The shipment i got had a production date of 2019. I also called castrol technical who said to me if its sealed it will have a shelf life of 5 years if opened you have a year to use it. But of course even if you get oil from anywhere it isn't going to be straight out of the refinery.

If they can prove it all with the paperwork and you can call the garage who did the repair and see their reviews online etc. Then it is a serious contender. I would still keep changing gearbox oil every 40k and try to do oil changes at least at 7-10k.

I was told by some engine builders that ideally oil change should be done between 6-7k and disconnect the start stop thing. For those doing oil changes at home it's not problem. Buy a 20litre drum of castrol ll04 off eBay and off you go.

So the doner engine only had 6k on it ? They didn't really say why it was replaced. But if it's a dealer type place I'm sure they will give you some warranty. The price is affordable for the car. I suppose at that mileage it would be best to ask what else has been changed or suspension parts, etc. Gearbox as well. If it hasn't had regular oil changes I guess that would be the next thing to go

You need to use ISTA D and find out what codes you have. Sometimes obd code readers are not as accurate

I was told to stay away from carbon cleaning guys, i hear locally that these guys are really good https://www.terraclean.co.uk/ Find a guy local to you and look at his reviews etc

On Turbo Replacement i have heard of quiet a few people using Universal Turbos on the south coast and having their own re-manufactured. Apparently they were also used by wheeler dealers

Had this for a few days, what do you guys think it could be ? Do I need to connect it to ista to recalibrate it or something. Sensor was replaced not long ago maybe over a year or so

For that price you might as well get a service done at the dealer

quiet a few people just purchased this, I did also. LL04 https://www.ebay.co.uk/itm/Castrol-GTX-Fully-Synthetic-5W30-Engine-Oil-20-Litres/264332398189

There's a guy I'm west London who does it for around 400 genuine parts, fitting/coding etc. My cousin got it done by him and I used him for a few things as well

what was the issue you had ?

i purchased this which is LL04 https://www.ebay.co.uk/itm/Castrol-GTX-Fully-Synthetic-5W30-Engine-Oil-20-Litres/264332398189

I used Bartley BMW a few times, they are all the way in Totton. There is another specialist in Hedge end but they were only like a few pounds difference with regards to servicing compared to the main dealer and they hardly pick up the phone.
