Hey, are you selling the mib and display?

The mechanic had checked it when the car was with him for the engine mount replacement. He had initially said he'd change the oil but later said that when he inspected it, found that a top up would suffice. 0.5L topped up, iirc.

The average comes out to around 7 Kmpl for like a 10 Km ride. In the city with a lot of traffic lights. I'm concerned because my friends are getting twice that almost in similar conditions. So I try to do a static dpf regen some time and check after that?

Do you know what I should be checking for on the VCDS for this? I do have a lot of short city drives usually. Long drives are a rarity. Always in D, rarely in S. It's the 2015 Mk3 TDI so there's no Eco mode or such.

Oh, I'll do that. Will try an early morning run. I do feel during higher speeds, there's some running noise. Not sure if it's the tyres or bearings. Also, the thing is, the sluggish feeling exists in gears 1-2, maybe 3. Like the instantaneous kmpl shows as low as 2.8-3.1 Kmpl (6.5-7.2 mpg) even when slow accelerating in gear 2. Once it's in 4, it feels super smooth, like the car doesn't engine break if my foot is off the accelerator. I'm wondering if it's a gear thing. The transmission fluid temperature showed 95°C after around half an hour of driving.

Flywheel was making a ticking noise. Engine mount was changed because I could feel the vibrations on the steering. Haha by wheel dents, I meant bent wheel from presumably jumping into potholes. I was feeling vibrations after 100 Kmph. Took it to wheel balancing, they mentioned that the alloy had bents from impact. Got that fixed. You make a good point about the distance/time. Thing is, my first 15 minutes is usually stuck in traffic traveling maybe 3 Km. I'll try an early morning run without traffic and see where I land.

I haven't. But I had the pads changed when I bought it around 5 months back.

Hello, good folks of briskoda. I need some help figuring out why my mk3 2015 Octavia TDI is giving me low fuel efficiency. I'm getting anywhere between 5-9 kmpl (11-21 mpg) in city driving and around 17-19 kmpl (39-45) on highways. The latter seems decent but the city numbers seem way below what my friends with Octavias and Jettas are getting. In the city, I can almost feel a sluggish pull when I'm in lower gears. And when I've taken my foot off the accelerator, the engine braking seems too eager to slow the car down. For background, the car has run 160k km (100k miles). I bought it around 5 months back secondhand. Changed the flywheel, engine mounts, wheel dents were removed, aligned and balanced, full service was done with engine oil,fuel filter, oil filter and air filter changes, gear box oil was inspected and topped up. The previous owner mentioned that he had changed the timing belt and water pump roughly 70k km (50k mile) ago. I met up with a friend last weekend and he ran a bit of vcds diagnostics. Turbo performance seems to be good. One thing that stood out was that the fuel pressure was lagging behind the ECU specified value. PFA graph. When he cleared the short term fuel trims, on my drive back in the city, I was getting 12.5 Kmpl (29mpg). This was much higher than the usual and the car seemed eager to start moving in the lower gears as soon as my foot was off the brake. Not sure if this was just placebo. I didn't get a chance to check again since I was away for work for a week or so. Got back this week, driving around, back to square 1. 5-8 Kmpl in city (albeit start stop traffic) I got 17.5 on late night drive to airport, which compared to other people's cars on long drives, seems lower. Occasionally, while driving, I get the error "only leave vehicle in position P, please visit workshop" but it comes on for a second and goes away. Not sure if this is doing anything. Also, the timing belt stretch was measured at 3.98°. Any ideas on where I should start looking for solves? Considering doing a complete change of DSG oil, fuel pump change, timing belt and water pump but that's a big spend.

Basically what the title says. I have a 2015 Octavia Mk3 TDI. I noticed recently that my side mirrors have stopped dimming. The rearview mirror dims perfectly but the side mirrors don't. All the other functions of the side mirrors seem to be working. I had gotten a full service done at a non-dealer workshop and they reset the service timer. Not sure if that reset some code because I didn't check if this happened since then. Previously, once when I got a car wash done, the mirrors had stopped dimming and then in a few hours, automatically started working again. Doesn't seem to be the fuse because the rearview mirror seems to be dimming. Anybody have any idea where I can start looking? Or know the code to get them dimming again? Thanks in advance.

Hey hey. Got myself a 2015 Octavia Mk3 TDI 2L. Absolutely loving it. Spent around 20% of what I got it for on repairs (Flywheel replacements, engine mount replacements major expenses) but it seems to be finally running great. I've had questions to ask since I got the car, looking forward to interacting with you all 20240602_133310.heic
