We have a 2008 Zafira 1.9CDTi automatic and every few weeks its warning light comes on to say we need to get it to a Vauxhall dealer. The handbook says the fault is with either the diesel particulate filter and/or the transmission electronics, but it drives with no noticeable difference. The first couple of times I took the car for a long motorway run and left it overnight. That cleared the problem, but this time the light came on after a motorway run and doesn't want to clear itself. There's also a strong diesel smell once the car has been run and the engine stopped. I'm concerned as we have four children (youngest 1 year) and this is "mum's taxi" so needs to be reliable and not always at our local dealer. I see from your website that the DPF is a well-known problem but do you have any other suggestions as to what this might be? And after just 14,000 miles in 14 months, increasingly in town driving, have I bought a pup? If so, would the petrol, manual version be a better option?
