AFAIK all the EGR does is makes your engine eat its own poo to meet emissions so it doesn't need to be connected anyway.
Sure someone will be along to correct me/explain further if that is not the case..

Some newer cars have an ecu that calculates air flow via the MAF. When the EGR valve opens the MAF flow figure drops. Newer cars measure this drop. If it doesn't happen it assumes an EGR fault and puts the light on.
So on some cars you get a light and on most you don't.

I get the "Emissions Workshop" warning and when I start the car it goes to tickover and then dies. If I try to rev the car before it dies then there is no power at all. Does this sound like the EGR Valve?

You should get a code read. It will save time in the end. It could be the EGR jammed open. Take the pipe off and have a look. It should be closed when the engine is off. If not, push it shut, pull off the vacuum hose and block the hose with a bolt. If it now runs ok, you know the problem is the EGR.

Thanks for that, will get the garage to try that tomorrow.

Hi,

just an update on the issue.

The garage replaced the EGR valve and it started great. They took it for a test drive and was ok. They phoned me to tell me to pick it up. When I arrived the car had exactly the same issue. They put it back on diags and these are the error codes that it is now throwing up:

17932 P1524 Fuel Pump Relay (J17), Open or Short to Ground
17849 P1441 EGR Valve (N18), Circuit Open / Short to Ground
18027 P1619 Glow Plug / Heater Relay, Circuit Open / Short to Ground

They think it could be the connections on the injectors or a problem with the wiring loom.

I found a case online with these errors and it was a faulty solder joint on the ECU.

Any ideas would be much appreciated

Cheers

Dave

Try pulling the glowplug relay out and giving it a tap/shake and push back in. It is on the relay plate under drivers side dash. It should be blue, probably with 202 on it.

Hi Martin,

Thanks for that. We did take the relay out and reseated it. We also took the 167 relay out and took the cover off to make sure that it was working ok which it was.

We also took the rocker cover off and pulled off and re-connected the wires to the injectors - but still the same issue.

Cheers

Try checking the glowplug relay terminals for power. One is a live feed for the plugs, one is the relay energiser live. I can't remember which is which but it shouldn't be hard to work out.
OR more likelt check the terminal 30, ecu relay J317. (109). In the box under the bonnet. It should be possible to jump it and start the engine if this is at fault.

Hi Martin,

thanks a million for that. Will get onto the garage first thing monday to check this out.

Cheers

Dave
