 Trustindex verifies that the original source of the review is Google. Thank you guys for your professional, dedicated and honest opinion. You made my day by fixing my son's car so he could use it for DoE at very short notice. Max and Kay were brilliant and I would definitely recommend this garage as a organised and trustworthy business. Keep up the good work.

 Trustindex verifies that the original source of the review is Google. I was recommended Onyx to get my diamond-cut alloys refurbished. I am located an hour away but the recommendation was important so decided to leave my car with these guys. First impressions, the team were very polite, friendly (Essan, Ben and the guys that actually did the refurb in the intense heat) The prices were competitive. And the quality of work was super. There was slight miscommunication post the sale (which happens) but I was pleased they resolved this to my satisfaction. One idea I would suggest is advising the customer 'before' the work starts that the TPF valves may need replacing so we have the option to decide whether to do it whilst the wheels are off anyway rather than post refurb to avoid scratching the newly done alloys. Otherwise happy with my overall experience.

Frequently Asked Questions

What is an AdBlue delete?

An AdBlue delete involves reprogramming your vehicle’s ECU to disable the AdBlue system, preventing related errors and dashboard warnings. This is typically done for off-road, agricultural, or export vehicles where AdBlue is not required by law.

Can you fix NOx sensor faults without replacing the part?

In some cases, yes – depending on the fault, we can reprogram or repair the system to resolve issues. If a replacement is needed, we use high-quality parts for a lasting fix.

Will disabling AdBlue affect my MOT?

If your vehicle is used on UK roads, removing or disabling the AdBlue system could affect emissions compliance and MOT results. We can advise on legal implications before carrying out any work.

How do I know if my NOx sensor is faulty?

Common signs include dashboard warning lights, reduced engine performance, increased fuel consumption, and the vehicle going into limp mode. Our diagnostics can confirm the issue quickly.

How long does an AdBlue delete or NOx fix take?

Most AdBlue deletes and NOx sensor fixes can be completed within 1–2 hours, though more complex faults may take longer depending on diagnostics.

Do you offer a warranty on this work?

Yes – we provide a warranty on both parts and labour for any NOx sensor replacements and guarantee our ECU programming work for your peace of mind.
