⚠️ PORSCHE TAYCAN – PARKING BRAKE FAILURE

Check your brakes before a small problem turns into a very expensive repair.

This Taycan Turbo S came into our workshop with a parking brake issue. Once the rear brakes were dismantled, we found significant damage.

The parking brake shoes had been incorrectly adjusted and were constantly contacting the inside of the brake disc while the vehicle was being driven.

The result:

* Parking brake shoes severely overheated and corroded
* Friction material breaking away from the shoes
* One shoe had lost its friction material completely
* The exposed metal backing had been running directly against the brake disc
* The Porsche Ceramic Composite Brake (PCCB) disc was badly scored

And this is where a relatively small parking brake problem can become very expensive.

A replacement ceramic brake disc can cost several thousand pounds – for one disc alone.

The parking brake may be a small part of the braking system, but incorrect adjustment or a seized mechanism can cause serious secondary damage before the driver realises what is happening.

If your Taycan has a parking brake warning, unusual noises from the rear brakes, excessive heat, or you simply aren’t sure when the system was last inspected – don’t ignore it.

Porsche 911 (991) 2014 – when the obvious repair doesn’t solve the problem…

This Porsche 911 came to us with an unusual intermittent injector fault.

The affected fuel injector had already been replaced, and the wiring harness and electrical connections were thoroughly checked. Everything appeared to be correct – yet the problem kept returning.

The DME would sporadically stop controlling the injector, while storing injector circuit / electrical fault codes.

At this point, the diagnosis became much more interesting. With a new injector fitted and the wiring confirmed to be good, further testing led us to a component that is rarely the first suspect:

The DME – Porsche engine control unit.

Detailed investigation confirmed an internal electronic fault within the DME, intermittently interrupting the injector control circuit.

It’s not the kind of failure you expect to find every day. When a fault code points directly towards an injector circuit, the injector and wiring are naturally the first suspects.

In this case, however, the real problem was inside the engine controller itself.

New injector. Wiring checked. Fault still present. DME diagnosed.

Sometimes proper diagnostics means going beyond the fault code.

WORK IN PROGRESS — Porsche Panamera 4 E-Hybrid 2.9 V6

Another serious job underway at SG Porsche Specialists.

This Panamera Hybrid came to us with low compression on cylinder No. 2. After initial diagnosis, the next stage required removal of the complete engine and transmission assembly for further investigation.

Current work:
• Low compression — Cylinder 2
• Engine & transmission assembly removed
• Detailed mechanical inspection underway
• Root cause diagnosis before any parts are replaced

Modern Porsche hybrid powertrains are complex, but correct diagnosis comes first — especially when dealing with internal engine problems.

More updates to follow as we get deeper into this one.

Back to the golden era of diagnostics .

Nothing beats plugging a retro diagnostic tool into a legendary Porsche 964 Turbo.
No giant touchscreens. No endless menus. Just raw engineering and real mechanical soul.

These old-school systems may look simple, but they still tell the story of one of Stuttgart’s finest machines. Every fault code, every sensor reading — pure 90s Porsche magic.

Keeping classics alive, one diagnosis at a time.

Another Taycan has joined the repair queue. A Tycan 4S had a problem with its parking assist system; one of the front sensors was interfering with the entire system (no error codes). Another workshop attempted to repair a Tycan Turbo and caused a bit of a mess. We've already repaired and calibrated the air suspension, and the reversing camera and front radar are waiting to be calibrated.

Over 50 years of evolution, one spirit remains.

From the timeless charm of the Porsche 912 to the cutting-edge innovation of the Porsche Taycan, the journey tells a story of passion, performance, and relentless progress.

The 912 captured hearts with its simplicity and driving purity—lightweight, balanced, and unmistakably Porsche. Fast forward five decades, and the Taycan redefines performance for a new era: fully electric, instantly powerful, and engineered for the future.

Different generations. Different technologies. Same DNA.

And whether it’s classic or electric—we repair both.

It’s not just about where Porsche started or where it’s going—it’s about the legacy that connects them.

It's time to move forward and expand our specialization.
