Hi all. Our zd30 common rail has lost power and we are stumped. Help!
At first we thought it was airtake so replaced the air intake ducting, then the intercooler, then intercooler and air intake hosing etc, then the vacuum hose which seemed to fix the problem for a few days but started playing up again over the weekend so replaced the mas sensor but still lacking power. Any suggestions cos we are stumped. Trying to avoid a mechanic but starting to think it's the only option. Thanks in advance.
