Helpppppp. My astra 05 cdti went into limp mode and now seems to be an intermittent fault. This happened about a week ago as the other half was out shopping.luckily she managed to pull over and turned of the engine. We had a guy come out to it,plugged it in and said there were no fault codes stored. Sure enough there is no engine management light on now but the problem seems to happen quite often(usually as I'm going to work). It's had two different sets of diagnostics on it and they say they cannot find a fault for it.
Any help would be greatly appreciated as I think the cost for getting it checked is getting more and more each time I take it to a garage
