545i playing up !

Recommended Posts

A couple of weeks ago the car started running ever so slightly rough, I was on my way to the airport with the car fully loaded. Then a bit of hard acceleration brought on the EML.

 

The message was informing me that heavy loads on the engine may damage the catalytic converter. I switched the engine off as it was skaking quiet badly, but the eml and the shaking then disappeared when I restarted the car..

 

Since then no eml. But the car feels like it's misfiring under medium to hard acceleration and sometimes it will misfire when idling. It's just not as smooth as before.

 

1st thoughts were a coil pack, but I got the carly adapter yesterday and it gives 3 faults for the engine. All VVT related, the 1st is the vvt power supply and the other 2 are faults on both banks presumably because of the power supply ? 

 

Has anyone any advice on where to Start? 

 

Thanks for any help!

I'm assuming by VVT, it's for the valvetronic system? Check power connections. There have been a few reported problems with that on the N62.

 

I had the same symptoms on mine, turned out it was the cylinder head breather valves were broken £20 for parts but another £180 for dealer to diagnose and fit.

Thanks Andrew .

 

Are the power connections are under the cabin filter ? 

 

I also cannot get my battery to fully charge (go green) which may explain why I'm getting fault codes for things that seem to be working fine. Fuel consumption has gone from 20mpg to 15mpg as well.

I can't recall where the connectors are, but sounds about right from memory up top near the bulkhead.

 

Sounds like the engine isn't running right at all if you are only getting 15mpg.  Worse for me was 21mpg and that was towing a caravan.

 

Get a new battery if you don't know the age/history of it. Get it then coded to the car.  Weak electrical supply can cause all sorts of issues in E60's, but there may be more to it in your case.

Below is from carly today after checked connections and fuses in the IVM. 

 

If I start the car from cold it will miss every 5 seconds at idle. If I drive it with a very light throttle it will stay like this, but if I apply a bit more throttle it will misfire very slightly and then every 2-3 seconds at idle. If I floor it the car will be hesitant but will eventually take off.

 

The engine management light only came on when the car was fully loaded with luggage and passengers, and this was when it started to shake at idle.

 

I have checked the vvt module which has no signs of being burnt out like some I've seen on you tube and also the IVM, and all seems fine. Is there any other way of checking ? 

 

Any more help would be greatly appreciated especially as my sat nav has also now stopped reading the disc ! Plus I reckon it needs a battery as well.

 

This 545i is starting to bite after less than 1000miles ...

It looks like a supply issue. You have an IBS fault and the voltage dropped to 9.5v. Is the battery going flat? I would check the alternator/voltage regulator and fully charge the battery.

Wife has just come back in car to say the EML is back on with the car shaking again. So it looks like whatever the problem is causing a misfire on cylinder 1. There's also a problem with the ibs as well now. 
 
The battery voltage is 12.1-12.2v switched off. Switched on I get 14.2v to 14.5 but when I switch lights and heating on the revs rise 300rpm but the voltage doesn't go below 13.9v .
 
Would this discount the alternator and the voltage regulator ?

I had similar issues and it turned out to be one of coil packs that had rubber ‘boot’ missing at bottom. It let the coil pack move about giving similar symptoms to yours

I just got a new battery and bloody hell if it hasn't sorted the vvt power supply faults. So thats good and the mpg on the test run was much improved. But i still have the misfire on cylinder 1 so I'll get a coil pack tomorrow and hope it sorts it out. 

 

Despite the misfire the car feels so much more responsive that I'm beginning to think the vvt has been faulty for a while as I never got a EML for it, so would have never checked if it wasn't for the misfire. Plus the mpg has been terrible since I bought the car a few months ago. I got 28mpg on the test run, compared to the 14mpg average i had been getting.

 

I'll report back after the coil pack change but thank you for the help so far.

Did you code the new battery to the car?

 

No but will do tomorrow. I've bought the same spec one that BMW put in the car in 2013 so hopefully it will be straight forward. Bosch coil pack being picked up tomorrow so u just need to find out where bank 1 is.

This is the car I bought off here. To be fair jomo had done everything possible to it so I can't complain about a battery and hopefully just a coil pack.

5 years isn't good for a battery ties in with your IBS issue.

 

My battery was original when I got rid of it at 12 years old, I had an IBS code logged too but no ill effects from it.

It wasn't the AGM battery if that makes a difference ? but jomo only used it on a weekend so it was sat around a lot for the 5 years he had it, plus my wife uses it for very short journeys throughout the week so no matter what car we have, we always have battery issues eventually. 

 

I'll look into a battery conditioner I think for this one.

I used mine for 12 mile round trips for the last 4 years I had it.  Did an occasionally long journey but short trips were the norm, hence petrol.

 

Ctek charger is what you want.  From Amazon.

Yes I have the MXS 5.0 as well, excellent unit.

 

Just to say that repeated short journeys won't be very good for that lovely V8. Said to be a contributor to valve seal issues on that engine.

Now that ties in, I didn't know that. One of the MOT exams I put mine thru the tech mentioned that when I asked about the oily smell in the workshop when mine was running. Still it blew well below max levels on the emission test for the next couple of MOTs.  Wasn't an issue for me but I don't think the engine would do that mileage again before serious intervention.

We do around 3-4k a year with the wife using it mainly during the week to go to the gym and shopping. All trips are no longer than 2-3miles there and back. 

 

At the weekend I give it a long run or we all go out as a family somewhere for the day. 

 

My previous car was a 3.2v6 Alfa Romeo which sounded amazing but also didn't like short journeys! I do use my van whenever I can and so does the wife, but I can't face having a small engined run-a-bout when it comes to going somewhere at the weekends. Diesels are also out of the question as well .

But yes you are doing very short journeys, shorter than mine. That won't be good.  I did about 6k a year in my E60.

 

But having just got mine back after a 6 week break, the sound of a decent engine that can pull sweetly and smoothly is thoroughly enjoyable and is a must for engaging driving.

Replaced coil pack this afternoon after trawling around for a good hour to find a bloody torx socket ! Wtf are they going to think of next ?! (£12 quid later I have a set of 5 ) 

 

Anyway car is fixed and flying along like a 333bhp car should. For some reason carly will not clear the codes but I'll look into that later.

 

Now time for the new bonnet badge to go on as a treat ...

 

Next job will be liberating the sound as it's just too quiet even for an executive car.

Yup, I had to go out and buy a 3/8" ratchet to use with my torx socket. I had previously managed to get away with using my 1/2" drive ratchet plus adapter but there is no room in the N62 bay to do that.

 

 

The F10 is a charm too. Torx bits, torx sockets, hex bits and splined bits are all needed.
