Hi guys I have a 2011 2 liter TDI

I having dpf issues so I went to my local automotive shop and picked up a bottle of Wynne's dpf cleaner which sorted the problem I then got a dpf light again on the dashboard so I went back to my local shop he didn't have the cleaner but was advised to get the Wynne's dpf regeneration in the black bottle he said it's better than the Wynne's dpf cleaner in the blue bottle 

I'm now in limp mode and I got engine management light on 

Did some research I needed the cleaner not regeneration additive I know have car booked in for a dpf clean 

Is there anything I can do to reclaim some of the cost of the dpf clean from the automotive shop ?

Thanks

In a word: no. Nothing you can put in the fuel tank would have made more than a slight and very temporary difference to a blocked DPF, so you would have had to get it properly cleaned or replaced anyway.

Ok but the regen additive didn't help 

My point is the shop sold me the wrong stuff

No they didn’t. People buy these types products all the time in the hope it will sort the underlying problem. 

Well I got the dpf cleaned 360 miles later i got the same problem 

I invested in a obd scanner tool

And my regeneration bank 1 flagged up as a error code 

As anyone else had this happened to them ? 

Thanks

Could be an exhaust temperature sensor. Ideally you need to read soot levels and the temperature for that bank. If it’s not getting temperature it’s clogging again.

If it is the sensor which one do I get ?

What’s the engine code? My understanding is these exhaust temp sensors are utter pain. Access may be difficult, plus they are usually difficult to remove and sometimes need drilled out. Not sure what OBD scanner you’re using, but you need to get access to VCDS or Autel to check, then you can run live data.

it might even be exhaust pressure sender. Check against your engine code. https://www.lllparts.co.uk/catalogs/audi/RDW/A3/646/2/253/253062
