Hello and HELP! Ok I have a 1.9 TDi Mk5 Golf, for a while I had a whistling noise coming from the engine which soon turning into a whooshing noise! At MOT time the mechanic had a look to where the noise was coming from and found the EGR flex pipe has a crack in it, its the bottom pipe, which makes sense as the engine now has a covering of soot on it! found a couple of part numbers one being this Lower pipe OEM part number: 038-131-521-CC but cant find it on the old interweb, where is best to get VW parts? other than the dreaded VW garage and being totally ripped off! First thing! where the hell so I get one from? I have searched and searched could anyone please point me in the right direction? Also today as unfortunately I still have to drive the car even though it sounds like a giant noise making machine, was on the motorway slowly accelerating up to 60 or 70 and the noise stopped and there was an instant loss of power, like the turbo had decided it didn't want to play any more. Now the car still runs at the min but the turbo isn't playing at all. I have done some searching on this and it appears that more than likely due to the cracked pipe there is an incorrect boost from the turbo and so the computer is deactivating the turbo, and once I have restarted the car this will be ok, but it will keep happening so i need to do something ASAP! Obviously I need to replace this bloody pipe and hopefully the new problem today will go away! all help appreciated with thanks
The part no, is actually 028 131 521, according to Vagcat. No price available though. Probably about 20-30 at a guess.
the part number is correct 038131521CC shows up in etka as being the connecting pipe for wide range of VWs about 60, but my price list is a bit outdated btw, also buy 038131547A and 069131547D those are the proper OEM gaskets, about 3 each why don't you take the pipe off, take it to a local welder and see what he can do about it
it's not a flexi pipe but solid, with a flexi effect for some give in it during fitting / noise management? unless damaged, I'd say gasket or just loose - even more suspect if the turbo/EGR cooler has been off/replaced
hi guys thanks so much for your help here i was considering taking it off and going the welder route, went to VW and they didnt seem to know what pipe it was! but the one i think it was came out at 85!
think i have found the part but tis is USA!! need to find this bad boy in the UK http://www.idparts.com/catalog/product_info.php?manufacturers_id=32&products_id=1422 another question i have seen popping up everywhere is blanking the EGR off? this a good idea?
A properly functioning EGR does not cause any issues or loss of power, though if I could find that pipe very cheap at a breakers i'd blank, but there may be a fault code because of it
thats why I didn't mention it, if you get a way to disable that function on the ecu, you can take all that egr stuff out. can you take a picture of the leak and post it here?
mk5s need a remap to cut block off EGR, or warning light comes up that part is the one, never seen one split - only loose
this is defo split! i will try and get a piccy of it, have messaged a couple of people on ebay who are breaking MK5 TDi's in the hope they know what im on about and they have the part!! from what i can tell its not a hard job to replace it? just a pain finding it thanks for your help so far guys
