HI ALL, DOES ANYONE KNOW A EXHAUST FABRICATOR IN THE RUNCORN AREA WHO CAN CUT OUT AND REPLACE THE FLEX SECTION ON MY EXHAUST, I HAVE AN 08 PLATE SUPERB 1.9TDI

THANKS

Try posting it in the General Car Chat section, more likely to get a reply.

Pity you don't live 150 miles farther south or I'd recommend someone locally who did the same job on my 2.0 2 weeks ago. Cost me £150, inc. the new flexi pipe and half a days labour, but still a hell of a lot less than £518 +VAT for a new Cat (I don't know where the flexi joint is on the 1.9, but on the 2.0 it is the front part of the cat immediately after the turbo)

Hi my flexi pipe has just gone on mine 2007 2.0 tdi pd, skoda quoteing £600 quid for it, am looking for a cheap fix as am sick of pulling money out on it now, what do they do, chop the flexi out and put a weld a pipe in or is there anywhere u can get the flexi without the cat, cheers

You can buy sections of flexi-pipe. My 1.9Tdi Passat had this issue. I took it to a local guy who bought a suitable flexi and cut/welded it in.

You can't put a solid pipe in it's place, you would get lots of vibration and probably a broken exhaust fairly quickly.

Most (small/good) exhaust places will have a catalogue with various exhaust components in. Failing that, You can get an after-market cat for more like £200 ish IIRC.

Not what was being asked for, a proper exhaust fabricator will have access to the correct quality and sizes of flexi parts, but the best bet is to get hold of the correct flexi repair section from someone like www.senioraftermarket.co.uk I sorted a Polo 9N exhaust using a bit bought from them, you do need to acurately check which size you need and buy the top quality version. In my experience, an exhaust fabricator will only get access to a limited range of sizes and will make do with that, usually that means that the diameter or flexi length is wrong and can lead to resonances at certain revs or the exhaust touching the chassis and making noises under certain conditions. I trusted my local exhaust fabricator and he kind of got let down by his supplier, so my wife's car ended up getting a crap job done on it, it was only then that I bought the exactly correct sized part from senioraftermarket and went back to the exhaust guy and got him to change it - then the car was as "good as new".

Sorry for late reply, only just re-spotted this thread.

As said above, it has to be flexi-pipe.

One problem is that the O/D of the fixed pipe from the turbo is smaller than the O/D of the "pipe" at the front of the Cat. Only about 5 mm apparently, but a bit too much to just rely on weld filling the gap. Andy took both parts to a nearby specialist exhaust parts supplier and after some head scratching they came up with a short section of stainless pipe that just fitted inside the Cat end to use as a reducer. This has effectively reduced the bore of the entry to the Cat, but generally agreed that it wouldn't affect either the operation of the Cat or the performance.

The reason it took so long was simply that the Cat and the broken section of pipe had to be removed, the broken ends cut off, the adapter welded in place, then the whole reassembled with the new section of flexi pipe slipped in and lined up.

This was TIG tack welded to locate it, then all removed again to weld the seams (impossible whilst on the car of course)and then all reassembled.

All in all I can understand why it took him 5 hours to do it, but it was worth every penny to avoid the £600+ for a complete Cat replacement.

Interestingly prior to the repair my consumption had dropped to around 43 mpg. I had put this down to the cold weather, since being fixed it's back up to around 48 mpg.

I told him this when I saw him at the New Year, and we sort-of agreed that it was probably due to it overfuelling due to the sensors reading that the car was running "lean" due to the additional air being drawn into the system. (I say sort-of as it led to some heated discussion in the pub)

The assembled populous also agreed that running it with the broken pipe and the consequent overfuelling would probably shorten the life of the DPF if left too long, but after a few pints these sort of theoretical discussions never prove anything
