I sent three injectors to this company…
I sent three injectors to this company in Peterborough for refurbishment, and the total cost was over £450. After reinstalling them in my car, fuel consumption increased dramatically, causing the DPF to regenerate far more frequently than normal. I contacted the company and made a complaint, but I was told that the injectors had been refurbished correctly and are not leaking.
To rule out any other causes, I purchased and installed brand-new injectors. As soon as the new injectors were fitted, the excessive fuel consumption and frequent DPF regenerations disappeared completely.
Based on my experience, the refurbishment was clearly not successful, despite the company's claims. I cannot recommend this company. It appears that worn components may have been reused rather than properly replaced during the refurbishment process.
