I have a PD130 B5.5 (2001 plate but 2002 model). Read so much about it, but some say its a bad idea, some say its great. At 137,000 miles its due a clean, but I was thinking of just taking the thing off.
Ive done it before on an MGZR and it actually drove better, just took ages to warm up in winter. However, it needed mapping as the ECU light came on. Ive also read it only does this on 2003+ models.
