Dont forget that to refit the DPF the car will have to be remapped again. There is no reason for the DPF to ever be refitted, even without a DPF a diesel car will fly through the smoke test.

Cats have been fitted to petrol engines since 1992, and only now 20 years later has it become testable. it will be many years before DPF's become testable, and by then your car will no longer be on the road.

Yeah, I hadn't forgotten about going back to the standard map (one of the plus points for Shark's switchable option. And good point on the cats!

I am only going to say one thing about JBS in chesterfield. A quick google will show you a lot of recent negative feedback with regards to their workmanship.

Sorry, I did this, but apart from one person posting something into a consumers forum about a manifold, and loads of forums with what looked like dedicated areas for JBS, everything I saw seemed to be high praise. Or did I just miss something?

Both to be honest. On the legislation side, having seen VOSA declare that anything that originally had a cat now needs to have one. On the resale side, I know people get put off when things like this have been done, regardless of the fact that it's the sensible thing to do, and they could well finish up doing it themselves!

But perhaps not if they bring the particulates in to the test (is that the difference between Euro IV & V, or am I way off the mark with that?)..... And then you'd have to buy a new dpf, which is significantly more than getting a replacement link pipe at the same time as the remap.

I know it's unlikely, but I'm just being really cautious about it.

It all sounds a bit " What If and But's" I can understand you thinking in the long term but if it was " If's and But's " about every thing that might or might not happen nothing will ever get done.

Hi all,

Just a quick update on this. I decided to go for AMD, with the new link pipe.

What a difference it's made. Power is now up to 210bhp, with the torque up to 336 ft/lb, fantastic.

The pull from the engine once it hits about 2200 revs is just phenomenal, and has actually almost been problematic with the cr@ppy state of the roads over the last month or two. I've even had the traction control lighting up when doing a 4th gear/65mph overtake.

And the other bonus is, about +5 mpg!! Amazing - I've had it up to 50mpg on motorway runs, and still get 45mpg on spirited country road driving.

Downside is that with 70k miles on the clock, my clutch now seems to be going :-(

Bit more research needed on that one.

If you are thinking about having this done, just do it. The results are well worth it.

Nice result, I'm glad you went for it in the end, all the advice I was spouting out and I still have my DPF fitted!

A couple of questions, would you be prepared to share roughly how much it cost, and secondly have you noticed any smoke?

The 5mpg extra is a real bonus, my vRS is used for pretty much all motorway miles. I currently average 48mpg which sees 520 miles per tank. An extra 5mpg would equate to an extra 50 miles per tank of diesel or a 10% increase in fuel efficiency!

That extra power will put extra strain on the clutch, but it is likely to hurt the DMF (Dual Mass Flywheel) too.

Hi Silver.

No problem on the price, as it was about £800. More than Shark, I know, but it does mean I still have an intact DPF should it ever be needed again. Also, AMD in Essex were a lot closer than Shark.

Interesting that you're getting 48 - I never really got mine past 45 before the remap, and only see 50 if I keep the speed down a bit (70-80 rather than 80-90). Have you already had a remap done, but kept the DPF?

I've seen smoke a few times, but only when I hoof it, trying to upset flashy Audi & BMW drivers. That suits me fine though, as it lets them see they're getting thrashed by a diesel

Cheers Wigster, always worth knowing if when mine packs up!

The only reason I manage 48mpg is because 70 to 80% of my daily commute is between 50-70mph, a long nice steady run.

Glad you got sorted in the end, you sound a happy chappy :sun:
