Ha - I shouldn't be reading this sort of stuff, it makes me hot and twitchy

the problem i was getting with the Mpower app was it was starting the timer as soon as i clicked the iphone, not when the car started moving. ended up getting bad times :(

So, the results so far indicate more drivability, more fun and more MPG.

Is it correct to understand the change/remap has made the Yeti 140DSG more economical by around 5 MPG?

If so, an average annual milage of 12,000 miles would mean you're saving around 34 gallons of fuel, which at 6 pounds a gallon is over 200 pounds...

...and if fuel goes up to 7 or 8 pounds a gallon as some believe it will soon, then the savings become greater.

It sounds like a great upgrade.

When the DPF was taken off, how did the car computer not know it was missing?

yes, yes and yes. And yes!

it certainly appears more economical around town. It did 44mpg according to the maxidot last night, going all the way in to Fulham, across to the Old Kent Road and back again down to Croydon. It never made it over 40 before on a journey like that before. Traffic was reasonable light for most of the journey-I didn't leave home until 7.30pm!

But as with all diesels, a short trip of 1-2 miles will return 20mpg -as expected.

I'm not sure what my mileage is going to be. Estimated on 15k, but was up to 30k average aft a month of ownership.

dropping now though....down to about 21k.

I didn't have my DPF removed, but Bahnstomer is having his removed. Sounds painful

Mike

Thanks for that.

Wow, so you got 5 more MPG and with the DPF still on!

This will be very interesting to see the performance and economy figures from Bahnstomer after his Yeti DPF removal and remap... (I hope he tells us how the computer is tricked into thinking the DPF is still there!)

Well done Mike on your bravery of the engine remap and with sharing the results with us. Thanks to you, I'll definitely be doing the remap whenever I get my Yeti.

WELL; I eventually visited Ben @ Shark Performance yesterday for my Remap and DPF removal, brief details of which can be seen here;- http://briskoda.net/forums/topic/186821-snow-monster-cr140-tdi-dsg-remap/page__st__20 , and I had a very enjoyable fast run home last night.

The performance seems to be very close to my mapped Octavia vRS TDI pulling 205bhp! Certainly there is noticeable acceleration on the motorway whereas before Kevin would merely gain speed. The gearbox has already learnt to pull a higher gear with the extra torque available, at least it does not change down at the slightest opportunity, and I even executed a couple of A-road overtakes very comfortably that I would shied away from before.

I did a little performance testing en-route to work this morning.

I have a long uphill M-way entry slip road a few miles from home with the entry off a tight roundabout and have, over the last week or so, done some acceleration runs (using my mobile phone as a stopwatch and looking at the speedo; not hugely accurate but at least indicative) over 30 - 70 mph in 4th with an average time of 19.5 secs. Several runs done this morning with an average time of 14.75 secs. An improvement of 4.75 secs.

Kevin is running very smoothly, with gearchanges being smoother than before. As well as the clear increase in torque the 'top end' has improved noticeably. Previously there was little point running above 3,750 - 4,000 rpm in 4th or 5th as the rate of rise in engine revs dropped of. Now; there is a strong and steady pull to 4,500rpm and beyond.

Overall I now have the car I'd wanted in the first place; a CR170 with DSG (albeit it feels like its pulling 185/190bhp for sure; perhaps a tad more).

Wee hee!

That sounds like a result!

Did you sit anxiously watching Ben's soldering iron fiddling?

He is a top bloke for sure - and one who I'd trust 100%

What did the DPF removal entail?

Didn't watch Ben at all. I had my Laptop with me, logged into my work PC dealing with e-mails and 'stuff' all day!

DPF removal was straight forward if lengthy. Disassemble front sub frame, heat shields, all connections and remove DPF with front half of exhaust. Open DPF up (with a can opener?), break up and remove the sections of the ceramic filter (loads of dust); weld the opened section back in place; refit DPF/exhaust to car. Takes around 4.5 hours.

Afterwards it looks no different to OE spec except, if you look closely at the side of the DPF that is up against the engine block, you will see the weld where it has been resealed.

PS> Had Ben look at my dash/MFD and just got him to add 'sweep of rev counter/speedo needles on start up'.

Nifty little mod.

That's great news Bahnstomer Now you do have a vRS Yeti. All you need now is the flappy paddle MFSW.... Kevin will now be quite a bit quicker than Elsie the Helipad.

Bahnstormer,

Good write up, will you be putting Kevin on a rolling road to see what figures he is making?

Sounds extensive. As merlinman said to me over a tuning box "this could affect your warranty".

John. LOL

It's not as involved as it seems; all straight forward spanner work, put can opener and welding torch.

Yup; it probably will affect my Warranty.

Except I now haven't got a DPF to cause a problem that I will call upon to be fixed under warranty.

Rockhopper,

Kevin is mine; not Rockhopper's.

No immediate plan to RR Kevin; might do one day though.

Removing the DPF is a kind of retro-environmental procedure. Hopefully the remaining materials were disposed of responsively, as they contains heavy metals, which should not just be chucked anywhere.

What I do not understand ais that if you wanted 170 CR performance, why did you not buy a 170 HP Diesel in the first place? Except that you could not get it from Skoda with a DSG, you would have gotten the appropriate high speed additional modificatins in the bargain, such as much larger brakes, larger exhaust and bigger turbo.

With no DPF will it pass it's first MOT?

Will one need to be retrofitted?:wonder:

Materials were put for recycling by the garage.

I wanted the CR170 and needed the DSG in a small/medium SUV. Did not want to go outside VAG group. Tiguan only has DSG with CR140. Audi A5 has CR170 with DSG but costs £10,000 more and besides I don't like it.

Only option was to get CR140 DSG Yeti (which is the car I wanted, having had an Octavia vRS TDI prior) and get it remapped. I have, on taking delivery, upgraded the brakes to CR170 spec with 312mm front discs so now, to all intent, have a CR170 DSG Yeti.

Does that make sense?

Not an issue.

MOT only requires a 'smoke test' and any well driven/tuned diesel will pass this.

There are quite a number of older Octavia vRS TDI (and no doubt other make/models; there was a 56 plate Audi A3 2.0L TDI in with Shark yesterday) running around DPF-less that have, and will, passed their MOTs.

Plus, don't forget a majority of diesels that are more than 3-4 years old will not have a DPF, as it is a relative recent innovation, and they all pass their MOTs.

I didn't know that .

I assumed that the latest diesels with DPFs had to meet more stringent tests.....

Nope (not yet at least).

So, any point remapping a 110 SE? persuade me!

Had my old Berlingo remapped tomuch acclaim(betterooomph,mpg even towing a brick of a trailer?

Anyone an idea of cost? improvement of 10% 15% 20% on output?

Except that the dpf is there for environmental reasons. If anything halts the progress of diesel engines, I think it will be the dangerous particulates.

They do very soon, according to my MOT tester today.

There is to be a stricter test for vehicles new enough to have a DPF.

Apparently it's because people are removing/bypassing them and the particulates are bad for air quality and human health in built up areas.

Plenty of point; proportionately more of an increase in performance than a CR140, simply because mechanically i.e. turbo, injectors etc. they are identical. Its simply the map of the CR110 is a throttled back CR140. Therefore, in theory, you can get the same eventual output out of both engines.

I believe this has been under consideration for some time; we'll all have to wait and see.

Octygone had his remapped by Shark and it now flies. Around the 150/160bhp mark with improved economy
