X300 Headlamp Powerwashers


Following up on my report of last month, at the very last minute, while Brucie was at XJK having his front bumper refurbished for the second time this year, the X300 headlamp powerwash system was re-introduced to the market and Brucie was kitted out with a set of brand new head lamp power washers !!

Many people have asked me for these over the last few years, so if you are one of those who have been looking for them, visit:

X350 Park Brake Fault

While Brucie was at XJK, an X350 was brought in, displaying a ‘Park Brake Fault’ on the message centre.

When plugged into the SDD (Symptom Driven Diagnostics) reader, it diagnosed PARK BRAKE FAULT  ‘HALL EFFECT’ *

This usually indicates failure of the electronic park brake motor resulting in replacement of the offending article at considerable cost, in time and parts, as it normally involves dropping the rear subframe by 60 ml to allow access for removal and replacement of parts.

However, in this case, the code displayed indicated that the motor was not even receiving the signal, which led Ian Kelsall to believe that there was a wiring fault in the car – a not unusual problem with X350’s.

With the car on the ramp, the handbrake motor wiring loom at the rear of the car was examined and a wire was found to be chaffing on the underside of the floorpan. The damaged wire and witness mark can be seen in the pictures below.


This picture shows the mark on the underside of the floorpan (indicated by yellow oval) where the handbrake signal wire was rubbing

This picture shows the signal wire which was causing the fault, with insulation worn through to the bare wire

Ian cut out the offending damaged signal wire and replaced it; re-scanned the car, cleared the code, and test drove the car, all within an hour, leaving one very happy and satisfied customer who had saved the cost of a new handbrake motor and the associated labour!


*    The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879.

XJK had three other interesting cars on site while Brucie was there

One was this immaculate genuine low mileage E-type Series 3 Drophead, which has nothing to do with the bonnet in the background, which belonged to one of the other interesting cars on site!



Third of the three was the Ford Capri used in the Minder TV Series.

Did XJK overlook the fact that this wasn’t a Jaguar as Ford were former owners of the company,
and Arthur Daley (Terry McCann’s boss) almost always drove an XJ saloon?
