General tech_How to manage a DPF_Audi 2.0 Ultra

Hi, 

There is loads of info on the DPF problems with Audi 2.0 diesel Ultra engine around the forums.      Could we collate them to one Technical thread.🤔

Essentially the question is:  If you want to buy an Audi with the 2.0 diesel Ultra engine:

• Can you protect yourself, or are you MAD?😐
• Are there day to day, cost effective ways you can reasonably 'manage' life with a DPF Ultra to avoid major disaster? 😊

Absolutely NOT a mechanic🤐 - just putting down notes that I've seen:

1. Your Driving style - avoid short, stop start city journey if you can. Once a week do 20-30mins continuously at say 2500-3000 revs 'cleaning drive' to get exhaust temp up to burn off soot;
2. Branded fuel, Q would using the higher grade e.g. Shell V power etc. have any benefit?
3. if you notice your car starting a self regen during a journey ( idle revs rise to a. 1000 ) then take car for the 20-30mins at 2500-3000 revs 'cleaning drive'.
4. if you notice a self-regen starting when you park ( fan running, lots of heat, smell of burning...get back in car, don't just leave it parked ( as unlikely to achieve a full regeneration) and do the 20-30mins at 2500-3000 revs 'cleaning drive'.
5. Fuel additives ( Q. ones that just 'help maintain', and  ones that 'clean'; Every tank?
6. Ad blue - does the brand make any difference?
7. Ad blue injector - cleaning the nozzel;
8. Get an OBD reader to monitor DPF info. - Q what specifics to look out for?  What related sensors prone to failure, and that it's wise to try replacing - before you go into more expensive fault finding
9. Shorten intervals between oil changes ( 6 - 7 - 8 k? ), and use correct oil spec;
10. Do you factor in getting the DPF professionally cleaned, and if so on the car / off the car?

Basically - if you are careful and proactive - can you consider buying a 2.0 ultra....... or is it just a certain time bomb waiting to go off ( probably on a friday, in winter, at rush hour, with unsympathetic passengers )!😧

Maybe people could add in their experiences, and what was done on their cars that fixed DPF problems?😀

Thanks!
