To gain quick access to this site

AP Autodiagnostics Ltd provide an injector removal service for the latest Common Rail Diesel engines. This is a well known and documented problem caused by the reaction between aluminium and steel injector components, resulting in the injector becoming tightly seized into the cylinder head and therefore difficult to remove. 

See our Seized injector removal service pages for more details.

AP Autodiagnostics Ltd. can provide a diagnostic service for fault finding on vehicles manufactured for use in the European Union after 2001 (petrol) and 2004 (diesel), enabling us to take advantage of the OBD, OBDII and EOBD diagnostic protocols.

Our highly trained and qualified staff can using the latest top of the range diagnostic tools, offer dealer level service, at independent garage prices. Specializing in the latest diagnostic aspects of vehicle repair, allows us to keep on the cutting edge of both petrol and diesel engine development and other associated vehicle electronics.
