Octavia VRS 245 GPF/OPF?

[gtmuk]

I've got a 2018 / 68 plate Octavia Estate VRS245. How can I find out whether it as a GPF/OPF? If it has where is that fitted along the exhaust system? Car was supplied in Nov 2018 if it helps.

Has there been any trouble with the GPF on cars where it is fitted?

[SashaGrace]

Put simply if you have a Challenge model it will have a GPF, if you have the 19’s half leather elec heated seats, glossy grill etc as standard than you don’t have it. If you have a 245 and it has none of what I have just listed as standard then it does have it. The build date will confirm definitively. As with everything there will be some people who have been unfortunate enough to buy bad cars but on the whole the technology is a bit new to make solid predictions about. I have a diesel with a dpf with 122k miles on it and never seen hide nor hare of the dpf light or any indication it has one other than normal regenerations at expected times in my 2 years and 57k miles of ownership. Eventually it’ll get full of ash and I’ll decide then what to do about it.

[gtmuk]

It is not a Challenge model, and it hasn't got any extras / options except tinted rear windows. 18" wheels, no leather etc. The car was registered 15-11-18, I don't have a build date but I would expect around Sept 2018. Is the GPF something I can identify by physically looking at the exhaust system?

Interestingly on one of the Facebook groups I noticed someone with a Nov 17 'original' 245 and he had been told by numerous specialists and tuners that ALL 245 engines are fitted with GPF, no exceptions. Including his Nov 17 car that they'd worked on the exhaust of...

 

I'd be interested to know where in the exhaust they sit and see if my 2017 car actually has one after all. 

[SashaGrace]

First I’ve heard of this, every publication I have read states that this an MY19 only change and no pre MY19 owners have ever reported noticing a regeneration and they are just like DPF regeneration so you would notice.

[Kenai]

Was the first I had heard of it too. Came up about a week ago in the Mk3 OC Group on a post about an exhaust, you'll find it if you search for GPF in the group.

 

Like you say, I've never noticed any kind of regen behaviour in mine. I wonder if there is anything that would show up on OBDELEVEN like a 'last regen' counter? 

[silver1011]

The GPF is far less intrusive than a DPF, it is unlikely you'll be able to tell from the drivers seat if it is regenerating.

 

It's location is the same as the DPF, post combustion, pre-catalytic converter so expect to find it right at the back of the engine, low down close to the bulk head on the early part of the exhaust...

 

 

[bigjohn]

I think OPF regens are always passive as the combustion temperatures are higher.

 

I always thought the OPF came in with MY 19 changes to all direct injection petrol cars to be able to achieve Euro 6d temp - and a new November 2018 VRS probably would be MY 2019.

Was me.....VRS, AMD and VRT who have all worked on my car have confirmed that it has it. AMD struggled with the stage 2 map to get the numbers it should be compared to a 245. After some investigation, car on ramp they confirmed it had. VRT also confirmed as the injectors are different from the previous model and these are inline with the new engine for the emissions.

What year is yours again Chris ?

 

Mine's a launch edition MY18 & I'd be surprised if i had one but, it may explain some of the whooshing sounds rear passengers hear when I'm on it.

 

BTW what did your rollers say it came out as ? Anyways I'm sure we'll get more chance to discuss it at the JKM day 22/02/20

Mine is a 245 special, registered Oct 17.

 

Mapped stage 1 was 302bhp, down pipe fitted went down to 288 but should have  been around 310, once mapped it was back to 305. Fitted IC and went back on rollers at The Tuning Society and got 317, should have around 330 and then back to AMD and got 317 and they mapped again, and and got just under 330, but really pushed things.

 

spoke AMD at the time and VRT and VRS when I was there they other week and they All confirmed had the egr or whatever and that the new engines also have different injectors and fuel management that is restricting the power by a good 10-15bhp. They all commented that they see similar restrictions on the Golf’s and Cupra’s and are all 10-20bhp below where the previous engines were.

 

AMD and VRS both expected mine with my mods at stage 2 to be around the 340 mark fairly easily but they had to work hard to get 330.

 

Can only go by what I am told but this is from 3 different places.....
 

Hoping to still make the 22nd Feb but the Mrs is now off to the US for a week and flying out that day. So for me, I’m hoping to still get there but could be a turn up, get on next and then depart....no fun with a 2.5yr and 6yr old!!

Thinking about it many moons ago when they first started implementing DPF's on diesel Octavias the VRS diesel model was an early adopter!

I believe the gpf regenerates without the need for active regen due to the higher exhaust temperatures, so you might not notice like you would with a dpd.

Choked exhaust 😭😭😭😭

 

So it another grand for a new exhaust system to go FULL stage 2  Hmmmm kinda explains why I was down on power compared to a Mk3 vRS 220 with roughly the same DTUK setup, not a lot but, enough to hurt😤😤😤

Quite possibly. Seems the new engines, once mods etc done, are around 10-15bhp lower than the previous engines. Basically the 230 engine is more tune-able than the 245 due to fuel management, injectors and gpf differences.

As said, I am only going by what 3 different places have told me and its all to do with the emissions regulations that came in. Also told its why the new Cupra's are 290 and the old are 300.

[Ecomatt]

There may be slight power differences on paper but I bet negligible difference in on the road performance. 

Not petrol related but it would be interesting to find out about these filters fitted to reduce emissions. I was reading an article that stated after testing the dpf fitted to diesels do keep the emissions down, however when going through a regeneration process they are way above the emissions limit. Seems pointless if all that good work of keeping emissions down is undone when the dpf cleans itself. I wonder if the petrol filter is the same?

[gtmuk]

I've now looked at and under the car and taken pics. The first one is the turbo and the top of what could be a combined gpf+cat. The second is that same thing from underneath, it basically sits above the RHS drive shaft. Next comes a flexible coupling/bellows. Then a pot that could be another cat (or something else), it is roughly in the middle of the car. Then a "triangular" silencer. After that the pipe splits in two, and then there are the end pots just before the tailpipes - didn't bother taking pics of that.

 

This whole saga is triggered by the engine warning light having come on a few weeks back, and the Skoda garage saying it was the DPF. When I pointed out it is no diesel they stuttered something about a temperature sensor. At that time I hadn't even heard about a GPF. All I want to be able to understand is there a GPF on my car and could this "clog" and then trigger a code which lights up the engine management warning.

Did you have it rolling roaded before any mods were done by any chance?

Technically no, but prior to strange 1 map, I only and CIA and turbo elbow and got 265.

Thanks Chris.

What's a CIA?

Does the sports cat include a GPF? 

And how does the Scorpion exhaust sound?

CAI is Cold Air Intake. No idea on the sports car, I would assume not and yeah it’s good. Nice rumble and. It too loud, I have the resinated system.

265 from just a Cold Air Intake and turbo elbow, that's impressive.

Does the exhaust drone at all? 

If you don't mind me asking. How much did the mechanical mods and remap cost? 

And what engine oil are you using?

Sorry about all the questions. I've recently bought a 245 and I'm interested in what can be done and what sort of gains I can expect to see.

Apparently so and there is many a YouTube video showing the elbow can be 5-10 on its own.

 

Ramair intake and elbow kit was about £250

Stage 1 map around £500

Scorpion cat back, £650

Scorpion down pipe £700 fitted

Wagner intercooler £750 fitted

Stage 2 map update £125

 

Exhaust cat back no droning at all, you get a little with the downpipe but nothing some sound deadening won’t sort.

 

Running around 330-335bhp and 380-390 lb/ft.

 

Engine oil is a 0-w20 as per Skoda recommendation.

 

Depends on budget, but intake, elbow and map will see you around 300-310, cat back just sounds nice and adds nothing power wise, but you could do downpipe and std cat back and that will see some gains and will make the std exhaust sound nicer as well.

Good work Chris, money well spent.

My local Skoda dealer use 0-w30 Shell Helix, but I've seen other people talking about 0-w20

Does the exhaust pop & bang by the way?

Thanks mate.

Skoda will tell you 5-w30 for pre 245 but the 245 should be 0-w20 (did my oil change the other week).

 

Nope, no pops and bangs.
