Ive recently had some work done on my 93 series 3 Thema which included the replacement of a broken ABS sensor. Prior to this the ABS warning light stayed on all the time. Now however the Warning light does not come on immediately but will come on 5 to 10 minutes into a Journey particularly when cornering.
Any Thoughts?

Re: ABS sensor
Fintan,
One of the members of the UK Lancia Thema Consortium experienced a strange ABS problem that I've copied below (for the full information visit the website - www.lancia-tdc.co.uk)
"Here is a snippet of information that may be useful to all you Thema owners with flashing warning lights. Some time ago, for no apparent reason, the abs warning lamp started coming on in my S1 turbo. This was usually after moving off and attaining a speed over 20 mph. This indicated a fault with a sensor however the peculiar aspect of it all was that the warning light did not always come on. Sometimes it stayed off for days and would then reappear for weeks at a time. Inevitably although I always intended to get to the root of the problem I never did, just suffered the warning light.
Then on a trip to the south of France I noticed that there was a degree of wheel vibration at speeds in excess of 90mph. So before my return I went to a tyre shop and asked them to check the wheel balance. The fitter then noticed on spinning up the offside front wheel that the tyre, although in otherwise good condition, had developed a flat spot and was running therefore in an elliptical motion. This meant of course that he could not balance the vibration out and the recourse was a new tyre. This was duly fitted and lo and behold no abs warning lamp! And this has remained the case ever since. I can only assume that because of the flat spot on the tyre it was telling the sensor that the wheel was momentarily locking up and therefore as the brakes had not been applied assumed that the system had gone down and was switching it out. Anyway whatever the technicalities the problem is now resolved. So whatever you do check your tyres first!!"

Re: ABS sensor
Hi Angle!!
I took your advice, monitored my speed for the last few days. The Warning light comes on after about
5 minutes irrespective of what speed i'm doing.
Any other ideas?
