Hi all,
I have just noticed that diesel is leaking right underneath the bonnet when the van is in motion.
I am not a tech person, so how much roughly will it cost to get it fix at a garage?

Don't just read and ignore, please reply if you know something .

u need to find out where its leaking from might be from filter housing which is common

Try tightening the white knurled plastic drain plug under the filter housing-better still remove, check the washer has not fractured and wrap some PTFE tape round the threads before retightening.

Thanks. It was a split hose.
