So I have this issue that happens on my 2010 Focus (1.6 petrol) when I go over bumps at speed or swerving, doesn't happen at all on long straight roads, but when I take a country road at a nice fast speed every reasonable bump will cause it. It's not the typical suspension or ABS kind of clunking, but makes a sound a bit like Kerr Kerrrr Klunck


To me it sounds like a relay breaking, then clicking itself back into position and causing something else to clunk along with it. it's always sounds identical, never changes at all.


I've asked the garage to look at it several times when it's been in for other reasons and they've been completely useless. First time they said "We didn't do anything about it, but maybe they tightened something up when working" second time was "We lubed up the door hinges, that might fix it" and third they just didn't bother. Decided to take it to a different garage and the guy actually came out with me but he said it was just something loose and wasn't covered by warranty so he'd have to charge me.

It didn't sound like something rattling at all because the sound is always the same.


Anyone else had a problem like this before? It's very annoying and has happened ever since I got the car at 12 months old. I'm going to take it back to the first garage before the warranty runs out and insist on speaking to a mechanic to see if I can convince him to do something.

If its a relay sound it may be the Traction Control or ESP kicking in...

Whenever I go over a bump and/or the ABS kicks in briefly I get the same noise as when you first get when pulling away. Always just put it down to the ABS/traction control doing it's stuff.


Not sure if this is what you're describing?

I get the ABS noise if I go over a bump with my foot on the brake, but this one happens regardless and is a different noise. It doesn't seem to be doing anything wrong, may well just be the traction control I guess - any way to force the traction control to kick in so I can hear what it sounds like?


Thanks all!
