Re: Renault Laguna II - Phase 1 - Engines - Average MPG from 1.9 DCi Engine
03 120 Laguna II Duff Glow Plugs will not come out of aluminium block of engine, tried penetrating
and wd40 but danger of ceramics dropping into engine block! So, left in! Economy about 38-42mpg?... with these plugs not working - according to Renault and my independent mechanic but the risk of mending them is too great! I could not afford an engine rebuild! VW etc have special paint on plugs to stop this seizure to block and their plugs exit easily! Hey ho! I havn't given up yet. Mileage about 550 to 600 miles per fill up? IF the plugs were working then I think I would get another 5-10mpg as this was what I got before this problem!
Currently in Chillman's garage:
VW mechanic who is cool and honest!
