• Q . Vauxhall trailer electrics 15 Sep 2003 (Forum)
  I have just purchased a Vauxhall/Opel Zafira add-on trailer wiring loom that connects to the rear light cluster looms, battery, and 12N socket. As part of the install there is a \'Flashguard\' relay that plugs into trailer loom at the rear of the car . When testing the indicators, with the trailer plugged in, everything seems OK but I expected to hear a buzzer but there is no audio warning .

I'm beginning to warm to the little fellow who threw up on the Motorshow programme, he's quite a cheeky chappie...
• Mondeo Diesel Cold Start 30 Oct 2002 (Forum)
  (After a bit of fiddlng with various things by the garage, the car did start, but nothing was done to fix the problem) c) Warm starts - no problem. The battery is new and ok. Factory fitted alarm / immobiliser is working normally. There are no warning indicators on the dashboard. Plug heater light works normally ie switches off after a few seconds - double heating causes the light to switch off noticeably quicker on the second iteration.
• Do we really need or want this level of complicati 6 Dec 2001 (Forum)
  At the core is an ECU from Motorola?s PowerPC family. Each transmission produced at Saarbrucken goes through a battery of tests to establish its unique characteristics, which are then programmed into the chip, *creating a bespoke ECU for that specific transmission* . ?It?s the brain of the system? says Manfred Bek, senior manager control systems for ZF Getreibe car transmission division.?
• Things you notice 1 Dec 2001 (Forum)
  If there is front end damage the bill would be expensive, GM have tucked in the fan and the turbo intercooler right behind the bumper member and the compartment must be expected to run hot since there is a neat insulating jacket over the battery. The "deluxe" front seats have a strange panel at the front which is free to slide forward about several inches, it looks like it's meant to support your leg further towards your knee but it seems more comfortable if left alone.

• Car and bicycle tyre pumps / inflators and gauges 2 Jul 2024 (Forum)
    As I live in a flat, I cannot use a direct plug-in type 'inflator', but could use (if they are made) a solely battery-powered one if a high quality 'manual' foot pump isn't available.  Given my car's predilection for going through car batteries, I'd rather not rely on one that you have to plug in to the car for power.
