I have the following issue. On the same hill around 20 miles from me and only going the one way I get a error message "System Fault Message" and the car goes into limp mode. Usually I can stop, turn off for 30 secs, restart and all is good although the error message takes about 5 mins to disappear.

So far I have replaced the Brake Light switch, reasonable argument for this. I have replaced the Coolant Temp Sensor as Peachy has had a similar experience but neither has fixed the problem.

I haven't had the codes read as the nearest dealer is 30 miles away but maybe my next stop.

Has anyone any further ideas what might be causing this? its a very strange fault as it doesn't appear on any other roads except the one road, it is a pretty steep hill coming south out of Inverness. 2006 Supercharged

Silly question - have you checked the oil level? Just wondering if the steepness of the hill (and it only occurring going one way on the hill) indicates a sensor registering a dangerously low oil level. No idea if this a possible cause but it's an easy check. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Cheers for that but yep, oil level is good. 2006 Supercharged

Sounds to me like a fueling issue.. You need to get the codes read as a starting point.

Flack

Where in the country are you? I may be up in Inverness in the coming week

Mikey, i'm in Carrbridge, just North of Aviemore. If you're going to be up here that would be great. 2006 Supercharged

Mikey, are you going to manage to be up my way this week? 2006 Supercharged
