Hey there. Can any One Tell me the size of the flex pipe on the dpf/exhaust system on Skoda fabia mk2 1,2 TDI greenline .

I have to repair it, no need to by a new dpf system

 

 

The best plan is to get the car up in the air and take a few accurate measurements, like the pipe OD at both ends of where the flexi is fitted and the length of the actual flexi section of that "flexi section" as it will have a flexi part and tails, even measure the OD of the flexi itself.

 

There are a couple or more versions or qualities of flexi sections depending on where in an exhaust they are located, the one nearest the cat needs to be the higher quality due to the temperatures.

 

Hopefully things have moved from when I got a flexi replaced on a 2002 Polo back in 2005 or 2006, the first flexi my expert exhaust fabricator fitted was the next size or more up in diameter and the next size or more down in length of the actual flexi part - that was a total failure that I had to pay to get sorted out because I am not an exhaust specialist and so must have been wrong and there was no reason why that repair left that car with a serious exhaust resonance on the overrun and the exhaust touching the underbody when reversing up a steep driveway probably due to it now not having enough flexibility.

I recovered the situation by asking for someone on this forum to measure their original flexi section, then I bought the correct flexi repair section from Senioraftermarket and got that expert exhaust fabricator to fit it. Experts are not always good at doing things!
