Yeah, you do that. It has been 4 days since my 2nd liter and the engine is as new.

Could be fuel pressure sensor? I'm always thinking about that. It's on common rail line I think.
I asked friend from SLO about that what you are using. He said on BMW forum SLO they adore adore that product. He will send me 2 bottles soon |

You have two types of the product. One is "original" Antigripante 25 from FCAR (or TECK - this was before 2017). As far as I know they just changed the supplier, so they only changed the packaging. One should also be aware that on the later bottle - FCAR (white sticker), there's a slovenian declaration sticker on the back saying that it's not suitable for Common Rail diesels but there's no warning on the older TECK (blue sticker) bottle. I've also read that there was/is Antigrippante 12, which is suitable for CR and it's the same as 25, but it's diluted.
The second is AntiGrip+ aditive, which is suitable for CR diesels, but that's a different story. I've read a lot of forums and there were no problems with the good ol' Antigrippante 25 on CR whatsoever. Disclaimer: Do your own research and do this on your own risks. |

I guess it could also be a dirty fuel pressure sensor. I think there was something clogging up the system... Maybe also a return line from injectors. Last time I checked the injectors, there was a lot of rust particles in the return line (because in SLO we have the best diesel in the europe). |

So I want to get back to this as I resolved some things.
The "slow start" problem was due to an old/lazy starter motor. I've changed the unit with aftermarket Bosch and also replaced the battery and now car starts like a champ. Rough idle problem went away after I added that additive and for now it's still OK. |

Thanks for the feedback. My friend from Slovenia bought additive for me, but other friend who should pay me a visit didn't manage to come now, but in 3 weeks. I want to try it

But keep in mind that you're doing that on your own. I mean, I don't want to fool you, but it really did wonders for me and few people I know, but there still can be some drawbacks (depends on your system's/engine's condition). Maybe you start with smaller amounts? My colleague has 2002 s60 D5 with 500k km and when he put 1 liter of the same additive in the tank reserve, his engine started running rough and it also shut down itself. It started working OK again after he drained the tank and put just diesel in it. But it surely was scary. For me... I'll definitely pour this in at least once a year if not twice (it's kind of expensive). |

I was about to make termin in Maribor for changing rocker arms and lifters, but on the end I found guy near home who is doing only Volvo. Hope.l so he will not mess up |

Do you have a price quote for the lifters and rocker arm? I'm assuming it's somewhere near 1000 €? |

No, by him not. This guy in Belgrade 250€ work. Parts are: 20 rocker arms and 20 lifters from INA 260€ and 40-50€ seals (intake seal, injectors etc). I will do also (probably 20-30€ work) aux belt from INA 60€
And remove AC compressor and change bearing (probably also clutch once when AC is removed. Clutch is ca 60€ I think). Also check the car. Maybe some rear bushes, we will see |
