What is a 'DPF/EGR removal'? Is that a power improvement thing or a mpg improvement thing?
What is the cost of this? I know a remap is around £400 so if the above is another £400 it's not really worth it compared with the fuel savings. What sort of fuel savings could I expect from a 1.9 and a 2.4?
I had a Leon Cupra Tdi before my ST and I averaged about 45mpg which seemed to be what most people were getting and not a million miles off the manufacturers claim.
Both, removal of the DPF/EGR and the required remap stops the engine having to 'regen' which is effectively burning more diesel to heat up the exhaust gasses to clear out the DPF filter which becomes clogged. This cripples mpg obviously. The remap which is required to stop the ECU performing the regen also results in power and torque going up, basically because it's a better map for the turbo etc I think, I dont know the ins and outs, just know on a 1.9 the generally obtained figure is something like going from the stock 150hp/250lbft to 198/300 or something like that, the 2.4 is even more and must be crazy, something like 250hp and 400lbft after remap
Anyway those cost between £400 from places like Motormech Ive seen to £600 at AHM etc
I can say that I've owned my 1.9 Ti (09 plate) since June 2011 and it hasnt been great on fuel, BUT I do alot of town driving in and about Glasgow, and the 159 is a heavy car made heavier by Ti 19" alloys I'd imagine so it's a lot of car to get moving and start/stopping etc
I have to admit my mpg average is currently showing 36, but thats ALOT of short journeys and town driving. Taking it a run up to Dundee at the end of the month to clear it out a bit, but I've done a run to Aberdeen and back last year with an average closer to 50..about 46 or something. Not TOO bad
But then you get out of it and look back and think mmmm
So aye, worth it probably, lol - no issues in 7k miles so far apart from the odd squeek/rattle and blue and me annoying me
