Rank Taxi Two. The Octavia - Back from whence it came..01/09/24

[SiC]

On EDC15 and EDC16 ECUs (Bosch diesel ECUs), VCDS can extrapolate the mileage from the average speed and time. Often when clocked this isn't changed. It can give an indication if someone has been fiddling with the odometer previously and a rough idea of what the true mileage is.

It's on a separate button in VCDS (applications) rather than an option in the ECU directly.

I think using a MK1 eyeball is sufficient to say this is tiert 😂

I'm just intrigued by how much!

This shakes like a dug shitting razorblades if you apply the brakes with vigour..

 

It's pretty obvious that an overhaul of the front brakes including :

stripping and cleaning the calipers/sliders

replacing pads

replacing discs

new fluid

 

would have a most advantageous effect upon retardation of the vehicle.

 

with this in mind, a key element was identifying what size of disc was fitted to the front of this tub.

As it's a taxi special MK1 (1U code) built 5 years into the MK2 Octavia build time, details are a bit sketchy. I was fairly sure it had 280mm front discs, but it felt prudent to review before parting with actual cash.

the plan was simple - pull a hubcap, remove a wheel and measure.

The reality was somewhat more taxing..

The hubcap came off ok.

The first wheel bolt was tighter than @sierraman - taking the bouncing of all of my 10* st to loosen it.

The others were no better, but eventually, 80% loosened off ok.

The final 20% required a specialized approach..

Despite looking a bit sketchy, this worked a treat .

Wheel off, and 280mm discs confirmed.

The decision was taken to clean the wheel bolts and apply a little copper slip before tightening them back on by hand - thereby ensuring they can be removed using the wheel brace if needed.

Similar was done on the other side, so now I need to get the discs ordered up.

 

Additionally ,  the tank was filled after 696miles. 

Anyone want to guess on the MPG?

[sierraman]

You cheeky twat 🤣

[beko1987]

70mpg like any other diesel shitbox surely?

Anyone else any guesses?

[sierraman]

63mpg

[loserone]

27mpg?

 

I drove it up on fumes+£10, so probably pretty high

[Dave_Q]

Somewhere between 45.2 and 48.68 mpg depending how brave you were in running it down to empty.

I had to luz 10L into it to get to payday. It's all included in the calculation.

 

The light works, but it's still only a 55L tank😜

[Jim Bell]

It's absolutely commendable that such improvements have been made on this old tub. It looked fit for the bin when you got it and it'll be not far off a wedding car before you've finished.  

 

[jonathan_dyane]

49mpg

I somehow decided it would be a 70l tank.

As such I revise my guess to 52.58mpg

[EyesWeldedShut]

69.6 mpg for me in the sweepstake

[Supernaut]

51.3mpg

Shit I didn't realise it was a sweepstake. I hope the prize isn't the car?

I don't think Dave Q would deserve that luck

No - 58 tickets in the roffle to give you a sporting chance

Similarly I'm amused and surprised and now quite glad the scrapyard told me to fuck off.

 

Sorry about the wheel studs, that'll be bunny's tyre fitting trainee again. Is the tyre a landsail?

@Dave_Q !

 

Well done.

 

I checked the tyre pressures when fuelling it up - 22-24psi seemed to be the ballpark.

They're now at high 30s so 60mpg can't * be far off😜

Cheers man. It's cheap motoring, and actually a comfortable place to be as long as you account for it's age and miles. I enjoy things like this that don't need too much effort but end up with a useable car.

I expect similar should I ever scrap it😜

 

No worries re the wheel bolts - better to find out now rather than on the hard shoulder! 

Aye, land sail(ING right into the hedge)

Watching with envious eyes... I absolutely love Mk1 Octavias, so much so that I've sourced and supplied two of them for my younger brothers (One each)

Andy has the doom blue number fitted with the legendary ALH VE TDI 90 that's sitting at around 220k, and young Tommy has a povo spec SDi in silver. That one's a relative baby having covered a mere 120k.

Here's a shot of them both sat on my drive next to a giant pile of rubble awaiting an oil change last year (Both are still in regular daily use)

Yes Sir. The excitement was exciting 😁 

[320touring]

This tub continues to give sterling service.

 

Still not done the front discs. Instead it has...

Done some off reading at Twixfest 

Held pies that won me brownie points 

Been considered the most improved car 

 

Set up it's own NEW CAR POOJA (the Hindu car blessing ceremony)

 

And. Had a weight taken off it's back axle.

All this was in the boot ( plus enough rubbish to fill a full black bag!)

We're nearly at 400 miles this tank and all seems well.

 

Been a good buy this.

[320touring]

Today @Lacquer Peel turned up at the unit with an exceptionally fun bit of kit..

This is a windows XP laptop loaded with both MPPS (ECU reading/writing software) and VAGEDCSUITE (map editing software).

At this point, hopefully @Dave_Q knows what is afoot.

Time, ladies and gentlemen for MOAR BOOZT!

We got the software to connect eventually after a bit of faffing with USB ports and the cable.

We got in and started our 1337 Haxorz 

 

The software found the ECU ok and read off the file. This was safely stored on the laptop and on a USB drive. (FORESHADOWING)

 

A new map was created with a modicum* MOAR boost and fuelling.  Numbers in the order of 140bhp and 320nm of torque were seen on the performance projector..

 

Giddy with excitement, the new map was dispensed forthwith down the silvery cable of goodness.

Finally it was done. 

 

Time to start.

 

Duggaduggaduggadugga...

Fark.

Maybe the battery voltage is low

*Attach Polo SDI for charging*

Duggaduggaduggadugga

💩💩

Time to roll back to the original map.

 

No bother!

 

 

ERRRR. Y U NOT WRITE FILE TO ECU?

 

time for plan C

Despite being shown the above, it was still recalcitrant.

We tried removing the dash cluster fuse (sometimes this helps). But not this time.

Reinstalling the software was tried

Changing the mapping cable was tried 

Battery disconnection for 30mins was tried

Ignition on for 30 mins was tried

NO DICE.

 

At this point, I prepared the XJR as an alternative way to get home, and was prepared for the visit to the fuel station required.

 

All the while @Lacquer Peel remained calm and focused on problem solving.

I just had a maniacal laugh 😂 

Until we alighted on an interesting idea

 

The maps that had been created showed up as "VLC media player" files with the .bin extension.

The original file was only showing as "file".

We altered the laptop version of the original file to have a .bin extension.

This loaded up ok.

And it RAN😄

 

I'm home now, and have the laptop here to make another map😂😂
