The fault code 002A99 typically relates to the camshaft position sensor or the Vanos system. Since you've already changed the camshaft sensors and cleaned the Vanos solenoids, the next step would be to check the oil level and quality, as low or dirty oil can affect the Vanos operation. Make sure the oil is at the correct level and consider an oil change if it's due. Let me know how it goes or if you have any further questions!
It had an oil change back in December 24 with a full service. The problem was intermittent and I was able to clear the code fully using Carly for BMW. As soon as I cleaned the Vanos solenoids, which were relatively clean (Used brake cleaning spray) and also cleaned the sensors, which were really clogged up, the code, ½ engine light, which only shows up in the middle dash, not top of dash, as soon as I start and will not clear with Carly or a foxwell code reader. I have ordered new Vanos solenoids to see if this works. The new sensors looked slightly different than the ones I took out (There was only one hole in the new ones not two as the original ones and the hole was at a different angle, does this matter ?)

It's possible that the difference in the sensors could affect their performance, as they might not be fully compatible with your engine. Ensure that the replacement sensors are the correct part numbers for your specific model. Once you receive the new Vanos solenoids, install them and see if the issue resolves. If the problem persists, it might be worth checking the timing chain and tensioner for wear, as these can also impact the Vanos system. Keep me updated on your progress or if you have further questions!

Apparently they were the correct updated sensors, according to Eurocarparts, they checked against my vin. I’ll let you know if the new Vanos solenoids sort the problem

I have fitted new camshaft sensors, exhaust and inlet also two new Vanos solenoids. The car starts and runs fine, but under heavy acceleration the ½ engine light cones on with a code of 002A98 or 003070 . Any ideas
