Car diagnostics in Tallinn – warning light on? We find the cause

Check Engine, ABS, airbag, DPF, AdBlue – we read the fault codes, explain what they mean, and tell you whether it is safe to drive and what the repair will cost.

Not just fault code reading

A fault code tells you where the problem is, not why. Our diagnostics include reading fault codes from all control units, live data analysis, measuring sensors and wiring with an oscilloscope and multimeter, and a test drive. The result is a specific cause and a quote, not “replace parts until it goes away”.

Common cases

Check Engine and loss of power (lambda sensor, EGR, ignition coils), DPF blockage and regeneration, AdBlue faults, ABS/ESP lights (wheel speed sensors), airbag light (seat mat, connectors), battery draining while parked (parasitic drain), start-stop not working (AGM battery test).

Clearing spurious fault codes

If the fault has been repaired or was a one-off (e.g. running out of fuel), we clear the fault memory and check that the code does not return. Clearing codes before an MOT without finding the cause does not help – we tell you honestly what is actually needed.

Pre-purchase inspection €50

Before you buy a used car we inspect the body and suspension on the lift, read all fault codes and the mileage from the control units, check the paint thickness and give you a written report. It is the cheapest way to avoid a €2,000 mistake. See pre-purchase inspection.
