Been given a Roomster Scout today (actually quite nice, VERY spacious inside and getting used to the weird looks!)

Not sure what output it is but the CR TDI is unlike any other diesel I've driven, no power the bottom of the power band, above 2300 ish? the power starts to kick in so you find yourself revving it more than I thought you'd need to

On a 35 mile journey home it only averaged 53mpg on the motorway and its extremely gruff (Although i do like the sound of a derv personally)

Quite glad I picked the TSI, seems more punchy, similar economy (I get about 47mpg) and A LOT quieter (can't hear it on tick over)

Also when you change gear theres a weird grumbling noise... hard to explain!

Should have monte back Thursday

It is possibly a 1.6 (put the reg into the "fast finder" on ECP's site and it will tell you) as most courtesy cars are 1.6 or smaller.

I currently have a 1.6 MPI (petrol) Octavia courtesy car and it sounds just like 'your' Roomster - noisy and gutless, my CR170 is MUCH quieter and smoother!

Dont know the reg and canney be assed to go outside and check lol :(!

Does seem very gutless for a derv though but it has only done 143 miles lol, complete contrast to the TSI thats very punchy and refined... Has a nice growl to it too!

I dread to think what the PD engine was like if people say this is refined lol

I love the PD, loads of power low down where you need it, some say it has too much low down and runs out of steam quickly, but I never found that in the 3 1/2 years I had mine, I do miss my 130PD, the CR170 is much quieter and the power is more linear, some say more petrol like ... just nothing like a 1.6 MPI petrol

Its strange, the TSI drives like a diesel to me, no grunt from 1000-1500 revs... 1500 comes along and woosh off you go, power up to the red line!

This derv drives like well god knows, no power for AGES then you get a little bit of a burst and.. next gear!

I've heard the MPi is a bit erm... naff :p

I love my PD , great driving school car, I could sell them to all my pupils as they love it to bits. Extremely easy to learn in as the power low down is incredible, very forgiving of wrong gear selection, just grumbles to give you an idea you need to check what gear you're in, and as for manoeuvres it just trickles along with no accelerator needed.

Been looking to change though but the new 1.6 cr i drove seemed a lot slower to me, the PD just surges forward and is so easy to live with.

Maybe time to go back to petrol?

Get a TSI, its a truely brilliant engine! Doesnt feel like a 1.2

I did love the three PD cars I had but preferred the CR vRS Octy and my current TSI vRS Fabia blows them all away.

Next time it'll be a TSI Octavia - provided I'm not commuting 20K a year. Though I hope by then to have completed my current certification I'm working on, hopefully I'll be on a nice fat "daily rate" instead :-D

To be fair, even in a brand new car the diesel fuel economy is almost 25% better...

Hello Adam, you have noticed what quite a few others have noted. The CR1.6 is different to previous diesels. It is a shorter stroke engine which reduces piston speed for any given rpm. This has several advantages but I won't go into that here, you may know that stuff anyway. But it does mean a slightly different driving technique ought to be learned to get the best out of it. It's no good plonking it around like a long stroke diesel at 12-1500 rpm (PD was long stroke as are nearly all others on the market), it won't go so well and it will use more fuel, especially in the early miles as these engines are tight beyond belief. Shorter stroke engines need to be revved a bit more to obtain good power and fuel consumption. However, once run in and that means not just doing 1000 miles, but properly bedding it in over several thousands of miles, then it's a completely different story. How the engine is treated in the early miles seems to be more important on these CR1.6's too. If not done properly it seems to affect the fuel consumption and power output for some time to come. Don't forget the 90ps and 105ps CR1.6 develops huge amounts of extra torque over the TSI engine (CR1.6 = 230nm 90ps & 250nm 105ps at 1800rpm). Frankly, that's amazing. They really fly and the TSI can't really compare for fuel or power in real terms or on paper (no, I'm not saying the petrol TSI is not a good engine - it's brilliant for a petrol). The Roomy won't be as economical as the Fabia as it's heavier and has a bigger frontal area to drag down the mpg. I would also suggest you were just not used to driving the 1.6cr and maybe it was still very tight too. Interestingly, I've noticed it's people who come from driving petrol engined cars to diesel CR1.6 engines for the first time that seem to do best with fuel and power. They never learned to drive a diesel previously and the CR1.6 is a bit more petrol like to drive, so they take to it like a duck to water. Let us know how this pans out over time. Always nice to know people's thoughts on different motors and it's helpful to everyone considering a change. :yes: Very glad you are pleased with your choice though.

I drive my tsi like a diesel due to the low down slug and I drive the cr like my old diesel due to expecting low down slug but realised I have to rev it more.

I've always found its more a question of learning how the engine needs to be worked... So its a question of experimenting until you get the right way... I'll be testing a 1.6 in a Golf on Friday so it will be interesting to see how it compares against the last 10 years or so of the 1.9 PD! EM, how do you run in the 1.6 correctly as I'll probably be getting on in due course... Can't afford these petrol thingies...

BTW I drove a 1.5 dci Meganne yesterday and was impressed with the engine, if not the car... Very flexible...

I only have 75% of the 1.6 CR engine in the Gl2 Fabia, but it's incredibly economical. Although if I wanted something more pokey I'd be very tempted by the 1.2 TSI over the 1.6 CR Fabia.

We have the 1.2 TSI DSG Yeti and even with the weight and frontal area I can get 50mph on the commute, 44mph normal driving, where my GL2 averages around 75mpg. If I was to drop down to 60 or 65mpg for a 1.6 diesel Fabia I'd go for the petrol instead for the smoothness, cheaper cost new and no DPF to think about.

If it's only about 10mpg difference the petrol would strike me as the better choice, which is unusual as I do like a diesel. But I have been very impressed with the 1.2 TSI in our Yeti. And it really suits the DSG.

Drove a dci clio very smooth refined engine, more than the vw cr tdi

I had exactly the same thing with my scout courtesy car making a strange grumbling noise on changes! no idea what it is and the dealers said it was normal...

Hi 'The PM' (love that user name, I'm even a bit scared of talking to you in case we are hacked!!!). Yeah...you are completely right, I believe about the above. Running in on these modern diesels can be a little more of an issue it seems and it's worth reading the manual. In reality you don't need to do much other than just that, and then put it into practice. But the main points to keep in mind (and actually you probably know this already) is to avoid constant speed operation ie: cruising at fix engine speeds on motorways or dual carriageways. It does nothing to bed the pistons and rings in. Instead, vary the throttle setting and load, deliberately use the gearbox more than usual where possible, don't potter around in high gears at low revs, vary the load on the engine, let the revs go up but don't over rev it or slam your foot down too early in it's life. Best to avoid economy runs...this encourages constant speed driving and glazes the bores and rings. But best of all don't think you have to drive it slowly, you don't. Observe those things and remember what you running in section tells you and it's plain sailing. You don't have to get everything right all the time but it helps overall if you do those things.

Bye for now...

Does the same running in procedure apply to the 1.2 tsi because I have one on order?

Just to add my two penneth, I've just been provided with an almost new 1.2tsi elegance loan car as my VRS build is delayed. I have to say I am really impressed with this engine, nippy, smooth, quiet, and so far averaging over 48mpg, far superior to the 3 cylinder 1.2 I've had for several weeks beforehand. Previously I bought a new diesel VRS and ran it for three years which was really good,(I appreciate it's a totally different engine to the CR), but I think for everyday driving I actually prefer the tsi.

Lo Jaxx, yep! Stick roughly to those rules (which are basically outlined in your user manual anyway) and you can't go wrong. You lot are all getting new motors and now I'm envious! :yes:

Yeah...I agree, the TSI's are very nice indeed...but I'm addicted to derv!!! I need help...:yes:

the 1.5dci lump is a peach hopefully the new 1.6dci sounds even better hopefully its going in the clio

So EM,

You have NE really worried about my fabia due in September. By October it will have done 3,000 miles all on the M25 - how can I hope to run it in 'properly' ???

diesels are better in many ways but if i was getting a petrol i would go for the 1.4tsi not the 1.2tsi whats the point

I would have gone for the Vrs if it had been A manual gearbox. The monte is just such good fun to drive especially around the twisty hilly Devon lanes.I never thought you could have such fun in a 1.2 litre petrol

No...don't worry Whitelighter. Just do as the manual says, drive it fairly normally paying attention to the things mentioned in the manual. but don't pootle along at 50-60mph in 5th all the time...it won't run in. With the engine warm, you need to get metal to metal contact between bores and piston rings to run it in. So vary the load (throttle setting) and speed of the engine (not necessarily the car). It's ok to drive on the motorway if you need to but avoid holding the throttle and revs constant for very long, vary the speed of the car by just a little too from time to time. In other word just ease off now and again to draw up oil to cool the pistons and rings and wash away the metal debris which collects behind the rings. Give the engine extra throttle now and again then lift completely off for a few seconds. Pop down into fourth gear too on occassions to completely alter the load and revs. Actually, you can if you want ignore all this stuff and it will still probably be ok. But will it be the best for power and economy, and run very quietly? No...probably not, so it's worth doing it to get that much better economy, be more reliable and much more powerful. The main thing is to avoid extremes of driving style...slogging it along at too low a revs or too high revs. You'll be fine I'm sure.:yes:
