Hi all! Long time user, first time poster here… in need of your wisdom & insight!!

I’m thinking of replacing my ancient but serviceable Fabia Mk1 1.4 (51 reg) with a Mk3 Octavia Scout & would welcome a heads-up on what to be wary of & to look out for when sourcing this car (I’ve had a bit of experience over a long lifetime but not owned 4x4 b4!).

The specific version I’m considering is an automatic 2l TDi. I need the 4x4 ability to navigate the country roads here in Wessex which are prone to flooding/mud/ice etc in winter.

What are the issues owners have contended with, either mechanically or electronically?? Is an auto as good an option as manual in this car (need auto for long motorway journeys!!).

Any input gratefully received!!

I've just bought myself a mk3 facelift Scout. Here are the things I've found through research and what I've looked for when buying

This is my 2nd mk3 Octavia with a DSG, I'd not go back to a manual gearbox & this is our 2nd Skoda with the Haldex system (1st Yeti 140bhp manual), I live in the Peak District and tow caravans and a horse and found the haldex to be very effective in muddy/snowy/icy conditions but have always run Michelin CrossClimate tyres too (no point in having the haldex system if you don't have the tyre quality to grip).

• Euro6 Diesel engines only have adblue from 2018 onwards (approx) but all years have DPF's

• Service History for me is an absolute must. One thing to note is some cars will have a service book and others just have a print out, my car came with a print out from Skoda, don't be afraid if you only have a print out, contact Skoda UK and ask for Service confirmation

  • DSG - Pre 2018 I believe you have the 6speed DQ250 (mine has this on a 2017 plate), newer ones I think have the DQ381 7speed?

    • Check for servicing of this DQ250 - 40,000miles / DQ381 - 80,000miles)

  • Cambelt - 2l tdi Cuna 184bhp engine has varying recommendations usually 4-5years or 60-80k, if its been changed check for the water pump being changed too (I'd always ask for this to be changed at the same time)

  • Brake fluid - initial 3year then every 2 years

  • Haldex - 30k or 3years

• Tyres - What have been fitted can tell you if little faults will have been fixed (in my opinion), how much tread is left? if less than 3mm budget to replace

• Brakes - how much of a lip is there on the discs, how much pad is left? if well worn budget to replace

• Check panel gaps and sign of paintwork

• Scouts are not off-roaders but are very capable, with that in mind check underneath for damaged sills/broken panels etc

Take it for a good test drive, there should be no knocking, the gearbox should be smooth. Check everything works (windows/sunroof/radio/android auto/aircon/heated seats/lights/central locking/check for spare wheel or tyre gloop kit).

If it has a panoramic roof look for stains on the roof liner & damp foot wells, the front drain holes are easy to see and clean but the rears are a little more awkward

Known Issues

• DSG - Error service: leave vehicle only when selector in position p. I'm not sure if this is limited to the DQ250 or not but both of my mk3 Octavia's have had this, it doesn't affect the drive but can be costly to repair

• Panoramic roofs - drain holes become blocked and leak into the cabin (check rear and front roof liner/footwells and boot floor)

• DPF - not limited to the Octavia but if you don't do enough higher speed miles this can block and cost a lot of money to replace

I'm sure there are many more known issues but you can become too fixated on them, every car has known issues!

Don't be in a rush, take your time when looking, I've been on the lookout for the last couple of years since we sold our Yeti & it paid off, our Scout has had a very fastidious owner, @64k (2017) it has had Cambelt & waterpump / x2 DSG / x3 Haldex / x2 aircon services, it even came with all the accessories that I would fit (Skoda rubber mats/boot liner/spare wheel). To me all these little things show it has been very well looked after, I also saw it before dealer prep as it came from the previous owner.

Just to wet your appetite here's mine

On any TDi check check coolant expansion colour (should be bright pink). Look for any signs of any debris in the tank.

VW used a bag of silica beads in the expansion tank to "prolong" coolant life. The bags split and blocks the heater matrix. It's well documented on here. You get cold air on the drivers side and warm on passenger side.

Expansion tank has the word MIT SILIKAT on the outside. It can be replaced with one without the silica bag.

My blocked heater matrix for this issue cost me £600 to replace and flush the whole coolant system out twice. Mostly labour.

DSG is very good to drive. servicing every 40k miles is circa £2-300. Oil and filter change.

I have a Octavia Scout MkIII 2015 and what Paulski mentions happened with my Skoda. The mechanics tried to flush out the system and replace the coolant but informed me they could do so completely and it was still a bit gritty. They assured me the heating would work which it did. However the heater fan is now about 40% less powerful (not sure why) and the heating is not nearly as high as it used to be. Sometimes I can hear strange whooshing draining noised when I stop the car.... something is still not quite right even though I spent ££££ !!

oh FFS. I'm assuming that the Silica bag in the header tank split in that case....

You need to do multiple flushes - typically between 4-6 flushes to get rid of the silica beads which have probably blocked up the heat exchanger in the cabin (low point on the coolant system). Typically, the system needs to be flushed with a high pressure hose or under pressurisation.

The coolant then needs to be refilled using G12evo coolant after the final flush and then the car needs to be electronically 'burped' to get rid of all the coolant air pockets.

thank you for this - yes. I wish now that I had insisted they flushed the entire system properly rather than accepting what they told me and paying them for a job half done/badly done. I'm on the look out for a mechanic who's prepared to do the job - as well as take the money for doing it!

Find a good local VAG specialist in your area. Don't go to a main Skoda Dealer.

Good tip. Just found a couple in my area. Going to call them about an ABS wheel sensor (how to test with a multimeter) and gauge how good they are by their response! Thanks again - appreciated.

Refilling of coolant system is best done under vacuum, where the system is pulled down under vacuum and the new coolant is sucked in from the container.

Additionally my indie who I only trust my car with, told me after they changed the heater matrix, using their diagnostic software the coolant pump is set to cycle automatically in order to purge out air for 150miles. They use ODIS which is main dealer VW group software for diagnostics. I am sure that garages with suitable diagnostics, Launch, Topdon etc have the ability to enduce this too.

Thanks for this, just on the off-chance, have you ever encountered an ABS Wheel Sensor issue? I have had a problem illustrated in this youtube video. I followed the same course of action as they guy who made the video but so far the problem has not been resolved.

I'm due to take it to a mechanic later on in the week though so perhaps I'll find out that it's a more serious problem than just the sensor.

I changed the other sensor and it's worked. All fine now! No issues. I'd say if anyone encounters the same problem this is definitely worth a try and it only takes about 30 - 40 minutes and costs less then £30
