Hi All,

I had a search of the forum but couldn't find any references to this and so thought I'd ask to see if anyone can help?

After a good weekend back with the V12V, including the meet at Trinity, I just pulled off the motorway and put some fuel in the car. Went to restart it and had "Crash mode see manual" error message, some mis-firing and hazzard lights on. V strange at the time - so took the key out, tried again and it seemed to work fine. I just arrived at the hotel for the night and thought I'd check it again after 10 mins of being off, and got the same thing (needless to say I can;t find "crash mode" in the manual). I took the key out again and re-started it, all OK but now get "emission system service required" - for which I have seen some previous threads...

Anybody have any ideas where this has come from, and is it OK to drive the car if its working, or tow truck time...?

Any help would be greatly appreciated.

As the trigger point was putting fuel in I would check the petrol cap is on correctly. I am aware that the emissions warning can sometimes come on if the cap is not fitted correctly.

Thanks - checked that and seems the filler cap was on tightly. Now starts OK but just get the emissions system check warning - which goes when read pressed - otherwise seems OK so I'll give the dealers a ring in the morning and see how it goes...

Could be bad fuel. What did you put in?

Was BP Ron 95 - only £20 worth so just filled it up with fuel from another petrol station (shell) and straight after "crash mode" again and lumpy firing. Turn off - start up and all ok apart from the "emission service" which I guess will remain until I visit a dealer....

Get a cheap OBD2 reader to find out what has caused the MIL to come on. You can get them from about £20. Not sure if Halfrauds sells them.

Hi David,

Not sure if the case would be the same with the V12V but stands to reason... I know the V8's have a check-valve in the fuel filler, designed to determine when the car has crashed or been put on the roof. A couple of my clients who are particulary useful drivers have accidentally activated 'crash mode' on the track when they had a full tank of fuel (sloshing up the filler neck & tripping the valve.)

Is it possible that you got a little splash-back when filling the tank that might have set off the valve?

Hi Stuart,

Thanks for that - it sounds as an interesting possibility.....can't say right now but maybe that is the reason...It's booked into dealer tomorrow (still under AM warranty) so I'll see, but if I get anything useful I'll post to add the general knowledge base that keeps us all going!!

I hope you still frequent this forum. My car is coming up with similar strangeness and cutting out. I'm wondering if your dealer found the cause. AM wilmslow are still scratching heir heads.

Hi,

Well I think ultimately it was probably fuel contamination - water or something similar - I found out afterwards that the service station I stopped and bought fuel at suffered from flooding - how true - I'm not sure.

Anyway, after the dealership had the car (bad and sorry tale) they did not manage to find anything other than add loads of miles to test it and get a puncture, etc. but the car has been fine marvellous since then...hope that helps...
