Pads look new. Brakes can still bind.

DVSA data for April to June 2026 shows 26.75% of Class 3 and 4 vehicles failed their initial MOT. Brakes also account for over a quarter of dangerous defects in DVSA data.

The EV picture is worth a closer look. Analysis of 10 million UK MOT records by CarHunch, reported by Fleet News and Garage Wire, found that at an EV’s first MOT, 6.9% of brake-related failures involved corrosion or seizure, close to 6.6% for petrol cars.

Regenerative braking means the friction brakes do less work. Caliper slides can seize and discs corrode while the pads still look sound. A proper check looks beyond pad thickness and checks the slides too. Brake fluid still ages as well.

P0C2900 on a DQ381 (0GC) DSG7? It means the transmission control unit has detected implausible behaviour from the auxiliary transmission fluid pump, V475.

That could mean pressure is too high or too low, takes too long to build, or the pump is running outside its expected time parameters. Possible causes include a failing pump motor, an internal hydraulic leak, low or contaminated fluid, or a pressure sensor or control valve issue.

The code points to a problem. It does not identify the failed part on its own. Proper diagnosis matters. If pressure control is left wrong, extra strain can reach the gearbox’s hydraulic control system and potentially lead to more extensive mechatronic damage.

Tyres wearing on one edge? Changing them won’t fix it.

This Polo GTI is on our Hunter VAS 6292 alignment rig. We measure the geometry first, then advise.

Uneven wear is a symptom. Either the alignment is out or a worn bush is letting the suspension move. Fit new tyres without finding which, and they’ll wear in exactly the same place. You’ve paid for tyres twice and fixed nothing.

So we take the readings, inspect the suspension components that affect them, and tell you what actually needs doing. Sometimes that’s an adjustment. Sometimes it’s a part. Either way you’ll know why.

SOS or eCall warning on the dash? It’s not usually the main battery.

Most modern VW, Audi, SEAT, Škoda and CUPRA models have a separate backup battery behind the dash. Its job is to power the emergency call system if the car is in a collision or loses main power.

Like any battery, it wears out. Plenty of VAG cars are now old enough for this warning to start showing. Once that battery fails, eCall may not work when you need it.

If the message has appeared, get it checked and the battery replaced properly so the system works when it matters.

A Haldex fluid change on its own isn’t a Haldex service.

On Gen 5 units there’s no replaceable cartridge filter. Instead, there’s a fine mesh strainer on the end of the pump, and over time it collects sludge worn from the clutch pack. Draining and refilling the fluid does nothing to clear it.

Leave it blocked and the pump has to work harder to build pressure. Eventually the rear axle stops getting drive, often with no warning light. You’ll usually notice it in the wet first, when the car starts behaving like it’s front-wheel drive.

A proper service means removing the pump, cleaning the strainer, then refilling with the correct fluid to the correct level. That’s how we do it.

DSG feels jerky or hesitant when cold, then behaves once it warms up?

That is not something to ignore. The mechatronic unit controls hydraulic pressure and tells the clutch pack when and how firmly to engage. As components wear and adaptations drift, it can struggle to apply the clutch cleanly from cold.

The result is hesitation, harsh take-up or judder. Leave it alone and the wear can progress to clutch slip, more severe judder and eventually limp mode.

The photograph shows a DSG mechatronic unit disassembled on the bench. Proper diagnosis looks at the system, not just the symptom, before deciding whether the issue is pressure control, adaptation or clutch wear.

Your tyres are telling you something. Most people just replace the evidence.

This Polo GTI is on the Hunter alignment rig while we measure the wheel geometry before advising on any repairs.

If the geometry is out, or a worn bush is letting the suspension move, a fresh set of tyres will wear in exactly the same way. Same car, same angles, same result.

We check the readings, inspect the relevant suspension components and then explain what actually needs doing. Proper alignment starts with accurate measurements, not guesswork.

Get the geometry checked. Call the workshop on 0191 586 4148 to book it in. Monday to Thursday, 08:30 to 18:30.

Audi RS3 in with us this week for a sump reseal and service.

The second photo shows the oil residue around the sump before we started. A leak like this doesn't fix itself. Left alone, it gets worse, coats everything underneath and eventually turns into an MOT advisory or a low oil level.

The sump has been resealed properly and the service completed, so it's back to the standard an RS3 should be at.

Performance cars still need the basics done right. If you've spotted oil under your car or marks on the drive, get it looked at before it becomes a bigger job.

Call 0191 586 4148 or book at highvoltgarage.com.

DSG light came on, then went off?

The light may have cleared. The fault hasn't.

On the 7-speed wet-clutch DSG, it can be an early sign of a clutch position sensor failing. Ignore it and you're heading for limp mode and a mechatronic unit.

Get it read properly. 0191 586 4148

If you drive a 4Motion VW, a quattro A3, TT or Q3, a SEAT or CUPRA 4Drive, or a Škoda 4x4, there's a good chance it uses a Haldex coupling. On the Gen 5 units (Golf 7 generation and similar), there's no serviceable filter. What there is, is a fine strainer on the pump, and over time it clogs with sludge from the clutch pack.

Once that happens the pump works harder and harder until it gives up. When it does, drive to the rear axle stops.

There's usually no warning light. The car just starts behaving like a front-wheel-drive car. Wheelspin pulling out of junctions in the wet. Less grip than you remember. Most people put it down to tyres.

Draining and refilling the fluid doesn't touch the strainer. The blockage stays exactly where it was.

A proper service means removing the pump, cleaning the strainer and then doing the fluid service correctly. That's how we do it.

Not sure which system your car has? Give us a ring and we'll tell you.
