Hi guys,

After having a few fabia vRS's 3x Silver 1x Red, selling and eventually realising not much can replace it for what I need, reliability, economy and simple ease of driving for a daily driver, I have come back to own a nice but no where near perfect black fabia vRS. I have to add, black seems to be by far the best colour, but does attract unwanted attention.

My previous vRS's have been 04, 54, 05, 06 so two ASZ and two BLT, all 4 gave good MPG, I do a motorway drive every morning to the gym, which is around 14 miles, I know this isn't really enough time to warm the engine up, but, all 4 used to easily average over 50mpg average by the time I stopped, slow cruise 50/70mph depending on variable speed limit.

The current car, struggles to get up for 40mpg. Also around town its very poor. Highest I have seen it on a run is 45mpg, over 60/70 miles, doing 70ish on cruise.

Previous vRS's from £20 diesel current prices, as it wasn't too long ago I have the silver 04 and red 54, I would get 120-145 miles. Thats from the petrol light coming on. The currently model just about gets to 100 miles. Im able to get 90+ in my 06 civic type r, and as you can imagine thats with some brisk driving.

It has been serviced every year or 12k, last one was only 5/6K ago. Also had a new turbo around 10k ago. Car is currently coming up 100k

I will be looking to service the car anyway, for peace of mind, TPS parts, I will also be looking at cleaning the EGR valve on the weekend. I have added wynns injector cleaner over the past two trips to the petrol station as well.

VCDS Scan showed no faults what so ever.

Any advise guys, so for its not doing any benefits for my wallet

Goodness! and i thought mine was performing poorly :-/

I get 430 miles to a full tank and that's if I run it right down into the red until the trip computer says 10 miles left.

Id be interested to see what the problem is when u finally get to the bottom of this as I keep reading about others doing hybrid mods and still getting over 60 mpg when mine barely ever made 45 on a run even when it was standard :-S

me too as mines a little underperforming at the minute aswell

Poor MPG & drop in performance are common symptoms of a dirty EGR valve, take off the top intercooler pipe and have a look inside to see if it's caked up.

I use Wynn's Diesel EGR 3 cleaner at least once per month as a preventative measure to keep it from getting clogged up, although the EGR fitted on mine isn't the original.

EGR looks like the first thing to try then, my only issue with the EGR cleaner is, once sprayed, where does all the gunk go? Does it dissolve? Or would it be better to take the pipe off and wash it out?

I got a feeling that the EGR hasn't been cleaned, or replaced in the 100k its done.

Can't comment on the performance to be honest, as I don't have the others to compare it too at hand, I thought it performed quite well, I will be well impressed if it gets any better without the remap, soon to come

The aerosol cleaner won't do much good on an aged 100k miles EGR valve as it only removes the loose sooty deposits, they get burned in combustion and come out via the exhaust. Best bet is to remove the unit to give it a thorough clean, you'll be able to do a much better job and there won't be any big chunks breaking off into the engine.

Sorry to hijack.

Anyone know of a guide, pref with pictures, for removing the EGR?

A faulty MAF can also play havoc with fuel consumption.

my egr has recently been clean and i still have felt a power loss and mpg not as good around 60 miles to £10 which i thinks bad for a diesel???

what about brand of fuel, supermarket fuel that i've run mine on i have found that i get less miles over a tank full compared to branded fuel shell/ esso, i haven't run mine on bp yet. 40-50 mile difference all adds up.

Winter diesel and cold weather will have some effect at this time of year.

If you work out mpg instead of miles to £10 it will actually have some meaning too!

Has anyone got the link handy to read MAF values on VCDS?

60 miles to £10 doesn't seem to bad, current rate im getting 50, which is pathetic, i've left the vRS at home, and im out in the Type R.

EGR will be cleaned saturday, along with a new air filter, genuine filter, not a aftermarket, as all I can see is horror stories on the forum regarding the oil causing problems, unless anyone can tempt me to a decent aftermarket air filter?

There's no point using anything other than a normal paper air filter on the diesel vrs. Also, when was the fuel filter last replaced?

Is there a guide on removal of egr?

I've never had an average over 42 mpg, to me it seems about right for the type of driving I do, it still pulls like a train though

Might be this : http://www.autospeed.com/cms/A_112521/article.html

...Or many of the other suggestions previously made. I s'pose an inlet air leak might also cause issues and might tie in with the turbo having gone pop...

So many people having issues after a belt change on this engine. Skoda need to come forward and admit just using the looking tools does not guarantee optimal timing. They need fine tuning after a belt change something dealers and garages disagree on. The reason for this is the only real way to tell if the timing is correct is to take it for a drive and log the timing with vagcom. They do not want to do this with every PD engine customers car so get it in tolerance and leave it there. I bet in Germany they fine tune the timing, I want to know. Bodge cowboy garages we are subjected to in this country are getting on my wick. If you think your timing belt was incorrectly fitted and adjusted on a PD engine contact trading standards and at least get your money back like I did. With vcds go to engine block 4 measuring blocks and check the syncho angle. Should be close to o.o. .

I made a mistake and wrote I had a BLT engine, but according to the cambelt cover I have a ASZ engine, must have been one of the last ones.

After a brief EGR clean, I belive theres a massive improvement, currently have not seen under 50MPG average mixed driving.. 96 miles from £20 with around 120 miles left on the range. Will post full results having topped up a few times.

Will this be the same 0.0 on a 1.4 TDI engine ?

DB.

Ok, results from the first £20.. It was just under 14 Litres of fuel. And it come out with 139 miles till the light came on.

Now that doesn't seem bad to me? However my average seems to be better driving around town, rather that on the motorway, driving at 50/60/70 on cruise doesn't really make over 50mpg, but driving around town I can make 50mpg..

Also a friend of mine has a 54 Fabia vRS, same engine, same route on the motorway, he gets a staggering 63.3MPG! What on earth is going on?

Have you looked into the MAF?

Get some readings with VCDS.

Faulty air flow readings can play havoc with fuel consumption.

What section in vcds should I be looking in, and have you got what the readings should be mate?
