Delay In Revs Coming In, Easy Stall - 2006 Tdci

7 posts in this topic

Hi

I have what is really just an annoyance at the moment, but wondering if anyone knows what might be causing it as it would be nice to resolve!

I have an early 2006 1.8 TDCi, and the problem is that when I pull up at a junction (for example) and then go to pull away after being stationery for a few seconds, the engine does not react to the accelerator peddle being pressed and I nearly stall. Prime example would be when I pull up, stop and then someone immediately flashes to let me out, I press the accelerator and start letting the clutch out and there's no more revs than tickover, so I have to wait a couple of seconds and then the revs kick in.

If I have been stationery for say 10 seconds it will be fine, so it's only when I have just stopped and literally go to pull away again.

Not seeing any other issues except for a flattish spot around 1500-1700 rpm where it feels a bit hesitant and jerky at times, but I suspect this is roughly where the turbo kicks in.

Mileage is around 75,000.

Any thoughts?

It could be a lot of things -typical reasons are - the turbo actuator/ VNT vanes could be sticking (usually due to the vanes being coked up, over time) or you have a split boost hose - cat or dpf (if fitted) blocked - generally the hesitation is probably due to loss of boost

EGR valve could be leaking

Are you getting more smoke out of the exhaust than normal? have you had the fault codes read?

When was the last time the car was serviced? changing the fuel and air filter may help, and won't cost loads, and needs to be done eventually anyway - so best to do this 1st (if not recently done) rather than spending money you don't need to - garages/ Ford can have ridiculusly long service intervals - you can put your car in for a "service" and they miss things out (like the fuel and air filter) and still charge you a fortune!

Sometimes a good "italion tune up" helps & driving sedately makes things worse

Thanks for the reply.

Yes that was my concern that it could be any number of things rather than something definitive.

Didn't want to go down the route of trying this, that and the other to see "is it any better?".

In answer to your questions:

No more smoke than usual.

Annual service is due in July (approx 7K since last service).

I believe that the fuel filter was changed at the last service, but I would need to check the job sheet to confirm this.

I do tend to stay below 3500rpm, so will give it some beans when the opportunity arise on the way home.

Thanks for the EGR idea. I gather it's a popular mod with benefits anyway, so definitely worth doing.

I've brought one from eBay, will fit this weekend.

Fitted the EGR blanking plate and I it appears to have done the trick.

Thanks for the advice!
