this is a bit long, but we need help... the oil temp seems high around 110 without driving hard or going over 3000 revs. normally for me the temp is around 90. this happen after a service from Audi who fixed it by replacing the oil. my next service was with non-audi garage and it happened again - oil temp between 110-120. I had the cam-belt, water pump and all the normal bits replaced and still oil temp running high around 110. normally with the oil temp at 90, it would rise to about 110 if I pushed it but I am not keen to push it at the moment. in fact I am not driving it. work so far: 7 months ago --- Service - oil temp between 110-120 --- replace oil - oil temp normal 6 months ago --- replaced MAF - oil temp normal 1 month ago --- Full service - oil temp between 110-120 --- cam-belt changed / water pump - oil temp between 110-120 --- replaced oil with Shell Oil - oil temp between 110-120 --- replaced oil with VW Quantum Oil - oil temp between 110-120 fortnight ago --- replaced the oil with Shell Ultra - oil temp around 110 last week --- replaced water temp sensor - oil temp around 110 --- replaced oil sensor - oil temp around 110 (dose anyone know how the oil temp is worked out..? I've been told the original S4 had the temp taken from the oil temp sensor, the facelift dosen't have this sensor just an oil sensor that the ECU uses to calculated the oil temp with other sensors, if so which ones..?) is this right...? --- replaced the water pump - oil temp around 110 another thing I've noticed, when at the petrol station the water temp would normally be at 90.? (well 12 o'clock) but sinse this problem after I paid for the petrol adn returned to the car the water temp is near 100. I've never seen this go above 90 (12 o'clock). I have Audi service the S4 every 6 months and a full long life service every year. I've searched here and on RS246 and couldn't see any issues like this..? I use the misses little Astra at the moment which is only a few years old and great on fuel but so, so powerless... I had Mr DTi cut me up last week and had to let me go... HELP ME...!!! Audi are now not sure what to do next and now saying this is normal, but will look at this further if I want. The only other bits I can think of is the ECU or dash its self but both expensive to replace and not sure how to test them. Audi said these would show error codes if there was an issue with them...? Its got to be somthing the service causes... but what and why...? any ideas...?
