Fuel consumption/DPF issues 1.6 TDI "Blue motion technology"

[divsec]

Hi, I have a 1.6 TDI se manual due for delivery next week. Can anyone suggest mpg out of the box and likely after 10k miles?. I'm a gentle driver but don't mind thrashing it a bit if it will help. Any thoughts about running in or is it all nonsense?

Running in? Many people will tell you you can do what you like with it, and you can - the car will still function, although maybe not to it's best potential. I am a strong believer in running in properly to get the highest mpg and output as well as low oil consumption (I had one MK5 Golf that was not run in properly and it used a litre of oil every 1000 miles and was dogged by poor fuel economy - the other 5 new VWs have been great).
Variety is the key in it's early miles (first 1000 miles) - If you can (if your commute or driving habits permit), do lots of short to medium (up to 30 miles) journeys of varying speed, moving up through the gears - being quite gentle for the first 500 miles, trying to use no more than 1/2 throttle for the first few hundred miles but don't worry about the occasional incursion into 2/3 throttle. It's not the speed, but it's how you get there. Driving around at 70mph is fine as long as you don't thrash the car to do it. Don't be too gentle, don't be too mean - neither are great for running in your car. The worst thing you can do is take it on a long journey with delivery miles and have it sat at 70mph in 6th for it's first 300 miles.

Right out of the box you'd probably be expecting an indicated 55mpg, maybe 60 if you are lucky. This could drop off a bit if you are plagued by active DPF regens caused by consistently short journeys.

Hi, just got the car today very pleased. Absolutely standard se manual. But a pleasure to drive. Even messing around, short runs and with less than 200 on the clock I am seeing 50 mpg. Can't wait for a nice cross country drive. Nice car.

Managed my first proper drive today, 120 miles cross country. Dunstable to Daventry to Banbury to Dunstable. 59 mpg according to the car. I am a very happy bunny.

I would only have seen 45 mpg on my Merv b class (rip) at the very best and nowhere near as much fun. Looking forward to a long run to Devon and Cornwall in September.

I'm surprised that a 1.6 blue motion doesn't do more mpg. I have a 2.0 TDI 170 and drive once a week from a little village near Thame to the Bristol M4/M5 junction. So probably 90 miles of M40/A34/M4, about 10 miles on the southern Oxford ring road and a few miles on country lanes. I usually get about 52mpg, the worst I've ever got is about 48mpg, and the best is a whisker under 60mpg. Consumption always seems better on warm dry days and worse on cold wet ones.

How many miles does your car have on the clock as a matter of interest?

[KeithS]

About 65K. It's nearly 6 years old, and the mpg hasn't really changed since the first few months from new. I guess I get good mileage from motorway runs, but even going to the supermarket about 6 miles away, I usually end up around 50mpg.

Thats good.

I felt my previous Mk6 TDI had only just run in at 62k before I sold it .
Nice and fluid if that makes sense.

Hey guys
I just bought 1.6 tdi. Mk7 estate. Absolutely love car, and prefer diesel over petrol. I do very rearly long trip miles, mainly commute to work every day 5 miles and 5 miles back. Yes, I know I would be better off with Petrol.
My worry is I had 2 Bluemotions in past 2.0 tdi Passat and MK6 Golf 1.6 tdi and both had egr cooler failed. Symptoms were car was first trying regeneration quite often then dpf light will come on. Driving on motorway with revs over 2k would remove dpf light and car would become normal. Only after few weeks/month glow light flash and visit workshop message appeared on mfd. Both cases were diagnosed with failed egr cooler.
Now I have mk7 golf hoping that it will be improved. After 3 days commuting to work, car started reving higher than normal on idle just above 1k. Came home turned engine off, and fans kicked in, they were running so loud, it felt like hoovercraft sat outside. 10 min later fans went off. I believe car was trying to regen and I turned engine off. Should I leave it running until it returns to normal idle? Is this normal behaviour?
