Vauxhall Zafira/Meriva rear door locked with child lock on!

Fault with the rear door wiring loom on a Zafira  B series
The  external loom touches the rear door skin the wires are prone to breaking
The problem was a rear door where the central locking wires had broken and the door wouldn’t open and the child lock was on The solution was
Remove door panel from inside without opening the door.
Checked continuity from door A post to lock mechanism.
Stripped back wiring loom
Repair the broken wire and solder.(Sounds easier than it was!)

Rare Alpha Romeo 1.9 CDTi @London Avenue Garage.

The Alpha GT carries the same engine as the Vauxhall`s we know so well.This CDTi experienced not only a head gasket replacement (from over heating) but on closer inspection we found the camshaft pulley woodruff key broken inside the camshaft pulley.This vehicle experienced poor staring and misfiring.The ECU has control over the injectors , altering the pulse width – the length of time injectors are held open to provide a rich or weak mixture as needed . The fuel air mixture is constantly varied by the ECU . To do this it gets it’s information from the sensors like MAF / coolant temperature sensor etc .However if the basic timing is not aligned then the vehicle will and did experience poor starting.This vehicle had a full recondition of the cylinder head,head gasket set with cylinder head bolts,new timing belt kit,water pump,oil and filter,antifreeze and camshaft and crankshaft pulley replacement.This was all carried out at our garage in Northend Portsmouth PO29BT

Vauxhall Zafira/Vectra/Astra CDTi Swirl flap,EGR & Inlet manifold. London Avenue Garage Portsmouth PO29BT

Zafira CDTi Inlet manifold

Zafira CDTi Inlet manifold

This picture shows the broken swirl flap from a Vauxhall Zafira,the swirl flap is located on top of the manifold near the glow plugs.On removal of the manifold we found the swirl flaps completely seized.This vehicle experienced a lack of power and engine management light.Unfortunately when the Egr valve is stuck open it can allow these fumes to start coating the swirl flaps inside the inlet manifold and the first many people know about it is,either the engine managment light(EML) comes on or while doing routine maintenance they see the external swirl flap bar that connects these flaps together has fallen off.(its on top of the engine under the injection pipes)

 

Egr valve gums up with exhaust fumes and needs to be periodically removed and cleaned.
