"chukka-chukka" - to rest!

"The EGR cooler receives exhaust gas ....blabla .... engine operation. At engine switch off the valve opens and closes several times to clear any deposits which may have accumulated during running."

Yup, we know what the "chukka-chukka" sound is, it's the "beep" that is mystery!

I've got to change my plea. It was very quiet for a change tonight when I switched off and I was actually ouside the car and reached in to turn off and remove the key. There is definitely a noise accompanying the chukkas. I don't think it's a beep like you'd get from a speaker or buzzer, it reminds me more of a small high speed servo motor finding its home position.

i wonder if this high pitched sound isn't just our ears singing after driving with the window open and our elbow hanging out.... www.ralton.co.za

No, I reckon that's the reason that most people can't hear it!

Now that I'm paying more attention, I am also hearing a similar beep when starting the landy. Turn on the ignition and while wait for the glow plug warning light to go out, have a good listen

Mine started to give me this chukka chukka sound after shut down the engine about a month ago and still it happening. Would it stop one day or could it be a fault?

I always had this as well, on ignition and after the chukkas x3. Seemed normal to me. Actually it psyches me up to fire up the Landy

This is the sound of the standard car, with EGR enabled... (Thanks Naks)

This is what our EGR shut mod does... Absolutely nothing!

You can hear a short high pitched, servo kind of noise. To be honest, this video was made early on this year, and I cannot remember what i had set the duration to. It's since been set to 50ms and so cannot be heard at all.

Over here we have no choice but to have an EGR to make the vehicle comply with various emissions legislation. People have had erratic running due to the EGR sooting up . There has been work done to remove the EGR or fit a "blanking plate"to effectively stop it doing it's job. Some say this gives smoother running but your ECU needs to be fooled into thinking that the EGR is still doing it's job. This is the difficult bit. Various experiments have been done with blanking plates with various size holes to get the smallest one possible to fool the ECU into thinking everything is normal. Don't think there is a perfect one yet. If your country does not have the same emissions legislation as us you probably do not need an EGR but if one is fitted to your Puma you are probably stuck with it until someone comes up with a solution for removing it, without getting fault codes etc from the ECU. There will be someone on later with more technical info so stay tuned. 1982 88" 2.25 diesel

I'm sure i can even hear a small "click" at the end of the high pitched beep, like a switch... www.ralton.co.za
