We have already covered the V6 & V10 TDIs in plenty of our vlog and even touched on the V12 TDIs recently, but we have never really done much on the 4.2 V8 TDI, which is a shame really, its a beast of a motor!
Whilst having this customer vehicle at our facilities we fabricated a new DPF Delete Kit compatible with the Audi Q7 and VW Touareg 4.2 TDI engines as well as EGR and Swirl Flap Deletes!

@@mikemayers9353 Sorry Mike you are wrong, Any turbo charged petrol or diesel Audi or not can be mapped and the darkside boys are amongst the best in the business. Stage 1 requires no hardware certainly not rods or bigger turbo. If you are planning on taking a RS3 to 1000 plus hp then yes I agree its going involve major upgrades but most poeople are happy with a decent hike in power and torque but keeping it reliable but with better drivability, just a map will easily give you a genuine performance gain.

@gavinjacques 3 года назад

I Love mine had it for 7 years, It came with a sorry (DMS) tune so similar numbers. Price mine was £82k when new ouch! They will win many traffic light GP's, on a run at motorway speeds they are just as efficient as the v6 but towing is where they are excellent. Mine has spent most of its life towing a 2 ton caravan and you basically didnt notice it on the back. The only issue I have had is one of the dpf pressure sensors failled. A common fault on these and a cheap part but half the car has to come appart to change. The actual performance is alot closer in the real world to a V12 because the latter ones of these have the 8 speed box. Yes the brakes are poor and expensive oem work the best. Just a little insight from another V8 Q7 owner.

@DarksideDevelopments 3 года назад

Bring it for a Dyno one day, thanks for the input!

@alfbed75 3 года назад

Had my Touareg v8 tdi mapped by DMS back in 2014. Never felt that good to drive despite a reputed 400+ BHP. Took it to Darkside and had it remapped again with the DPFs removed. It went from 408bhp on their dyno to 398bhp. You might imagine that I was slightly disappointed, but torque increased from 870Nm to 950Nm. The losses were only above 3500rpm. The EGTs dropped significantly from 960c to about 880c. It is so much smoother and better to drive. I can't rate these lads work highly enough.
