Got a prob......just fitted my new ptu yesterday and all seemed fine (no more engine cut outs) but today i've noticed a light keeps comming on my dash and iv no idea what it is! it looks like a pic of a tube that is fat in the middle and has 4 sqiggles above it (heat/steam?) this kept coming on and i thought i could here a slight popping sound, and then to top it off as i pulled off at a junction the thing went and cut out on me! does any one have any idea what it could be? Oh and i still getting the juddering when i put my foot down??? :confused:

It sounds like the cat overheat light

Hi,

 

That's generally caused by unburnt fuel igniting within your cats. Make sure the PTU and coilpack connections are clean.

Yep check those connections you made on the PTU :)

Vijay/Andy when you say clean them - what is the best stuff to use and is it a blueish corrosion I'm looking for? (is that spelt right?)

you can buy contact clean (spray can) http://www.maplin.co.uk/products/module.asp?CartID=10968905&moduleno=4153 from Maplins etc. You want to make sure the contacts are clean and bright :)

Slim, sorry to hijack, but I noticed that light coming on a couple of times today as well.

 

I have a new exhaust on, and it may be blowing a bit at the front (not investigated the blowing yet). Nothing else has changed on the car (especially relating to PTU).

 

What else can cause Cat overheat, and could it be connected to the exhaust blowing (e.g. hot exhaust blowing over sensor!?!)??

 

Cheers

Rich

Slim, I'll bring some up to the Leicester meet on Thursday if you like, other than that pop round my house and i'll show you what and where to clean.
