Grand Scenic 1.6 Dci 130 split pipe

[haymaker2k]

Hi,

I have a Scenic 1.6 Dci 130 that has developed a slip in the exhaust pressure sensor pipe. It is the rubber part at the tip that joins the metal pipe to the sensor itself, it has a bent in it.

I have tried to get a replacement from Renault but they appear to only supply the complete pipe and sensor for over £100. I don`t want to spend that much if I can help it as its only a the rubber that has gone. Can this be purchased separately or does anyone have a suggestion for a DIY fix?

Thanks in advance,

Adrian

Hi, and welcome.
Could you post a photo of the split part?
Sounds like something that should be able to be replaced inexpensively.

Thanks for the reply. Its the rubber elbow at the top of the pipe labelled 4 on this pic:

Here is a photo of the split, bottom right. Hard to get to as its at the back of the engine.

I was thinking of just getting some new pipe but its an elbow and takes the heat from the exhaust so not sure it I could get something to do the job.

Did read while searching that someone put a straight pipe on it and modified the bracket but not sure how easy that would be.

It's quite a distance away from the exhaust manifold (the metal pipe run), and the pressure sensor won't be being subjected to huge heat, I guess. The metal pipe will be dissipating most of the heat.
Try a motor factor for a piece of elbowed 'rubber' pipe of suitable diameter; they're bound to have something you can cut a small section from.

Failing that perhaps Pirtek or somewhere similar would be able to help.

Or even something like this from eBay.

Silicone hoses tend not to like very hot conditions; fine for air ducting and coolant, but not at their best on/near hot-spots. Conventional reinforced 'rubber' will fare better, if you can't find any dedicated high-temp hose. Pirtek a good idea; you might even get something externally braided.

thanks for the suggestions. Will have a try of taking the pipe off to get the exact size of the section that need replacing.

Just an update, I purchased some high spec fuel line 8mm and it appear to be holding. Could not get the metal pipe off from the manifold as the access was too tight but attached the fuel line to the top with jubilee clips. Think the 8mm was a bit too big as had to tighten the clips up a lot to get a seal, but I think the next size down (6mm) would be too small.

Glad you've got it sorted. It's always the awkward pipe sizes that you find!
