Glow Plug Controller Replaced ( 126543 miles )

On a routine scan for engine fault codes (everyone has a hobby…) I found a code related to the glow plug on cylinder 6. This can mean either the glow plug itself has failed or the glow plug controller. Since it’s recommended to replace both at the same time, and since the glow plugs require the intake manifold to come off but the controller can be changed with difficulty without removing the manifold, I decided to replace the controller first. I bought a genuine OE unit from Beru and you can see the old and new units in the photo below. Cost was £61.99 delivered.

The controller is located on the nearside of the engine on the side of the block behind the oil filter housing and a mass of hoses and cables. It’s a real struggle to access and requires patience and a bit of ingenuity plus plenty of cursing but it can be done!

Unfortunately this did not resolve my glow plug error code so I ordered a full set of glow plugs to fit another day…
