Golf 1.6 diesel help

[Darrell]

Gents,

One of the guys at work has a 62 plate 1.6litre diesel Golf.

A warning light came on the dash and has been traced via a code reader to read as 'cylinder 4 glow plug circuit/open'

Any ideas please.

Glow Plug 4 has failed, the heating element is open circuit, i.e. broken.

Obviously needs to be replaced. Is it worth doing all 4 or is that a waste of time and money?

Depends on car age , mileage and number of cold starts. At 4 years old with average use I would be inclined to do all four. In general the longer they are left in the more difficult eventual and inevitable removal.

If the inlet manifold etc. has to be removed for access to the plugs (which is the biggest cost on the job), then get all 4 done.

When I bought glow plugs for the E250D , they were something like £1.20 each for Beru ones from Eurocarparts .

It would be silly not to replace the lot - has anyone ever replaced ONE spark plug ?

On engines like the 616 or 602 with good GP access, I treat them like light bulbs - i.e. same variable lifespan.

605 and 606 - usually a horrid job, manifold needs off, and they carbon up on the shanks.

CDIs with the thin GPs?
All I've removed so far came out clean, no thread problems. Not what i expected...
