2013 Mazda Axela air conditioning: why a recharge was not the whole answer

This 2013 Mazda Axela came into the workshop with hot air blowing from the vents. The air conditioning was not cooling, and the compressor was not switching on.Low refrigerant was only part of the problemThe first checks found some pressure remaining in the system. We recovered the refrigerant and found the amount was about half of what should have been there. After recharging the system, the compressor still would not switch on. There was more to investigate than the refrigerant level alone.Fol...

A stone under the seat stopped this MINI passing its WoF

This R56 MINI came in for a WoF and service with a driver’s seat that would not move forwards or backwards. The inspection picked up a few ordinary items, including bulbs, but the stuck seat needed a closer look.Finding what was holding it upThere was no obvious sign of the cause with the seat in place. We removed the seat from its rails so we could inspect the release mechanism properly.Underneath it was a stone covered in hair, wedged under the release mechanism. That small obstruction was s...

When a brake squeak led to more than worn pads

This 2017 Mazda CX-5 came in with an intermittent squeak. We found the rear brake pads were almost down to their metal backing, with the wear indicator rubbing against the disc.We replaced the pads using the electronic parking brake’s service mode. After reinitialising the system, the initial checks and road test seemed fine.Further operation revealed another problem. The parking brake would release initially, but after logging a fault a couple of times, the right-hand rear side stopped actuat...

A split engine mount found during a BMW X1 WoF

A 2018 BMW X1 F48 with the B38 engine came to Speedwell for a WoF inspection. We found that the driver’s-side hydraulic engine mount had split and leaked, and the vehicle failed its inspection.An engine mount supports the engine and helps absorb vibration. A hydraulic mount uses fluid as part of that cushioning. A split mount or fluid leakage is a reason to check its condition and the surrounding components.A worn or damaged mount can contribute to vibration felt inside the cabin. Vibration ca...

Bent pushrods and an engine misfire

The owner had driven about 5 km after buying the vehicle when the engine started misfiring and popping through the intake. At our Hamilton workshop, removing the rocker cover revealed bent and broken pushrods.The damaged parts were easy to see. Finding out why the engine still would not run properly took the investigation further.The problem continued after replacing the pushrodsWe fitted replacement pushrods and checked the camshaft and lifters, but the running problem remained. Replacing the v...

BMW coolant connections spotted during a service

A BMW came into our Hamilton workshop for a service. While checking it over, we noticed deterioration around the coolant-line connections that needed attention.The photos show the areas that caught our eye. The coolant lines had not been replaced at the time of this write-up.It is a useful example of why the condition of the parts under the bonnet matters, even when a car is booked in for routine servicing....

Air Conditioning Not Cold? Common Causes on BMW, Audi, and Mercedes

First hot day of the year, you jump in the car outside your place in Chartwell or on the way in from Rototuna, crank the air con up, and get nothing but lukewarm air or a weak trickle from the vents. It's one of those problems that seems to show up overnight but is usually the result of something that's been building for months.On BMW, Audi, and Mercedes especially, air con systems are more complex than most, with electronically controlled compressors and climate control units that don't always ...

Grinding, Knocking, or Squealing? A Quick Guide to Common Car Noises

A grinding noise when braking almost always means the brake pads have worn down past their friction material and metal is now contacting metal, which also means the discs are likely being damaged in the process. A grinding sound when changing gears in a manual points to clutch or gearbox wear, and it's worth getting looked at before it turns into a bigger repair. Either way, grinding is one of the noises worth acting on quickly rather than waiting.A knocking noise from the engine, especially one...

WOF Failed? The Most Common Reasons Cars Fail Their WOF in Hamilton

Tyres are one of the most common reasons cars fail a WOF in Hamilton, and it's usually not because people don't know their tyres are worn, it's because tyre tread wears down gradually until it's suddenly below the legal minimum. Cracked or perished tyres, unsuitable tyres and an unsecured spare wheel can also need attention. It's an easy one to avoid by checking tread depth every few months rather than waiting for the WOF to tell you.Lights are another regular failure point, not just dead bulbs ...

How Often Should You Service Your Car in New Zealand? A Simple Guide

The right service interval depends on your vehicle, its manufacturer’s requirements and how you use it. Speedwell generally recommends servicing every 12 months or 10,000 km, whichever comes first, with shorter intervals for some vehicles and driving conditions. Check with us if you are unsure what applies to your car.The other big factor is how the car is actually used. If most of your driving is short trips around town, stop-start traffic, or towing, that counts as "severe" use even though i...

Dashboard Warning Lights Explained: Electrical vs Engine vs Just a Reminder

Modern cars pack a lot of warning lights onto the dash, and it's not always obvious which ones mean pull over now and which ones mean book a service when you get a chance. Here's a rough guide to what the common ones actually mean, grouped by how urgent they are.Red lights mean stop as soon as it's safe to. The oil pressure light (an oil can symbol) means the engine could be seconds away from serious damage if you keep driving, so pull over immediately and don't restart until it's checked. The t...

How Much Does a Pre-Purchase Inspection Cost in Hamilton?

If you’ve been comparing prices for pre-purchase inspections around Hamilton, you'll have noticed the prices vary more than you'd expect for what sounds like the same service. Some of that comes down to what's actually included, and it's worth understanding before you pick based on price alone, because the cheapest option isn't always the cheapest option once you factor in what it misses.At the lower end, some inspections are really just a visual check and a test drive, done in a driveway or c...

Slipping Gears or Rough Shifting? What It Means for Your Automatic Transmission

Pulling away from a stop on Ulster Street or accelerating onto the expressway and your automatic feels like it hesitates, slips, or shifts harder than it should? Transmission problems are one of those things Hamilton drivers tend to put off getting looked at, because the car still moves and the fix feels like it'll be expensive. Sometimes it is a big job, but plenty of the time it's something straightforward if it's caught early, which is exactly why the early symptoms are worth paying attention...

Buying a Used Car in Hamilton? What a Pre-Purchase Inspection Actually Checks

A pre-purchase inspection can help you understand a used vehicle’s condition before you buy. It can identify visible wear, faults and signs that further investigation is needed, but it cannot guarantee the vehicle’s future reliability. Here is what an inspection can include.A proper inspection starts with a full underbody check on a hoist, not a five-minute look with a torch. We're checking for rust (especially around sills, chassis rails, and suspension mounting points, which matters more i...

Why Pops and Bangs Are Bad for Your Engine

That crackle-and-bang exhaust note on overrun is one of the most requested tunes we get asked about. It sounds great, and we get why people want it. But before you ask for it on your car, it's worth understanding what's actually happening every time it fires off, and what it's costing your engine in the background.What's actually causing the noiseA "pops and bangs" or "burble" tune works by deliberately sending extra unburned fuel into the exhaust when you lift off the throttle. The ECU is remap...

Car Won't Start? Battery, Alternator, or Starter — How to Tell the Difference

Nothing's more frustrating than turning the key on your way out the door in Hamilton and getting nothing back, or a slow crank that just won't catch. Whether you're parked outside your place in Chartwell, in the work carpark on Anglesea Street, or at the New World in Rototuna, a car that won't start usually comes down to one of three things: the battery, the alternator, or the starter motor. They're easy to mix up because the symptom looks the same from the driver's seat, but the fix (and the co...

AdBlue Warning Light On? What It Means for Your VW or Audi Diesel

Seen an AdBlue warning pop up on the dash of your VW or Audi diesel, maybe with a message counting down the kilometres left before the car won't restart? It catches a lot of Hamilton diesel owners off guard, especially if they've never had to think about AdBlue before. The good news: it's rarely something serious on its own, but it does need sorting quickly.AdBlue (also called DEF, or diesel exhaust fluid) is the fluid your VW or Audi's SCR system injects into the exhaust to cut NOx emissions. R...

Brake Judder When Slowing Down? What It Means for Your BMW, Audi, or Mercedes

Feel a pulsing or shudder through the steering wheel or brake pedal every time you slow down for the lights on Anglesea Street, or coming off the expressway at Te Rapa? That's brake judder, and on European cars it tends to show up earlier and more noticeably than on a lot of other vehicles.It's a common one we see across BMW, Audi, Mercedes, and VW models in Hamilton, especially on cars doing a lot of stop-start city driving or regular towing. The good news: it's rarely a safety-critical fault o...

Why Won't My BMW, Audi, or VW Start? Battery, Immobiliser, or Something Else

You go out to your BMW, Audi, or VW parked outside your place in Hamilton East or in the work carpark, turn the key or push the start button, and nothing happens, or it cranks but won't catch, or the dash lights flicker but the engine stays silent. It's one of the more stressful car problems because it can strand you on the spot, and on European cars there are a few different systems that can be behind it, not just a flat battery.Working through what's actually happening (cranks but won't start,...

Whining or Grinding Noise on Cold Start? What It Means on a VW, Audi, or BMW

You start the car first thing in the morning (heading out from Flagstaff or across town on Wairere Drive) and there's a whining or grinding noise for a second or two before it fades. It's a different sound to a simple rattle: higher pitched, more mechanical, sometimes with a bit of a whir to it. On VW, Audi, and BMW engines, this is often the timing chain tensioner asking for attention before it becomes a bigger problem.It's a noise that's genuinely easy to write off, especially since it usually...

Clunking Noise from the Front of Your European Car? Here's What It Usually Means

You're going over the speed bumps on the way into the mall carpark, or turning into your driveway in Rototuna, and there's a distinct clunk from the front of the car, sometimes over every bump, sometimes only on tight turns. On a European car past 60,000km, this is one of the most common complaints we hear, and it's almost always coming from the front suspension.It's easy to put up with for a while since the car still drives fine day to day, but a front-end clunk is a wear-and-tear issue that on...

Oil Leak from the Valve Cover? What BMW N20/N52/N54 Owners Should Know

You pop the bonnet on your BMW after noticing a burning smell, or you spot oily residue creeping down the side of the engine while it's parked outside your place in Chartwell or in for a WOF on Anglesea Street. If your BMW runs an N20, N52, or N54 engine, a valve cover oil leak is one of the most common issues we see, common enough that most long-term BMW owners in Hamilton will run into it eventually.It's rarely an emergency in the first few weeks, but left alone it goes from a minor seep to a ...

EPC Light On? What It Means for Your VW or Audi

You're pulling out of the driveway in Hamilton (maybe heading down Peachgrove Road or onto the expressway) and the EPC light comes on the dash, sometimes alongside a check engine light, sometimes with the car suddenly feeling gutless. EPC stands for Electronic Power Control, and it's VW and Audi's system for managing throttle, traction, and cruise control electronically. When it lights up, it usually means the car has detected a fault and pulled back engine power to protect itself.It's a common ...

Coolant Smell or Leak? What It Means for Your BMW, Audi, or Mercedes

You hop in the car in Hamilton and catch a faint sweet smell through the vents, or you spot a puddle under the front of the car after it's been parked overnight, maybe outside your place in Rototuna or in the work carpark on Anglesea Street. On a BMW, Audi, or Mercedes, a coolant smell or leak is one of those things that's easy to put off, especially if the temperature gauge still looks normal. It shouldn't be ignored.European engines run tighter cooling tolerances than most, and a slow leak tod...
