Help and guidance needed please

I have had my car inspected and have been told the EGR valve is seized and instead of getting a new one just block it off by taking the hose of the valve and putting a bolt in it.

I've looked for a EGR delete kit but because mine is the late type EGR valve which is connected to the ECU I cannot fit a delete kit.

Looked around for a replacement EGR valve and the cheapest I found one for is £137.Do I need to fit a new EGR valve? Is there a possibility of doing harm to my engine and fuel economy by not having one? Or is there a EGR delete kit available for my engine.Its a 2006 VRS and I've been told it has the late type EGR valve.

The EGR valve on these often clog up due to the exhaust soot mixing with the oil vapours from the crank case breather.

 

Have you not considered removing the EGR and cleaning it to see if it frees it up? It will more than likely be caked in crud and gunk which is causing the issue. 

 

It's a messy job to clean it though so marigolds, a few cans of carb cleaner and something to scrape the inside (flat blade screwdriver works well) will be needed. 

 

I'd also recommend you search the 'elephant mod' which will prevent the build up of crud in the future. Chances are the inlet manifold will also be caked so it's up to you if you want to clean that at the same time... but it is a bit more involving.

I have been told that the diaphragm has gone on it otherwise it could have been cleaned and put back together like what you suggested.What would happen if I continue to drive with the hose blocked?

What ever route you decide to go down I'd get it sorted properly. Putting a 'bolt in it' sounds like a bodge job and it will more than likely throw an engine light as a minimum. I can't see it causing any major issues short term but your fuel economy will likely be poor. 

 

You have 2 options:

 

1. Purchase an EGR delete kit from the likes of darkside developments. Fitting is relatively easy but there are two different sizes (51 and 57mm) I'm not sure myself which size you would need to retain the original pipework. You may also need the EGR cooler delete pipe, some people say you don't need it and can use the existing pipework. Cost for both your looking at ~£75

 

2. Buy a new EGR valve, fit and then either do the elephant mod (to remove the oil vapours and prevent clogging up) or have the valve mapped shut (which can be done when remapping the car and is essentially the same as an EGR delete without removing the valve, the ECU just has the parameters set so it never opens.)

 

The issue with an EGR delete on the newer BLT engine is that the EGR unit also houses the anti-shudder valve which also gets deleted as it's part of the same unit. 

 

Personally I'd go option 2, as there are negligible benefits to be had by doing a delete and it's a bit more hassle than just swapping out the valve.

 

A 3rd option would be to have a go at cleaning your valve, it is very common for them to clog up and seize. It's also the cheapest option if you can DIY it. I wouldn't bother paying someone to do it mind and just replace it if that isn't an option. 

Your engine will be a BLT like mine with it being a 2006. The anti shudder valve is separate so you can retain it with the right egr delete setup. I bought mine from darkside.

You will need the egr turned off though in the ecu else you will get a fault light on your dash. Shark did mine at the same time as mapping.

You can leave the egr cooler in place to save you having to mess about with your coolant pipes but I took mine out.

This is what I have fitted

If you go down the replacement route then this will save you a few quid...

 Has anyone tried to shut the EGR down on a VRS using EDC15P software. I have done this on my 1.4 TDI as it is just a case of flattening the map.
