Hey all,

Just wondering if anyone knows of a similar piece of equipment to the Allard EGR delete that would fit a 159 JTDm?

For those unaware it replaces the EGR allowing freer flowing air plus no more oily tar like residue build up in the EGR & inlet manifold.

After having a new EGR & inlet manifold on my 159 and having just cleaned the EGR & inlet manifold on my Bora TDI, it got me thinking into ways to avoid future problems.

The Allard kit seems to be a popular modification for the VAG TDI community and costs less than a recon EGR so makes perfect sense to me!

I understand the EGR can be software deleted or blanked off / restricted but would like the thing removed completely. I suspect after removal it would still need to be 'ignored' by the ECU via a software delete?

Any ideas?

EGR:


Inlet:

There is a kit available for the 1.9/2.4, (easily found on ebay) but, is it that simple, would the lack of an egr valve upset the ECU? I owned a 156 2.4 20v and the egr valve stuck open, the ECU did not detect the fault but it was very evident upon driving the car. This suggests that it is not picked up......

I believe I have a faulty/sticking EGR at the moment, but no warning lights. So perhaps the ECU doesn't detect the thing not working? Perhaps it wouldn't detect that it had gone walk about?
If you EGR is stuck open the throttle response is very...very flat up until the turbo kicks in at about 2000rpm in the 2.4 20v. If it is stuck shut the only thing you might notice is an increased amount of smoke from the exhaust.

Its not as simple as capping them off, as the MAF will start reading higher values than it should off the throttle which the ECU detects and logs as a fault code (expcected air value). Needs software modifying IMO.

That will be mine then... WIIIIIIIDE OPEN...

Not quite sure what it was doing the other week on the M'way when the engine wouldn't rev over 3000rpm even in 4th! :confused: Lasted about 6/7 miles then returned to normal.

Been offered an EGR switch off + DPF removal + Map for £320 inc VAT at the garage I had some work done at the other week. Just don't understand why AHM is £400 more?!

I wish they'd give us AOers' a 10% discount!... :thumbs:

That seems like a good deal. There is a specialist auto tuner next to my work, might have a chat with them about the same.

seems the only one they have is....

Alfa Romeo 2.4 Jtd EGR Delete

looks like some restrictive and fully blocked gaskets ....and a pipe! ...why not just fit the gaskets on their own and blank it off at the manifold?

you're getting an ecu error either way i reckon.

Looks like it deletes the vacuum-controlled throttle flap as well. I had one made by Wizard and ran it for a while on a 2.4 10v that I used to own. It did make it a little noisier when turning off the engine.

So I've been on their website & searched eBay but can only find a kit for the 156 2.4?

I've since fitted one to my bora tdi & it's made no difference whatsoever to mpg or performance. The one thing I know it'll help though is to reduce the carbon build up in the inlet, which can't be a bad thing!

In the kit I got there was a solid plate to block off the exhaust feed pipe, new bolts & jubilee clips and a new gasket to fit between the pipe & inlet (& the pipe of course!). I haven't got any ecu faults showing on vagcom but it is an early tdi (non PD). I think the later engines, along with ours (both common rail) will throw up a fault & will need to be mapped out. Perhaps this is why one isn't produced for the 159?

I assumed the 156 was the same as the 159 but looking at the pictures on ebay and comparing them to my car, there does seem to be some differences.

I'm thinking of blanking my EGR off. The garage that worked on my car recently did this to another 2.4 and it worked a treat apparently. But read in an older thread that this can cause limp mode.

Any thoughts?
It wouldn't go into limp mode but it would register a fault.

Although the ebay post title says it's for the 2.4, lower down it says it's also for the 1.9; so does the 2.4 and 19 have the egr?

I'm also interested to find out if it throw's up an error or not before i buy.
