Hi Ive just bought a Roomy with the 1.9 lump in it. It's my first diesel (I know Im late to the party) but I was wondering if there are any changes worth making to improve performance and reliability. Im tempted by a remap if anyone has any recommendations either way. Would this be safe on a 75k mile car? Also do people remove the EGR function? The service history has become a little sketchy in its later years so I plan to do a thorough service and this may well include a cambelt/water pump renewal as I can find no documented evidence it has been done. Are there any particular frailties I should also look out for? Cheers Ben
