An engine management light (EML, also called the check-engine light) means the ECU has logged a fault. It rarely means stop — but it always means find out. Drova brings manufacturer-level diagnostic kit to your driveway and turns the cryptic light into a plain-English answer.
The EML can be triggered by hundreds of different sensors and components — from a £15 lambda sensor to a £900 catalytic converter. Guessing is expensive, which is why mainstream chains often quote big numbers without confirmation. Drova pulls live ECU data, stored codes and freeze-frame data, then tells you the cheapest fix that actually solves it.
We cover Lincoln, Horncastle, Louth, Boston, Sleaford, Woodhall Spa, Coningsby and Skegness for warning-light diagnostics — usually same-day or next-day inside the LN postcodes.
Mobile diagnostic — from £69. £69 diagnostic fee comes off the repair if you go ahead the same day. Most sensor jobs are completed on the same visit.
If it's steady (not flashing) and the car drives normally, you can usually drive it short distances to get it diagnosed. A flashing EML means stop and call us — it usually indicates a misfire that can damage the cat.
Yes — since the 2018 MOT changes, an illuminated EML is a major fail. Worth getting it diagnosed before the MOT, not after.
Drova charges £69 for the mobile diagnostic call-out and the fee comes off the repair if you go ahead. Compare to a main dealer who'll often charge £120+ just to plug in.
It'll give you a code, but the code is the symptom, not the cause. P0420 isn't 'replace cat' — it's 'cat efficiency is low' which could be a £45 sensor or a £900 cat. Live data is what tells you which.
Because the underlying fault wasn't actually fixed — just cleared. The ECU re-runs its self-tests and logs the fault again. Proper diagnosis fixes the cause, not the warning.
