Rough Idle, not HPFP related

Hello,

I had faulty HPFP on my MINI Cooper S 2008 (R56, N14 engine). It's solved for few months, but now having another issue. At cold starts my car is having very rough idle. It's getting a bit better when warmed, but still not perfect. Timing is jumping from negative 5 up to 12 degrees. Coils, sparks, head cover replaced, intake valves cleaned. No effect at all.

This is the video with EXACTLY same behavior: https://www.youtube.com/watch?v=VaLdB_9avRk

I can capture my video if needed.

PS. Chain and tensioner are NOT yet replaced (I got the kit but need to narrow the issue down first).
No error codes apart from random misfires across all cylinders, which makes sense on those negative to positive angles. Compression is above 160 all around.

Also, post catalytic CO2 is showing constant 0.0000134 volts, which doesn't make sense, but couldn't fix it so far. Perhaps wiring issue, but want first to know if it's related or not (not sure co2 sensor can affect the mixture from cold starts).

No adaptation done before/after valves cleaning.

Thanks in advance, any help is highly appreciated.

Likewise, post synergist CO2 is indicating consistent 0.0000134 volts, which doesn't bode well, however couldn't settle it up until now. Maybe wiring issue, yet need initially to know whether it's connected or (not certain co2 sensor can influence the blend from Essay Help frosty begins).

It truly sounds like the HPFP. Had nearly the identical signs. Here is a guide I made when doing it HPFP . Some humans have said they had them replace at 50k miles perhaps 10k much less. Essay Writers UK

it's supposedly a small percentage of CR TDI's that suffer the HPFP failure. I recognise i'm keeping data of all of the gas I placed into my TDI, just in case.

Lots and lots of engine replacements, many for 2 items that do not even exist in other engines plastic timing chain guides and a cam pushed vacuum pump that may seize. Notice all of the one superstar critiques inside the listing, with an average rating of much less than out of five stars.

Well, if you put coolant into the tranny, that's not cool. That would need to be flushed out. If you meant coolant to the radiator, okay, but it is overheating anyway. Maybe even needs a radiator.
