I've decided not to remove DPF as yet and check all connectors first...
This is what I've done at the weekend to try and cure the problem:
- Blew all connectors I could find under the bonnet with air compressor
- Removed and blew ECU connectors with air
- Checked all fuses in both cabin and engine compartment using multimeter
- Removed battery, cleaned and vaseline'ed its terminals and battery clamps.
Sadly, after all that time spent on the above activities, there is no improvement and I still get the same warnings message on the dash
On the positive side, I've managed to replace both DRL bulbs
Any other ideas what else I can do?
I'm desperate to get this sorted as I'm planning to drive abroad in a month or so.
