Hi guys, first timer on here, love the look of the site, wonder if any one can help??
I have a 525tds 1995 model with about quarter of a million miles on the clock!
This car has never let me down, oil/filters changed over regularly, however it has developed a problem.
----here are the symptoms;
Erratic idle almost like a missfire when driven, goes like smoke, however there's plenty of that as well, as in clouds of black.
now I've cleaned the EGR when you disconnect the vac pipe, it runs marginally better, reconnect and give hard throttle there is knocking as in overfuelling. I've changed fuel/air filters, pump in tank putting out correct pressure
can anyone help ??
Thanks in advance Greg
