Yep will give her a good charging one of the days. The average of 12.6v resting is quite accurate. The battery monitor is directly on the battery via Bluetooth on my phone, all locked up overnight so everything shutdown. It matches my multimeter reading and the reading on the obd11. It gets it’s reading from the battery sensor. I do feel the battery is charged to it’s optimal that the car will allow as I don’t do many short trips while doing 1k a week. I never use the heated seats etc One thing i have noticed with obd11 is the brake regeneration mode doesn’t kick in unless the state of charge is 70% plus. I also noticed brake regeneration is turned off when outside temps drop below 6-7 degrees C. Yes it’s a diesel DSG. interestingly the consensus on the net is that EFB batteries aren’t recommended for brake regeneration. They sre supposedly designed for start stop only.

Some more observations in my case. According to obd11 ( if accurate) my battery state of charge hovers on average 70%-73% . I rarely ever see it at 80%. Yesterday i was hoovering out the car so the doors would have been open for 15-20 ish minutes. The interior led lights were on i’m sure. State of charge dropped to 59% which i thought was a big drop. I turned the Ignition on and voltage was about 11.8v. The car started ok. The OBD 11 minimum start voltage after i hoovered the car was 7.35v but the engine was cold so i’m sure the heater plugs were on also so I’d expect that voltage however it generated a fault code in the brake booster system low voltage. I did a cranking test with my battery tester a few weeks ago and the lowest i got was 7.95v For comparison i tested the battery when the car was new. It read 800 amps. The battery is 700 amps. Today it reads between 480-540 amps depending on it’s mood. It reports “ replace” I put a battery monitor on the battery and in the morning it reads an average of 12.6v ( sometimes 12.55-12.63v)

My 2 year old Octavia vRS came with a Varta EFB. It’s not very fresh after only 2 years. My battery tester fails it and i often get low voltage codes on the OBD 11. The car starts fine though and the start stop works ok. The car does 1000km a week and rarely has short trips. They should be fitted with AGM batteries. The AGM in my last car, a Passat lasted 7 years.

Unfortunately my gps lost lock again today. It was strange that it worked so long after that update. Looks like i’ll have to live with it.

I suppose it’s possible that they hadn’t figured it out how to fix it with software until now. It must be over a week now since i updated. It hasn’t faltered once. It used to lose lock every second day. I also noticed on the Skoda app that the car’s location is exact and not moving around. Fingers crossed it stays that way!

I had the same issue. The latest software update 03A8 for the OCU seems to have fixed mine.

I’m not sure if it’s just a coincidence or early days yet but since i updated this software update my GPS has been working perfectly. I had issues where it lost GPS and i was driving across fields, lakes and different towns lol

Interestingly these two new codes appeared today never had them before. However there were no malfunctions. Everything working fine.

Since i bought the car new i have had that code come up every so often. I haven’t had it for a while until this week. It’s the first time it’s come up twice in the one week. Maybe it’s part of our typical octavia glitches.

Yep. It came up Tuesday. I cleared it. All ok yesterday and came back today. Cleared it again and so far hasn’t returned .

The car had a lot of driving this week including a round trip to the UK from Ireland. Voltage reads good anything between 12.6-7v.

Anyone come across that error code? It has happened to my car twice this week. When the fault occurs it annoyingly affects the infotainment system. It takes ages to boot up “ loading settings “ when you get into the car. Also you can’t access the car via the Sloda app when the code is active. I read somewhere it might be the SOS back up battery going faulty ? Anyone else have this problem?

Mine have stopped also.

A couple of low ones via the BM2 over the last couple of months. I constantly get ‘U’ data bus codes etc

A test i did today. “ replace”. The strange thing is if i didn’t do any tests or diagnostics i would never suspect a failing battery. Cranks fast and starts quickly and the start stop works perfectly. I suspect it won’t be easy to get replaced under warranty if the car starts ok etc.

The alternator is charging fine. The brake regeneration works now and again but it seems to constantly charge the battery mostly 14.5-14.9v. The cranking voltage readings i get are from a bm2 battery monitor and a Topdon battery tester.

The lowest i have seen is 7.96v.

The brakes seem to work fine regardless of the code. I’d say my battery just isn’t as good as it should be despite it being only 19 months old. Performs ok ( cranks fast and start stop works ok) but cranking voltage can drop below 9.6v at times.

No. I think the reason i get the fault code is that my battery isn’t the freshest.

I intermittently get the fault code P056200 low voltage on the brake booster module according to my OBDeleven. According to the OBDeleven website it says “This code is a big red flag - you shouldn't drive your car when this appears.” Is that statement an over exaggeration or is this something that needs immediate attention?

Battery reading after a test. Funny thing is it cranks good and the stop start works flawlessly.

Batteries can fail two different ways. Either by low cranking ability( the battery will have loads of reserve capacity) or low reserve capacity( the battery will have loads of cranking ability) If it’s the latter testers might give the battery a clean bill of health. The problem arises when you sit in the car listening to the radio for 15 mins and it won’t start.

The problem I’m worried about is what the longterm effect will be on the DPF. I used the 0w30w on my last car and it didn’t burn a drop of oil in 10,000 miles.

I have the same engine in my Octavia vRS. It seems they do use oil. Mine goes down to halfway on the dipstick after 3.5k.

Yeah i definitely get the U112200 and U112300. A new one i get sometimes is “ low voltage” error code in the brake booster module.
