Had a similar nightmare on Sunday to a similar post on this page where I was accelerating away from a roundabout and suddenly loss of power and massive cloud of black smoke poured out the back
I assumed worse ie Turbo gone and drove/chugged to nearest lay by and called RAC.
RAC Bloke new instantly what it was and pushed bottom hose back on stating a clip was missing but to give it a go and see how far I got... I got about 5 miles then it went again
3 attempts later and RAC bloke said upto you but if you are happy to drive without pipe on then carry on and I'll follow you home (about 40 miles) he would have put me up for recovery but was a 2 hour wait and I had wife and baby in car (both kicking off)!
Anyway I was told that clip number 5 (retaining clip) on diagram below was missing so I have ordered this along with number 3 (seal) from VW.
My questions are...
Is this a common problem ?
Am I likely to find or should I check anything else whilst fitting new clip/seal ?
What is the best approach to replacing the clip ? I'm guessing it will be best to remove the plastic cover under the engine to access the pipe.
Any pointers much appreciated
cheers
