hi 2day i found leak under bonnet ,looks and smell like diesel , .for me its leaking under fuel filter .skoda superb 2.0 tdi 150ps .2morrow i will contact service centre because 2day its closed . Car only cover 21k miles. 

Please answer if someone had the same problem

Check if any diesel has contaminated the auxiliary drive belt.

 

If so, get the belt changed.

The hose on the top of the picture (connected to fuel filter housing) seem to be greasy, as if the leak coud come from here...

Otherwise, check that bolts on the fuel filter cover are correctly tightened. 

Thanks Bap33 ive double check all pipes and hoses , its wet under filter , dont know how its looks like below , today i spoke with car dealer and they arrange repair in next two days 😞

Maybe its a good idea to check this bolts 

A couple of years ago a work colleague with an Audi A5 that's got a similar engine and filter came to work after his car was serviced and found diesel was leaking as they'd fitted the filter incorrectly.  He called them out to work and they refitted the filter correctly and had to take the car back to clean the mess under the bonnet.

Thanks guys , its fixed now , filter seal was done incorrectly when it was changing , they change filter install new seal and clean out mess under bonnet :))
