Correct usage of DSG shift stick
PetrolDave replied to Stainesy's topic in Skoda Octavia Mk III (2013 - 2020)
I only use the handbrake when stopped/parked on a steep hill - as backup insurance for the park lock. The only times I use P while on a journey are when a stop is going to be a long one (so I don't have to sit on the brake pedal and annoy the car behind) or when I'm stopped on a steep hill (when I also use the handbrake as mentioned above) - a good example is when sitting on the Leap Gate road at the traffic lights at West Ashton on the A350 for those who know the area. I always move the selector swiftly from D to P, there's no need to move slowly. -
I thought the 1.8 and 2.0 FSI engines in the Octavia have a 5th injection in the inlet manifold to avoid this issue? My previous car was a direct injection 4.2V8 with some owners complaining of power loss due to carbon buildup, but on proper investigation the power loss was due to vacuum leaks in the variable inlet flap system. So my experience is that power loss due to carbon buildup is greatly overstated.

Domestic charging points - A new social dividing line?
PetrolDave replied to EnterName's topic in Electric Vehicles
Sadly that means currently a BEV is not for the many millions of people who live in cities and have to park on the road - often nowhere near their own house, so any charging point they can access will be a public one. -
VCDS 23.11 won't work with generic cables, only VCDS-Lite works with generic cables. To work with VCDS you need a genuine VCDS cable (NOT a clone if you want support).

Price per kWh going down, but standing charge price going up.

Can I update my car software myself?
PetrolDave replied to Dandesc's topic in Skoda Octavia Mk IV (2020 > )
This is something I've pointed out several times on here, many owners seem to think that updating the visible infotainment software updates the whole car - it does not! So quoting the infotainment software version when discussing many other problems e.g engine or ABS is irrelevant. -
1.5 TSI booked in for timing belt replacement
PetrolDave replied to gm73's topic in Skoda Octavia Mk III (2013 - 2020)
Not VAG but... when I had the timing belt replaced on a Vauxhall 1.6 16V engine the dealer didn't replace the tensioner. One week later the tensioner failed causing the timing to massively change and 12 valves hit the pistons requiring a new head, 16 new valves and 4 new pistons - glad I had taken out an extended Vauxhall warranty. -
Tested and working coding Octavia mk4
PetrolDave replied to petopzdiag's topic in Skoda Octavia Mk IV (2020 > )
Ross-Tech currently in negotiations with VW about adding SFD unlocking to VCDS. -
Battery not holding charge. No Parasitic drain.
PetrolDave replied to VAskodas's topic in Skoda Octavia Mk III (2013 - 2020)
That open circuit voltage measurement tells you nothing about the internal resistance of the battery, the only meaningful test is a load test. -
Feb 2023 VRS - Umbrella or not?
PetrolDave replied to thommo41's topic in Skoda Octavia Mk IV (2020 > )
How does the car's WiFi get coverage? - using the terrestrial mobile network (not satellite), so if there's no or poor mobile coverage then that's unlikely to be any better. -
Feb 2023 VRS - Umbrella or not?
PetrolDave replied to thommo41's topic in Skoda Octavia Mk IV (2020 > )
Off Topic warning Wasn't much help to those people in the Peak District who had no power for over 24 hours after a storm, and had to drive several miles to get mobile coverage. With new builds not having any copper feed, only fibre, there are an increasing number of people reliant on often patchy mobile coverage to make emergency calls - be tragic but interesting when the media get hold of a story about someone dying because they couldn't make a 999 call following a power cut... -
Buying used estate - expectation management
PetrolDave replied to MattDB's topic in Skoda Octavia Mk III (2013 - 2020)
Which includes the Mk3 Octavia L&K TSI. -
Octavia VRS recommended oil and change interval
PetrolDave replied to ventmore's topic in General Maintenance
No is the simple answer. Variable servicing interval is reduced from the maximum on driving style, not on oil condition which there is no sensor to measure. -
The Amundsen sat nav on my Mk3 Octavia shows the altitude - all be it incorrectly as Skoda couldn't be bothered to convert metres to feet correctly and simply multiplied by 3!

Massive shortage of Hi-Voltage dealerships.
PetrolDave replied to wantaskoda's topic in Skoda Octavia Mk IV (2020 > )
This highlights the problems of charging infrastructure capacity not keeping up with demand, and high costs per kWh of public rapid (whatever the correct term is) charging points. For most ICE drivers to consider the change to EV the speed and ease of "refilling" needs to be (near) identical. -
In the 25 years I've owned various VAG vehicles (from a 1.4TSI to a 4.2FSI) I've noticed a pattern of zero or low oil usage up to 10,000 miles after a service, and up to 1 litre per 5,000 miles after that. Which is a great argument for servicing intervals no greater than 10,000 miles despite what flexible servicing may say.

Boot Light/Open Issue?
PetrolDave replied to TheJooooosh's topic in Skoda Octavia Mk III (2013 - 2020)
There's a microswitch builtin to the boot lock which tells the boot is open and turns on the lights - sounds like either the wiring to it is faulty, or microswitch is faulty or has gone out of adjustment. -
Satnav refuses to leave home
PetrolDave replied to sarbouy's topic in Audio, Electronics and Security
Sounds like an intermittent connection between the satellite antenna and the head unit. -
One, or more, of the wheel speed sensors has failed. Get a diagnostic scan done which will tell you which one.
-
Sounds like either there is a problem with the connections to the OBDII connector(could be power, ground or Diagnostic CAN), or the CAN Gateway has a problem. I think you need to get a wiring diagram and do some old fashioned wiring testing.
-
A dead short on the CAN bus at the diagnostic connector indicates a short on only the Diagnostic CAN, the CAN Gateway acts like a CAN equivalent of an EWthernet switch so a short on the Diagnostic CAN does not necessarliy mean there is a short on any of the other CAN buses in the vehicle (Powertrain CAN, Comfort CAN, Infotainment CAN, etc.)

DSG changing down too much?
PetrolDave replied to mccririck's topic in Skoda Octavia Mk IV (2020 > )
As previous posts have mentioned, Skoda tune for the lowest emissions rating not for drivability. Drivability has never been the main concern of car manufacturers, 35 years ago when I worked at an automotive consultancy and engine management was relatively new client car manufacturers didn't want drivability just low fuel consumption - the only difference now is they want low emissions. -
Any changes to the vRS spec since 2021?
PetrolDave replied to WaveyDavey's topic in Skoda Octavia Mk IV (2020 > )
MY23 refers to cars made from approximately July 2022 (usually after a summer shutdown but not always) with a VIN year digit that indicates 23 as the model year.
