New owner woes

[OptimusMiles]

Hello all, this is me first post of this forum and it’s not going to be a good one.
Bought my e89 28i (privately) a couple of days ago and after a good test drive and drive home, the issues have now begun.
I was driving about last night enjoying my new car when I got an engine warning light and reduced power mode message. I got the car home and my neighbour popped over with a cable and we plugged it into Carly app.
Vehicle status is very bad…
Main engine faults are

002F7C super knocking: injection shutdown

003447 engine oil too low

002C58 boost pressure control

002F78 super knocking cylinder 3

My neighbour knows a thing or two about BMWs and thinks this is related to the timing chain?
The car has done 81k now so is due a change.
Is the timing chain replacement something my (trusted) local mechanic can do or is it a specialist job?

If anyone has any kind of input I’d be grateful any information.

Thanks

Sorry to hear of bad start to ownership! Have you no way to go back to the seller- see if there is any good will toward the cost?

[OptimusMiles]

I’ll try but I’m not confident I’ll get anything back.
He must have know about the issues, just
Cleared the codes and sold it on.

It depends if your trusted local mechanic is capable of doing such a job, maybe you should speak to him? How old is the car?

[OptimusMiles]

I’ve just spoken to my mechanic and he’s not keen to take on the timing chain. To be fair he only has a small work space.
I’m in Dorset so have just given bmweymouth and call and they’re going to plug it in and come up with a plan later today. It might be nothing much. The car has been sat for a while apparently. The previous owner is responding to messages so that’s good. He hasn’t just blocked me.
The car is a 2012

The fault codes are not the ones normally associated with N20 cam chain issues…that’s not say the cam chain is great…it’s about a £1000 job for an Indy but does require quite a few special tools..

Low oil is a bad indicator of previous owner care..

Tricky to say what the issue are…could be a faulty injector although again N20 doesn’t suffer from this issue unduly

So what other faults are present?

[tomscott]

Instead of worrying just take it to a specialist and find out what's wrong and hopefully they will be able to diagnose and it not cost a fortune.

Not a good start but it is worth having a pre purchase inspection done before buying any vehicles privately. Live and learn im sure it will be sorted relatively easily.

They are getting old now ive spent 5k on my 17yo Z4M since buying it, part and parcel. Fix it and

[OptimusMiles]

Thanks for all these replies.
When the car checks its oil it says it’s just under halfway between min and max.
There are a few other codes for various things but they’re on my tablet. I’ll post them later.
We’ll see what the garage says….

Sorry to hear of your woes, my E85 kept beeping and the low oil light came on but the oil was halfway on the dipstick. Once I topped it to the full mark it stopped doing it, yours could be the same.

[OptimusMiles]

I’m new to all this e dipstick malarkey.
Seems like a huge pain in the arse?
So, the specialist thinks it’s nothing to worry about.
We thinks it’s been sat for a while and maybe not serviced as well as it could have been recently.
He’s changing some solenoids I’m going to give it a service and a good check over and he hopes that will do the trick.
Will get a price from them to change the timing belt to as I guess it needs to be done at some point soon.

[Pondrew]

The car has been sat for a while apparently.

That sentence plus the engine faults could be degraded fuel. It's unlikely but can happen. Have you put fuel in it since you got it?

The N20 timing chains tend to get quite noisy if they are on their way out, apparently.

Depending on what the BMW codes say, it may be worth topping the oil and sticking half a tank of Shell V power in.

[OptimusMiles]

I topped it up with about half a tank of regular unleaded.
I’ll take your advice and stick a tank of V power in next time.

[B21]

So it wasn’t low on oil…

If you plan to keep the car after a less than auspicious start then the cam chain/tensioner/oil pump drive chain is a very good idea..if that’s dine and it’s fed frequently with good quality lubricants it should return sterling service..

Is it an auto ?

[OptimusMiles]

The car said it wasn’t low on oil but it came up as a fault on the app.
Yes, I’ll plan to get the timing chain sorted for some peace of mind.
The car is a manual, and a very nice gearbox it seems to be too!

[OptimusMiles]

Hopefully some good news!
The garage has changed the oil and filters the champs are confident all is week.
He said the fault codes shown are usually the result of lack of use. And he also said the timing chain is sounding pretty good too!
