Regular twang revisited...

[GTI_PAPA]

Hey guys,

I think my original post has gone off on a tangent somewhat.

Let me explain what happens. On a cold start, I reverse out of my driveway (slight downhill+twist), and as i hit the twist, I apply the brakes slightly and a loud TWANG+vibration accompanying it. If i don't apply the brake, it rarely happens, but upon moving forward, I get a very light TWANG, every time (but only once after every cold start).

I asked the VW service guy about an ABS self test, to which he replied "Never heard of it."

Anyhow, thought I'd clear things up with regards to my issue.

Cheers.

Sound like ABS for sure its doing its job when it shouldnt be, self test???? that happens behind the scenes mate and wont cause a twang. Only time ive seen this is a maladjusted sensor on an A4, but you can set the position of its sensors, the Polo sensors are bolted on mate so that doesnt apply. A bit more than just a basic scan reqd i think, problem is you got to know what you are reading, thats where it all goes pear shaped.
cheers
