BMW G30 - Engine management light

Vicxas · 17-05-2022 7:55am #1

Hi Folks,

Just wondering if anyone has seen this before. Engine management light has been popping up on the dash, no errors on the iDrive.

Brought it to my mechanic and he cant see whats wrong with it, i got an OBD reader and went through all the faults and cleared them one by one. Clearing a driver assist fault 800ac5 and that removed the Error on the dash.

A quick google seems to point to one of the cameras, but the cameras are working fine. Has anyone seen this before where a camera issue causes an Engine Management light to pop up?

There's a recall on the reversing camera for the G20. Had mine done recently. Could be similar on G30. Check out https://www.bmw.ie/en/topics/owners/bmw-recall.html#recallLookup and stick your VIN in to find out.

Left it in with Joe Duffy this morning at 8, got a call at 09:30 which is never good.

Adblue tank has an internal fault and needs to be replaced. 1250 euro all in,

Happy Friday everyone

Just get it mapped out for €100 or so?

A remap out of the adblue costs a lot more than €100, two months after my map out I’m left with a blocked dpf and car back in the garage, reversing the map will cost me €150, remove and clean the dpf then get a new adblue tank fitted, what a mess, no more adblue for me, soon as it’s done I’m getting rid.

this car will have cost me over €3000 on a car with fsh and 60000 kms, manufacturers don’t care about this built in fault.

common problem across most cars with adblue it seems.

Just curious, do you wait for the adblue to run low,/ get a warning before you top it up, or do you top it up when it gets to half?

I top up when it's at about half, I just chuck in a 10L drum, and never had any problems.

(Probably be cheaper to buy adblue at the pump)

As an electric car driver I see threads like this and go they have some tolerence. 40k km cost me about 600 euro. 100 euro in service at the main dealer (had to do nothing). 120 in tax per year. You would want to have a serious love for the diesel clatter to keep going. And no I dont drive up and down to Belfast in a day. I do about 100km a day

That's fine, but some of us can't afford to change, or actually like the car we drive and enjoy the knowledge of a 1000++km range.

If I drove like most ev drivers, I'd get 1.4k from a tank.

Lifes too short.

Why do you need to reverse the remap? Adblue and dpf problems are separate, no?

the map out of the adblue caused other issues - my dpf clogged 2000 kms later, I'm no mechanic so cannot explain in any detail but I had another tech look at it and he told me very difficult to get the adblue map out right, the first guys were not interested in helping find a solution and no guarantee once dpf cleaned that it would not reoccur.

If in a similar position then replace the part don't map out, experience talking here.

Me personally I’d just get the DPF removed

Better still to avoid adblue diesel vehicles entirely unless you do enough mileage, by enough more than maybe 30000 annually, I was a low annual km driver and only used it for cross country runs, very little local use as we have a petrol in the family as well, that way you are constantly using the adblue.

The fault is with the manufacturers, consumers should not have to face removal of dpf or bypassing adblue, its not fit fir purpose, my tank cost €1264 plus VAT ...I'm finished with adblue now, hybrid or electric next..

I think when it comes to DPF’s/Adblue/EGR the fault is usually with the consumer buying a diesel car when it doesn’t suit them. I think you would be a bit of an out liar using diesel correctly and still having issues. The only reason DPF’s and Adblue exist is because of EU policy on emissions. I think manufacturers would happily remove them if the policies around emissions were to change, but clearly this is not going to happen.

I think pretty much all modern engine failures can be blamed on government policies around emissions or safety. The likes of downsizing engines and adding turbo chargers and trying to squeeze as much power with as little co2 has massively decreased engine reliability.

Spot on in all respects.

I had a 2010 Merc, had it six years and 73000 miles with not a penny spent on it, just preventative maintenance, my driving style has not changed yet I had these problems, these are manufacturer problems not driver faults.

with all their engineering expertise the adblue system they run with is not fit for use, changing an adblue tank with built in pump ( stupid design ) after less than 35000 miles ish is shocking as was the cost of the replacement tank AND the pump is still in the tank, the manufacturer could not care less about engineering a permanent solution, buy the same car new today and it has this fault in it from the factory.

I’m a car guy and knew nothing about this until it visited me, bet there are many more like me.

I will get my own back mind you, there will never be another in my driveway, bet that scares them !
