Zafira 1.9TDH EGR valve

The bad news is that the intake manifold is likely clogged, and the swirl flaps partially stuck or sticking as a result. Sadly it's almost impossible to clean these manifolds and when the swirl flaps jam and break the actuating rod, you have to replace the manifold. This is about a 5-6hr job as alot of dismantling is required.

I always recommend a remap to remove EGR operation, which is an additional cost, but if you are planning to keep the vehicle, it's worthwhile as you will be back in the same situation after a similar mileage.

Sorry.

Thanks(?) for the information.

My immediate problem is whether it's advisable to go on holiday with the engine in its present state. A breakdown in Europe would be awkward,to say the least. I've already driven a couple of hundred miles since the warning light first came on.

Wouldn't removing EGR operation affect the emission levels, and therefore fail the MOT?

I'm no expert but I think the answer to that is "yes, but not much"

and consequently "probably not".

Or quite a lot but they don't currently measure it. EGR mainly reduces NOx.

The worst that will happen is it will enter LOS mode and ~45mph. it wont just stop.

Deleted EGR will result in a cleaner exhaust marginally improved mpg and drivability, but higher NOx levels under certain conditions. There is NO negetive effect on MOT testing.

I've been told (by a Vauxhall mechanic) that the engine could possibly just stop. Anyway, I certainly don't fancy being restricted to 45 mph among those lunatic tailgating Dutch drivers.

I've decided to bite the bullet and in it goes to the local dealer first thing tomorrow, as I have to have it properly roadworthy on Saturday morning. Perhaps they'll give me an OAP discount on top of the 10% I already get...

Thanks again for the info.
