Well after this morning I'm on my 3rd RAC call out in 3 months. This one after a 280 mile journey from London to Ireland (ie- not a 'school run'). Basically I dont really know what to do now. I cant rely on it at all and so I dont know whether its worth owing it anymore. I'm really sad about this as I think it looks awesome, drives awesome, has an awesome feel to it and I generally just love everything about it. Everything except the part where I cant drive it anywhere without it clogging up and requiring an RAC call. A real problem seems to be the conflicting advice given to me. The manual says go over 60kph and 2000rpm in 4th or 5th gears. The first RAC guy who came out said to drive at 60mph in 4th gear and get the revs near 3000rpm. He said driving at 70mph stops it regenerating. If that is true then its nice of the manual to not mention this. The next time it happened the RAC guy said 60mph was too fast and to do 40-50mph in 4th. Today the guy said that was rubbish and just drop it into 3rd, hit 4000rpm and ragg the engine for 10 mins until the exhaust gets hot enough to blast a cloud of smoke out the back. This is a terrible bit of new technology and does sod all for the environment seeing as you have to drive in a rubbish gear, burn loads of fuel and then get rescued by another van in the end anyway! My advice to anyone considering buying an Audi diesel with a DPF is simple- DONT! ps- I've posted this in the Diesel forum as well, in case people dont see it here. Let me know if I should merge them/ delete one.
