147 JTD turbo intercooler hose replacement
had mine wear through last week on the earth strap mounting stud (common fault) and started to billow loooaaaddddddsssss of crud out the back on acceleration - tried using self sealing silicone tape as a 'stop gap' (literally) but it just blew as well, leaving me with smoke and a whistle! Rang Autolusso and they just got a new silicone hose in (sexy purpley blue), which they fitted while I waited last night - quick blast up the road to clear the muck out the pipes and this morning everything back to normal - no smoke screen for other drivers to hit!
Hose thicker/firmer (ooer) than the genuine one, so should be more robust. Note that I ground down the offending mounting stud, but they can be moved if required....
