King of the Rank! Skoda Octavia- Fresh from its victory at Crail!

Aye fuel filter sorted it.

Do you not carry a spare with you then?

When I ran veg oil I carried a pair in the boot.

A spare was in the car on sunday but the biblical rain was not making changing it very inviting!

[garbaldy]

Ah right just have to carry an umbrella in your toolkit as well.

Umbrella can only defend from rain in 1 direction..

 

This was coming from at least 5

[320touring]

Well that's a good lesson as to why we change fuel filters before 190k lol.

 

We back in the game for next season you think??

that depends on MOT!

[320touring]

Joy of joys we had an FTP tonight fue to a sticking air valve.

 

Looks like a simple waggle resolves it.

 

My reward for getting the RAC out? more shitty fuelling and a refusal to pull properly.

 

Think there is either air getting in (possibly at filter) or the veg I'm using is not filtered correctly (likely my fault!)

[Lacquer Peel]

Air valve?

[320touring]

Air valve?

like a stop solenoid hingy up by the egr..

 

whitever it it, it needs to be am ooty furtae start

[Lacquer Peel]

I know the thing you mean, does it need a good clean? The EGR, inlet manifold and associated bits on my Octavia were grim, will treat the Caddy to an EGR delete and inlet manifold clean soon.

probably could, but that would involve caring;)

 

sorting fuelling is first thing then take it from there!

Missing most of the car there...

[Dave_Q]

It will be the anti-shudder valve, it only has 1 purpose which is to stop the big shake you get when turning off an older diesel.

 

I would suggest binning the whole thing including egr, obviously this may cost more $$ than you're willing to spend right now to get a delete pipe, unless you know a tame welder who could fab something up?

If it makes it to friday evening and back home, I may consider having a look/cleaning it out. the map has the egr switched off, so once cleaned it should pose little trouble.

 

anti shudder valve aounds like the current culprit, but fuelling is main issue. May try new o rings on filter later

[Lacquer Peel]

Since this has turned into a general VAG TDI fault finding thread, what causes the engine to shudder at very low revs sometimes? I'm sure my Fabia SDI did the same thing. Is it the accelerator sensor?

[Dave_Q]

Not changing gear?

 

I've found with the last few dizzlers I've had that they give a fair judder if trying to do say 30mph in 5th which will be 1200rpm or so.

 

I think I've decided that it's not really a fault and to just use a lower gear when it happens.

[Lacquer Peel]

It's not like a transmission shudder, it does it even when the clutch is depressed.

[320touring]

Mine tends to shudder more when on a map than stock - i think it may be due to too much fuel for the load - like am old XUD that gets grumpy

[forddeliveryboy]

Can't remember if you've had the sender unit out of the tank yet, but they're very restrictive for veg supply. I think the Canadians had to mod them for running on pump diesel, so bad is the restriction - I did mine ages ago and throttle response was much crisper. If you're doing much full right foot on veg then even a parsimonious Octy would do waaay better with a bigger supply line, or you could run a second one like I did on a 5-pot Audi.

Interesting thought- well worth a swatch at the weekend!cheers

[forddeliveryboy]

With the wick turned up, derestricting the strainer and enlarging/doubling up the line should feel like you've plumbed in a second, small turbo. What veg% are you running?

[dome]

Aye, I did the sender/strainer mod on mine after it got clogged up. Pretty easy but a bit messy...

[320touring]

This fucker was stalling and not pulling right at all. ditched it and have the 172 instead.

 

work is shit too. winning!

[320touring]

Changed the valve on the filter for one on my brothers car (which had had new seals etc)

 

fuel is still frothy.

 

cant get the top screwed off the tank pickup/level sender.

 

train to work tomorrow then

[Lacquer Peel]

Balls. The ring that holds the tank pickup can be a bugger, use a big flat head screwdriver and a hammer to get it turning. I haven't broken one yet.

the screwdriver I had was actually cutting into the plastc rather than turning.

 

Its 4 weeks til mot time.

[Lacquer Peel]

Dislike.

[dome]

At least you've got your brother car to rob bits off. Stick at it, you'll get there.

Rapidly going aff it tbh. the whole fleet (save the CLIO!) are borked.

Hit it on every tab, use a blunt old chisel and try try different hammer sizes. Then tap it hard in the clockwise direction similarly, then reverse. It's all plastic. If it's still stuck fast, cobble a tool together with a section of pipe and attach a lever.
