🔩 The garage overcharged or did not fix my car — who helps?

Direct answer

A repair is a service with a quote you must be able to rely on: work beyond the quote needs your consent, and a repair that did not solve the problem must be redone at no cost. Complain in writing to the garage first. ULC — Union luxembourgeoise des consommateurs (49 60 22 1) advises and takes complaints about garages; most countries have a motor-trade dispute body — Service national du Médiateur de la consommation (mediateurconsommation.lu) — where an expert looks at the car and decides, cheaper than any lawyer. Commission des loyers de la commune (logement.public.lu) is the small-claims route if the garage is not a member.

🗣️ What to say

"Invoice [number] for [repair] on [date]. [The amount exceeds the quote by [x] without my consent / the fault is not fixed]. I ask you to [correct the invoice / redo the repair] within 14 days. Otherwise I refer the case to Service national du Médiateur de la consommation."

🪜 Step by step

  1. Get the quote in writingBefore any work, next time. This time: what was agreed by phone, message, or the job sheet you signed.
  2. Do not pay the disputed partPay what was quoted; dispute the rest in writing. A garage may hold the car for the undisputed bill only.
  3. Second opinionAnother garage's written finding on the "repair" is the best evidence.
  4. Complain to ULC — Union luxembourgeoise des consommateursGarages are licensed; repeated complaints trigger inspections.
  5. Dispute body: Service national du Médiateur de la consommationAn independent expert inspects and decides; the garage usually accepts.

❓ Frequently asked

The garage keeps my car until I pay

They may hold it for the agreed, undisputed amount. Pay that under written protest and dispute the rest.

They replaced parts I did not ask for

Not payable without consent unless the repair was impossible otherwise and they could not reach you. Ask for the old parts.

A used car broke down a week after purchase

That is the two-year legal guarantee: the dealer must repair. Different page (faulty goods), same bodies.
