EGR flexi-pipe: Exhaust Fumes In Cab, Hissing From Engine Bay.
- Thread starter Tourershine
- Start date
I'm going to be very surprised if it doesn't turn out to be the pipe I mentioned earlier in the thread. It's the exact description of the issue I had, and an easy fault to find if you know how to look. Shame you don't live closer to me.
Thanks for all the help guys. Van is only approx 6 months old. . . 5000 miles. I went on a drive with the technician today, but I'm not massively convinced by his comments. He said it's "totally normal" for a cold engine and then went on to say that it was the "turbo actuator" and then said "it's the solenoid waiting for the oil to get through". Does that mean anything to anyone?

@dennismo did you manage to get this sorted? I've got the exact same noise from 1500rpm to 2000rpm with light throttle in 4th and above.
I don't know if I'm going mad but I'm sure it wasn't there 600 miles ago (when I picked up the van).
Mines done 8k miles, 150bhp 6 speed.
Cheers!
Have you tried my previous suggestions earlier in this thread, lifting the bonnet and getting someone to blip the throttle? It's pretty obvious if you stick your head round the back of the engine.
Yeah tried that, checked the intake hoses before and after the charge cooler and the egr pipe, all look good!
Maybe it was always there and now I'm just listening for it!?
It's most noticeable in 6th around 60-70mph gently accelerating, full throttle and it goes... Is there a recirc on these? Could be that?

Never got it sorted... partly just as life has been a bit hectic since then. As @Loz said, it felt like the technician had no idea. I've been meaning to go back and ask to drive another 150 to prove that it's "totally normal" but haven't got around to it...
The pipe in question is not visible in the engine bay, it's right at the back of the block. I only found the leak by putting my hand round the back (no comments please) and felt the air pulsing. Then used my phone to take loads of pics until it eventually focused up on the crack you can see in my picture.
I assume it cannot be the same issue, because it was pretty obvious.
Useful to read through the description of problems here as I encountered exactly the same yesterday on ‘66 204. Hissing upon low rev acceleration or blipping accelerator plus strong emission smells around front of van. New noise, never encountered so knew something was amiss. Called VW assist who sent AA and engineer immediately tracked problem to cracked EGR pipe. It’s going back to Jct Sheffield this week.
@SirVelo75 - I'd be interested to know how you get on. It was JCT Sheffield that told me that it was the "turbo actuator" and nothing to worry about 
Going to check that today, drove a 150 shuttle yesterday to compare and the engine is literally 75% more quiet so either mines got a hole in or that's just what a kombi sounds like with less insulation etc??

Update: JCT Sheffield couldn’t book me in ‘til this Thurs so will post again then@SirVelo75 - I'd be interested to know how you get on. It was JCT Sheffield that told me that it was the "turbo actuator" and nothing to worry about
OK can't seem to find any leakage on pipework but generally the kombi sounds more agricultural even on tick over with the bonnet open comparing both vans, the kombi is louder? Different engine mounts or something? The sound insulation looks identical apart from the battery cover? Interesting either way!
Update to add, changed the oil today, its done 9k on original oil, refreshed with castrol and its a lot quieter and sounds less like a diesel now!
Just got to sort the boost noise out, maybe take a trip to the dealer to see if there's anything obvious I've missed...

Van went in to JCT Sheffield today. Tech agreed that what I’d described was thought to be the corrugated EGR pipe as described earlier this thread. Interestingly, the part has been superseded by a modified version with more corrugations presumably to increase tolerance to flex and breakage. Dealer agreed to replace with new pipe under warranty and all sorted. Weird noise has gone, as has stench of emissions in engine bay and cab too. Happy
Where can I get the pipe from please
