Porsche PIWIS Diagnostics in Essex
Factory PIWIS diagnostics for Porsche models from 996 onwards, including 2021-on vehicles, from an independent Porsche-only workshop in Harold Wood, Romford.
As a Porsche Partner Network member, we diagnose warning lights and electrical faults, and carry out high-voltage work on the Taycan and E-Hybrid models.
The scope of work and associated cost are confirmed with you after initial diagnosis. Labour is £100 + VAT per hour.
Credentials
The owner is Porsche trained, has completed Porsche in-house training, and spent nine years at a Porsche main dealer working at the highest level, with over 10 years’ Porsche experience in total.
Porsche Partner Network
We are part of the Porsche Partner Network, so we have access to the latest technical information direct from Porsche, and we can update your car’s online Porsche service history.
Programming and coding
We can update, modify or reconfigure systems to suit your needs, or restore full functionality after a repair.
Where a fault is identified, we can also carry out the necessary repair in-house, meaning you don’t need to take your Porsche to another garage after the diagnostic investigation. See our Porsche repairs page.
Models we diagnose
We carry out diagnostics on modern Porsches from the 996 and 986 onwards, including the 911, Boxster and Cayman, GT cars, Cayenne, Macan, Panamera and Taycan. We do not work on classic or air-cooled models.
Local areas
Our workshop is in Harold Wood, and we look after Porsche owners from Brentwood, Chelmsford, Upminster and Hornchurch, Ilford and Hainault, East London, Romford, Gidea Park and beyond. See our local areas
