Our Services

Technology and innovation play a pivotal role in the work that we do at Harrow-on-the-Hill Motors. Most of today’s mass-produced vehicles are fitted with an engine control unit (ECU) that controls engine actuators to improve performance and efficiency. The ECU interprets data sent from sensors and adjusts the actuators to maintain performance.

When performance is compromised, a code is stored within the ECU and specialist reading equipment is needed to identify the problem.

We refer to code reading as vehicle diagnostics. Our garage in Harrow specialises in all aspects of modern engine management. We have trained technicians who use manufacturer-approved equipment to locate all faults in your vehicle’s on-board computer.

Harrow-on-the-Hill Motors have always been leaders in trade and industry innovation. By playing close attention to changes in the automotive sector, we are always prepared when new equipment becomes available. Our company invests heavily into engine management tooling so that our technicians can perform vehicle diagnostics on any vehicle.

Most faults are indicated through warning lights on the dashboard and we strongly recommend that vehicle owners in Harrow should have their cars inspected as soon as possible so that the cause of the fault code can be identified. We also provide vehicle diagnostics for airbags and ABS braking systems.

Reading the code is relatively simple. We plug a diagnostic tool directly into the ECU port and a sequence of fault codes is referenced. This gives our technicians a clear indication of where the problems lie. Once the repairs have been completed, we reset the ECU so that it is ready to control the actuators again for optimum performance.

Sometimes, your vehicle may run poorly even if the dashboard isn’t displaying a warning light. We can use our engine management equipment to measure performance and locate potential problems at the earliest stage. Having vehicle diagnostics undertaken as soon as a car starts to run poorly can identify issues sooner and save on long-term repair costs.

If you live in Harrow and have concerns over your vehicle, call in to see us today and a technician will perform a full and affordable diagnostic check. This will give us the opportunity to recommend essential repair work that could preserve vital engine parts for many years into the future.

If your vehicle has failed the MOT test because emission levels are too high or if you can’t hear yourself think when driving because of loud rattling noises, a full or partial exhaust replacement could cure the problem. We operate from a fully equipped exhaust centre based in Harrow. Our technicians can provide a free inspection of your system, quote a competitive price and book your vehicle in for the required work.

All fitters at our exhaust centre are trained and qualified to perform replacements on any vehicle make or model. Because the exhaust system is constantly in use while the engine is running, it is one of the hardest-working components on any car. Wear is inevitable and replacement is the best way to eliminate ongoing issues.

Our exhaust centre in Harrow will only supply and fit high quality replacement parts on your vehicle. While there are many low-price patterned parts on the market, many of them are poorly manufactured so it’s almost impossible to achieve a perfect fit. The exhausts that we use are made to manufacturer specifications and covered by a full one-year warranty.

Most garages charge fixed prices for exhaust replacements. If it only takes five minutes to replace the defective part, you’ll still be charged for the entire time allocated to your vehicle. Our exhaust centre treats all jobs individually and we will only quote a price once we’ve seen how much work is required.

A new exhaust system allows noxious gases to flow through the entire system before it is dispersed through the tailpipe. This helps your engine to breathe and, ultimately, perform better. If your vehicle has failed a test on emissions, a new exhaust should help to lower previous levels and increase your chances of an MOT pass. This is a sound environmental benefit that makes the world a better place for everybody.
