Particulate Filter
Friend has just taken his A6 2.0L TDi into the garage today as last week a light appeared on his dash, then 60 miles later the car went into limp home mode!!
His is a 2007 model and he was told that in 2007 new legislation for emissions was released in the UK and this newer filter had to be fitted to all new diesels. It has cost him £300 to get it sorted and was told that expect to be back in 12 months time - every 12 months. Its due to the unit needing to be at a certain temperature to work - clean itself - but the bloke (at an Audi independant) reckons that it never happens......... Does the A8 3.0 and 4.2 TDi's suffer from this also? And is the guy talking out of his @rse Cheers

From what I've been told the DPF cleans itself every 150 miles or so by dousing the filter with lots of diesel and burning the crap off it at intensely high temperatures

maybe needs to try a bit of spirited driving

I think both the 3.0 and 4.2 have DPFs.. They can be coded out as part of a map process.
The issue is people buy diesels and just do the school run in them, so the engine never reaches operating temperature for long, which is what's needed for the DPF cycle to work. Hence why over the last 6-7 years, there's been regular stories of people having to pay for new DPFs when they're not running the car long enough. 30-40 miles every other weekend should be enough as keep it clean. But it needs to really be motorway miles at a decent speed to allow car to warm up and DPF clean process to kick in

On the other hand, with a few exceptions, they're the default option for bigger cars, unless you have "specific requirements".

I spoke with a mechanic last week regarding coding out the DPF and was told not to do it. Excess smoke and soot on the tailpipes don't appeal to me

Thanks everyone for your replies.
I think he mentioned a new senor also?
