Problem! BMW 520D

Hi Guys, I'm looking for advice on what to do as i'm in a real dilemma.

So the story goes:
I own a bmw 520d which i bought in early 2013 which had one previous owner full BMW service history but driven around 80000 miles. The car then was under warranty and throughout my ownership havn't had any major issues. (just had to replace tires/break pads wear and tear etc)

I was dropping my parents off to Heathrow on a hot July day, when during the roadworks section (near Luton) I got a sign for the first time -
"Drivetrain. Maximum power not available. Drive moderately"

I obviously had getting my parents off to the airport to catch their flight on my mind and the fact that we were on the motorway miles away from the BMW service station I use.
Unfortunately, I decided to ignore the message and continued driving. The car didn't feel any different and so I drove on (around 75 mph) about a mile later the sign came up a second time and the car felt as if it was loosing power (had to rev it more to keep at the same speed) so I went to the slow lane of the motorway and kept a speed around 55 mph. As it was the roadworks section there wasn't a hard shoulder or any safe place to stop so I continued driving for around 2 miles - all the while the car felt more lethargic and a whining/whistling noise grew from the engine.

Around the end of the roadworks I looked in my mirrors and could see white smoke visibly coming from the exhaust and then I knew I had a serious problem - as I pulled up on the hard shoulder there was a sudden increase in white smoke which almost covered 2 lanes of the motor way. It was so bad that a motorist decided to call the fire brigade as he suspected the car to be on fire.

I immediately switched off the engine and we evacuated the car. Naturally I called my roadside assistance and they sent a recovery person their way.
At that time Highway patrol officers came and asked to move my car as it was in an unsafe position. They noted oil coming from the exhaust and suspected a blown turbo. they advised me not to drive it and said the would tow it with their Pajero. But the car was stuck in park (automatic) so had to turn it onto put it into neutral - when I did so it made a horrible (almost mechanical) noise and blurted out black smoke from the exhaust. Any way the tow truck came and again had to switch the car on - this time the red engine oil low sign came on (not once but twice) and the car was taken to sytner BMW on an emergency booking.

I don't understand much about cars but I knew that low engine oil was a bad bad sign. Anyway Sytner came back to me and told me the car was in a state. At the very least it needed a new turbo, replacement of DPF and investigation into extent of possible engine damage. They qouted me in the vicinity of ÂŁ5000 !!!!
obviously I thought 5 Grand was extortionate so I decided to take the car to the most reputed BMW specialist in town. The car is out of warranty and I didnt think to pay for additional cover because the car never gave me a major problem and that I thought it to be still on the young side. I didnt imagine I would asked to fork out something like 5K so soon.

The sytner guys didnt even bother to put some extra engine oil out of courtesy and took ÂŁ50 for diagnostics. When I took it to the independent guy, he switched on the engine started to rev it and the car started "knocking" the engine was gone he said and thats where I stand.

So the options are to go down the dealership route and get charged an extortionate amount
Go down the DIY route find my self a new/second hand engine and get things done independently
sell the car as is - as a non-running vehicle.

I'm the kind of person who doesnt know too much a bout cars and doesnt want too much hastle. But I want to get the financial best deal out of this mess and thats where id love some advice from the members of this forum.

Thanks in advance!

Yes that is an option. But the question is the hastle of a second hand engine worth it? I'm no expert on cars - who will buy the second hand engine on my behalf - how will i Know the new engine is installed correctly - I think insurance has to be involved when replacing engines? Say I do all this - what happens 6 months down the line if that engine has a major fault.

I know a car with a damaged engine is worth little - but what is a fair price for a 520D in otherwise good condition with a damaged engine?
The thing is I'm clueless as to how much all this is going to cost. So its hard for me to make comparisons. Does anybody have an idea roughly how much the car would sell for as it is. Also how uch it would cost for new engine, exhaust, DPF and labour fitting cleaning etc?

The turbo is shot and as soon as you saw the white smoke you should have pulled over.
But you may be lucky and all that is needed is a refurbished/new turbo and you are good to go.

You're right - as soon as it was safe for me to do so - I think i did pull over.

I WISH it was just that - but the car engine noise is sounding really unwell. Both sytner and the independent garage have said that the engine is knackered. Which is a real shame because the car is just shy of 5 years old and although its done around 112000 miles I feel a BMW engine should be much more sturdier.
Also there is visible oil around the exhaust indicating a serious leak.
Thanks

Decent engine with decent turbo bought and fitted,id say ÂŁ1000 or thereabouts.
But I don't understand why you are writing off the engine as the turbo may be the only thing that has gone kaput.

Oil around the exhaust is normal after a turbo failure as the turbo sucks the oil out of the engine and the turbo then runs on the oil as it is sucking it out of the engine
and firing it out the exhaust.

Sounds like a blown turbo, quite normal for them to fail.!

To keep costs down source a reconditioned turbo (google it, there are a number of companies) and have a garage fit it for labour costs. I would of also insisted on a diagnostics printout from Synter so you could see the fault codes for yourself.

being brutal ide bite the bullet and sell the car as a none runner and move on, it will never be the same again and will prolly be a problematic lemon, you will drive it always with doubt and fear in your head if you waste ya money fixing it...


unload it and move on my advice...

That's exactly what the guy at the garage said - He's well reputed - I just cant fathom how a car so young could go so wrong :mad

That sounds like a very likely scenario. The problem is what else may have suffered from the loss of oil - could just be the crank bearings or you could have problems all over the engine.

For the record the turbos usually fail because of insufficient oil changes (the BMW intervals are the absolute max) or a blocked breather filter (should be changed or checked every 3rd service).

Is the car and E60 or an F10? The reason I ask is an E60 520d with a shot engine is worth investing a lot less in than a tidy F10.
Yes that's the consensus and what I believe to have happened. The oil has been duped out all into the exhaust. We drained out all the oil over the weekend and I'm attaching the photo.


Mind you we added around a quart of oil to that when we took it into the garage. However, the mechanic said I MAY have lucked out and had enough oil not to have damaged for running bone dry. What do you guys think?
Any way he said the next plan of action is to try start the engine without connecting to the exhaust and see what's causing the knocking noises and locomotion.
Still a long way to go with the car in terms of if the engine is ok - we still need to sort out a new turbo and of course see what damage has been done to the exhaust and the DPF.
We're taking baby steps but will keep you all updated. This board has been quite informative for a NOOB like me and please feel free to add anything if you feel I've forgotten anything.

trouble with these modern diesels they are that highly strung,complicated animals and near the operating limits of the engineering that when summat decides to let go the damage and knock on effect can be quite catastrophic and expensive...


that smooth petrol like power and punchy performance comes at a price sometimes...


ya should get fair price for it as a none runner if the rest of the car is good, a garage or person in the know will prolly jump on it if they can source a replacement half engine minus all the external ancilliary gubbins...

There are three breakers in the UK that specialise in BMW's and will probably pay reasonable money for your defunct car.

Forest auto breakers in Cinderford (on my doorstep) Quarry motors in Sheffield and Alexander's of Somerset surprisingly in Somerset, suggest you call round those three and either way up buying a new engine or selling your non-runner to them

I don't know who your garage "chap" is - is he a recognised BMW specialist? If he is, get him to source the replacement engine, if that's what it needs - there are several BMW breakers who would have an engine - firms such s Quarry motors, or FAB direct. If he isn't a BMW specialist - find one locally, they will help you.

It rather sounds like the turbo went, and emptied the sump of oil in the process, if that is the case the crank bearings are probably shot - hence all the knocking and rattling. Depending on how long it was run with no oil, it could have caused extensive damage, or could just mean replacing the bearings, fitting a replacement turbo, cleaning out the intercooler and pipework, and you are back in business for not too big an outlay. Sourcing and fitting a replacement engine will obviously be quite a bit more expensive.

I don't know what you paid for the car originally, but a car with a blown engine is worth peanuts, if you can afford it, it would be better to fix it.

It depends what the car is worth to the OP

if he cant afford to take the loss or break it for parts then fitting a second hand engine and turbo would seem to be the cheapest way forward ....??

Of course it would help if was DIY inclined

i had my timing chain break at 360,000 kms - got a second hand engine fitted and drove another 100,000 on it before swapping it for an F10

At the time i just wasn't in the right position to change the car AND the rest of the car was in good nick

im gonna be brutal and frank again but ive rarely seen especially on this forum one of these type of grenaded later highy strung modern diesels fare well after a garage rebuild, there is always issues with power and delivery and smoke etc etc afterwards, if it is damaged but saveable ide still get rid of it myself...
