Hi Gareth, Steve, I've returned the car to the dealer now and have got a full refund from them. It came up with a crank sensor error also at start of week so decided enough was enough. A shame, as it was a nice car.

Yes, last owner for most of 8 years/100k use. Was main dealer history until about 4yrs ago, then independent garage. Last service history printout highlighted eml was on, so can't now be sensor as it's been changed. Am I right in thinking if there is a blockage or if there is a slight pressure leak to the pipes either going in our out of the dpf either side this can cause the eml to come on?

Thanks for the advice Gareth, Steve, much appreciated. I presume a new dpf will cost me £1000 plus? The car is really nice, just wasn't expecting these issues so quickly after buying it.

Dealer has now replaced dpf sensor, and put dpf cleaner in. Have given it good run out yesterday and made sure it had warmed up properly. Had it back for couple of hours, and light back on again with same dpf pressure error, so back to dealer. Been at dealers now for over 4 days overall, after buying less than 2wks ago, beginning to lose confidence in it. 

Just checked on the service printouts from last service, it shows eml light on, dpf pressure sensor 1. Is it possible this is linked with the issues I'm having now? Will having the dpf regenerated as dealer has suggested be helpful? 

Ok thanks, will leave it with dealer to sort to start with. New I may have some problems as you would expect with a car over 100k, but didn't expect warning lights in first week. Am I right in thinking this could be an ongoing issue, and is quite common with Audi diesels?

That's great, thanks for the advice. Is it worth me getting a plug in code scanner, never used one before so a bit unsure. 

Hi it's diesel, dealer got it scanned yesterday and it came up with needing dpf regen, I took it out for good drive at 3k revs, but light has come on again today. Handbook shows emission control light, think it looks same as eml. No other lights on, and this light is constant not flashing. 

Ok great thanks, presume if light is constant I can still drive it? 

Ok thanks, dealer got mechanic to run diagnostic yesterday and came up with dpf regeneration, but this wasn't the warning light on the dashboard. Yes got extra warranty, thankfully. Just wondered if I'm ok to run the car while light on, is constant not flashing. 

Hi, just got an A4 Avant this week after always wanting an Audi. It's higher mileage, just over 100k but great condition and decent history. Having problems with emission control warning light so any advice would much appreciated from forum members with more experience than me, thanks.

Hi, wonder if anyone can help, just got an A4 Avant, high mileage but good condition and history. Have had the emission control light come on twice now in less than week of buying the car, dealer cleared fault yesterday but it's come back today. Have given it a good run at 3k revs yesterday to clear dpf. First time I've owned an Audi, so any advice welcome.
