Hi, I have an Octavia vRS 2.0 TDI -2015 with Webasto. My heater has locked itself and I have a fault code for recirculation pump V55 - short to plus. Does anyone know where this pump is located, and what’s necessary to disassemble to gain access to it?

It’s been barely at the minimum level since I bought the car 5 months ago. Now it’s a bit below even that, and this morning I had a red low coolant symbol show up when I cold started the car at -3 Celsius. I’ve been running the Webasto diesel heater many times a day all winter long, I don’t know if that could affect the coolant level somehow. It’s going in to the dealer in a couple days to change oil in the DSG, I’ll ask them what it’ll cost me for a coolant flush, and might as well ask them to remove the silica bag.

It looks gold-ish in color, and when I dip my finger in the reservoir it’s transparent on my finger. If we assume it’s yellow G13 coolant, is it safe to fill up with red G13? Coolant was most likely replaced 50k km ago when previous owner had the timing belt and water pump replaced, so I don’t really feel like flushing the coolant system to change it, since it seems it’s rather complicated and needs to be vacuum filled if I recall correctly.

Hi, I need to top up coolant, and from what I understand i will need G13 coolant. However, the color of the existing coolant is bright-yellow, and I can only find red G13 locally. Is it ok to mix these colors? car is a Octavia vRS 2.0 TDI MY2015

Mine has two bulbs en either side, the inner ones are used as fog lights and the outer bulbs are used as cornering lights in conjunction with the fog light. Both bulbs are the same type, a H11/16.

Do you have a link to the reverse camera?

How do i know if mine has the fix?

Ah forgot about that. Isn’t it even more frequent if you have the emissions fix as well? Or so I’ve heard

Hm, weird. Today i saw idle at 1000 rpm yet again and the cooling fan running after shutting the car off. Checked with VCDS and it’s showing 15g of calculated soot and 6g measured. Yet VCDS is also saying that last regen was many thousand seconds ago, which should be correct as it shouldn’t even trigger an active regen until it reaches 22.5g of calculated soot. Think i might also replace the pressure sensor just to be safe. FYI, I did reset oil ash mass after the DPF was cleaned, which also resets soot values.

Yes it did. DPF values before cleaning: Weight: 10105 g Back pressure: 79 mbar Flow: 108 m³/h DPF values after cleaning: Weight: 9870 g Back pressure: 27 mbar Flow: 511 m³/h

Hi, im looking to replace the bulb for the cornering light. Is it the same bulb used for the fog light, or is there a separate bulb for the cornering light? And what lamp type is it? it’s a Octavia VRS -2015

Is this rubber diaphragm a part of the valve cover, or is that purchased seperately? If i go the aftermarket route, a complete valve cover with gasket can be had for around 130 euro, so its not all that bad.

Hi I have an oil leak from the valve/rocker cover. I’m going to replace the gasket, but I’m wondering if there are any other gaskets or o-rings that should be replaced at the same time? Only thing that comes to mind is injector seals, but I don’t know if that is necessary. Also, would it be pointless to replace the whole valve cover as well? Since it’s plastic and might be prone to cracking. Car is a Octavia VRS 2.0 TDI CUPA -2015 with 240k km

I’ll try running the engine a bit with filler cap off. I did notice fumes coming out when I removed filler cap though, after shutting off the engine, but it was very mild. Could it be PCV valve?

I did, after getting a check oil level message today, it was halfway between low and full, so I topped it up some. I just recently replaced the filler cap and I never got around to topping up the oil after that. But obviously I will be losing oil, since there is an oil leak from somewhere. I’m just not too confident anymore that it’s from the filler cap, but not sure why there is still oil on the rubber lip around it after replacing the cap. Unless it’s leaking from the filler neck.

Hi, So I noticed there has been oil leaking on top of the valve cover from somewhere, and there are small puddles of oil collected around each injector. I looked at the filler cap as that is the highest point on the valve cover, and I saw oil around the filler cap on the rubber lip surrounding it. I bought a new filler cap and fitted it and wiped off the oil around it, but I can see there is now still oil on that rubber seal around the cap, even with the new one fitted. But I can’t physically see anything that is leaking or bubbling. Will take some pictures tomorrow in daylight and post them here. Any suggestions? it’s an Octavia vRS 2.0 TDI CUPA -2015, with 240k km

I was tempted to try this as well, but it seems more like a band aid solution if anything, if my DPF is really that heavily clogged. I’m looking for a long term solution so I hopefully won’t have this issue again, since I very rarely drive short journeys unlike the previous owner. Hopefully someone knows, otherwise I will update with the process.

I decided to just remove the DPF and send it off to get it professionally cleaned. Will begin with that in the coming days. I haven’t had the car up on a lift yet since I bought it, and seen how things are located underneath. Do you know if it’s enough to lower the subframe to be able to get the DPF out, or do I have to completely drop the subframe altogether?

But this time around, sensor was reading 143 hPa compared to 95 hPa just a minute earlier, both at 2500 rpm idle. Might have to undo the DPF and give it a wash instead, I’m not too keen driving it in constant regens while waiting for the aftermarket DPF to be back in stock. Was hoping that resetting the DPF values would be a temporary fix until then, but not even that seems to be working.

@varooom Don’t know if I’m allowed to post links, but this is literally a minute after the pictures I took before with the different sensor readings. I decided to rev it to 2500 rpm again and this is what it looked like a minute after: https://streamable.com/z84a7r

Not sure what I have, I just took some random pictures. But VCDS does not seem to be displaying two sensor values.

Also, rpm is going up and staying at 1000 5 mins after a cold start, nothing was up to temp yet so it shouldn’t initiate an active regen. Right when starting up it was idling at 600-700 just 5 mins prior.

Here is sensor readings for off, idle, 1500 rpm and 2500 rpm Off: 0 hPa Idle: 34 hPa 1500 rpm: 74 hPa 2500 rpm: 95 hPa

Will do that in a bit and report back. Do you know if the pressure sensor is a 2-port one that reads before and after pressure, or a 1-port that compares to atmospheric pressure?
