I tried swapping Injector 5 with 4 and this time its cylinder 4 misfiring. So its the injector. Could I DYI fix it or it has to be a replacement one?

SOLVED

I replaced the injector with a used eBay one and it sorted the issue out, no more misfiring.

I wanted to re-calibrate my one, so I rang up a local injector specialist. They advised me to buy a refurbished one as it cost the same to re calibrate as it involves replacing internal parts and quoted £150 + VAT. The technician also said that my XC90 does not require coding/programming BUT Bosch's part number 0445110251 should match number to number. So it's like just replace and drive. Volvo's part number (30750283) irrelevant.

Taking his 'Bosch part number' advice, I searched on eBay and luckily a local breaker had the same one. I cleared the code and it's running as before now. I thought I'd update you as this might help someone in the future

Cheers
