03 Boxster S Check engine light
Discussion
Hi,
I recently convinced my father to buy a 2003 manual Boxster S, which seemed like a good motor for 8k. It seems in great condition but the engine management / emissions light came on whilst test driving it. The small independent dealer (who was very helpful) that we bought it from sent it to his local specialist who replaced at least 2 of the lambda sensors and tightened the exhaust bracket (I believe the OBD codes suggested these were the problem). This seemed to sort it for a while. After owning it for about a month and doing a couple of hundred miles or so the light has come back on again, which co-incidentally happened just after filling up with super unleaded. The tank was not especially empty before refilling.
The dealer has suggested he takes it to the indy he uses in Kibworth Harcourt, Leics and following a conversation with them I think they intend to change the remaining two Lamda sensors. My reading on the net seems to suggest that failures of multiple sensors is unlikely and that the OBD codes may be misleading in that there could be another cause (MAF etc etc).
Is this a common issue and any particular problems to look out for? The dealer thinks it should be ok to drive around 20 miles or so to have it looked at again. The car is driving fine.
Thanks for any advice
Steve

Thanks for all the info folks - great to know there's so many genuine people out there offering assistance. He lives on the Lincs/Leics border and as he only bought it recently he did take it back to the vendor's indy who said the fault code reported a rear O2 sensor. He said he thought this was unlikely to be the issue, swapped them round and reset it. He reckons if it comes on again and it reports a different sensor it probably needs a new ECU, although from the above it sounds like it may just need an update.
Thanks again, will see how it goes. It seems an awesome car for 8k, considering I paid over 50k for my Cayman S, which is clearly a better motor but perhaps not THAT much better :-)
