Hi All,

We picked up a 59 Plate 118i M Sport Convertible on Friday (private sale!) and we had the oil pressure light come on (RED) and my husband got a code reader on it (I have checked the BMW fault codes on another post but these don't match any - It might be the type of reader he has!).

Basically... Does anyone have any ideas and is this car just going to cost me a whole load of money and a headache...??

The car is tidy and I love it but my husband now regrets the purchase! I'm trying to be optimistic!

Also spare key is broken any ideas where is best to get a replacement??

FAULT CODES -
Engine - 2A0F
Engine - 2AF2
Engine - 2AF4
Engine - 2AF6
Engine - 30C1

Instrument Cluster - A559
Power Steering - 63F5
Central Roof module - A670
Junction Box Passenger - A6CF
Central Module in Drive Footwell - 9CB2

I also don't think it feels like there is any kind of power that i would have expected from an M Sport!

Might be running a bit rough on idle. But if the fan is on Level 1 the revs pick up and you don't feel it!

Is it F**ked?? :(

Thanks in advance!!!
Jess

Have you checked the oil level is fully topped up? (Sorry I'm not familiar with your engine). Spare key, I suspect you will need to go to a Dealership. Oh, and welcome by the way!

Welcome!

Doesn't look like good news I'm afraid. Code meanings in blue.

FAULT CODES -
Engine - 2A0F EGR valve
Engine - 2AF2 NOx sensor
Engine - 2AF4 NOx sensor
Engine - 2AF6 NOx sensor
Engine - 30C1 Engine - Oil pressure control, static

Instrument Cluster - A559 Terminal 30 shutdown due to critically low battery voltage.
Power Steering - 63F5 Steering performance reduced, insufficient power
Central Roof module - A670 Misting sensor
Junction Box Passenger - A6CF AUC sensor
Central Module in Drive Footwell - 9CB2 Headlight beam height control potentiometer defective
Best guess at fixes:
  • 30C1 is critical. On an N43, this most likely means the timing chain has stretched, the tensioner is failing, or the guides are in pieces in the sump. If the chain snaps, you're looking at a new engine so I'd recommend you don't start/drive the car - get it recovered to a mechanic.
  • NOx sensor needs replacing.
  • EGR valve needs checking/cleaning.
  • The two power related codes are probably just because the battery has gone flat at some point. Wouldn't worry about these for now.
  • The misting and AUC sensors can be safely ignored for now. It just means your climate control won't automatically switch on the demister or switch the airflow to recirculate when you're behind a dirty soot chucking diesel.
  • The headlight error means your lights won't level correctly. You can buy a replacement headlight switch off eBay for a tenner, usually the easiest thing to try.

Sadly the N43 engine is not known for its reliability and the first 3 issues are fairly common, it looks like the previous owner has knowingly sold you a lemon. If you can get your money back, I would :( If not, get the chain checked in the first instance - definitely worth getting a rough idea of cost for that and the NOx sensor before opening fire with the parts cannon!

Oh dear... the BMW garage and a BMW specialist are very near our house so we could risk the drive perhaps - its the bill that worries me! 30C1 :oops:

Thank you for all your help with these..

Yeah sadly with a private sale we have no protection i don't think. That being said I have sent the lady a message so she may reply. She might not but she is local to us. And met our two small children. I don't think they would have intentionally sold us a pile of poo as they were quite old and her husband is poorly. It was his car.

I wouldn't take it to the dealer, they'll quote more than the car's worth to sort. I'd be worried about this being a money pit even if you get the timing chain and egr sorted. Does the car have any service history? Based on the codes (and owners) I'd suspect it's been sat around alot between it's short tips to tesco and possibly not serviced regularly due to 'low mileage'.

I heard back from the seller she isnt interested, but she has suggested I call the garage who did the engine work in 2019. I think time might be too long ago but actually it has only done just over 1k since the work was completed (79,106 and now is on 80,055). So mileage wise its barely done anything,

As per the receipt -
replacement engine (new chains) @ £1295
fuel injectors @ £1000
Coils @ £60.00
Cam sensor @ £60

So i hold out hope they give it some kind of warranty but this is a bmw specialist garage and not a BMW garage..

Not serviced since 2019 as her husband got poorly and they didnt drive it... so yes your exactly right. !

Full service history up until that point

I was going to say you might be lucky and a chain replacement, new battery and long drive might sort out most of your issues but having seen that the work previously done I'd be bracing myself for the possibility that the engine is gubbed. Either the work has been done poorly (sump not dropped and cleaned out), the work was never done and the couple were ripped off or they'd run the car too long before getting the previous work done and it's been damaged. I'd be very worried that they've put 1000 miles on the car with the oil pressure warning showing.

Most decent garages will warranty their work for a year but I wouldn't be too hopeful if they last touched the car three years ago regardless of mileage. I think I'd be threatening small claims court, they've given you evidence that they knew there was an issue with the car.

Oh man... Sad times !!!

Well I'll call the garage that did the work and the local specialist tomorrow. See where we are.

The car i think was a good deal but not if it costs us more than £1k to put everything right. But I suppose it's the risk you take with buying private .... Oh well !!! Wish me luck.

Thanks for all your help.

Before parting with cash did you get it inspected, afraid to say it, but caveat emptor

you can get reamed buying from a dealer, the difference is, if car is under warranty then you have something, on a car with nothing you need an inspection by an Indy, seller won't be interested at all, not sure, of the questions you asked, did you get service records, ask why they were selling it, recipts are more important than the lies people use.

I bought a 91 944 s2 cab, I had it checked over by the AA, paid £150, they gave it a clean bill of health.

I got it home (£10k) found one rear wheel well, full of water, I THEN took it to a Porsche guy, found the brake pipes where rusted as well, £1k of repairs, sued the AA and the paid my repair bill.

BUT I kept that car for 10 years, only thing I changed in it was a battery and a clutch... oh, also found signs of it being in an accident, nothing in the paperwork or Carfax etc

Best car I ever owned,

oh well done you for getting your bill paid.

Unfortunately we just checked it ourselves. We felt we knew what to look for and check. It had a full service history / receipts up until 2019 when the seller got poorly. Which is why they were selling and i do believe. They are very local to us - another reason not to stich us up i think... they seemed genuine and they didn't use it at all really (only 1000k since 2019) - Also when it had the engine work done. Is it possible the fault codes just weren't properly cleared maybe? Or am i just being stupidly optimistic! ha ha

I did a full HPI check etc did the boring stuff like checking the VIN - husband did the test drive. all fine. It was only once home that the oil pressure light came up and we borrowed a reader and got the fault codes up.

Like i say hopefully tomorrow i will get some answers and one way or another and we will know where we are. but dont have a giant pot of gold coins so i am going to be blindly optimistic until i cant be any longer!!

Don't beat yourselves up about this. Sh*t happens!! Next time you know to read codes from a car before buying it :)

If the chain has been done recently, it's very possible the garage who did it simply didn't clear the broken bits of guide out of the sump. These get caught in the oil pickup and you get your pressure light. I'd be crossing my fingers it's that - a competent garage might be able to sort it by pulling them out through the drain plug. Might. If it was that, I'd hope the garage who did the work originally would help you out as it's their error.

Fingers crossed it's not going to break the bank. If it is, as nivens said, it could be worth filing with small claims court. If the seller told you there's nothing wrong but you can prove they knew something was, that's justification for a claim regardless of the general (wrong) belief that private sales have no recourse. Judges take a dim view on dishonesty!

Yeah that's what I'm hoping. And your right. Blissfully unaware of any problems I think is how they were....

So I spoke to he original garage this morning and the manager wasn't there with someone else on the desk he couldn't say if the work would be warranted or Even what was definitely done as he couldn't find our invoice just going by what I said ! But he thought it sounded like the oil pressure solenoid needed replacing in the first instance.

But he advised we get a diagnostic on in the mean time. so I've booked in with the local specialist who is just down the road from us - sadly not until Friday. They also said how unlikely it would be to be dead engine again... So soon!

It only had the MOT in July so I'm surprised it wouldn't have been picked up if there was a big issue - reading online however it seems most garages would just ignore anything not on the MOT checklist !!!

Maybe a good sign Mrs Langley because had the oil light been on during the MOT, it would have failed.

Really ?? I read online the mot testers won't check the engine etc if not on the MOT checklist and worst thing they can do is refuse to test the car ??
That being said I'm also taking this as a massive plus !!!


P.s you can call me Jess !!! I signed up with my email address so it took my username from there 🤣
