It is the 1.6, 90. diesel version. It can happen in any circumstance. After the first time, we drove from North Yorkshire to Dover A19, A1, M11, M25. M2. The second time on rural roads in France. We where asked if fuel consumption was up or performance down, no to both There is no effect to the ride or drive when it is illuminated. Mileage is just over 14k. Service is up to date. We have asked the question about codes, but only told there is no problem, except, each time it comes on, do we look at it and say "no problem" or do we spend £71, to have it hooked upto a machine, Apart from the above, we like the car very much. loads of space, a comfy ride, loads of gadgets and cheap to run. Only gripe is a major service at £199 every 12.5K Regards Deck1ng
