I really hope someone can help me here.

I get a red warning light coming on and this just started recently. i have a 1990 TT and i have noticed since this light started coming on my car has seemed to slowed down - i think the turbo isn't actually kicking in? I am not sure but i am assuming its maybe a turbo warning light? It looks a little funny.. kinda like a square with 2 bits coming out either side and seems like its trying to show something is overheating? Maybe someone here has seen it before and can suggest something? i did try search the 'technical' stuff but when you dont know what you are looking for its hard! hope i can get some good advice.... As i'm a fairly new Zed owner i aint very 'wise' on these cars yet! Thanking everyone in advance...

do a search for "cat overheat" light :)

Any help ??

Hi bud, and welcome. :)

 

As Vijay has said it sounds like the Cat Overheat Light (Middle lamp of the row of five just below the temp gauge, as seen on the link Alan has posted above).

 

This generally indicates that you are getting excessive heat build up within the cat/s. This will be excess unburnt fuel going into the cat/s and being burnt there with the very high temperature within it.

I had this on my Zed, and it took me ages to rectify it. I changed the PTU, as this is a very common item to fail on a series one car (and early series twos as well). I changed this over to a series two PTU (do a search for PTU, the visual differences was covered just last week) but that didn't cure it on mine. I also changed over my Coil Pack connectors, as these can become brittle and become loose, but this didn't cure it either.

In the end I found my fault by chance. I was checking the plugs over and noticed that one of the Coil Pack rubber sleeves was very badly split On closer examination I could see were the spark was shorting through this split directly to earth, thus I was loosing power on hard acceleration!! One new Coil Pack later and alls well.

 

Anyway, I hope I've given you a few pointers to look for. Check out your Coil Packs and the plastic connectors on top, if alls well here, it could be (but isn't a definite) the PTU breaking down under load (this is caused by heat and dry solder joints within the unit)
