Wondering if any of you can help. DPF light on my 2009 CX7 (62,000 miles) came on so after unsuccessful regen had the DPF cleaned by a mobile DPF specialist.

Ran fine for 200 miles or so then DPF light and engine management light both came on and car went in to limp mode. Took car to garage who said it needed a new DPF but they wouldn't do the job!

DPF cleaner guy said he would fit it if I sourced a new DPF, which I have done but had to import from Germany (I am in UK). He came to fit it today but said that he can't get the temperature sensors which are connected to the DPF off without damaging them so I'd need to get new ones.

My question is - what exactly do I need to buy? Spoke to Mazda who said that there are four sensors, but DPF guy said I only need to get two.

It's a lovely car but getting parts for it is an absolute nightmare!
