Expert Diesel Injector Services for Peak Performance

Smooth, reliable diesel performance depends on injectors working correctly. When they become clogged, worn or start leaking, you’ll feel reduced power, poor fuel economy and increased emissions.

At Midland Autocare, we use advanced diagnostic equipment and proven diesel testing methods to identify faults accurately. From initial computerised testing to reconditioning and OEM-standard replacements, we ensure your injectors are restored to proper performance.

What our customers are saying

Yesterday was the first time of taking my car to this garage and I was pleased with how fast they did the mot, within 3 hours it was done regardless of other cars being in on the same day as mine. Excellent service and they even helped me with my problem of putting new batteries in both of my key fobs as i was struggling to do them myself due to it being very tricky to remove the casing, I will definately be using them in the future.

Great service kept me informed all the way through. Took van in with misfire. They told me at each stage what was needed, after testing injectors found they were all not very good. They showed me the reports and explained why they all needed to be replaced. My bill was high but this was down to the parts and not the labour. Would use again. Thank you for getting Van up and running Quickly. Thanks you.
