Petrol particulate filter

[shewdz]

Avid reader of these threads and been both unlucky to have the PPF light come on several times, but also found it relatively easy to clear using the high revs method.

Bit of a new one today though. Car went in for a service and MOT. I requested the PPF related software update i had read about on this forum. When i went to pick the car up, they told me i would have to bring it back to them in a few days. The software update has caused the engine light to come on (which they stated was normal) and to fix it then need to request a "wire" to make the engine light go away. Sounds like they are making it up as they go along. Anyone else had similar?
