I know better than to reply really BUT your profile says manual CDTI rather than auto? If it is an auto then I'm sorry I don't believe you, unless you have an extremely rare 6 speed auto box

I wish there was an extremely rare 6 speed auto box

It is a manual, but my point about mpg had relevance.

It is possible to get incredible mpg figures from the manual diesel.

You have to drive very gently however.--

I did a 50 mile round trip over here in France where we don't have traffic.--

Below is a pic of the readout I got at 45 mph speed for the whole trip.

A small but seemingly common issue.

The egr pipe had fractured splitting where it joined at the bypass.

To combat this I've now fitted an alternative egr bypass instead.



It gives you plenty of options, like full pipe removal off the manifold and so on, but I've a egr cooler so I fitted the round blank instead.

Solved my problem but after 200k miles a damaged pipe is a small issue.

I always find the egr bypass to make the Diesels smoother, more free review and so on. I've even tried a cleaned out inlet with original working egr and I just can't find the benefit of not fitting a bypass.

My experiences obviously on several 75 Diesels now, manual and auto.

So many of the bypasses are badly made and even when new & don't seal properly especially at the corrugated joint with the jubilee clip.


A major supplier on here included too

I've fitted several recently and noticed consistently the type with the penny blank fitted seem to all be about a cm off place that the ones I've saw for years.

I fitted an EGR bypass a couple of weeks ago and then broke down on the motorway last night

The car had an engine fault light (I think that's what it said) and would only run at about 1400 revs.

Looking under the bonnet, the EGR pipe had split and was blowing hot gasses onto the inlet manifold. You can see from the photo that it's melted some of the plastic.

I think it's melted some of the wire there too, which is the MAP sensor I think. I assume that's what was causing the engine fault.

I bought this type of bypass because I'd read that it puts less stress on the pipe - and I was careful when fitting the blanking plate. I guess the pipe was just getting weak and me messing with it has finished it off.

Hi Alistair.
I have reported a few times now that those EGR bypass are not good to fit, they must have the support on them other wise the pipe will flex with vibration and end up splitting as yours did.

It as most likely damaged the wiring to the fuel rail sensor, the MAP sensor is on the other side of the manifold.

If you are going to fit a bypass EGR then use an original one gutted.
1

With the support for the rest of the manifold egr exhaust.
2

There are one out there not original with the support which are much better than the one that is fitted to your car, such as this below, but still not as good as having an original gutted one in my opinion.
3

4

These are the manifolds cleaned out which i exchange at the Nano meets, some have the EGR gutted others stay original.
5

To late for you now though, as you know you can 99.9% always find a solution on here.

I have a few of these if you wanted to revert back to original, but it's not an easy job to remove and re-fit the exhaust section.

Thanks Steve,

I guess I need to start by getting the EGR pipe off and then I can either fit a blanking plate or one of your pipes. I have seen a how-to on here somewhere, so will dig it out. Everyone says it's not easy though, so I'm not looking forward to that.

I'm not sure what to do with the wiring, I guess I'm best to get a second-hand plug from someone with a length of the wiring attached and solder it onto the existing wires.

I will need a new manifold, so will give you a shout for one once I've got the above sorted.

Cheers,

Al

Hi Al.
looking at your photo again, it seems you may have got away with the manifold being damaged, as the section for the grommet has melted nothing else, as it actually melted the fuel rail sensor plug wiring ?
