Since I purchased my 2015 Skoda Octavia 1.4TSI Elegance Combi used in July last year I get this fault code every couple of months or so. I clear it and eventually it comes back.

The engine doesn't go into limp and fuel consumption seems normal. It happens on 95RON, E95 (10% Ethanol) and on 98RON purchased from supermarkets and from "proper" petrol stations so doesn't seem to be fuel related.

Anyone got any ideas as I'm stumped?

 

At first glance it looks like AFR sensor on its way out, that is I think this has the wideband type (6 wire). They're not cheap, so it is worth testing/getting it tested before sticking a new one in.

 

If you have a full copy of VCDS you can run the diagnostics and if you have a meter you can check the basics of the circuit. You would need to get the manual for this model and engine or have someone walk you through it. I don't have the specifics for this engine. FYI, in my case measuring blocks 030 until 046 are for monitoring and testing the lambda control. Some require you to be in basic settings to run tests.

Yes I do have the latest VCDS and a HEX-NET cable.

 

By AFR sensor do you mean the O2 sensor in the exhaust?

Yeah, the first O2 (B1S1, pre-cat).

There will be specific measuring blocks to monitor and some basic setting tests, hopefully someone comes along to advise on that.

In the meantime you can do certain multimeter and monitoring tests to check the basic functionality of the sensor.

Is there any reason a Skoda Dealership is not dealing with the fault, diagnosing and resolving?

Warranty woek.

 

Where do you get E95 with 10% ethanol in the UK.  Are you buying E10 ?

Where do you buy 98 ron?

http://volkswagen.co.uk/need-help/owners/Fuel 

 

Super Unleaded from Sainsbury, Esso, BP, Gulf etc is 97 ron,  not sold as 98,  sold as 97 ron minimum.

& Tesco Momentum 99 , Shell V-power nitro+ & Costco Super unleaded are 99 octane.  99 ron minimum.

 

More than 1/2 the passenger cars in the UK use supermarket fuel, and the supermarket suppliers supply independents as well, 

so unlikely fuel related, unless previous misfuels.

Greenergy and Royal Dutch Shell share importation ports, storage facilities etc.  Co-owners at some.

Differences Between E85 And E95.mhtml

Getting to a dealer is a pain, so while it's not affecting drivability I'm living with it until the next service.

 

I didn't get E10 or 98 in the UK, but on holiday in France. Some petrol stations didn't have "normal" 95 only E10 and my brother had a theory that with his Zafira he got better mileage on 98 so I tried it to (no difference).

My mate put in E10 by error in a 1.4 tsi Twincharger and got 30 miles before he needed recovered, exhaust control light, the EPC light then the Turbo Charger shut down and 2 cylinders.

He got the fault codes cleared, new injectors, ECU back to factory setting with stage 1 removed and put it to WBAC's.

 

The new owner came on the forum asking about the car as every time he used Cruise Control the warning lights came on.

I just ignored those posts and did the VW Trick, selective memory loss and deaf dumb and blind.

 

The E10 will just be a coincidence in your case.

 

I would make the effort and get the Warranty checks done sooner than later and not wait until service time.

 

PS

100 ron on continental Europe is lovely, 

and a 1.4 TSI should benefit Tesco Momentum 99, Shell V-Power Nitro + or Costco 99, 

even if just cold starting in winter and longer Spark Plug life.

 

Best have all 4 spark plugs out, the condition and gap checked, and maybe worth replacing for the £40 the plugs cost.

Had a reply on the Ross-Tech Forum from DrPeter (Ross Tech employee) that I don't have the latest engine ECU firmware - currently have 7861 but the latest is 9170.

 

Any other Octavia III 1.4TSI owners able to share their engine ECU firmware version?

There certainly is a flash file that looks like it would take your ECU to 9170.

 

I'd goto https://erwin.skoda-auto.cz and pay for an hours access, you should be able to type for VIN in and get any TSB/TPI for your car. One of these might tell you more about the 9170 SW for the ECU...

And while you're at it get everything else that is related to your car, an hour is plenty of time to get all the manuals and data.

Were you able to find the cause of the random P2196 code?

 

I have a Golf with the CHPA engine and it appears to be having the same issue.

 

Any info would be greatly appreciated.

After four months of frustration, it looks like I've finally got mine sorted...  by replacing B1S2.

 

I did replace B1S1 AFR sensor quite early on when I believed it was the problem, which it was not. (both, from not enough understanding & using a very basic OBDII scanner).

 

It would only happen every 500-1000km, so I got an ELM327 adapter & used Torque app to log data until it happened again, then graphed it afterwards.

It revealed the downstream oxygen sensor (B1S2) was occasionally drifting quite lean, resulting in pending code: (P2270: B1S2 stuck/biased lean), which would generally clear itself during the next drive cycle, making it quite hard to catch.

 

I assume when the downstream sensor drifted lean, the PCM added more fuel to keep cat converter efficiency correct, which caused the upstream sensor to be rich, and as soon as the downstream sensor had a realistic output again, it would store the code: (P2196: B1S1 stuck/biased rich) and the CEL would light up, making B1S1 look guilty, as the P2270 was gone at next start.

 

I may have got to this conclusion sooner with VCDS, but I won't know for sure as I don't have it.

I did learn a lot from ScannerDanner's videos though.

 

Since replacing B1S2, a give away is how long it takes to start outputting voltage via the scan tool, the old sensor would take 5-8 km, whereas the new one is alive within about 2 km. (I'm in the country).

Readings are now very stable & generally around 0.75-0.8v, the old sensor sat around 0.6-0.7v.

 

I'd owned the car for less than 2 months when the CEL first came on, so it was likely an issue for the previous owner as well. It had always been VW dealer serviced.

 

On a side note, since it had done 95,000km, I was suspicious of carbon build up on valves & ports, so as part of the process of elimination I cleaned it all out.

It was surprisingly filthy, not an easy job with the manifold mounted intercooler & associated plumbing. As a bonus though, idle quality has improved, as well as a small improvement in fuel economy.

Good to know, my car is going in for service and diagnosis in 3 weeks time (the earliest the Skoda dealer in Barnstaple could give me a courtesy car).

Not exact but a similar tale...my MK1 fabia (1.4petrol)  was very lean burn & put out abit more power & always run on shell vpower.....MOT results always so low it only just registered...no fault codes...

 

This engine has two cats, the first is a 200cell metal I think, the second was a 400cell ceramic......I then swapped the second cat for a 200metal race cat......result, faster car but fault codes "to lean" etc....reason, the lambda sensors (first before all cats & second after all cats)...could not detect the minimum % scub (cleaning of the exhaust gases from testing first sensor & last sensor difference)...due to the other 200 race cat...MOT results still way down, & within any spec, but ever so slightly dirty compared to before due to less scrub from the cats. Only way around this was a special stage two remap which would cost, so fitted the old cat back.....

 

Basically those lambda sensors can really sod the engine up even if the car is running 100% & producing no emissions.....

Hello SWBoy !
I have a VW Scirocco 1.4 TSI 160hp version (CAVD Engine code) DSG7 .With the same f#$cking problem -fault code . The 1.4 twincharged version is the same with the 1.4 turbo only version ,so we have the same problem in the same engine...
I have the problem 1 year now , every 100km i must delete the fault.

I have log the car with VCDS and when the car is rolling with low load under 2000rpm, in vaccum condition , with a little of throttle the SPECIFIED value of the lambda goes to 0.73 !!( 10.7:1AFR) while it must be lambda 1( 14.7:1 AFR) . Also with engine at idle the fuel trims go crazy like +18-20% and you can see also at idle 10.7:1 AFR ....
I have log
Exhaust Gas Temperature
Engine Load
Intake Air Temperature
Water Temperature
Throttle position
Timing Angle Retard
nothing from that, all normal...

Also i got from othe 1.4tsi with no problem, the Oxygen sensor, no fix, the manifold map sensor, no fix ....

Is yours stock or tuned?
Please update if you find the problem

 

i just see that you have CHPA engine, not the CAX which is similar to the CAV engine. You have the new gen 1.4 tsi. So your problem is the same as GolfNZ because he has the same engine

Hi - anyone able to help a novice here... looks like I have a similar problem on my 2015 1.4Tsi Octavia. 

 

I get the same error code and noticed it’s telling me the oxygen sensor heater is not passing (see image). 

Does this indicate it’s a different problem?

im pretty broke after purchasing this and am nervous of rocking up to a local garage with all my ignorance and being told I need to spend a lot of money.  

 

I am experiencing pretty much an identical situation OP...

Getting the P2196 code very randomly...Perhaps every 1-2000miles or so...I'm on a mk7 Golf with CPTA engine

OP have you found a fix for the problem yet?

 

Thanks

OP was my partner, we still have the same car and haven't seen the fault for over 2 years - no SW update, no change to the fuel we use but the fault just isn't happening any more?

 

We bought the car one year old and the previous owner was a daily hire company, don't know if that's relevant?
