fake ones from Ebay with poor quality tyres, seems to be the way the older E46's are going. Good to hear it's got a dash though, wouldnt want one without one of those.

Hope he realises what he's letting himself in for. When working, they are great cars, but unless you are buying it for something to be more than simply a way of getting from A to B the issues that will crop up will make it considerably worse value than virtually anything else.

Yes.
 
Injector failures and turbos being the main things, unless like said its an auto, where other things can be a problem.
droplinks into the injectors can crack, cheap to fix though :]

turbos can be bought recon, saving loads. injectors are about £200 from GCP, or near on £300 from BMW.
 
Reminds me of that weird program on TV where they had a "crack fox" :D

why do turbos fail? is this due to people not letting the oil circulate before turning it off?

One of the reasons was because of the original crankcase oil breathers being a mesh filter, when this blocked it caused back pressure in the oil system and could cause turbo failures amoung other problems. They were being replaced by BMW a couple of years ago with a new breather without the mesh but there are still cars out there that havent had them replaced.

generally lack of lubrication or heavy particles in the oil, causing bearing failure, or entering through the intake, causing impeller failure.

To avoid make sure you let everything warm up before boosting it up and even more importantly don't just stop and shut your engine off straight away. Also frequently change oil/oil filter and make sure you have a decent air filter.

so pressure in the crank case caused the turbo to fail. anything more specific than that? the only way the turbo is going to be connected to that will be the oil return and surely the oil pump will just keep forcing it through

ah... so long life servicing not being so smart perhaps?

air filters are so crucial, it really makes me laugh how people will skimp on things like that

If theres back pressure in the oil system I assume that it means that the oil can't be sucked out of the sump by the oil pump hence causing oil starvation to the turbo and oil to be sucked past the piston rings as well in some extreme cases. Not having it happen to me I can only go on what ive read about it though.
