Hi Norman

You need to test the glow plug system , the plugs may be working but may now be slow and weak .

There is a lot of work involved checking the glow plug system if you don;t have the right tools and scan tool .

Do the following first thing in the morning .

Switch on the ignition ,don't start.then switch off after 10 seconds ,
do this four times then try and start ,if she fires up a lot easier than before then have the glow plugs replaced .

If still the same, you will need a good scan tool to check the management system.

Do this then get back to me if needed with the reply box below
