Car diagnostics in Livry Gargan: breakdowns, engine, electronics
A structured diagnosis, from symptom to targeted repair
A complete support package to resolve the problem
At Proxi Pneus in Livry-Gargan, we perform electronic diagnostics and mechanical repairs for everyday breakdowns. We handle engine repairs, timing belt replacements, EGR valve replacements, injector repairs, as well as transmission and gearbox repairs, not to mention routine maintenance to prevent further problems. The diagnostic process always begins by noting your symptoms (noise, jerking, loss of power). Next, we read the fault codes, followed by targeted checks: sensors, leaks, fuel supply, tire pressure, wiring harnesses, and road tests if necessary. This method allows us to confirm the cause, not just the warning light, and to offer you a suitable solution.


Fewer random trials, more results on the first visit
Save time and avoid unnecessary part replacements
A good car diagnostic is first and foremost about saving money. By quickly identifying the source of the problem, we avoid "gut feeling" replacements and unnecessary expenses. In Livry Gargan, we often see the same issues: the engine warning light illuminated, loss of power on the highway, exhaust smoke, excessive fuel consumption, or difficulty starting in the morning. Once the cause is confirmed, we reliably restore the vehicle to working order, using appropriate parts and a repair that will last. The result is tangible: a smoother engine, fuel consumption returning to normal when possible, and a more relaxed driving experience. You leave with a clear explanation of what happened and what was done.
Clear explanations and solutions that respect your budget
A reliable method, for all brands, with transparency
Our approach is simple: method, inspection, then decision. We explain our findings, what's urgent, and what can wait, so you can make an informed choice. Depending on the situation, we offer a repair or a standard exchange when it's more suitable for reliability and overall cost. We service all makes and models and can also prepare your vehicle for its MOT (French roadworthiness test), with safety-focused checks and emissions tests available depending on your engine. The goal is not only to pass the test, but more importantly, to ensure it runs smoothly afterward. At Proxi Pneus, you receive a clear quote before any work begins, and we always adhere to the agreed-upon deadlines.
