Hi all,

 

Just picked up an '08 vRS PD170 and absolutely loving it. Some years ago I had a PD130 Passat w/ remap which, when I did the mufflerectomy, really benefitted with faster spool up, slightly more turbo noise, and a slightly deeper note.

 

Has anyone done this on a vRS PD170 - what are your thoughts? Hoping I would get the same benefits, not expecting anything dramatic or sweet-sounding, but it was definitely noticeable. From a Youtube test video, A SEAT Cupra TDI made 7 bhp and some torques when dyno tested (x3).

Nevermind the numbers though, on my PD130 it definitely had a more 'willing' character, and that was worth the £60 to lop it off and replace the missing section.

 

Cheers!

 

 

PD 170.  So it's a BMN engine.  Before thinking about the exhaust, I'd advise investigating the intake.  Does it have the original plastic intake manifold with the flaps?  If so, you'd be well advised to swap it for the PD140, BKD manifold which doesn't have the flaps.

The plastic flaps stick and break up and can get sucked into the combustion chambers.  Also the spindle bushes wear and leak boost.  I found that changing to a BKD manifold produced better performance and drivability and much better fuel economy. 

Hi Schtum, indeed it has the plastic intake. I see Darkside do a kit to replace: https://www.darksidedevelopments.co.uk/products/ppd170-used-bkd-aluminium-inlet-manifold-conversion-kit.html

I will get that ordered soon.

 

While at it, I guess it's worth an EGR delete + EGR cooler delete. Will this throw check light that would need mapped out?

 

Assuming I have the BKD intake in place, what would you then say about the mufflerectomy?

 

FYI - RARB is on the list. Not sure if worth the money and effort, but I'm also looking at a front strut and the chassis brace.

Not sure if this car is mapped - might consider a basic map, but nearing 14 years old with 152,000 on the clock, I'm concerned I'll end up putting this beyond economical repair.

 

Any and all advice for a new vRS PD170 owner is very much appreciated. My other car is an offroader Disco 2, light mods to exhaust and engine.

If it still has the DPF in place, I'd be wary about deleting the EGR.  They're both part of a system and the EGR is involved in DPF regeneration and removing the EGR will also increase the particle load in the DPF.  

You'll know better than me about how removing those parts would affect the N.I. equivalent of our MOT test.

 

I'm not a fan of emissions equipment removal as I don't like driving around leaving a cloud of smoke behind me.   I did remove the cat' on my old Mk4 Golf GT TDI after it broke in half.  It was remapped from 115 bhp to 150.

Removing the cat certainly allowed it to rev much more quickly and it would hold its own across country with my remapped Mk5 up to c. 90 mph. 

 

As for remapping, my BMN was an 08 Mk5 Golf GT Sport that I bought new.  I had it remapped by Angel Tuning 

when it was c. 5years old and with 50k miles on it.  With the plastic manifold with broken flaps still in place, before I learned about that, it made 200 bhp and 330 lbs-ft on a local well calibrated dyno.  Needless to say it went

even better after fitting the BKD manifold as supplied by the Darkside guys.

I believe it does have DPF but I'll check the code sticker, NI regs, etc. Thanks for the extra info!
