Why is my car beeping for no reason?Dear Alex,While reversing my 2016 Volkswagen Polo from a parking space, I heard three loud beeps. These repeated every 10 to 20 seconds on my way home. There were no warning lights on the dashboard, and the car wasn't overheating even though it was a hot day. As I neared home, the beeps stopped. A local mechanic went through the diagnostics; nothing was amiss. Yesterday I did about 190 miles, watching the dashboard all the time, but the beeps didn't return. What could have caused this?– PHDear PH,The three loud beeps you sometimes get in modern VWs are usually an urgent warning of a serious issue, such as low oil level or pressure, worn brake pads, an engine-management fault or an overdue service.AdvertisementAdvertisementAll of these faults, however, would remain present and wouldn't just vanish. In addition, they would be accompanied by a warning light or dashboard message or would leave a fault code in the car's memory that would have been picked up during the diagnostic check.These beeps can also warn you that the handbrake is still on while the car is moving. In this instance, I'm going to guess that it was not – because if it were, the handbrake warning light would have been displayed on the dashboard.The sensor for the handbrake may be faulty, however, or the wiring may have a loose connection. These could generate an erroneous warning for a fraction of a second – long enough to trigger the three loud beeps but short enough that by the time that you've looked down at the dashboard the handbrake light has gone out.If this is the problem, it might be tricky to diagnose properly, because it's obviously an intermittent fault, present for only short amounts of time.AdvertisementAdvertisementMy suggestion is therefore to monitor the situation and, if it recurs, to ask your garage to check the handbrake sensor and its associated wiring. If there's no fault detected, ask them to clean the connector to the sensor; the problem could be solved as easily as that.Otherwise, you may wish to replace the sensor speculatively. It's a cheap and relatively easy part to replace. If it cures the fault, you're in clover. If not, at least you've ruled it out and can investigate other possibilities.Our expert recommends the Toyota Yaris Cross as an affordable, economical vehicleDear Alex,I am thinking of selling my 2006 BMW Z4 with 103,000 miles and my 2015 Mini Countryman with 73,000 miles, replacing them with one low-mileage used car. I do about 2,500 miles a year in the BMW and 8,000 in the Mini, with few long journeys. The Mini meets all my requirements, but I would like something newer and more economical. My budget is fairly flexible. What would you recommend – and should I consider leasing?– AGDear AG,Leasing works for many people, particularly when you consider the lack of hassle involved with a brand-new car. But if you have the capital, it usually makes more sense to purchase outright because for private buyers the car's depreciation will almost always cost less than undertaking any sort of finance.AdvertisementAdvertisementSo the question depends on two factors: your budget and whether you can charge a car at home.Your two cars combined are probably worth £6,000 to £12,000 in terms of their part-exchange value. You mention some budget flexibility, but I'm not sure how far this extends, so let's assume you have £15,000 to £20,000.If you can charge at home and you're willing to switch to an EV-friendly electricity tariff, an EV is worth considering. Shorter journeys are where EVs shine, so one would work well for you.I would recommend a Hyundai Kona, which is a comfortable, user-friendly compact electric SUV, slightly larger than your Mini but not by too much, with a decent chunk of the original five-year warranty remaining. You'll have to spend closer to the top of your budget for the latest-generation model (which is worth doing).AdvertisementAdvertisementFor example, I found a 2024 Kona 65kWh Advance with 11,000 miles for £19,750, which will have about three years of its original warranty left.But if you don't fancy going electric, a hybrid is a perfectly sensible alternative. The Toyota Yaris Cross would probably be the best option. It's about the same size as your Mini, which means it's smaller – albeit slightly less roomy – than the Kona.Toyota's latest hybrid powertrain sips fuel, reliability should be exemplary and, if you use a main dealer for servicing, you can keep it in warranty for up to 10 years from its date of first registration. I found a 2022 Design with 27,000 miles and a full history for £18,000.Try full access to The Telegraph free today.
