I'm with you on that one been on some sites and given advice and told it not right
I've got 2.5td p38 and had some good pointers on here
That's fair enough, only do what you feel good with mate. Mines a 2.5 DSE. It worked well enough on mine for 16,000 miles 😁 and for a 2p mod the performance in pulling up the hill I live on from a cold start was so noticeable that SWMBO asked me what I'd done to the car.
I also cleaned out the inlet manifold of all the black oily residue and the intercooler. Don't do either of those near your wife's white patio paving. It's cost me an extension to cover up the mess :😭
P.S. The only other thing I can think of is if the ECU has the EGR programmed in and does it need removing? My Q7 did ahem. It doesn't now. The EGR delete kit is a posh version of my 2p (which is invisible).
