2.0cdti ECU update for DPF causing poor fuel & loss of performace

[Boroboy]

Well yesterday the car wanted to do a regen and it went into limp mode (despite it's done loads in the past with no issues).

I checked the error code and it was pointing back to the temp sensor vauxhall only replaced in August.

I rang the manger of my local dealer directly, he got me to come in as soon as I got there my keys were taken and the car was took in.

They ran a diag test and found that Vauxhall had just issued a TSB with a software update due to a software weakness in the ECU.

They did a static regen then applied the update error gone for now but we will see All in it took 1:30hrs.

On getting the car back it seemed to have it's power restored back to normal.

Time will tell if the MPG picks up.

From what I've read it's usually a faulty sensor that causes the dpf blockages, due to over fueling. They may have cured the symptom, rather than the cause.
