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.

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...

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,...

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...

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...

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 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 ...

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...

If you drive a car with the EA888 engine (common across the A3, A4, Golf, Passat, and Tiguan ranges), this is one of the most talked-about issues in owner forums, and for good reason.It's easy to dismiss as "just a cold start noise," but timing chain issues on the EA888 are well...

This is one of the most common (and most worrying) things DSG-equipped VW and Audi owners notice, and it's worth understanding what's behind it before assuming the worst.We see this across the full range in Hamilton: Golfs, Passats, Tiguans, A3s, A4s, and Q5s.What's usually behind itMechatronic unit or clutch pack wear: judder most noticeable pulling away from a s...
