Never got to the bottom of this. I needed to chain the timing chain and associated parts plus oil pump sprocket and chain. Do i need to do timing chain adaption or will the ECU relearn with driving? Thanks

Thanks for your help trying to resolve my problem. I'm back home now for 2 weeks. My neighbour has a Skoda Rapid, not sure of the engine but if it's a 1.2TSi CBZB I hope to scan it tomorrow and record what the knock sensor voltages are.

Thanks all for your replies and suggestions, back home for 2 weeks so won't be driving this car but instead I'll be driving my GTI. Thanks

Hi, thanks for your reply. I've used Tesco Momentum E5 99, BP Ultimate 97 E5, BP E10 95 all with the same results. With regard to cylinder 6 I believe I don't have control over that. Do you think I should take it to a Skoda dealer and see if I can get the ECU re programmed. I had it into a...

Uwe, do you know if this measuring point is pre or ECU amplified voltage? Thanks for your replies.

Results below. Is this the voltage expected? Thanks Tuesday,18,July,2023,18:15:30:01151 VCDS -- Windows Based VAG/VAS Emulator Running on Windows 10 x64 VCDS Version: 23.3.1.0 (x64) Data version: 20230421 DS346.2 www.Ross-Tech.com VIN: TMBFN25J6E3132419 License Plate...

Thanks Uwe, will try this.

Hi Uwe, sorry should have indicated this at the start. I used the HEX+CAN I use this car at a holiday location I'm currently at and only have the HEX+CAN. The reason I asked the original question a local specialist changed the knock sensor and said if the fault persists I'll need an engine...

Tried to do a control map, no file was generated. Anyone know why? Steps taken. options controller channel map controller address 01 output pre-label measuring values go How do I insert screen snip? Thanks

Will do that in the morning. Thanks

Tried using VCDS 23.3.1 to measure knock sensor voltage ( amplifier factor included ) group 26 and test knock sensor short trip group 28 but this area is greyed out. Is it possible to view theses values elsewhere? Clear the codes car drives fine for a few hundred miles then low power comes...

Thanks. I'll have a look at the blocks. The sensor was replaced by a VAG specialist, I assume it was correctly torqued.

Thanks for your reply. Are you referring to Measuring block groups 010 to 019 and groups 020 to 029? How doI rest these learning values? Thanks

Thanks for your reply, new knock sensor has been fitted. Below is a scan done this morning with low power still present. But no fault shown in scan. Tuesday,11,July,2023,09:31:03:01151 VCDS -- Windows Based VAG/VAS Emulator Running on Windows 10 x64 VCDS Version: 23.3.1.0 (x64) Data version...

Not that I know off. When it drives normally, drives like a 77Kw car

The car can at times drive fine for 300 or 400 miles then the low power cycle happens.

I use Tesco Momentum 99 E5 and have used BP Ultimate 97 E5

I have a 1.2 TSI CBZB Fabia that will after a random slight hesitation loose power and display no EML. I scanned the car and it has this fault code Tuesday,09,May,2023,17:03:38:01151 VCDS -- Windows Based VAG/VAS Emulator Running on Windows 10 x64 VCDS Version: 23.3.0.0 (x64) Data version...
